Bitcoin Diamond Wallet stuck syncing

Currently says 12 days behind and 98% sync. I have blown away my copy of the blockchain and re-downloaded but still gets stuck in the same place after a few days. Any ideas on how to resolve?

Bitcoin Core Wallet Sync stuck on 0 hours behind!

Hey guys, I'm pretty new to bitcoin, installed the wallet about a week ago and had it sync'd and working fine but then today it went out of sync. It's stuck on 0 hours behind. Anyone have any idea how I can fix this? It's been sitting at this level for about 8 hours.

Re-covering Monero wallet

So I had my TAILS set up on a usb disk and it got into an unfortunate accident.
I restored my TAILS and got my Bitcoin wallet back thankfully but my Monero wallet is now having issues.
I redownloaded the Monero guinfrom getmonero and did the command prompt stuff but it never connects. I set it up both trying root and regular. No luck.
I have my seed and block height and the farthest I have gotten was it stuck on "Synchronizing" and the one time it got through to "Connected" itfroze before it was completely synced.
I noticed it was a different version I downloaded though. Could that be it? I doubt it but idk why I can't seem to connect to the network.

Nothing is connecting taking forever to load wallet...

Just transferred some bitcoin to this wallet address and its taking forever to sync... Stuck on "loading a block." How long am I suppose to wait for it too load/connect everything. I guess I can look into the logs but even then I'm drawing blanks on what the issue even is.

Unable to move claimed BSV from ElectrumSV wallet (imported privkey)

Hi All,
First post on Reddit, but a long time reader and a bitcoin novice, despite having coins since ~2014!
I finally got around to claiming my BSV from my BCH. At the time of the fork I know what my balance of BCH was and therefore what I expect my BSV to be (1:1).
I can see this value in my ElectrumSV wallet after importing my private key for my BCH address. My BCH wallet is BitCoinABC and is fully in sync. However, when I try and send and BSV from my ElectrumSV wallet to a recipient, I get the 'Conflicts with one already in the server's mempool' error (\n\n258: txn-mempool-conflict).
I should say that I initially claimed these coins approx. 30 hours ago now and have successfully exchanged a small amount of BCH to BSV and sent it to the wallet that has the claimed coins in it. The small transfer is now also stuck in that wallet.
Research tells me I probably need to make a raw transaction to create a double spend, but this is beyond my current ability... either that or wait for the block height to catch up, which I would have thought may have have happened by now, looking at the block height differences between BCH & BSV?
So any help or pointers would be appreciated...
TIA


++EDIT++
Thanks to Deminero30 this has been resolved and the BSV recovered to a functional address!

Redeeming coins from old bitcoin core wallet

I bought some bitcoin a few years ago and put them into a bitcoin core wallet on my laptop, and forgot about it. My laptop isn't big enough (memory wise) to download the Blockchain, and is stuck trying to sync with over 2 years to go. It also tells me to update the software? What should I do? I've backed up the wallet onto a memory stick, can I move it to another wallet still? Tried to Google it and they say it's possible but they talk about keys?? I don't know how to know what my key is?

Zap rant : List my coins

About 3 week ago I downloaded the Zap wallet on my PC. At first the installation went fine but once I reached the sync process, I was stuck at 100% but nothing happened. I left for the entire night but it still wouldn't go pass the sync page. I opened an issue on [GitHub](https://github.com/LN-Zap/zap-desktop/issues/3334

I found an old wallet and recovery.txt file, but I'm clueless what to do.

Update:
Seems to be an empty BitCoin wallet. Thanks to Im_Here_To_Fuck for the help.
For those wondering: I took the wallet.dat and used PyWallet to get a wallet.txt file, which gave me a bunch of lines filled with ADDR, PUBKEY, RESERVE and SEC information.
Based on that, it looks to be a Bitcoin wallet. I already have Bitcoin Core installed and Syncing, it's about 4 years behind as of this edit. No transactions showing right now with the wallet.dat replaced.
I checked Bitcoin explorer for about 30 of the addresses listed - no transactions.
Better to know its empty than wonder forever!
The files are from 2013 and I don't have a clue if there is even a balance. I don't even remember what currency it was for or what the wallet belongs to.
I ran PyWallet but it didn't really clarify anything for me - I think it may be LiteCoin but I'm still stuck - what now? How do I actually get into the wallet or better yet how do I figure out what wallet the recovery code is even for?
Any help would be much appreciated.
Thanks
edit: I also noticed I found a debug.txt file and there are dates from 2009 / 2010 in there.

Using the Internet to Donate to Andrew Yang - Cryptocurrency, BAT, and the Brave Browser

Hi y'all,
Yesterday, I stumbled across a post on this sub that piqued my interest in alternative methods of donation. While most candidates have mentioned very little (or nothing) about cryptocurrency, Andrew Yang has a future-oriented policy outline posted on his campaign website (https://www.yang2020.com/policies/digital-asset-regulation/). As the most technologically capable candidate, it's time that we add cryptocurrency into the mix of contributions to Yang's campaign. Although crypto's relative anonymity poses a few challenges with campaign finance regulations, there is a way that we can put crypto to work legally and effectively to support Andrew.
This post will focus on the usage of the Brave browser and the associated utility token, BAT (Basic Attention Token.) Brave is a web browser developed by a team lead by the creator of JavaScript and co-founder of Firefox. The project is focused on issues such as data ownership, privacy, and security. In general, it meshes well with Yang's policies. One of the unique features of Brave is the ability to earn BAT by enabling ads. Brave blocks ads by default, but users can opt-in to receive pop-ups for relevant ads based on locally-stored browsing data. These are shown as a small notification at the edge of the screen, typically at a rate of no more than 5 per hour. For each ad shown, the user will be paid in BAT. Earned BAT are deposited into your wallet once per month, normally around the end of the first week.
After payment, there are multiple options:
Here's how to earn BAT using Brave to support Andrew:
  1. Download Brave browser. Note: There is a referral program for browser downloads. By using a referral link, the referrer will earn $7.50 after ~30 days of use by the downloader. I know that many of us here will happily pass this along to to Yang campaign! ☺️ Work together to utilize this benefit. In order to generate a referral link, you must sign up to be a Brave creator at https://creators.brave.com/. As Reddit users, all of you are capable of signing up to be a creator!
  2. Opt-in to Brave ads following the instructions at https://support.brave.com/hc/en-us/articles/360026648512-How-do-I-opt-in-to-Brave-Ads-
  3. Set up your account at Uphold. You must verify your identity using a driver's license, passport, etc. There are regulations in the US related to knowing your client that Uphold must follow. Initiate this process by clicking the Brave Rewards button > "Verify Wallet" to the right of the address bar. (It's an orange/pink/purple triangle.) This should bring you to uphold.com where they will guide you through creating an account.
  4. After your account is verified on Uphold, ensure that your Brave wallet is synced with Uphold. The "Verify Wallet" text should update to say "Wallet Verified". Your earned BAT will now sync to Uphold.
  5. Once you have BAT in your Uphold wallet, there are a couple of options to get this money to Andrew:
    1. Withdraw to your bank account. You will then use the standard method for donating to Andrew Yang at yang2020.com/donate. Note that there will be a bit of a delay between withdrawal and funds arriving in your account. Uphold also has a 1.95% withdrawal fee.
    2. Convert to Bitcoin on Uphold and donate using CryptoFWD.org. This option allows you to use crypto for the entire process. This is the most "futuristic" option, but be aware that you are donating to a super PAC instead of the campaign directly. CryptoFWD is associated with u/HumanityFWD (HumanityFWD.org). They have posted some background on their organization at https://www.reddit.com/YangForPresidentHQ/comments/cl7cqj/the_humanity_forward_fund_the_yanggang/?utm_source=share&utm_medium=web2x. This is a great option for anyone who has reached the legal donation maximum.
  6. Keep using the internet as normal! Earn BAT and continue to donate your rewards.
Please let me know if you have any questions! I know this reads like an ad for multiple items, but I'm really hoping that we can use this technology to continue Andrew's momentum.
___
TL;DR
  1. Download Brave browser (using a Yang supporter's referral code if possible.)
  2. Earn BAT (cryptocurrency) by viewing ads - check out this link for an example ad. You won't be stuck with unskippable 10 second videos or anything, it's basically a push notification.
  3. Convert BAT to USD and donate to Andrew OR convert BAT to BTC and donate to CryptoFWD.

[SPV node] Able to synchronize headers on mainnet

[SPV node] Able to synchronize headers on mainnet submitted by LolaDam to Namecoin [link] [comments]

Bought bitcoin at a bitcoin ATM machine yesterday and the first few confirmations went quick, but then it got stuck at 3 confirmations for the past day. Not sure what to do.

Looks like in order to actually be able to use the btc I bought, it needs to get to 6+ confirmations in the wallet before I can spend it. The first few confirmations went fine, but then once it got to 3 confirmations it's just staying stuck at 3 confirmations for some reason. It's been almost 24 hours now.
If this is fairly normal during high traffic times (maybe because bitcoin price just plummeted right during the middle of this), and I just have to wait a day or two, then that's fine, it's not super urgent, albeit a bit annoying.
But, if this amount of time of it being stuck at 3 confirmations is an indicator that it will be permanently stuck and I will just literally never have it get to 6+ confirmations, and essentially lose the cash I spent on trying to buy it from the ATM, then, obviously that would not be okay, and I'd have to try to do something about it (if there's anything that I can do, that is).
:(
edit: yea it appears there was/is some sort of syncing issue with the wallet

Andreas Antonopoulos' depiction of the day he became aware of the donations that made him a millionaire

I'm not sure if this already has been posted here, but I just came across this post from A. Antonopoulos' Patreon page (it's a public entry posted on 16th of December. The readability and formatting is better there btw):
Edit: direct link to the post: https://www.patreon.com/posts/emotional-15912702
On December 6th, my life changed trajectory... again. I went to sleep on a wave of positive messages and support from the bitcoin community, in response to a letter I had posted on Patreon titled “In defense of optimism” that had leaked to Reddit. I had spent the day reading messages of support pouring in on Twitter, Patreon, and email, literally thousands of them. It was a life-affirming experience. Like everyone else on social media, the messages I receive are not always kind and supportive. Often the critical messages and trolls are far louder than the supporters. Our brains don't evaluate praise and criticism in equal measure - it's easy to believe the criticism and see the praise as undeserved. That’s why each little message of support makes a difference, each one helps me ignore the critics and see the impact of my work. In addition to all of the written messages, people were signing up to support me on Patreon and some were even sending bitcoin to my donation address. By the time I went to sleep, I was filled with gratitude, humbled by the overwhelmingly positive, viral response of the community.
Here’s what happened next...
I wake up on December 7th, the notifications list on my phone was too long to scroll. Hundreds more messages of support had come in while I was asleep.
Then my phone rings and I recognize the number of a dear friend. "Strange," I think. I’m not expecting a call. "Don't open your laptop yet," she says. "You got some big bitcoin donations overnight. Are you sitting down?" I sit down. I open my laptop, I look at the balance in my 1andreas bitcoin donation address.
Surprise, gratitude, fear, shock, joy, elation, anxiety. My emotions achieved a level of volatility that mirrored that of the bitcoin exchange rate. Good thing I was sitting down.
You're probably thinking that between the supportive messages and the large donations, I’d have been celebrating without a care in the world. But I'm a security professional who works in bitcoin. Could I come up with a doomsday scenario to taint this experience? Hold my beer.
I'm in a taxi on the way to the airport. I’m cycling through emotions again, a bit faster now.
Joy, Terror, Tears, Gratitude, Fear, Elation, Dread, Cold Sweat. It's a good thing I'm sitting down. I can't feel my fingers.
Anxiety
Wouldn't it be ironic if I get hacked and this massive donation is stolen the same day it was given? Shudder. That was a real possibility. Funds were sent to a vanity address, posted on my website, which was mainly used to support my habit of giving small amounts of bitcoin to strangers at meetups and conferences. Before December 6th, the address typically received small gifts each month and I emptied it every now and then in a spree of small donations.
Gratitude
I still can’t believe how many people have responded. I had no idea how many people could identify with the feelings expressed “In defense of optimism” and would want to show their support. I’m grateful to be a part of this community.
Fear
This vanity address is secured with a single private key which was stored on my phone in a “hot” wallet, so that I can give away bitcoin at meetups. The address has maximum public visibility and no Segwit (segregated witness) support. My security model just tipped over and I'm freaking out.
Happiness
I’m so happy! This is incredible, unimaginable. My fingers are numb, in a good way. Is this really happening?!?
Cold Sweats
I have to move the funds out. Now. Right now. But I only have this key on a wallet that doesn't handle RBF (replace-by-fee), CPFP (child-pays-for-parent), and it's not a Segwit address. I'm traveling; I’m about to get on two long flights and the mempool is slammed with transactions. Of all the days!
Joy
I’m crying. Tears of joy. This is something most people never get to experience in the most meaningful of careers, a loud acknowledgement from an entire community and financial security. I’m thinking about my family members and close friends who are struggling and overjoyed at the opportunity I now have to help them.
Terror
Then it dawns on me: a perfect nightmare scenario. What if this is considered "income" in the US and I have to pay taxes at a 39.6% rate? Those taxes would be evaluated on the USD value of the donation at the time it was made, at an all-time-high price of bitcoin. If bitcoin's bubble bursts by 50% today, I will owe more taxes than the donation is worth. I will be bankrupt but will owe the IRS and those debts can't be discharged in bankruptcy. I'm going to be in debt for a decade!
Elation
I can HODL! I don’t have to keep selling to pay bills. Patreon has grown too, so I should be able to cover my expenses and build the business with their support. I can really HODL!
[Alarm buzzes on my phone]
“Boarding on Gate D15”. Pack everything back up, run to the gate. Find my seat. Unpack all my electronics. Re-establish connections. No Wifi yet. 3G if I hold my phone just so against the window. We're taking off. No Wifi at all on this flight. 4 hours, offline, me and my thoughts. What is the opposite of a state of mindfulness? Head spinning.
Fear
What if the price crashes. Should I sell some?
Silliness
I'm buying a lambo (I laugh out loud at the thought of that. No, I'd never waste money on something so silly).
Dread
What if the donations had zero fees and will never confirm? What if this was all a cruel joke?
Joy
My dad will be so proud!
[Landed]
Turn on smartphone. Too many notifications. Turn on VPN, Tor. Sync wallet. Too slow. Too slow.
Run to the lounge. Get on Wifi. Fire up VPN, Tor. Start electrum. Import keys. Child-pays-for-parent the stuck transactions, Replace-by-fee new transactions. Careful coin selection. Send to cold storage (so glad I keep an unused cold storage address handy). Overpay fees more than ever before. 2000 satoshi per byte? Fuck yeah. This is the highest priority transaction of my life. 8 agonizing minutes. 1st block. Confirmations ripple down my screen. Exhaling... I hadn't noticed I was holding my breath.
“Boarding gate C51”. Pack everything, run to the gate. Board the plane. Unpack everything. This flight has Wifi. Bet it doesn't work. Yup, it doesn't work. 6.5 hour flight. I'll just read a book. I've read the same paragraph 8 times and don't know what it says. I'll sleep. Nope. Ok fine, I'll fret - seems I'm good at that and nothing else right now.
[Landed]
That was the longest flight ever. Boot up, 4G, VPN, Tor. Sync.... slow, too slow.
ANOTHER GIANT DONATION. WTF! Is this really happening? Is my wallet counting the balance incorrectly? This isn't possible. WTF IS GOING ON?
Joy, Terror, Tears, Gratitude, Fear, Elation, Dread. I’m cycling faster now.
I just emptied my wallet into cold storage and now it's carrying a ridiculous amount again. Boot up, VPN, Tor, Electrum, CPFP, RBF, cold sweat, 1 confirmation. Phew.
I realize that I just conducted the 4 biggest transactions of my life. I'm shaking. Hope I didn't screw anything up.
Finally I get to my hotel. “Long day” doesn’t even begin to describe it. I am grateful, giddy, jetlagged and exhausted, so sleep should come easy, right? Not happening. Two hours of tossing and turning while my mind is racing. In the end I just pass out from exhaustion. I wake up in a state of anxiety.
I open my inbox. I have a dozen interview requests from newspapers, TV, radio. They don’t want to talk about bitcoin. They want to talk about “my story.” It’s never been about “my story” and I’m not about to change that. Denied, denied, denied. That’s it. I’m going offline for a few days. I need time to process everything that has happened over the past couple of days and strategize about what to do next.
There are no words to adequately convey my appreciation, my gratitude.
These are life-changing gifts, but I don’t intend to change my life. I’m highly suspicious and careful about “lifestyle inflation”: I resist any urges to increase my spending as my income increases because as a self-employed entrepreneur I know my income can decrease significantly at any moment.
First, the practical side: For legal and tax reasons the gifts should remain mostly untouched for at least three years. This is a new situation and no one knows for sure how the authorities will characterize it. I wanted to HODL anyway, so that’s fine with me.
Second, and the much more important side, I love what I do. I’m obviously not going to “retire” or slow down. Receiving your messages and support has energized me and I’m excited to do more, much more.
The number of people supporting me on Patreon has grown significantly and with that support I’ll actually be able to do a lot more. And there are many things I want to do: a new website with more materials, in as many formats and languages as possible; more books; an epic tour; and that’s just the beginning! I also plan to grow my team, which serves two goals: I can get help for the things that need to be done, but I can also bring more people success and security with a steady paycheck.
While I’m excited about all of these new projects, I want you to know that the ultimate goal remains the same: to educate as many people as possible about this transformational technology and remain an independent voice, working directly for the community.
A week has passed. The one feeling that keeps returning, among the barrage of feelings, is gratitude. After taking time to process and calm down, the fear and stress is gone and all that is left is gratitude. I am so thankful for all the messages of support. I am so touched to hear stories of how my work has affected others in a positive way. I am thankful for all the donors who rallied behind me to help me in my advocacy and education.

THANKYOUBITCOINCOMMUNITY

Thank you for being so generous, so kind, so supportive; I’ll never forget this experience. Now, back to work!

Problems checking wallet, bitcoin core on another server

So my setup is that currently Bitcoin core is running on a Windows server, and joinmarket is a fresh install on debian. Bitcoin core is a full node, no pruning, fully synced. I had some problems opening up RPC but I think that part works now (no longer getting timeouts).

Searching for the Unicorn Cryptocurrency

Searching for the Unicorn Cryptocurrency
For someone first starting out as a cryptocurrency investor, finding a trustworthy manual for screening a cryptocurrency’s merits is nonexistent as we are still in the early, Wild West days of the cryptocurrency market. One would need to become deeply familiar with the inner workings of blockchain to be able to perform the bare minimum due diligence.
One might believe, over time, that finding the perfect cryptocurrency may be nothing short of futile. If a cryptocurrency purports infinite scalability, then it is probably either lightweight with limited features or it is highly centralized among a limited number of nodes that perform consensus services especially Proof of Stake or Delegated Proof of Stake. Similarly, a cryptocurrency that purports comprehensive privacy may have technical obstacles to overcome if it aims to expand its applications such as in smart contracts. The bottom line is that it is extremely difficult for a cryptocurrency to have all important features jam-packed into itself.
The cryptocurrency space is stuck in the era of the “dial-up internet” in a manner of speaking. Currently blockchain can’t scale – not without certain tradeoffs – and it hasn’t fully resolved certain intractable issues such as user-unfriendly long addresses and how the blockchain size is forever increasing to name two.
In other words, we haven’t found the ultimate cryptocurrency. That is, we haven’t found the mystical unicorn cryptocurrency that ushers the era of decentralization while eschewing all the limitations of traditional blockchain systems.
“But wait – what about Ethereum once it implements sharding?”
“Wouldn’t IOTA be able to scale infinitely with smart contracts through its Qubic offering?”
“Isn’t Dash capable of having privacy, smart contracts, and instantaneous transactions?”
Those thoughts and comments may come from cryptocurrency investors who have done their research. It is natural for the informed investors to invest in projects that are believed to bring cutting edge technological transformation to blockchain. Sooner or later, the sinking realization will hit that any variation of the current blockchain technology will always likely have certain limitations.
Let us pretend that there indeed exists a unicorn cryptocurrency somewhere that may or may not be here yet. What would it look like, exactly? Let us set the 5 criteria of the unicorn cryptocurrency:
Unicorn Criteria
(1) Perfectly solves the blockchain trilemma:
o Infinite scalability
o Full security
o Full decentralization
(2) Zero or minimal transaction fee
(3) Full privacy
(4) Full smart contract capabilities
(5) Fair distribution and fair governance
For each of the above 5 criteria, there would not be any middle ground. For example, a cryptocurrency with just an in-protocol mixer would not be considered as having full privacy. As another example, an Initial Coin Offering (ICO) may possibly violate criterion (5) since with an ICO the distribution and governance are often heavily favored towards an oligarchy – this in turn would defy the spirit of decentralization that Bitcoin was found on.
There is no cryptocurrency currently that fits the above profile of the unicorn cryptocurrency. Let us examine an arbitrary list of highly hyped cryptocurrencies that meet the above list at least partially. The following list is by no means comprehensive but may be a sufficient sampling of various blockchain implementations:
Bitcoin (BTC)
Bitcoin is the very first and the best known cryptocurrency that started it all. While Bitcoin is generally considered extremely secure, it suffers from mining centralization to a degree. Bitcoin is not anonymous, lacks smart contracts, and most worrisomely, can only do about 7 transactions per seconds (TPS). Bitcoin is not the unicorn notwithstanding all the Bitcoin maximalists.
Ethereum (ETH)
Ethereum is widely considered the gold standard of smart contracts aside from its scalability problem. Sharding as part of Casper’s release is generally considered to be the solution to Ethereum’s scalability problem.
The goal of sharding is to split up validating responsibilities among various groups or shards. Ethereum’s sharding comes down to duplicating the existing blockchain architecture and sharing a token. This does not solve the core issue and simply kicks the can further down the road. After all, full nodes still need to exist one way or another.
Ethereum’s blockchain size problem is also an issue as will be explained more later in this article.
As a result, Ethereum is not the unicorn due to its incomplete approach to scalability and, to a degree, security.
Dash
Dash’s masternodes are widely considered to be centralized due to their high funding requirements, and there are accounts of a pre-mine in the beginning. Dash is not the unicorn due to its questionable decentralization.
Nano
Nano boasts rightfully for its instant, free transactions. But it lacks smart contracts and privacy, and it may be exposed to well orchestrated DDOS attacks. Therefore, it goes without saying that Nano is not the unicorn.
EOS
While EOS claims to execute millions of transactions per seconds, a quick glance reveals centralized parameters with 21 nodes and a questionable governance system. Therefore, EOS fails to achieve the unicorn status.
Monero (XMR)
One of the best known and respected privacy coins, Monero lacks smart contracts and may fall short of infinite scalability due to CryptoNote’s design. The unicorn rank is out of Monero’s reach.
IOTA
IOTA’s scalability is based on the number of transactions the network processes, and so its supposedly infinite scalability would fluctuate and is subject to the whims of the underlying transactions. While IOTA’s scalability approach is innovative and may work in the long term, it should be reminded that the unicorn cryptocurrency has no middle ground. The unicorn cryptocurrency would be expected to scale infinitely on a consistent basis from the beginning.
In addition, IOTA’s Masked Authenticated Messaging (MAM) feature does not bring privacy to the masses in a highly convenient manner. Consequently, the unicorn is not found with IOTA.

PascalCoin as a Candidate for the Unicorn Cryptocurrency
Please allow me to present a candidate for the cryptocurrency unicorn: PascalCoin.
According to the website, PascalCoin claims the following:
“PascalCoin is an instant, zero-fee, infinitely scalable, and decentralized cryptocurrency with advanced privacy and smart contract capabilities. Enabled by the SafeBox technology to become the world’s first blockchain independent of historical operations, PascalCoin possesses unlimited potential.”
The above summary is a mouthful to be sure, but let’s take a deep dive on how PascalCoin innovates with the SafeBox and more. Before we do this, I encourage you to first become acquainted with PascalCoin by watching the following video introduction:
https://www.youtube.com/watch?time_continue=4&v=F25UU-0W9Dk
The rest of this section will be split into 10 parts in order to illustrate most of the notable features of PascalCoin. Naturally, let’s start off with the SafeBox.
Part #1: The SafeBox
Unlike traditional UTXO-based cryptocurrencies in which the blockchain records the specifics of each transaction (address, sender address, amount of funds transferred, etc.), the blockchain in PascalCoin is only used to mutate the SafeBox. The SafeBox is a separate but equivalent cryptographic data structure that snapshots account balances. PascalCoin’s blockchain is comparable to a machine that feeds the most important data – namely, the state of an account – into the SafeBox. Any node can still independently compute and verify the cumulative Proof-of-Work required to construct the SafeBox.
The PascalCoin whitepaper elegantly highlights the unique historical independence that the SafeBox possesses:
“While there are approaches that cryptocurrencies could use such as pruning, warp-sync, "finality checkpoints", UTXO-snapshotting, etc, there is a fundamental difference with PascalCoin. Their new nodes can only prove they are on most-work-chain using the infinite history whereas in PascalCoin, new nodes can prove they are on the most-work chain without the infinite history.”
Some cryptocurrency old-timers might instinctively balk at the idea of full nodes eschewing the entire history for security, but such a reaction would showcase a lack of understanding on what the SafeBox really does.
A concrete example would go a long way to best illustrate what the SafeBox does. Let’s say I input the following operations in my calculator:
5 * 5 – 10 / 2 + 5
It does not take a genius to calculate the answer, 25. Now, the expression “5 \ 5 – 10 / 2 + 5”* would be forever imbued on a traditional blockchain’s history. But the SafeBox begs to differ. It says that the expression “5 \ 5 – 10 / 2 + 5”* should instead be simply “25” so as preserve simplicity, time, and space. In other words, the SafeBox simply preserves the account balance.
But some might still be unsatisfied and claim that if one cannot trace the series of operations (transactions) that lead to the final number (balance) of 25, the blockchain is inherently insecure.
Here are four important security aspects of the SafeBox that some people fail to realize:
(1) SafeBox Follows the Longest Chain of Proof-of-Work
The SafeBox mutates itself per 100 blocks. Each new SafeBox mutation must reference both to the previous SafeBox mutation and the preceding 100 blocks in order to be valid, and the resultant hash of the new mutated SafeBox must then be referenced by each of the new subsequent blocks, and the process repeats itself forever.
The fact that each new SafeBox mutation must reference to the previous SafeBox mutation is comparable to relying on the entire history. This is because the previous SafeBox mutation encapsulates the result of cumulative entire history except for the 100 blocks which is why each new SafeBox mutation requires both the previous SafeBox mutation and the preceding 100 blocks.
So in a sense, there is a single interconnected chain of inflows and outflows, supported by Byzantine Proof-of-Work consensus, instead of the entire history of transactions.
More concretely, the SafeBox follows the path of the longest chain of Proof-of-Work simply by design, and is thus cryptographically equivalent to the entire history even without tracing specific operations in the past. If the chain is rolled back with a 51% attack, only the attacker’s own account(s) in the SafeBox can be manipulated as is explained in the next part.
(2) A 51% Attack on PascalCoin Functions the Same as Others
A 51% attack on PascalCoin would work in a similar way as with other Proof-of-Work cryptocurrencies. An attacker cannot modify a transaction in the past without affecting the current SafeBox hash which is accepted by all honest nodes.
Someone might claim that if you roll back all the current blocks plus the 100 blocks prior to the SafeBox’s mutation, one could create a forged SafeBox with different balances for all accounts. This would be incorrect as one would be able to manipulate only his or her own account(s) in the SafeBox with a 51% attack – just as is the case with other UTXO cryptocurrencies. The SafeBox stores the balances of all accounts which are in turn irreversibly linked only to their respective owners’ private keys.
(3) One Could Preserve the Entire History of the PascalCoin Blockchain
No blockchain data in PascalCoin is ever deleted even in the presence of the SafeBox. Since the SafeBox is cryptographically equivalent to a full node with the entire history as explained above, PascalCoin full nodes are not expected to contain infinite history. But for whatever reason(s) one may have, one could still keep all the PascalCoin blockchain history as well along with the SafeBox as an option even though it would be redundant.
Without storing the entire history of the PascalCoin blockchain, you can still trace the specific operations of the 100 blocks prior to when the SafeBox absorbs and reflects the net result (a single balance for each account) from those 100 blocks. But if you’re interested in tracing operations over a longer period in the past – as redundant as that may be – you’d have the option to do so by storing the entire history of the PascalCoin blockchain.
(4) The SafeBox is Equivalent to the Entire Blockchain History
Some skeptics may ask this question: “What if the SafeBox is forever lost? How would you be able to verify your accounts?” Asking this question is tantamount to asking to what would happen to Bitcoin if all of its entire history was erased. The result would be chaos, of course, but the SafeBox is still in line with the general security model of a traditional blockchain with respect to black swans.
Now that we know the security of the SafeBox is not compromised, what are the implications of this new blockchain paradigm? A colorful illustration as follows still wouldn’t do justice to the subtle revolution that the SafeBox ushers. The automobiles we see on the street are the cookie-and-butter representation of traditional blockchain systems. The SafeBox, on the other hand, supercharges those traditional cars to become the Transformers from Michael Bay’s films.
The SafeBox is an entirely different blockchain architecture that is impressive in its simplicity and ingenuity. The SafeBox’s design is only the opening act for PascalCoin’s vast nuclear arsenal. If the above was all that PascalCoin offers, it still wouldn’t come close to achieving the unicorn status but luckily, we have just scratched the surface. Please keep on reading on if you want to learn how PascalCoin is going to shatter the cryptocurrency industry into pieces. Buckle down as this is going to be a long read as we explore further about the SafeBox’s implications.
Part #2: 0-Confirmation Transactions
To begin, 0-confirmation transactions are secure in PascalCoin thanks to the SafeBox.
The following paraphrases an explanation of PascalCoin’s 0-confirmations from the whitepaper:
“Since PascalCoin is not a UTXO-based currency but rather a State-based currency thanks to the SafeBox, the security guarantee of 0-confirmation transactions are much stronger than in UTXO-based currencies. For example, in Bitcoin if a merchant accepts a 0-confirmation transaction for a coffee, the buyer can simply roll that transaction back after receiving the coffee but before the transaction is confirmed in a block. The way the buyer does this is by re-spending those UTXOs to himself in a new transaction (with a higher fee) thus invalidating them for the merchant. In PascalCoin, this is virtually impossible since the buyer's transaction to the merchant is simply a delta-operation to debit/credit a quantity from/to accounts respectively. The buyer is unable to erase or pre-empt this two-sided, debit/credit-based transaction from the network’s pending pool until it either enters a block for confirmation or is discarded with respect to both sender and receiver ends. If the buyer tries to double-spend the coffee funds after receiving the coffee but before they clear, the double-spend transaction will not propagate the network since nodes cannot propagate a double-spending transaction thanks to the debit/credit nature of the transaction. A UTXO-based transaction is initially one-sided before confirmation and therefore is more exposed to one-sided malicious schemes of double spending.”
Phew, that explanation was technical but it had to be done. In summary, PascalCoin possesses the only secure 0-confirmation transactions in the cryptocurrency industry, and it goes without saying that this means PascalCoin is extremely fast. In fact, PascalCoin is capable of 72,000 TPS even prior to any additional extensive optimizations down the road. In other words, PascalCoin is as instant as it gets and gives Nano a run for its money.
Part #3: Zero Fee
Let’s circle back to our discussion of PascalCoin’s 0-confirmation capability. Here’s a little fun magical twist to PascalCoin’s 0-confirmation magic: 0-confirmation transactions are zero-fee. As in you don’t pay a single cent in fee for each 0-confirmation! There is just a tiny downside: if you create a second transaction in a 5-minute block window then you’d need to pay a minimal fee. Imagine using Nano but with a significantly stronger anti-DDOS protection for spam! But there shouldn’t be any complaint as this fee would amount to 0.0001 Pascal or $0.00002 based on the current price of a Pascal at the time of this writing.
So, how come the fee for blazingly fast transactions is nonexistent? This is where the magic of the SafeBox arises in three ways:
(1) PascalCoin possesses the secure 0-confirmation feature as discussed above that enables this speed.
(2) There is no fee bidding competition of transaction priority typical in UTXO cryptocurrencies since, once again, PascalCoin operates on secure 0-confirmations.
(3) There is no fee incentive needed to run full nodes on behalf of the network’s security beyond the consensus rewards.
Part #4: Blockchain Size
Let’s expand more on the third point above, using Ethereum as an example. Since Ethereum’s launch in 2015, its full blockchain size is currently around 2 TB, give or take, but let’s just say its blockchain size is 100 GB for now to avoid offending the Ethereum elitists who insist there are different types of full nodes that are lighter. Whoever runs Ethereum’s full nodes would expect storage fees on top of the typical consensus fees as it takes significant resources to shoulder Ethereum’s full blockchain size and in turn secure the network. What if I told you that PascalCoin’s full blockchain size will never exceed few GBs after thousands of years? That is just what the SafeBox enables PascalCoin to do so. It is estimated that by 2072, PascalCoin’s full nodes will only be 6 GB which is low enough not to warrant any fee incentives for hosting full nodes. Remember, the SafeBox is an ultra-light cryptographic data structure that is cryptographically equivalent to a blockchain with the entire transaction history. In other words, the SafeBox is a compact spreadsheet of all account balances that functions as PascalCoin’s full node!
Not only does the SafeBox’s infinitesimal memory size helps to reduce transaction fees by phasing out any storage fees, but it also paves the way for true decentralization. It would be trivial for every PascalCoin user to opt a full node in the form of a wallet. This is extreme decentralization at its finest since the majority of users of other cryptocurrencies ditch full nodes due to their burdensome sizes. It is naïve to believe that storage costs would reduce enough to the point where hosting full nodes are trivial. Take a look at the following chart outlining the trend of storage cost.

* https://www.backblaze.com/blog/hard-drive-cost-per-gigabyte/
As we can see, storage costs continue to decrease but the descent is slowing down as is the norm with technological improvements. In the meantime, blockchain sizes of other cryptocurrencies are increasing linearly or, in the case of smart contract engines like Ethereum, parabolically. Imagine a cryptocurrency smart contract engine like Ethereum garnering worldwide adoption; how do you think Ethereum’s size would look like in the far future based on the following chart?


https://i.redd.it/k57nimdjmo621.png

Ethereum’s future blockchain size is not looking pretty in terms of sustainable security. Sharding is not a fix for this issue since there still needs to be full nodes but that is a different topic for another time.
It is astonishing that the cryptocurrency community as a whole has passively accepted this forever-expanding-blockchain-size problem as an inescapable fate.
PascalCoin is the only cryptocurrency that has fully escaped the death vortex of forever expanding blockchain size. Its blockchain size wouldn’t exceed 10 GB even after many hundreds of years of worldwide adoption. Ethereum’s blockchain size after hundreds of years of worldwide adoption would make fine comedy.
Part #5: Simple, Short, and Ordinal Addresses
Remember how the SafeBox works by snapshotting all account balances? As it turns out, the account address system is almost as cool as the SafeBox itself.
Imagine yourself in this situation: on a very hot and sunny day, you’re wandering down the street across from your house and ran into a lemonade stand – the old-fashioned kind without any QR code or credit card terminal. The kid across you is selling a lemonade cup for 1 Pascal with a poster outlining the payment address as 5471-55. You flip out your phone and click “Send” with 1 Pascal to the address 5471-55; viola, exactly one second later you’re drinking your lemonade without paying a cent for the transaction fee!
The last thing one wants to do is to figure out how to copy/paste to, say, the following address 1BoatSLRHtKNngkdXEeobR76b53LETtpyT on the spot wouldn’t it? Gone are the obnoxiously long addresses that plague all cryptocurrencies. The days of those unreadable addresses will be long gone – it has to be if blockchain is to innovate itself for the general public. EOS has a similar feature for readable addresses but in a very limited manner in comparison, and nicknames attached to addresses in GUIs don’t count since blockchain-wide compatibility wouldn’t hold.
Not only does PascalCoin has the neat feature of having addresses (called PASAs) that amount to up to 6 or 7 digits, but PascalCoin can also incorporate in-protocol address naming as opposed to GUI address nicknames. Suppose I want to order something from Amazon using Pascal; I simply search the word “Amazon” then the corresponding account number shows up. Pretty neat, right?
The astute reader may gather that PascalCoin’s address system makes it necessary to commoditize addresses, and he/she would be correct. Some view this as a weakness; part #10 later in this segment addresses this incorrect perception.
Part #6: Privacy
As if the above wasn’t enough, here’s another secret that PascalCoin has: it is a full-blown privacy coin. It uses two separate foundations to achieve comprehensive anonymity: in-protocol mixer for transfer amounts and zn-SNARKs for private balances. The former has been implemented and the latter is on the roadmap. Both the 0-confirmation transaction and the negligible transaction fee would make PascalCoin the most scalable privacy coin of any other cryptocurrencies pending the zk-SNARKs implementation.
Part #7: Smart Contracts
Next, PascalCoin will take smart contracts to the next level with a layer-2 overlay consensus system that pioneers sidechains and other smart contract implementations.
In formal terms, this layer-2 architecture will facilitate the transfer of data between PASAs which in turn allows clean enveloping of layer-2 protocols inside layer-1 much in the same way that HTTP lives inside TCP.
To summarize:
· The layer-2 consensus method is separate from the layer-1 Proof-of-Work. This layer-2 consensus method is independent and flexible. A sidechain – based on a single encompassing PASA – could apply Proof-of-Stake (POS), Delegated Proof-of-Stake (DPOS), or Directed Acyclic Graph (DAG) as the consensus system of its choice.
· Such a layer-2 smart contract platform can be written in any languages.
· Layer-2 sidechains will also provide very strong anonymity since funds are all pooled and keys are not used to unlock them.
· This layer-2 architecture is ingenious in which the computation is separate from layer-2 consensus, in effect removing any bottleneck.
· Horizontal scaling exists in this paradigm as there is no interdependence between smart contracts and states are not managed by slow sidechains.
· Speed and scalability are fully independent of PascalCoin.
One would be able to run the entire global financial system on PascalCoin’s infinitely scalable smart contract platform and it would still scale infinitely. In fact, this layer-2 architecture would be exponentially faster than Ethereum even after its sharding is implemented.
All this is the main focus of PascalCoin’s upcoming version 5 in 2019. A whitepaper add-on for this major upgrade will be released in early 2019.
Part #8: RandomHash Algorithm
Surely there must be some tradeoffs to PascalCoin’s impressive capabilities, you might be asking yourself. One might bring up the fact that PascalCoin’s layer-1 is based on Proof-of-Work and is thus susceptible to mining centralization. This would be a fallacy as PascalCoin has pioneered the very first true ASIC, GPU, and dual-mining resistant algorithm known as RandomHash that obliterates anything that is not CPU based and gives all the power back to solo miners.
Here is the official description of RandomHash:
“RandomHash is a high-level cryptographic hash algorithm that combines other well-known hash primitives in a highly serial manner. The distinguishing feature is that calculations for a nonce are dependent on partial calculations of other nonces, selected at random. This allows a serial hasher (CPU) to re-use these partial calculations in subsequent mining saving 50% or more of the work-load. Parallel hashers (GPU) cannot benefit from this optimization since the optimal nonce-set cannot be pre-calculated as it is determined on-the-fly. As a result, parallel hashers (GPU) are required to perform the full workload for every nonce. Also, the algorithm results in 10x memory bloat for a parallel implementation. In addition to its serial nature, it is branch-heavy and recursive making in optimal for CPU-only mining.”
One might be understandably skeptical of any Proof-of-Work algorithm that solves ASIC and GPU centralization once for all because there have been countless proposals being thrown around for various algorithms since the dawn of Bitcoin. Is RandomHash truly the ASIC & GPU killer that it claims to be?
Herman Schoenfeld, the inventor behind RandomHash, described his algorithm in the following:
“RandomHash offers endless ASIC-design breaking surface due to its use of recursion, hash algo selection, memory hardness and random number generation.
For example, changing how round hash selection is made and/or random number generator algo and/or checksum algo and/or their sequencing will totally break an ASIC design. Conceptually if you can significantly change the structure of the output assembly whilst keeping the high-level algorithm as invariant as possible, the ASIC design will necessarily require proportional restructuring. This results from the fact that ASIC designs mirror the ASM of the algorithm rather than the algorithm itself.”
Polyminer1 (pseudonym), one of the members of the PascalCoin core team who developed RHMiner (official software for mining RandomHash), claimed as follows:
“The design of RandomHash is, to my experience, a genuine innovation. I’ve been 30 years in the field. I’ve rarely been surprised by anything. RandomHash was one of my rare surprises. It’s elegant, simple, and achieves resistance in all fronts.”
PascalCoin may have been the first party to achieve the race of what could possibly be described as the “God algorithm” for Proof-of-Work cryptocurrencies. Look no further than one of Monero’s core developers since 2015, Howard Chu. In September 2018, Howard declared that he has found a solution, called RandomJS, to permanently keep ASICs off the network without repetitive algorithm changes. This solution actually closely mirrors RandomHash’s algorithm. Discussing about his algorithm, Howard asserted that “RandomJS is coming at the problem from a direction that nobody else is.”
Link to Howard Chu’s article on RandomJS:
https://www.coindesk.com/one-musicians-creative-solution-to-drive-asics-off-monero
Yet when Herman was asked about Howard’s approach, he responded:
“Yes, looks like it may work although using Javascript was a bit much. They should’ve just used an assembly subset and generated random ASM programs. In a way, RandomHash does this with its repeated use of random mem-transforms during expansion phase.”
In the end, PascalCoin may have successfully implemented the most revolutionary Proof-of-Work algorithm, one that eclipses Howard’s burgeoning vision, to date that almost nobody knows about. To learn more about RandomHash, refer to the following resources:
RandomHash whitepaper:
https://www.pascalcoin.org/storage/whitepapers/RandomHash_Whitepaper.pdf
Technical proposal for RandomHash:
https://github.com/PascalCoin/PascalCoin/blob/mastePIP/PIP-0009.md
Someone might claim that PascalCoin still suffers from mining centralization after RandomHash, and this is somewhat misleading as will be explained in part #10.
Part #9: Fair Distribution and Governance
Not only does PascalCoin rest on superior technology, but it also has its roots in the correct philosophy of decentralized distribution and governance. There was no ICO or pre-mine, and the developer fund exists as a percentage of mining rewards as voted by the community. This developer fund is 100% governed by a decentralized autonomous organization – currently facilitated by the PascalCoin Foundation – that will eventually be transformed into an autonomous smart contract platform. Not only is the developer fund voted upon by the community, but PascalCoin’s development roadmap is also voted upon the community via the Protocol Improvement Proposals (PIPs).
This decentralized governance also serves an important benefit as a powerful deterrent to unseemly fork wars that befall many cryptocurrencies.
Part #10: Common Misconceptions of PascalCoin
“The branding is terrible”
PascalCoin is currently working very hard on its image and is preparing for several branding and marketing initiatives in the short term. For example, two of the core developers of the PascalCoin recently interviewed with the Fox Business Network. A YouTube replay of this interview will be heavily promoted.
Some people object to the name PascalCoin. First, it’s worth noting that PascalCoin is the name of the project while Pascal is the name of the underlying currency. Secondly, Google and YouTube received excessive criticisms back then in the beginning with their name choices. Look at where those companies are nowadays – surely a somewhat similar situation faces PascalCoin until the name’s familiarity percolates into the public.
“The wallet GUI is terrible”
As the team is run by a small yet extremely dedicated developers, multiple priorities can be challenging to juggle. The lack of funding through an ICO or a pre-mine also makes it challenging to accelerate development. The top priority of the core developers is to continue developing full-time on the groundbreaking technology that PascalCoin offers. In the meantime, an updated and user-friendly wallet GUI has been worked upon for some time and will be released in due time. Rome wasn’t built in one day.
“One would need to purchase a PASA in the first place”
This is a complicated topic since PASAs need to be commoditized by the SafeBox’s design, meaning that PASAs cannot be obtained at no charge to prevent systematic abuse. This raises two seemingly valid concerns:
· As a chicken and egg problem, how would one purchase a PASA using Pascal in the first place if one cannot obtain Pascal without a PASA?
· How would the price of PASAs stay low and affordable in the face of significant demand?
With regards to the chicken and egg problem, there are many ways – some finished and some unfinished – to obtain your first PASA as explained on the “Get Started” page on the PascalCoin website:
https://www.pascalcoin.org/get_started
More importantly, however, is the fact that there are few methods that can get your first PASA for free. The team will also release another method soon in which you could obtain your first PASA for free via a single SMS message. This would probably become by far the simplest and the easiest way to obtain your first PASA for free. There will be more new ways to easily obtain your first PASA for free down the road.
What about ensuring the PASA market at large remains inexpensive and affordable following your first (and probably free) PASA acquisition? This would be achieved in two ways:
· Decentralized governance of the PASA economics per the explanation in the FAQ section on the bottom of the PascalCoin website (https://www.pascalcoin.org/)
· Unlimited and free pseudo-PASAs based on layer-2 in the next version release.
“PascalCoin is still centralized after the release of RandomHash”
Did the implementation of RandomHash from version 4 live up to its promise?
The official goals of RandomHash were as follow:
(1) Implement a GPU & ASIC resistant hash algorithm
(2) Eliminate dual mining
The two goals above were achieved by every possible measure.
Yet a mining pool, Nanopool, was able to regain its hash majority after a significant but a temporary dip.
The official conclusion is that, from a probabilistic viewpoint, solo miners are more profitable than pool miners. However, pool mining is enticing for solo miners who 1) have limited hardware as it ensures a steady income instead of highly profitable but probabilistic income via solo mining, and 2) who prefer convenient software and/or GUI.
What is the next step, then? While the barrier of entry for solo miners has successfully been put down, additional work needs to be done. The PascalCoin team and the community are earnestly investigating additional steps to improve mining decentralization with respect to pool mining specifically to add on top of RandomHash’s successful elimination of GPU, ASIC, and dual-mining dominance.
It is likely that the PascalCoin community will promote the following two initiatives in the near future:
(1) Establish a community-driven, nonprofit mining pool with attractive incentives.
(2) Optimize RHMiner, PascalCoin’s official solo mining software, for performance upgrades.
A single pool dominance is likely short lived once more options emerge for individual CPU miners who want to avoid solo mining for whatever reason(s).
Let us use Bitcoin as an example. Bitcoin mining is dominated by ASICs and mining pools but no single pool is – at the time of this writing – even close on obtaining the hash majority. With CPU solo mining being a feasible option in conjunction with ASIC and GPU mining eradication with RandomHash, the future hash rate distribution of PascalCoin would be far more promising than Bitcoin’s hash rate distribution.
PascalCoin is the Unicorn Cryptocurrency
If you’ve read this far, let’s cut straight to the point: PascalCoin IS the unicorn cryptocurrency.
It is worth noting that PascalCoin is still a young cryptocurrency as it was launched at the end of 2016. This means that many features are still work in progress such as zn-SNARKs, smart contracts, and pool decentralization to name few. However, it appears that all of the unicorn criteria are within PascalCoin’s reach once PascalCoin’s technical roadmap is mostly completed.
Based on this expository on PascalCoin’s technology, there is every reason to believe that PascalCoin is the unicorn cryptocurrency. PascalCoin also solves two fundamental blockchain problems beyond the unicorn criteria that were previously considered unsolvable: blockchain size and simple address system. The SafeBox pushes PascalCoin to the forefront of cryptocurrency zeitgeist since it is a superior solution compared to UTXO, Directed Acyclic Graph (DAG), Block Lattice, Tangle, and any other blockchain innovations.

An extensive guide for cashing out bitcoin and cryptocurrencies into private banks

Hey guys.
Merry Xmas !
I am coming back to you with a follow up post, as I have helped many people cash out this year and I have streamlined the process. After my original post, I received many requests to be more specific and provide more details. I thought that after the amazing rally we have been attending over the last few months, and the volatility of the last few days, it would be interesting to revisit more extensively.
The attitude of banks around crypto is changing slowly, but it is still a tough stance. For the first partial cash out I operated around a year ago for a client, it took me months to find a bank. They wouldn’t want to even consider the case and we had to knock at each and every door. Despite all my contacts it was very difficult back in the days. This has changed now, and banks have started to open their doors, but there is a process, a set of best practices and codes one has to follow.
I often get requests from crypto guys who are very privacy-oriented, and it takes me months to have them understand that I am bound by Swiss law on banking secrecy, and I am their ally in this onboarding process. It’s funny how I have to convince people that banks are legit, while on the other side, banks ask me to show that crypto millionaires are legit. I have a solid background in both banking and in crypto so I manage to make the bridge, but yeah sometimes it is tough to reconcile the two worlds. I am a crypto enthusiast myself and I can say that after years of work in the banking industry I have grown disillusioned towards banks as well, like many of you. Still an account in a Private bank is convenient and powerful. So let’s get started.
There are two different aspects to your onboarding in a Swiss Private bank, compliance-wise.
*The origin of your crypto wealth
*Your background (residence, citizenship and probity)
These two aspects must be documented in-depth.
How to document your crypto wealth. Each new crypto millionaire has a different story. I may detail a few fun stories later in this post, but at the end of the day, most of crypto rich I have met can be categorized within the following profiles: the miner, the early adopter, the trader, the corporate entity, the black market, the libertarian/OTC buyer. The real question is how you prove your wealth is legit.
1. Context around the original amount/investment Generally speaking, your first crypto purchase may not be documented. But the context around this acquisition can be. I have had many cases where the original amount was bought through Mtgox, and no proof of purchase could be provided, nor could be documented any Mtgox claim. That’s perfectly fine. At some point Mtgox amounted 70% of the bitcoin transactions globally, and people who bought there and managed to withdraw and keep hold of their bitcoins do not have any Mtgox claim. This is absolutely fine. However, if you can show me the record of a wire from your bank to Tisbane (Mtgox's parent company) it's a great way to start.
Otherwise, what I am trying to document here is the following: I need context. If you made your first purchase by saving from summer jobs, show me a payroll. Even if it was USD 2k. If you acquired your first bitcoins from mining, show me the bills of your mining equipment from 2012 or if it was through a pool mine, give me your slushpool account ref for instance. If you were given bitcoin against a service you charged, show me an invoice.
2. Tracking your wealth until today and making sense of it. What I have been doing over the last few months was basically educating compliance officers. Thanks God, the blockchain is a global digital ledger! I have been telling my auditors and compliance officers they have the best tool at their disposal to lead a proper investigation. Whether you like it or not, your wealth can be tracked, from address to address. You may have thought all along this was a bad feature, but I am telling you, if you want to cash out, in the context of Private Banking onboarding, tracking your wealth through the block explorer is a boon. We can see the inflows, outflows. We can see the age behind an address. An early adopter who bought 1000 BTC in 2010, and let his bitcoin behind one address and held thus far is legit, whether or not he has a proof of purchase to show. That’s just common sense. My job is to explain that to the banks in a language they understand.
Let’s have a look at a few examples and how to document the few profiles I mentioned earlier.
The trader. I love traders. These are easy cases. I have a ton of respect for them. Being a trader myself in investment banks for a decade earlier in my career has taught me that controlling one’s emotions and having the discipline to impose oneself some proper risk management system is really really hard. Further, being able to avoid the exchange bankruptcy and hacks throughout crypto history is outstanding. It shows real survival instinct, or just plain blissed ignorance. In any cases traders at exchange are easy cases to corroborate since their whole track record is potentially available. Some traders I have met have automated their trading and have shown me more than 500k trades done over the span of 4 years. Obviously in this kind of scenario I don’t show everything to the bank to avoid information overload, and prefer to do some snacking here and there. My strategy is to show the early trades, the most profitable ones, explain the trading strategy and (partially expose) the situation as of now with id pages of the exchanges and current balance. Many traders have become insensitive to the risk of parking their crypto at exchange as they want to be able to trade or to grasp an occasion any minute, so they generally do not secure a substantial portion on the blockchain which tends to make me very nervous.
The early adopter. Provided that he has not mixed his coin, the early adopter or “hodler” is not a difficult case either. Who cares how you bought your first 10k btc if you bought them below 3$ ? Even if you do not have a purchase proof, I would generally manage to find ways. We just have to corroborate the original 30’000 USD investment in this case. I mainly focus on three things here:
*proof of early adoption I have managed to educate some banks on a few evidences specifically related to crypto markets. For instance with me, an old bitcointalk account can serve as a proof of early adoption. Even an old reddit post from a few years ago where you say how much you despise this Ripple premined scam can prove to be a treasure readily available to show you were early.
*story telling Compliance officers like to know when, why and how. They are human being looking for simple answers to simple questions and they don’t want like to be played fool. Telling the truth, even without a proof can do wonders, and even though bluffing might still work because banks don’t fully understand bitcoin yet, it is a risky strategy that is less and less likely to pay off as they are getting more sophisticated by the day.
*micro transaction from an old address you control This is the killer feature. Send a $20 worth transaction from an old address to my company wallet and to one of my partner bank’s wallet and you are all set ! This is gold and considered a very solid piece of evidence. You can also do a microtransaction to your own wallet, but banks generally prefer transfer to their own wallet. Patience with them please. they are still learning.
*signature message Why do a micro transaction when you can sign a message and avoid potentially tainting your coins ?
*ICO millionaire Some clients made their wealth participating in ETH crowdsale or IOTA ICO. They were very easy to deal with obviously and the account opening was very smooth since we could evidence the GENESIS TxHash flow.
The miner Not so easy to proof the wealth is legit in that case. Most early miners never took screenshot of the blocks on bitcoin core, nor did they note down the block number of each block they mined. Until the the Slashdot article from August 2010 anyone could mine on his laptop, let his computer run overnight and wake up to a freshly minted block containing 50 bitcoins back in the days. Not many people were structured enough to store and secure these coins, avoid malwares while syncing the blockchain continuously, let alone document the mined blocks in the process. What was 50 BTC worth really for the early miners ? dust of dollars, games and magic cards… Even miners post 2010 are generally difficult to deal with in terms of compliance onboarding. Many pool mining are long dead. Deepbit is down for instance and the founders are MIA. So my strategy to proof mining activity is as follow:
*Focusing on IT background whenever possible. An IT background does help a lot to bring some substance to the fact you had the technical ability to operate a mining rig.
*Showing mining equipment receipts. If you mined on your own you must have bought the hardware to do so. For instance mining equipment receipts from butterfly lab from 2012-2013 could help document your case. Similarly, high electricity bill from your household on a consistent basis back in the day could help. I have already unlocked a tricky case in the past with such documents when the bank was doubtful.
*Wallet.dat files with block mining transactions from 2011 thereafter This obviously is a fantastic piece of evidence for both you and me if you have an old wallet and if you control an address that received original mined blocks, (even if the wallet is now empty). I will make sure compliance officers understand what it means, and as for the early adopter, you can prove your control over these wallet through a microtransaction. With these kind of addresses, I can show on the block explorer the mined block rewards hitting at regular time interval, and I can even spot when difficulty level increased or when halvening process happened.
*Poolmining account. Here again I have educated my partner bank to understand that a slush account opened in 2013 or an OnionTip presence was enough to corroborate mining activity. The block explorer then helps me to do the bridge with your current wallet.
*Describing your set up and putting it in context In the history of mining we had CPU, GPU, FPG and ASICs mining. I will describe your technical set up and explain why and how your set up was competitive at that time.
The corporate entity Remember 2012 when we were all convinced bitcoin would take over the world, and soon everyone would pay his coffee in bitcoin? How naïve we were to think transaction fees would remain low forever. I don’t blame bitcoin cash supporters; I once shared this dream as well. Remember when we thought global adoption was right around the corner and some brick and mortar would soon accept bitcoin transaction as a common mean of payment? Well, some shop actually did accept payment and held. I had a few cases as such of shops holders, who made it to the multi million mark holding and had invoices or receipts to proof the transactions. If you are organized enough to keep a record for these trades and are willing to cooperate for the documentation, you are making your life easy. The digital advertising business is also a big market for the bitcoin industry, and affiliates partner compensated in btc are common. It is good to show an invoice, it is better to show a contract. If you do not have a contract (which is common since all advertising deals are about ticking a check box on the website to accept terms and conditions), there are ways around that. If you are in that case, pm me.
The black market Sorry guys, I can’t do much for you officially. Not that I am judging you. I am a libertarian myself. It’s just already very difficult to onboard legit btc adopters, so the black market is a market I cannot afford to consider. My company is regulated so KYC and compliance are key for me if I want to stay in business. Behind each case I push forward I am risking the credibility and reputation I have built over the years. So I am sorry guys I am not risking it to make an extra buck. Your best hope is that crypto will eventually take over the world and you won’t need to cash out anyway. Or go find a Lithuanian bank that is light on compliance and cooperative.
The OTC buyer and the libertarian. Generally a very difficult case. If you bought your stack during your journey in Japan 5 years ago to a guy you never met again; or if you accumulated on https://localbitcoins.com/ and kept no record or lost your account, it is going to be difficult. Not impossible but difficult. We will try to build a case with everything else we have, and I may be able to onboard you. However I am risking a lot here so I need to be 100% confident you are legit, before I defend you. Come & see me in Geneva, and we will talk. I will run forensic services like elliptic, chainalysis, or scorechain on an extract of your wallet. If this scan does not raise too many red flags, then maybe we can work together ! If you mixed your coins all along your crypto history, and shredded your seeds because you were paranoid, or if you made your wealth mining professionally monero over the last 3 years but never opened an account at an exchange. ¯_(ツ)_/¯ I am not a magician and don’t get me wrong, I love monero, it’s not the point.
Cashing out ICOs Private companies or foundations who have ran an ICO generally have a very hard time opening a bank account. The few banks that accept such projects would generally look at 4 criteria:
*Seriousness of the project Extensive study of the whitepaper to limit the reputation risk
*AML of the onboarding process ICOs 1.0 have no chance basically if a background check of the investors has not been conducted
*Structure of the moral entity List of signatories, certificate of incumbency, work contract, premises...
*Fiscal conformity Did the company informed the authorities and seek a fiscal ruling.
For the record, I am not into the tax avoidance business, so people come to me with a set up and I see if I can make it work within the legal framework imposed to me.
First, stop thinking Switzerland is a “offshore heaven” Swiss banks have made deals with many governments for the exchange of fiscal information. If you are a French citizen, resident in France and want to open an account in a Private Bank in Switzerland to cash out your bitcoins, you will get slaughtered (>60%). There are ways around that, and I could refer you to good tax specialists for fiscal optimization, but I cannot organize it myself. It would be illegal for me. Swiss private banks makes it easy for you to keep a good your relation with your retail bank and continue paying your bills without headaches. They are integrated to SEPA, provide ebanking and credit cards.
For information, these are the kind of set up some of my clients came up with. It’s all legal; obviously I do not onboard clients that are not tax compliant. Further disclaimer: I did not contribute myself to these set up. Do not ask me to organize it for you. I won’t.
EU tricks
Swiss lump sum taxation Foreign nationals resident in Switzerland can be taxed on a lump-sum basis if they are not gainfully employed in our country. Under the lump-sum tax regime, foreign nationals taking residence in Switzerland may choose to pay an expense-based tax instead of ordinary income and wealth tax. Attractive cantons for the lump sum taxation are Zug, Vaud, Valais, Grisons, Lucerne and Berne. To make it short, you will be paying somewhere between 200 and 400k a year and all expenses will be deductible.
Switzerland has adopted a very friendly attitude towards crypto currency in general. There is a whole crypto valley in Zug now. 30% of ICOs are operated in Switzerland. The reason is that Switzerland has thrived for centuries on banking secrecy, and today with FATCA and exchange of fiscal info with EU, banking secrecy is dead. Regulators in Switzerland have understood that digital ledger technologies were a way to roll over this competitive advantage for the generations to come. Switzerland does not tax capital gains on crypto profits. The Finma has a very pragmatic approach. They have issued guidance- updated guidelines here. They let the business get organized and operate their analysis on a case per case basis. Only after getting a deep understanding of the market will they issue a global fintech license in 2019. This approach is much more realistic than legislations which try to regulate everything beforehand.
Italy new tax exemption. It’s a brand new fiscal exemption. Go to Aoste, get residency and you could be taxed a 100k/year for 10years. Yes, really.
Portugal What’s crazy in Europe is the lack of fiscal harmonization. Even if no one in Brussels dares admit it, every other country is doing fiscal dumping. Portugal is such a country and has proved very friendly fiscally speaking. I personally have a hard time trusting Europe. I have witnessed what happened in Greece over the last few years. Some of our ultra high net worth clients got stuck with capital controls. I mean no way you got out of crypto to have your funds confiscated at the next financial crisis! Anyway. FYI
Malta Generally speaking, if you get a residence somewhere you have to live there for a certain period of time. Being stuck in Italy is no big deal with Schengen Agreement, but in Malta it is a different story. In Malta, the ordinary residence scheme is more attractive than the HNWI residence scheme. Being an individual, you can hold a residence permit under this scheme and pay zero income tax in Malta in a completely legal way.
Monaco Not suitable for French citizens, but for other Ultra High Net worth individual, Monaco is worth considering. You need an account at a local bank as a proof of fortune, and this account generally has to be seeded with at least EUR500k. You also need a proof of residence. I do mean UHNI because if you don’t cash out minimum 30m it’s not interesting. Everything is expensive in Monaco. Real Estate is EUR 50k per square meter. A breakfast at Monte Carlo Bay hotel is 70 EUR. Monaco is sunny but sometimes it feels like a golden jail. Do you really want that for your kids?
Dubaï
  1. Set up a company in Dubaï, get your resident card.
  2. Spend one day every 6 month there
  3. ???
  4. Be tax free
US tricks Some Private banks in Geneva do have the license to manage the assets of US persons and U.S citizens. However, do not think it is a way to avoid paying taxes in the US. Opening an account at an authorized Swiss Private banks is literally the same tax-wise as opening an account at Fidelity or at Bank of America in the US. The only difference is that you will avoid all the horror stories. Horror stories are all real by the way. In Switzerland, if you build a decent case and answer all the questions and corroborate your case in depth, you will manage to convince compliance officers beforehand. When the money eventually hits your account, it is actually available and not frozen.
The IRS and FATCA require to file FBAR if an offshore account is open. However FBAR is a reporting requirement and does not have taxes related to holding an account outside the US. The taxes would be the same if the account was in the US. However penalties for non compliance with FBAR are very large. The tax liability management is actually performed through the management of the assets ( for exemple by maximizing long term capital gains and minimizing short term gains).
The case for Porto Rico. Full disclaimer here. I am not encouraging this. Have not collaborated on such tax avoidance schemes. if you are interested I strongly encourage you to seek a tax advisor and get a legal opinion. I am not responsible for anything written below. I am not going to say much because I am so afraid of uncle Sam that I prefer to humbly pass the hot potato to pwc From here all it takes is a good advisor and some creativity to be tax free on your crypto wealth if you are a US person apparently. Please, please please don’t ask me more. And read the disclaimer again.
Trust tricks Generally speaking I do not accept fringe fiscal situation because it puts me in a difficult situation to the banks I work with, and it is already difficult enough to defend a legit crypto case. Trust might be a way to optimize your fiscal situation. Belize. Bahamas. Seychelles. Panama, You name it. At the end of the day, what matters for Swiss Banks are the beneficial owner and the settlor. Get a legal opinion, get it done, and when you eventually knock at a private bank’s door, don’t say it was for fiscal avoidance you stupid ! You will get the door smashed upon you. Be smarter. It will work. My advice is just to have it done by a great tax specialist lawyer, even if it costs you some money, as the entity itself needs to be structured in a professional way. Remember that with trust you are dispossessing yourself off your wealth. Not something to be taken lightly.
“Anonymous” cash out. Right. I think I am not going into this topic, neither expose the ways to get it done. Pm me for details. I already feel a bit uncomfortable with all the info I have provided. I am just going to mention many people fear that crypto exchange might become reporting entities soon, and rightly so. This might happen anyday. You have been warned. FYI, this only works for non-US and large cash out.
The difference between traders an investors. Danmark, Holland and Germany all make a huge difference if you are a passive investor or if you are a trader. ICO is considered investing for instance and is not taxed, while trading might be considered as income and charged aggressively. I would try my best to protect you and put a focus on your investor profile whenever possible, so you don't have to pay 52% tax if you do not have to :D
Full cash out or partial cash out? People who have been sitting on crypto for long have grown an emotional and irrational link with their coins. They come to me and say, look, I have 50m in crypto but I would like to cash out 500k only. So first let me tell you that as a wealth manager my advice to you is to take some off the table. Doing a partial cash out is absolutely fine. The market is bullish. We are witnessing a redistribution of wealth at a global scale. Bitcoin is the real #occupywallstreet, and every one will discuss crypto at Xmas eve which will make the market even more supportive beginning 2018, especially with all hedge funds entering the scene. If you want to stay exposed to bitcoin and altcoins, and believe these techs will change the world, it’s just natural you want to keep some coins. In the meantime, if you have lived off pizzas over the last years, and have the means to now buy yourself an nice house and have an account at a private bank, then f***ing do it mate ! Buy physical gold with this account, buy real estate, have some cash at hands. Even though US dollar is worthless to your eyes, it’s good and convenient to have some. Also remember your wife deserves it ! And if you have no wife yet and you are socially awkward like the rest of us, then maybe cashing out partially will help your situation ;)
What the Private Banks expect. Joke aside, it is important you understand something. If you come around in Zurich to open a bank account and partially cash out, just don’t expect Private Banks will make an exception for you if you are small. You can’t ask them to facilitate your cash out, buy a 1m apartment with the proceeds of the sale, and not leave anything on your current account. It won’t work. Sadly, under 5m you are considered small in private banking. The bank is ok to let you open an account, provided that your kyc and compliance file are validated, but they will also want you to become a client and leave some money there to invest. This might me despicable, but I am just explaining you their rules. If you want to cash out, you should sell enough to be comfortable and have some left. Also expect the account opening to last at least 3-4 week if everything goes well. You can't just open an account overnight.
The cash out logistics. Cashing out 1m USD a day in bitcoin or more is not so hard.
Let me just tell you this: Even if you get a Tier 4 account with Kraken and ask Alejandro there to raise your limit over $100k per day, Even if you have a bitfinex account and you are willing to expose your wealth there, Even if you have managed to pass all the crazy due diligence at Bitstamp,
The amount should be fractioned to avoid risking your full wealth on exchange and getting slaughtered on the price by trading big quantities. Cashing out involves significant risks at all time. There is a security risk of compromising your keys, a counterparty risk, a fat finger risk. Let it be done by professionals. It is worth every single penny.
Most importantly, there is a major difference between trading on an exchange and trading OTC. Even though it’s not publicly disclosed some exchange like Kraken do have OTC desks. Trading on an exchange for a large amount will weight on the prices. Bitcoin is a thin market. In my opinion over 30% of the coins are lost in translation forever. Selling $10m on an exchange in a day can weight on the prices more than you’d think. And if you trade on a exchange, everything is shown on record, and you might wipe out the prices because on exchanges like bitstamp or kraken ultimately your counterparties are retail investors and the market depth is not huge. It is a bit better on Bitfinex. It is way better to trade OTC. Accessing the institutional OTC market is not easy, and that is also the reason why you should ask a regulated financial intermediary if we are talking about huge amounts.
Last point, always chose EUR as opposed to USD. EU correspondent banks won’t generally block institutional amounts. However we had the cases of USD funds frozen or delayed by weeks.
Most well-known OTC desks are Cumberlandmining (ask for Lucas), Genesis (ask for Martin), Bitcoin Suisse AG (ask for Niklas), circletrade, B2C2, or Altcoinomy (ask for Olivier)
Very very large whales can also set up escrow accounts for massive block trades. This world, where blocks over 30k BTC are exchanged between 2 parties would deserve a reddit thread of its own. Crazyness all around.
Your options: DIY or going through a regulated financial intermediary.
Execution trading is a job in itself. You have to be patient, be careful not to wipe out the order book and place limit orders, monitor the market intraday for spikes or opportunities. At big levels, for a large cash out that may take weeks, these kind of details will save you hundred thousands of dollars. I understand crypto holders are suspicious and may prefer to do it by themselves, but there are regulated entities who now offer the services. Besides, being a crypto millionaire is not a guarantee you will get institutional daily withdrawal limits at exchange. You might, but it will take you another round of KYC with them, and surprisingly this round might be even more aggressive that the ones at Private banks since exchange have gone under intense scrutiny by regulators lately.
The fees for cashing out through a regulated financial intermediary to help you with your cash out should be around 1-2% flat on the nominal, not more. And for this price you should get the full package: execution/monitoring of the trades AND onboarding in a private bank. If you are asked more, you are being abused.
Of course, you also have the option to do it yourself. It is a way more tedious and risky process. Compliance with the exchange, compliance with the private bank, trading BTC/fiat, monitoring the transfers…You will save some money but it will take you some time and stress. Further, if you approach a private bank directly, it will trigger a series of red flag to the banks. As I said in my previous post, they call a direct approach a “walk-in”. They will be more suspicious than if you were introduced by someone and won’t hesitate to show you high fees and load your portfolio with in-house products that earn more money to the banks than to you. Remember also most banks still do not understand crypto so you will have a lot of explanations to provide and you will have to start form scratch with them!
The paradox of crypto millionaires Most of my clients who made their wealth through crypto all took massive amount of risks to end up where they are. However, most of them want their bank account to be managed with a low volatility fixed income capital preservation risk profile. This is a paradox I have a hard time to explain and I think it is mainly due to the fact that most are distrustful towards banks and financial markets in general. Many clients who have sold their crypto also have a cash-out blues in the first few months. This is a classic situation. The emotions involved in hodling for so long, the relief that everything has eventually gone well, the life-changing dynamics, the difficulties to find a new motivation in life…All these elements may trigger a post cash-out depression. It is another paradox of the crypto rich who has every card in his hand to be happy, but often feel a bit sad and lonely. Sometimes, even though it’s not my job, I had to do some psychological support. A lot of clients have also become my friends, because we have the same age and went through the same “ordeal”. First world problem I know… Remember, cashing out is not the end. It’s actually the beginning. Don’t look back, don’t regret. Cash out partially, because it does not make sense to cash out in full, regret it and want back in. relax.
The race to cash out crypto billionaire and the concept of late exiter. The Winklevoss brothers are obviously the first of a series. There will be crypto billionaires. Many of them. At a certain level you can have a whole family office working for you to manage your assets and take care of your needs . However, let me tell you it’s is not because you made it so big that you should think you are a genius and know everything better than anyone. You should hire professionals to help you. Managing assets require some education around the investment vehicles and risk management strategies. Sorry guys but with all the respect I have for wallstreebet, AMD and YOLO stock picking, some discipline is necessary. The investors who have made money through crypto are generally early adopters. However I have started to see another profile popping up. They are not early adopters. They are late exiters. It is another way but just as efficient. Last week I met the first crypto millionaire I know who first bough bitcoin over 1000$. 55k invested at the beginning of this year. Late adopter & late exiter is a route that can lead to the million.
Last remarks. I know banks, bankers, and FIAT currencies are so last century. I know some of you despise them and would like to have them burn to the ground. With compliance officers taking over the business, I would like to start the fire myself sometimes. I hope this extensive guide has helped some of you. I am around if you need more details. I love my job despite all my frustration towards the banking industry because it makes me meet interesting people on a daily basis. I am a crypto enthusiast myself, and I do think this tech is here to stay and will change the world. Banks will have to adapt big time. Things have started to change already; they understand the threat is real. I can feel the generational gap in Geneva, with all these old bankers who don’t get what’s going on. They glaze at the bitcoin chart on CNBC in disbelief and they start to get it. This bitcoin thing is not a joke. Deep inside, as an early adopter who also intends to be a late exiter, as a libertarian myself, it makes me smile with satisfaction.

The chatlog from #lightning-network discussing recent Lightning DDOS/vulnerability

bitPico [5:49 PM] If any LN testers see their connection slots full it’s us. We will release the attack code when ready. The network needs better protection against DDoS’s. (edited)
Laolu Osuntokun [5:59 PM] ? or report to specific implementations @bitPico? like the early days of bitcoin, don't think many impls have even started to start to cover dos vectors busy working on safety in other aspects
bitPico [6:00 PM] As it stands no implementation can handle connection exhaustion attacks by overflowing the underlying TCP stack.
Laolu Osuntokun [6:00 PM] not sure if any limit inbound connections yet
bitPico [6:02 PM] Doesn’t matter; we use the TCP half-open attack. This occurs at the kernel.
Laolu Osuntokun [6:02 PM] sure you'd still run into fd limits so that's not really impl specific
bitPico [6:02 PM] Yes; we exhaust the FD’s. (edited)
Laolu Osuntokun [6:04 PM] you could do the same for any active bitcoin node today, nodes would need to set up network-level mitigations unless the impls were super low level enough to detect something like that so would really depend on their default kernel settings
Matt Drollette [6:10 PM] echo 1 > /proc/sys/net/ipv4/tcp_syncookies … ?
bitPico [6:14 PM] Our Bitcoin implementation performs round-robin disconnects to induce network churn. This is one of the best methods to prevent most TCP attacks. Churn is needed in decentralized systems. It keeps them robust. Longstanding TCP connections are bad. *ie we disconnect N nodes every T mins.
Laolu Osuntokun [6:18 PM] if it's half open, how are you detecting the TCP connections then @bitPico? well for LN the connections are typically long lived @mdrollette yeh, defenses are at the kernel lvl
bitPico [6:21 PM] Round-robin disconnects free the kernel FD’s. There is also App level half-connect Works like this Syn Ack But don’t sent the Ack The connection is then half-open TCP connect scans work like this. TCP half-open scans are harder to detect.
ɹɑd [6:33 PM] Is there a way to tell lnd to listen on ipv4 instead of ipv6? When I try lnd --listen=0.0.0.0:9735 ..., it is listening on IPv6 TCP *:9735 but I need it to listen on IPv4.
Matt Drollette [6:34 PM] I think if you give it a specific IP instead of 0.0.0.0 it will only bind to that specific interface
ɹɑd [6:34 PM] ok, trying that…
bitPico [6:36 PM] Dual-stack OS will still open IPv6 Windows and Linux are VERY different TCP stacks. The behaviour is different.
ɹɑd [6:38 PM] Nice, that worked. Thanks, @mdrollette
bitPico [7:13 PM] How does LN protect from “dead end packets”? ie* onion wrapped but final destination doesn’t exist. aka routing amplification attack
kekalot [7:14 PM] :trumpet::skull:
bitPico [7:16 PM] We will test it and perform a 100,000 route amplification. We are trying to make our test kit reusable as possible to work out the kinks. (edited)
kekalot [7:16 PM] :trumpet::skull:
bitPico [7:25 PM] Seeing bad OP-SEC on LN; don’t name your node as the type of hardware. Those raspberry pi’s will go down.
kekalot [7:25 PM] :trumpet: :skull:
camelCase [7:26 PM] :joy:

bitPico [9:00 PM] We are most interested in our “route payload amplification” attack vector. This attack onion wraps payloads via hop by hop where the last hop is the first hop creating a self-denial of service where the LN nodes attack themselves after long route traversal. Exploiting the anonymous nature of onion routing allows no defense to the network. Anonymous routing in and of itself creates a situation where the network can get into an endless loop of self DDoS. Once we complete the entire message serialization routines and a deadline timer the TESTBED will run standalone continuously. Prob. only take another day to complete that. We are also making attack vectors as base classes so new ones can be easily created via overrides. *ie plugin-like attack vectors
Russell O'Connor [9:22 PM] https://lists.linuxfoundation.org/pipermail/lightning-dev/2015-August/000135.html
bitPico [9:26 PM] Yes; that idea and our attack vector(s) makes the entire network fall apart. We will prove this works. (edited) When nobody trusts nobody the network collapses. Low level attacks requiring no fees are easier however. (edited) There is nothing to prevent spoofing via replay of older packets. Because onion routing requires decryption (CPU Intensive) this can also be used to clog pathways with old payloads via CPU exhaustion. (edited) This is the real reason why ToR is so damn slow; it’s constantly attacked. It has nothing to do with end users actions.

Save one or two ...
bitPico [9:40 PM] (#)761 doesn’t impact our AV_03 It does however cause nodes to use more CPU and possibly go to disk per the notes. If LN nodes must go to disk this is bad. The slowest code pathways make the best AV’s.
bitPico [9:52 PM] CircuitKey’s are allocated “on the heap”. (edited) Underlying implementation would use malloc/realloc/free. Instead of RAII. This is asking for an overflow into unknown memory segments. We suggest stack only allocation. Memory on the stack is trivial to maintain; it has no holes; it can be mapped straight into the cache; it is attached on a per-thread basis. Memory in the heap is a heap of objects; it is more difficult to maintain; it can have holes.
Laolu Osuntokun [9:59 PM] @bitPico cpu usage is super minimal, this isn't tor so we're not relaying like gigabytes unknown memory segments? golang is a memory safe language stuff goes on the stack, then escape analysis is used to decide what should go on the heap
bitPico [10:00 PM] Heap allocation is more of a concern here. golang is not memory safe; it uses C underneath.
Laolu Osuntokun [10:01 PM] uhh
bitPico [10:01 PM] golang is not written in golang :slightly_smiling_face:
Laolu Osuntokun [10:01 PM] yes it is... https://github.com/golang/go/blob/mastesrc/runtime/map.go GitHub golang/go go - The Go programming language
bitPico [10:02 PM] That’s like saying the C runtime is C and not ASM. The C runtime is ASM.
Laolu Osuntokun [10:02 PM] go is written in go before go 1.4 (maybe 1.5) is was written in c but still, your "attack vector" isn't an implementation level issue, it's a network/kernel level DoS recycling, syn cookies, etc, would be needed not impl level defenses (edited)
bitPico [10:07 PM] We know the answer but what does golang compile to?
Laolu Osuntokun [10:07 PM] also replay htlc's will be rejected native?
bitPico [10:08 PM] ASM
Laolu Osuntokun [10:08 PM] yeh...
bitPico [10:08 PM] So what we said is exactly true.
Laolu Osuntokun [10:08 PM] no?
bitPico [10:08 PM] It’s as vulnerable as we stated.
Laolu Osuntokun [10:08 PM]
the heap is a heap of objects; it is more difficult to maintain; it can have holes
bitPico [10:09 PM] It still allocates through OS heap memory and not onto the stack in your case here. Which means it has holes.
Laolu Osuntokun [10:10 PM] aight, lemmie know when you exploit these issues in the golang runtime here's the code if you wanna study it: https://github.com/golang/go/ GitHub golang/go go - The Go programming language
bitPico [10:11 PM] ASM is ASM. Heap is heap. Heap is bad in this case. Stack is wise. Same applies to C or C++. Avoid the heap at all costs.
Laolu Osuntokun [10:12 PM] aye aye, capt
stark [10:12 PM] replied to a thread: Seeing bad OP-SEC on LN; don’t name your node as the type of hardware. Those raspberry pi’s will go down. don't name your node at all....
bitPico [10:12 PM] https://www.cs.ru.nl/E.Poll/hacking/slides/hic4.pdf
Laolu Osuntokun [10:13 PM] cool, i'll be waiting on those exploits in the go runtime, i'm sure many others will be excited as well
bitPico [10:14 PM] Has nothing to do with go. It uses malloc underneath. Heap always uses malloc; go, c or c++ or java or whatever.
Laolu Osuntokun [10:15 PM] sure, i think many of us know how memory management works
bitPico [10:15 PM] http://security.cs.rpi.edu/courses/binexp-spring2015/lectures/17/10_lecture.pdf Security experts avoid heap allocation. This is common knowledge. Noticed somebody commented about performance of the PR. That is because of the use of heap allocation instead of stack.
Laolu Osuntokun [10:17 PM] no, it's because of the disk I/O
bitPico [10:18 PM] So LN nodes write data to disk in case of crash? As to not lose funds? That’s what the PR says. Anyway golang uses libc; it is not compiled into pure ASM. (edited) Nevertheless we are not focusing on golang; LN in general and TCP/IP stacks.
ɹɑd [10:22 PM] @bitPico write an exploit and get back with us. Until then it just sounds like concern trolling.
bitPico [10:24 PM] Funny, we are exhausting LN TCP/IP Stacks as we type this… It’s no good if we can overtake the TCP stack and run it out of FD’s. We have 100's of connections to LN nodes and it;s automated using our hand built attack toolkit. When we increase this to 1000's then what?
Matt Drollette [10:26 PM] Isn’t that true of any TCP service though? Or are you saying there is something Lightning or lnd specific about your method?
Laolu Osuntokun [10:26 PM] it's true of any TCP service the defenses are on the kernel level
bitPico [10:27 PM] You’d need to have LN code handle millions of connections to mitigate this. We know golang will crash if this happens. But so will C.
Matt Drollette [10:29 PM] I’m beginning to wonder if @bitPico is actually performing a meta-attack on Lightning. A denial-of-service at the developer level with all this subtle trolling
bitPico [10:29 PM] This first problem is LN keeps inbound connections alive. It does not handle and drop them like a webserver. This is the only reason webservers can scale. Apache uses a timeout of 3 seconds in most cases. Currently we are connected to 45 LN nodes with over 22K connections. One variable change on our end and the network will suffer. (edited)
Matt Drollette [10:31 PM] but is that variable on the heap?
bitPico [10:32 PM] On Linux consider forcing it to require 999999 FD’s. AND do not keep-alive connections. The variable is an enum (an integer). Attack aggressiveness
Matt Drollette [10:33 PM] I’m just joking with you :stuck_out_tongue: I look forward to the write-up on the attack
bitPico [10:33 PM] Otherwise our code will keep LN nodes hung in TIME_WAIT. Anyway we are not trolling; we are BTC whales and LN must not fail. Otherwise our investment suffers. The only motivation behind this testing… As it stands LN nodes need L7 LB. Code will run overnight; sleep before we continue. Good job though on LN so far.
bitPico [10:46 PM] uploaded and commented on this image: Screen Shot 2018-03-19 at 1.44.19 AM.png
Fun stats: We’ve sucked 3.3 GB’s of bandwidth per hour from LN nodes. This will continue while we sleep. Every 80 milliseconds there is 44 attacks being performed.
bitPico [10:48 PM] :sleeping:
kekalot [1:35 AM] Seems likely. They were also the one who claimed segwit 2x would continue after it was officially canceled. Matt Drollette I’m beginning to wonder if @bitPico is actually performing a meta-attack on Lightning.

bitcoinhunter [3:07 AM] So you put down the network @bitPico or just DDosing dev`s time ?
kekalot [3:08 AM] technically youd need multiple people to be doing it to be considered DDoS this is just DoS
Mike Rizzo [7:57 AM] joined #lightning-network.
Alphonse Pace [8:31 AM] bitpico: are you bragging about attacking computer networks on here?
Bear Shark [9:54 AM] That was the funnest 5 minutes of my life. Watching a guy go from bragging about attempting a DoS to deleting the account.
aceat64 [9:56 AM] Reporting an attack vector is fine, releasing PoC code is fine, but actually DoSing a network is a crime, and to just go online and brag about it, wow The only way that could have been worse would be if they didn't use a pseudonym
Bear Shark [9:58 AM] It's fine. He was probably sitting behind 3 tor exits and 10 VPNs (edited)
chek2fire [10:09 AM] i see c-lightning is always at 80% cpu usage
Russell O'Connor [10:12 AM] Did bitPico delete their own account themselves?
kekalot [10:26 AM] @alp?
Alphonse Pace [10:27 AM] I banned. zero tolerance for illegal shit.
chek2fire [10:29 AM] and he says hitler is alive :stuck_out_tongue:
chek2fire [10:43 AM] i dont know why but the new version of lightning-c has a huge cpu usage (edited)
chek2fire [11:06 AM] is there possible not compatibility from lnd to c-lightning? i just connect bitrefil and they say that in their lnd node bitrefill payments works in my c-lightning is not working when i try to do a payment with their ln links i always get this "code" : 205, "message" : "Could not find a route", "data" : { "getroute_tries" : 2, "sendpay_tries" : 1 } }
hkjn [12:00 PM] was that just-banned bitpico the same one as this one? https://lists.linuxfoundation.org/pipermail/bitcoin-segwit2x/2017-Novembe000689.html
Russell O'Connor [12:02 PM] I believe they claimed to be. It's hard to know for sure I guess.
Matt Drollette [12:03 PM] Lest we forget.
ASM is ASM. Heap is heap. Heap is bad in this case. Stack is wise. Avoid the heap at all costs. - bitPico

camelCase [10:28 PM] could be possible to run two lnd nodes in sync between them? i mean wallet-wise (edited)
Justin Camarena [8:02 AM] Bitrefill getting DDos'd lol that bitpico tho
Brandy Lee Camacho [8:21 AM] joined #lightning-network.
chek2fire [8:53 AM] my c-lightning node has very high cpu usage is always at 80% in the same time bitcoin node is at 15-17%
Gregory Sanders [8:58 AM] @chek2fire could be the gossip silliness that's being worked on, or bitPico :stuck_out_tongue: probably gossip inefficiency
chek2fire [8:59 AM] maybe someone dos my node i dont know
Laolu Osuntokun [11:46 AM] time to learn how to use iptables folks
Sent from my Space Ship (edited)
camelCase [11:50 AM] anyone knows if what i asked above is possible? like running two or more nodes that replicate the wallet so you avoid having your channels offline
gonzobon [11:55 AM] https://twitter.com/alexbosworth/status/976158861722726405 Alex Bosworth ☇@alexbosworth Lightning nodes are getting DDOS'ed, rumor is that someone from the 2x effort known as "BitPico" has taken credit for this. The Lightning services I've deployed have been attacked from the start, with botnets, etc. Deploying in adversarial conditions, decentralization is hard.
Twitter Mar 20th
camelCase [11:56 AM] well... at least we know we wasn't trolling about that lol
v33r [11:58 AM] https://twitter.com/alexbosworth/status/976158861722726405
gonzobon [11:59 AM] beat you to it @v33r_ :stuck_out_tongue:
Tomislav Bradarić [12:23 PM] something something good for bitcoin but really, better to see how sturdy things are now than when lightning starts getting adopted more, like how the last rise in popularity was at the same time as blockchain spam
gonzobon [12:28 PM] andreas put it in context as a good testing opp.
Hiro Protagonist [1:04 PM] I so wanna get my old sysasmin-devops team together to start running lightning nodes under these conditions. Every website is attacked relentlessly by DoS, spoofing, etc. Defences exist but you need skills to figure out what to do.

Bitcoin Core Wallet sync 100% result Mooncoin Wallet sync fix Syncing bitconnect wallet with network. Bitconnect wallet (not sync) *fix*. BitConnect Wallet Not Syncing? The Fix! 09 Windows Wallet Stuck Syncing

Either the wallet synchronization process will be slower or it gets stuck at certain block and it won’t sync at all. So why your wallet won’t sync or is slow and what to do if it is not syncing / processing the blockchain? Wallet synchronization. Bitcoin, Dash, Litecoin and every Altcoins has its own core wallet. Ahhh one of the worst things about Bitcoin.... I have dealt personally with this issue.

Digital money that’s instant, private, and free from bank fees. Download our official wallet app and start using Bitcoin today. Read news, start mining, and buy BTC or BCH. At some point, pretty much everybody who uses cryptocurrency will come across this problem: your wallet just won’t sync. It gets stuck on a certain block and won’t download / process the rest of the blockchain. Bitcoin Core treats its block database files as 100% accurate and trustworthy, whereas during the normal initial sync it treats each block offered by a peer as invalid until proven otherwise. If an attacker is able to modify your block database files, then they can do all sorts of evil things which could cause you to lose bitcoins.
