Using TXID to track your Bitcoin balance is as stupid as using bank note serial numbers to track the amount of money you have in your wallet.

The analogy isn't perfect, but I think it's a reasonable lay-person explanation. Just like someone can swap out a $10 note from your wallet and make you "lose" $10, transaction malleability means you can transfer Bitcoin and "lose" that transaction.
The best way to know how much is in your wallet is to count the notes, and the best way to know how much Bitcoin you have is to count the unspent outputs.

Why can't I sign and then broadcast my transaction??

Can someone please help me broadcast a transaction? I have the full redeem code, and my original Wallet address, it keeps saying "mandatory-script-verify-flag-failed (Operation not valid with the current stack size) after broadcast transaction". I have to sign it to receive the money to my address...? Why wont it work?!

How I scammed a scammer out of 0.001 BTC with RBF

A scammer named lawrence2276 tried pulling off a bitcoin trading scam on me. I pretended that the websites he sent were broken (using inspect element), until he finally told me to send directly to his address. I asked him if he could do a test tx where I send him 0.001 BTC and he sends it back. He agreed.
I sent this TX:
https://live.blockcypher.com/btc/tx/687fe72c6173f1ed2d9b4929ee4e4a1b85dd6d5e2f8773ed9ebab52a6e568295/
and the guy sent me back 0.001 BTC without waiting for confirmations:
https://blockchair.com/bitcoin/address/12CPhvSp88sv7QnwnzanzxV3bjm5m51TPx.
He didn't notice that I had RBF on. From here, it was simple to double spend the funds back into my own wallet.

Here's the double spend.
This is why you shouldn't accept zero confirmation transactions (especially ones with RBF enabled). If you want to know whether RBF is enabled, enter your txid on blockchair.com

More fun with OP_HODL (CheckLockTimeVerify)

Last week I wrote a post with a script to create a HODL address. A HODL address is a UTXO that cannot be spent until a certain epoch time or blocktime. It can be used to secure funds in a will or trust that has a designated maturity date. Or you may have some other reason to lock the funds, the point is that the UTXO can be physically verified to be funded, and under an unbreakable timelock.
I've liked the feature but have been frustrated that there is limited HW and SW wallet support for it presently. My previous post walked through how to make a segwit HODL UTXO, this post will detail how to make a BIP16 legacy P2SH HODL UTXO.
Similar to last week, I wrote a bitcoinlib script to do it, but this week I also went through the steps to do it on the CoinBin wallet. CoinBin is a JavaScript wallet that can (and should) be run locally. CoinBin, or raw python (bitcoinlib) are the only ways I currently know of to spend a HODL address.
Here's the basic rundown to create and fund your UTXO with CoinBin
  1. Use either Electrum or Bitcoin Core to collect a Bitcoin public and private key.
  2. Run the CoinBin app either locally (best option) or through the live site
  3. Choose New -> Time Locked Address
  4. Enter the public key (from #1) and either a block height or timestamp for your lock
  5. Hit Submit and record the address and redeem script
  6. Ensure you have accurately recorded everything in step #1 and step #5
  7. Send funds to the address recorded in step 5 as you normally would.
Here's the basic rundown on how to spend your UTXO with CoinBin
  1. Use either Electrum or Bitcoin Core to collect an address to spend your UTXO to
  2. Run the CoinBin app either locally (best option) or through the live site
  3. Choose New -> Transaction
  4. Enter the Redeem Script you copied in the creation process (step #5), then Load
  5. After a few minutes it should automatically load your UTXO into the form
  6. Enter the address you want to spend your UTXO to and adjust the output amount for fees
  7. Hit the question mark next to Transaction Fee for the calculator
  8. Hit Submit when satisfied and record the unsigned transaction data
  9. Select Sign on the top nav bar to begin the signing operation
  10. Enter your private key from the creation process (step #1) and the unsigned TXN
  11. Select Submit to produce the signed TXN
  12. Broadcast the signed TXN with either Electrum or Bitcoin Core
Note, if you try to broadcast before the UTXO's timelock expires, you will get a terse not final error in either Electrum or Core.
For Extra Credit, CoinBin can also be run against Testnet, but to do so you have to unhide the settings element, manually code the TXN input script and manually code the TXN nLockTime to sync with your HODL address.
Here are a Testnet and Mainnet HODL spend TXN I created in CoinBin * Mainnet: txid ea6a1...79d53 * Testnet: txid a8110...adc93

Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

Power of the Command Line (bitcoin-cli, hwi, electrum, trezorctl)

I think some of the console tools available with HW wallets today are greatly under utilized. Here's a quick write-up on how to create and sign a TXN very similar to 43d27...1fc06 found on the SLIP-14 wallet. I'll be using TrezorCTL, Electrum, and HWI for the signing. I won't go much into the setup or install, but feel free to ask if you have questions about it. Note, you don't have to use all three of these. Any one will produce a valid signed TXN for broadcast. I just showed how to do it three ways. Whats more some of the Electrum and HWI steps are interchangeable.
ColdCard also has a utility called ckcc that will do the sign operation instead of HWI, but in many ways they are interchangeable. KeepKey and Ledger both have libraries for scripted signing but no one-shot, one-line console apps that I know of. But HWI and Electrum of course work on all four.

TrezorCTL

This is the what most would think of to use to craft and sign TXNs, and is definitely very simple. The signing uses a script called build_tx.py to create a JSON file that is then used by the btc sign-tx command. The whole process is basically:
  1. tools/build_tx.py | trezorctl btc sign-tx -
This just means, take the output of build_tx and sign it. To copy 43d27...1fc06, I wrote a small script to feed build_tx, so my process looks like:
  1. ~/input.sh | tools/build_tx.py | trezorctl btc sign-tx -
But it's all very simple. Note... I used TrezorCTL v0.12.2 but build_tx.py version 0.13.0 1.

input.sh

```

!/bin/bash

secho() { sleep 1; echo $*}
secho "Testnet" # coin name secho "tbtc1.trezor.io" # blockbook server and outpoint (below) secho "e294c4c172c3d87991b0369e45d6af8584be92914d01e3060fad1ed31d12ff00:0" secho "m/84'/1'/0'/0/0" # prev_out derivation to signing key secho "4294967293" # Sequence for RBF; hex(-3) secho "segwit" # Signature type on prev_out to use secho "" # NACK to progress to outs secho "2MsiAgG5LVDmnmJUPnYaCeQnARWGbGSVnr3" # out[0].addr secho "10000000" # out[1].amt secho "tb1q9l0rk0gkgn73d0gc57qn3t3cwvucaj3h8wtrlu" # out[1].addr secho "20000000" # out[1].amt secho "tb1qejqxwzfld7zr6mf7ygqy5s5se5xq7vmt96jk9x" # out[2].addr secho "99999694" # out[2].amt secho "" # NACK to progress to change secho "" # NACK to skip change secho "2" # txn.version secho "0" # txn.locktime ```

Electrum

Electrum is one of the better GUI wallets available, but it also has a pretty good console interface. Like before you need your Trezor with the SLIP-14 wallet loaded and paired to Electrum. I'll assume Electrum is up and running with the Trezor wallet loaded to make things simple.
Like with TrezorCTL, Electrum feeds on a JSON file, but unlike TrezorCTL it needs that JSON squished into the command line. This is a simple sed command, but I won't bore you with the details, but just assume that's done. So the process in Electrum (v4.0.3) looks like:
  1. electrum serialize (create psbt to sign)
  2. electrum --wallet signtransaction (sign said psbt)
Still pretty simple right! Below is the JSON I smushed for #1

txn.json

{ "inputs": [{ "prevout_hash":"e294c4c172c3d87991b0369e45d6af8584be92914d01e3060fad1ed31d12ff00", "prevout_n": 0, "value_sats": 129999867 }], "outputs": [{ "address": "2MsiAgG5LVDmnmJUPnYaCeQnARWGbGSVnr3", "value_sats": 10000000 },{ "address": "tb1q9l0rk0gkgn73d0gc57qn3t3cwvucaj3h8wtrlu", "value_sats": 20000000 },{ "address": "tb1qejqxwzfld7zr6mf7ygqy5s5se5xq7vmt96jk9x", "value_sats": 99999694 }]}

HWI

HWI is an unsung hero in my book. It's a very small clean and simple interface between HW wallets and Bitcoin Core. It currently supports a good range of HW wallets. It keeps itself narrowly focused on TXN signing and offloads most everything else to Bitcoin Core. Again, I'll assume you've imported your Trezor keypool into Core and done the requisite IBD and rescan. And if you don't have the RPC enabled, you can always clone these commands into the QT-console.
To sign our TXN in HWI (v1.1.2), we will first need to craft (and finalize) it in Bitcoin Core (0.21.1). Like in Electrum, we will have to use simple sed to smush some JSON into command arguments, but I'll assume you have that covered. It will take an inputs.json and an outputs.json named separately.
  1. bitcoin-cli createpsbt (create psbt)
  2. bitcoin-cli -rpcwallet= walletprocesspsbt (process psbt)
  3. hwi -f signtx (sign psbt)
  4. bitcoin-cli -rpcwallet= finalizepsbt (get a signed TXN from psbt)
A little more involved, but still nothing too bad. Plus this gives you the full power of Bitcoin Core including integrations with LND (lightning).

inputs.json

[{ "txid": "e294c4c172c3d87991b0369e45d6af8584be92914d01e3060fad1ed31d12ff00", "vout": 0 }]

outputs.json

[{ "2MsiAgG5LVDmnmJUPnYaCeQnARWGbGSVnr3": 0.10000000 },{ "tb1q9l0rk0gkgn73d0gc57qn3t3cwvucaj3h8wtrlu": 0.20000000 },{ "tb1qejqxwzfld7zr6mf7ygqy5s5se5xq7vmt96jk9x": 0.99999694 }]

Conclusion

This may all seem like very low level coding, but is surprisingly simple once you get a knack for it. Whats more, all these platforms support testnet which allows you to practice with valueless coins until you get the hang of it. And, like many things in bitcoin, this is all (mostly) python, which is one of the easier languages to learn.
Enjoy

Dust attack?

Recently i updat my Trezor T to the newest version and I notice that someone send me a very small amount of Bitcoin. I follow the sending address and fund out that it was a couple of thousand of people that received same amount of Bitcoin. I did some reading about it and i find out that i could be dust attack and someone could trace my wallet if spend it and try to find out my real identity. i heard that Samuraj wallet have a option that you could marke TXid as "do not spend" , i tray to find out if Trezor have something thing like that in the options and i couldn't find it. So my question is how i can go about it. How can I mark that TXid to not spend it. My plan is to transfer all to new seed wallet but I don't want to include that dust in my transaction.

Possibly scammed, need any technical advice please! :)

Hi bitcoin!Situation:
I am a professional poker player and ventured deep into the abyss of shady/dodgy sites. Why I did so is still a mystery to me. Long story short, I finally made two withdrawals totaling approximately $3,500 to $4,000 via BTC. Next day, I load up my Ledger and see I have my balance. Awesome!
Oh wait...it's not spendable.Surely it just hasn't confirmed yet, right? No big deal.
Then I look at the transactions...https://blockstream.info/tx/35c1ff29f22c251b67829ce6046a7441aa81dd67d1b6b3fffb3c518fa7a19b2b
andhttps://blockstream.info/tx/e65394e7a7c8fce0eeabef3709368ad032bee7a531fed6ac002823c4ad697970
Previous withdrawals were sent to me with a more normalized fee structure.These were sent with what looks like a near-zero fee.
With my limited technical understanding of BTC, this means the transaction will either get stuck for a VERY long time, or it will never confirm and eventually be returned to him.This person has blocked me on socials and has said on the discord server for the site that "the site is better off without him"
(Basically as a good professional player he didn't want me beating his small community of players)
I'm ok with this as long as I don't get scammed.
Is there anything I can do at this point?

Edit #1: Thanks a ton to u/jcoinner for the extensive help with spending the unspent coins via CPFP (child pays for parent) The transaction appears to be confirmed!
Using CPFP has successfully spent the unconfirmed coins back to a different wallet of mine.
The txid is: 6d65c98ea01bad8d98045794729b7d1b93936a11faad0e3bd126e9223d2ee297
and appears to show a confirm and my coins are spendable.
I believe this persons' intention was
"Send a transaction that's very likely to fail and if it does I'll scam and if it doesn't...oh well."

Thank you so much reddit!

The power of "import electrum" as a python bitcoin scripting engine

I've been a big fan of Electrum as a wallet for a while now. Traditionally, when I wanted to do bitcoin scripting I would use either trezorlib, pycoin, or bitcoinlib. But recently I was digging a bit deeper into the Electrum source and found it to be one of the simpler python libraries to use to craft bitcoin transactions.
One of the nicer things about Electrum as a scripting engine is that you can drop the standalone app or AppImage on a system and run your scripts directly through the console. This makes doing things on Tails or other locked down systems much easier. To run one one of your scripts (without the event loop) simply type (assuming you correct the file path):
with open(r"myscript.py", 'r') as s: exec(s.read())
Obviously only do this with scripts you've personally authored. Never run random code on your machine especially when wallet private keys are in play.
There are already some great scripting examples in the electrum\scripts folder, but most of these use the event loop which brings in a lot of overhead. I found simple TXN processing can easily be done without spawning an full electrum thread. I'd be happy to PR the samples if there is any interest in this style from the maintainers.
Here's two examples I put together that craft a BIP65 spending transaction. It turned out to be much simpler than I imagined. I did it both in bitcoinlib and electrum. The structure is very similar and should hopefully be easier to follow. Feel free to start a PythonRoastMe on it.
Two things of note. I had to disable R-value grinding (nuked while loop) so that I had parity with bitcoinlib, which hasn't rolled it out yet. This is why the TXIDs differ. I also had to override the the PartialTransaction.get_preimage_script method since it makes certain multisig assumptions that don't apply to generic scripting.
Reference: * Electrum script to spend an OP_HODL P2WSH address (txid 3a461e6...78de2b6) * Electrum script to spend an OP_HODL P2SH address (txid a8110bb...3dadc93) * BitcoinLib script to spend an OP_HODL P2WSH address (txid 3a461e6...78de2b6) * BitcoinLib script to spend an OP_HODL P2SH address (txid a8110bb...3dadc93) * TXID 3a461e6...78de2b6 (P2WSH) on the blockchain * TXID a8110bb...3dadc93 (P2SH) on the blockchain * BIP-0065: OP_CHECKLOCKTIMEVERIFY (aka OP_HODL) * BIP-0141: P2WSH symantics * BIP-0016: P2SH symantics

Running My Own Tor Bitcoin Lightning Node

I've been using my own bitcoin lightning/full node for about a month now and would like to share my findings as well as ask a few questions to the community.
For those that might be curious as to my setup, I am using a Lenovo M900 ThinkCentre with a 1 TB Samsung SSD and 32GB of ram. I'm actually running several VM's on it, for different reasons. One of which is the full Bitcoin/lightning node using Ubuntu Desktop in which I dedicate 8 GB to (more than enough) and most of my disk space to. I wanted a power efficient setup so that I could keep it running 24/7 and this is about as good as it gets short of a Raspberry Pi. When I only have my Bitcoin VM running, I'm consuming ~10 Watts. With everything else running it's ~30 Watts. I bought all of the equipment used (apart from the ram) so it was very cost effective.
What I've learned in my experience:

Any info would be appreciated. If anybody has any question that they would like to ask me, feel free to ask!

Weird behavior when scripting electrum's ECPrivkey(...).sign_transaction(...)

Update

Nevermind... Electrum is performing low-value R-grinding and bitcoinlib and CoinBin are not. For anyone interested, the grinding code his here. Nuking the while look makes the sigs the same.
A few days ago I used bitcoinlib to create a OP_CLTV transaction. Tonight I did the same with Electrum 4.0.4 via python and my sigs don't match.
The TXN I'm trying to match is:
The TXN has the following characteristics:
When I try signing the sighash (pre-image hash) using both bitcoinlib and Electrum 4.0.4, I get different results. I coded the TXN through another wallet as well (CoinBin), and bitcoinlib seems to be producing the proper signature, but Electrum's seems off.
I'm sure there is something simple I'm missing, but I can't figure it out.
Here's a test script to illustrate the differences:
``` from bitcoin.core.key import use_libsecp256k1_for_signing from bitcoin.core import x, b2x from bitcoin.wallet import CBitcoinSecret from electrum.ecc import ECPrivkey from electrum.bitcoin import EncodeBase58Check
use_libsecp256k1_for_signing(True) sechex = '535b755a4c265772c4f6c7e0316bfd21e24c9e47441989e14e8133c7cb2f41a3' hashhex = '9039c54c1c34aa12b69b4dda962f501bb6c9cdb6745014ef326f5d4d0472aa99' seckey = CBitcoinSecret.from_secret_bytes(x(sechex)) sig = seckey.sign(x(hashhex)) b_wif = str(seckey) b_pub = b2x(seckey.pub) b_sig = b2x(sig) seckey = ECPrivkey(x(sechex)) sig = seckey.sign_transaction(x(hashhex)) e_wif = EncodeBase58Check(b'\x80' + seckey.get_secret_bytes() + b'\x01') e_pub = seckey.get_public_key_hex(compressed=True) e_sig = b2x(sig) assert b_wif == e_wif assert b_pub == e_pub print("wif:", b_wif) print("pub:", b_pub) print("sighash:", hashhex) print("bitcoinlib sig:", b_sig) print("electrum sig: ", e_sig)

Electrum

Electrum is one of the better GUI wallets available, but it also has a pretty good console interface. Like before you need your Trezor with the SLIP-14 wallet loaded and paired to Electrum. I'll assume Electrum is up and running with the Trezor wallet loaded to make things simple.
Like with TrezorCTL, Electrum feeds on a JSON file, but unlike TrezorCTL it needs that JSON squished into the command line. This is a simple sed command, but I won't bore you with the details, but just assume that's done. So the process in Electrum (v4.0.3) looks like:
  1. electrum serialize (create psbt to sign)
  2. electrum --wallet signtransaction (sign said psbt)
Still pretty simple right! Below is the JSON I smushed for #1

txn.json

{ "inputs": [{ "prevout_hash":"e294c4c172c3d87991b0369e45d6af8584be92914d01e3060fad1ed31d12ff00", "prevout_n": 0, "value_sats": 129999867 }], "outputs": [{ "address": "2MsiAgG5LVDmnmJUPnYaCeQnARWGbGSVnr3", "value_sats": 10000000 },{ "address": "tb1q9l0rk0gkgn73d0gc57qn3t3cwvucaj3h8wtrlu", "value_sats": 20000000 },{ "address": "tb1qejqxwzfld7zr6mf7ygqy5s5se5xq7vmt96jk9x", "value_sats": 99999694 }]}

HWI

HWI is an unsung hero in my book. It's a very small clean and simple interface between HW wallets and Bitcoin Core. It currently supports a good range of HW wallets. It keeps itself narrowly focused on TXN signing and offloads most everything else to Bitcoin Core. Again, I'll assume you've imported your Trezor keypool into Core and done the requisite IBD and rescan. And if you don't have the RPC enabled, you can always clone these commands into the QT-console.
To sign our TXN in HWI (v1.1.2), we will first need to craft (and finalize) it in Bitcoin Core (0.21.1). Like in Electrum, we will have to use simple sed to smush some JSON into command arguments, but I'll assume you have that covered. It will take an inputs.json and an outputs.json named separately.
  1. bitcoin-cli createpsbt (create psbt)
  2. bitcoin-cli -rpcwallet= walletprocesspsbt (process psbt)
  3. hwi -f signtx (sign psbt)
  4. bitcoin-cli -rpcwallet= finalizepsbt (get a signed TXN from psbt)
A little more involved, but still nothing too bad. Plus this gives you the full power of Bitcoin Core including integrations with LND (lightning).

inputs.json

[{ "txid": "e294c4c172c3d87991b0369e45d6af8584be92914d01e3060fad1ed31d12ff00", "vout": 0 }]

outputs.json

[{ "2MsiAgG5LVDmnmJUPnYaCeQnARWGbGSVnr3": 0.10000000 },{ "tb1q9l0rk0gkgn73d0gc57qn3t3cwvucaj3h8wtrlu": 0.20000000 },{ "tb1qejqxwzfld7zr6mf7ygqy5s5se5xq7vmt96jk9x": 0.99999694 }]

Conclusion

This may all seem like very low level coding, but is surprisingly simple once you get a knack for it. Whats more, all these platforms support testnet which allows you to practice with valueless coins until you get the hang of it. And, like many things in bitcoin, this is all (mostly) python, which is one of the easier languages to learn.
Enjoy

Where's My Money? Deposits And Withdrawals At Blockfi, Celsius, Crypto.Com And Nexo Compared

Does your crypto show up in your account? And can you get it back? Looking through 100+ complaints about deposits and withdrawals, the insights are obvious but good to know...
- They require additional information like tags (XRP, XLM)
- Had major software changes (BCH, BNB, DAI / MCD, ADA)
So if you're going to move one of these coins, make sure to not forget the extra information or wait a few weeks after the change (to give these companies time to get caught up).
Raw data is below, organized by company and whether it seems the complaint was resolved. Some important notes to consider
  1. Posts about waiting a few hours for a transaction to complete were not counted. Many times (most of the time?) when it takes more than 20 minutes, nothing is broken. E.g. High gas fees on the ethereum network will mean slower processing times for stable coins and other ERC-20 tokens. Less popular tokens, like GUSD, might require people manually going into cold storage. Large (> $30,000 USD) transactions require additional verification. If it takes > 8 hours then yes something is not right. And you should email support and start posting. Otherwise sit tight.
  2. Comments from different people on the same post saying they have the same problem were not counted for "scores". Most of these comments don't add useful information and make it harder to collect the data.
  3. Posts about fiat belong to a different category because a very different set of skills and software features are needed to safely move around dollars, euros, etc. This post is about whether or not your coins are likely to get lost or be unreachable.
  4. I asked "Did this get fixed?" to a lot of people who posted about problems. Not only to see how things turned out. Also to generate a possible data point about the quality of the post. I.e. Trolls and other "special" people venting online can be identified by not bothering to follow up or respond to questions. I also hope this encourages people to not forget to follow up a few weeks later and share a final outcome - good or bad.

Help with raw BCH transaction - Coinbase Multisig

Been trying to recover an old Coinbase BCH multisig wallet from back in the day and am running into errors after signing the transaction.

I followed this process to get the keys and auth script. http://blog.nerdbank.net/2017/08/how-to-sell-your-coinbase-multi-sig.html?m=1

Now that blockdozer.com is no longer up and running, these kinds of tools don't work like the original Coinb.in method - https://www.reddit.com/btc/comments/6bsc5m/used_the_coinbase_multisig_vault_recovery_tool/
https://bitcoin.stackexchange.com/questions/64493/restore-block-io-multisig-wallet-in-electrum

My last attempt was to use cryptoapis.io on postman to publish the transaction.

When I decode my transaction I get this:

Trolls and other "special" people venting online can be identified by not bothering to follow up or respond to questions. I also hope this encourages people to not forget to follow up a few weeks later and share a final outcome - good or bad.

KuCoin CEO Livestream Recap - Laatste updates over beveiligingsincident

Als reactie op het recente KuCoin beveiligingsincident organiseerde Johnny Lyu, CEO van KuCoin Global, op 26 september 2020 om 12.30 uur (UTC + 8) een livestream en kondigde hij meer updates aan over het incident.
Hij zei dat, volgens het laatste interne beveiligingsauditrapport, een deel van de Bitcoin, ERC-20 en andere tokens in de hot wallets van KuCoin werd overgemaakt uit de exchange, die slechts een paar delen van de totale assets bevatte. De assets in de cold wallets zijn veilig en ongedeerd, en de hot wallets zijn opnieuw ingezet.
We zoeken de reden voor het incident en houden gebruikers op de hoogte zodra het is bevestigd. U kunt er zeker van zijn dat als een gebruikersfonds door dit incident wordt getroffen, dit volledig wordt gedekt door KuCoin en ons verzekeringsfonds.
Hier is de samenvatting van de livestream.
Johnny legde eerst de tijdlijn van het incident uit, zoals hieronder:
Op 26 september 2020 om 02:51 uur (UTC + 8) ontvingen we voor het eerst een waarschuwing van het risicobeheersysteem, waaruit bleek dat er een abnormale ETH transactie plaatsvond met de TXID: 0x4b738df5d7f12e3fa1cbe83b8165c542da461ef0c9255fc1a3f275259a92623b
Vervolgens werden nog een paar abnormale transacties voor ETH en andere ERC-20-tokens gecontroleerd:

En alle abnormale transacties zijn afkomstig van dit portefeuilleadres: 0xeb31973e0febf3e3d7058234a5ebbae1ab4b8c23
Op 26 september 2020 om 03:01 uur (UTC + 8) ontvingen we een waarschuwing van het risicobeheersysteem met betrekking tot het abnormale resterende saldo van onze hot wallets.
Op 26 september 2020 om 03:15 uur (UTC + 8) heeft het KuCoin team een ​​speciaal team opgericht om het incident het hoofd te bieden.
Om 03:20 uur (UTC + 8) op 26 september 2020 sloot het KuCoin operatieteam met spoed de server van de wallet en ontdekte dat er na het afsluiten nog steeds gevallen van abnormale transacties waren.
Om 04:20 uur (UTC + 8) op 26 september 2020 begon het KuCoin walletteam met het overbrengen van de resterende assets van de hot wallet naar de cold storage.
Op 26 september 2020 om 04:25 uur (UTC + 8) begonnen het KuCoin walletteam, het operatieteam en het beveiligingsteam het incident te onderzoeken op basis van de verzamelde informatie en aanwijzingen.
Om 04:40 uur (UTC + 8) op 26 september 2020 heeft het KuCoin team een ​​communicatiekanaal opgezet voor belangrijke partners en marktmakers voor dit incident.
Om 04:50 uur (UTC + 8) op 26 september 2020 heeft het KuCoin team enkele eerste bevindingen gedaan met betrekking tot de reden voor het incident.
Om 04:50 uur (UTC + 8) op 26 september 2020 heeft het KuCoin walletteam het grootste deel van de resterende assets overgebracht van de hot wallet naar de cold storage.
Vanaf 26 september 2020 om 05:00 uur (UTC + 8) hebben we contact gehad met een groeiend aantal cryptoplatforms, waaronder Binance, Huobi, OKEx, Bybit, Upbit, Bibox, Gate, MXC, BitMax, BigONE, BKEX, BitZ, HBTC, Hoo, Crypto.com, Bingbon, Renrenbit, LBank, Max / Maicoin, CoinW en meer om verdachte adressen te blokkeren en de getroffen fondsen te traceren. Bedankt allemaal voor uw snelle actie en ondersteuning.

Ondertussen onderzoekt KuCoin het incident met internationale wetshandhavers, en we zullen beloningen tot $ 100.000 aanbieden aan degenen die ons geldige informatie kunnen verstrekken over dit incident. Neem dan contact op met [email protected].
Daarna beantwoordde hij enkele van de meest gestelde vragen:

Sent mistakenly 1 BTC to Huobi's cold, please help me to contact CEO (+1 year unresolved)

Hi everyone, 19 months ago I sent mistakenly 1 BTC to the Huobi's cold wallet. Yes, I'm retard, I feel terrible.
Transaction:
https://www.blockchain.com/es/btc/tx/4769c93d8c9e0d5eaf8311ac8af513e23096ae461da0256a77cf70ca73fd4e4b

How I send mistakenly 1 BTC to the Huobi Cold Wallet?
A day I was watching a BTC rich list and exploring the addresses. I'm unsure how exactly it happens because I verified the address, but when I sent 1 BTC I did mistakenly to the wrong address!!! I verified that I was sending to the correct address, but I had to remake the sendship because the wallet crashed, probably there was the problem, the huobi's cold wallet address was in the clipboard. Anyways I don't have certainty how it happens.List: https://bitinfocharts.com/top-100-richest-bitcoin-addresses.html
It was a mistake, I work often sending and receiving BTC. When you do a certain task all the days copying wrong data could be a TERRIBLE but EASY mistake to do, because we are humans and we fall in the trust. As you did a task correctly many many times you earn trust on yourself and try save time. If it didn't happens to you ever you aren't being honest.

7 months talking with Huobi Customer Support (part 1)
I tried to contact Huobi's customer support. First they first didn't understand me, thinking that I tried to deposit on Huobi and sent to a wrong address. After they understand they told me that the address doesn't belongs to Huobi and they can't help me. That is false, I did an investigation and they have direct relation with this address, they can help me. Read my following analysis please:

Huobi Ownership Analysis
Searching, sites says that the address belongs to Huobi Huobi support says that address doesn't belongs to Huobi
I don't know if belongs to Huobi or not, but I can deduct and track that the address is related with Huobi
Why? The address 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64 regulary sent big amounts to 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D
Then, is VERY PROBABLY THAT 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64 OWNER KNOWS 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER And the 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER can help me.
Searching, some sites (and sites like USDT Official page https://web.archive.org/web/20181113185656/https://wallet.tether.to/richlist) says that the address 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D belongs to Huobi
Again, I don't know really if the address is of Huobi, but I can deduct and track that the address is related with Huobi
Why? On my Huobi account I made only 2 BTC withdraws from Huobi in the past
2018-05-08 18:36:45 , txid: 0e6bf02323ebc166b6638afcd6170ecb73948748235e687def7e7a3cb1902fca , it has 239 inputs 2018-05-08 20:17:10 , txid: b59b988d642fe3773268e246ef1a0d048bbd3f734a611d00722b39126ed9e20b , it has 239 inputs too
In both transaction, all inputs are addresses that BELONGS TO HUOBI, because you huobi are sending me BTC
Both transactions has 39 addresses as inputs in common (all huobi address, maybe deposit addresses of anothers huobi users)
Example: 1M9ndPSQ4fmMKaKW2oX7LtjduDqYUcFKCW
Analyzing the transactions of this address, we can found many transactions sending BTC to 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER
https://www.blockchain.com/es/btc/tx/740236113bde5a95cfc168d732762be00eee435556c686b00b74b85b3e6c3f77https://www.blockchain.com/es/btc/tx/e2367daa464818d46da93e9a364f23536ef31e767f04cd01ff0a01e2baca6f87https://www.blockchain.com/es/btc/tx/5c16244c0efaba9aeb1e141e9ff4c8702f7a34f44bac73121ea6f55eb98adab2https://www.blockchain.com/es/btc/tx/69e73d1bbcdcb8ffacf0ea555298ee226f1740c02d1131e2db72e7ade32aace1https://www.blockchain.com/es/btc/tx/110eff2733a88b626ca38d63b9f2d8b6d5b3e26574f1d918c99c36c785eb0d56
User withdraw? No BECAUSE the amounts are lower than the quantity required for a Huobi withdraw (0.01 BTC) VERY VERY PROBABLY that 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER is Huobi And seeing all transactions, probably all of them are being used to pay USDT fees (i didn't study this part but isn't relevant)
Then, if 1LAnF8h3qMGx3TSwNUHVneBZUEpwE4gu3D OWNER is Huobi, you can help me High probably that you know the 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64 OWNER , address which I mistakenly sent 1 BTC
Please, tell him that give me back my 1 BTC
See my transactions asking the 3CBq.. owner give my BTC back: https://www.blockchain.com/es/btc/tx/d60eed9b025f9c5d3fe3b168e2f64e0abcb880123c1c0a51290eaeddbd60b8d7https://www.blockchain.com/es/btc/tx/0015646c3df821b035a15837b26c65f458276c05128bbaeae3293284d178d14e
sending to 1SentYou1BtcP1sBackToMeP1sNznQ1zH(read the address) and to 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64 with the same addresses used to send 1 BTC to 3Cbq7aT1tY8kMxWLbitaG7yT6bPbKChq64

7 months talking with Huobi Customer Support (part 2)
After understanding this , they asked me my consent to pay a fee. I agreed. After they asked me sign a message with my privates keys. I did it. And finally they tell me "Wait". I'm waiting 7 months ago, all months I ask and they ever reply the same "We will contact you". Now they told me " Hello,sorry for the inconvenience, we feedback your problem to our technology department. After a series of research and development, but it can not be solved. Please understand this. "
I want to think that the team is failing and Huobi isn't wanting steal my BTC. What they are doing maybe could be illegal. I'm thinking to talk with lawers on Singapore, I don't know what more to do.
I tried to contact the CEO Livio on Twitter ( https://twitter.com/livio_huobi ) but they don't reply me! I want to think that someone else is administering their account.

My ownership evidence:
