Did you know #Bitcoin Core currently implements 62 BIPs?
A BIP(Bitcoin Improvement Proposal) is a document that provides a clear standard if something is to be implemented.
BIPs are not obligatory, there are currently 166 BIPs that have a number, and a big part are not used.

Did you know the 1st #Bitcoin client did not start mining until another peer joined the network?
This shows that NOT even the 1st block was pre-mined in Bitcoin.

Here is a #bitcoin wallet with 34,685 BTC from June 2010.
It belongs to Laszlo(the pizza guy).
He posted this to show he implemented a counter for your hashrate.

Did you know using "Satoshi" as a name for #Bitcoin units was proposed in 2010?
Initially, Bitcointalk user "ribuck" proposed 0.001 BTC be named a Satoshi.
Later, concluded the smallest unit would be better.
(austrian was considered as an alternative)

0.03223686 ~ $1,300 UP FOR GRABS!
https://image.nostr.build/436056acc80e4f2eaca5d7f12a9f4fad9dc60f452692be74fce7fa632fdb5583.jpg
In this address bc1q7l0h956r8sqfzjw3278s35p43z0zzmqnfnmfr4 , there is 0.03223686 ~ $1,300 and they are up for grabs.
Why?
Well because this is a game organized by Wasabi Wallet called #HuntingSats, the scope is to challenge people to learn how to use Bitcoin wallets and be rewarded for their work.
More info: https://www.huntingsats.com/anniversary
https://image.nostr.build/e42f06fb0204761ff23b7122cac46570312fbabcbd440aa033d284949f290dcd.jpg
Each of the companies in the picture was given 1 of the 12-word BIP39 seed phrase that unlocks the wallet.
They will release the word on their Twitter(I know it sucks and all, but hey do you want the sats or not?) at any time between (today)23 January and 26 January
You should follow them and the #HuntingSats hashtag to get the word before anyone else.

https://twitter.com/BTCTKVR
https://twitter.com/SatsDontExist
https://twitter.com/Paralelni_polis
Each of the companies will release their word whenever they want and no coordination was done between the companies, which means YOU have to figure out the correct order of the 12 words.
There are 479,001,600ish ways in wich you can order the 12 words, and only 1 unlocks the Bitcoins.
Satoshis Don't Exist(the movie I'm directing) is one of the partners and this is the word we were given.

I'd wish you good luck, but luck has absolutely nothing to do with it!

Did you know there were 147 empty #Bitcoin blocks mined in 2023?
11% of all Bitcoin blocks don't have any TX inside them.
And there are 2 Mining pools, never mined any empty blocks!
Why do miners mine empty blocks?
https://image.nostr.build/6a805bea56f2a237d5e813233642685853be6ef12e96a32cc7b3781b16c16136.jpg
Miners have 1 job, ordering TXs in Blocks.
They hash all the data inside the block until the hash of the block starts with a certain number of zeros.
As the block data does not change, there is this field(nonce), where they iterate until the right block is found.
https://image.nostr.build/19116f3570326ba25457cd316c8c2656233f17c30292568368bd4b285b7784f7.jpg
So the only condition for miners to get paid, is they find the right hash.
(if block is valid :p)
But if they include TXs in this block, they will pocket the fees from them on top of the block reward.
So why would any (rational) miner ever refuse to include TXs?
https://image.nostr.build/7b3517301b32d4e26a5529c7669077f37fb07783402b223336400078a699679f.jpg
A pool constructs a block and partitions the amount of work/searching each individual miner does.
This way, smaller miners can be profitable.
But the pool sends the block + the hash of the previous block at the same time.
(as it builds on top of it)
https://image.nostr.build/45809c2c75255849624887b9204d0322995373fa9b3fad8a432495e02aeb24a4.jpg
Right after a block is found, the miner will send the nonce to the pool, and now he waits to get a new block.
Remember miners don't turn off their machines.
So while waiting for the next block from the pool, might as well mine mine something.
But he has no TXs to include!
Mining is a purely satistical game, the more hashrate you have the more lucky you are.
Sometimes, in that small time window when waiting for the new block, a miner will find a block.
The reason for empty blocks is the latency of communication between pools and miners.
These are rational miners acting in their economic interest.
That being said, it would be better for them to get more BTC fees + people get their TXs confirmed.
One solution for this problem is @StratumV2
Remember how the pools sent the block and previous hash to miners?
8/9
In StratumV2 the 2 are separated.
So the mining pool can look in their mempool for TXs that did not make it in the current block and send these block templates ahead of time to the miner.
This way if they find a block, they work on these ones straight away with no latency!

Well one reason might be the "r", because you can't really know the NUMS are really NUMS, i think.
If bitcoin needs a new hashing algorithm its most prolly fucked, and the chaos a change would cause it think it would die.

This is a mockup for a #Bitcoin wallet made on 28 October 2011.
The orange Bitcoin logo was not yet created!
Prolly the 1st attempt at creating a wallet for novice non-techie users.

I hacked an #ethereum wallet and took all the money!
Ran 16 servers for a whole day!
How did I do it?
What tools did I use?
Was it profitable?
https://image.nostr.build/9fc31f4bf1fff730ba6bcd77d2f056db2a01685df693042a9cd66ef3449f9337.jpg
1st of all this was a bounty.
I DID NOT STEAL THE ETH :D
Check Twitter and I am tagged in an Ethereum post.
Only used Ethereum 2 times, initially not interested.
The pictures are clues to a BIP39 seed which unlocks 0.1 ETH
Ok, let me take another look.
https://image.nostr.build/c19f45fc9fd0355d430142f0b09be8123d7d19908800b21fb5154a5973313d02.png
As all the words are from the 2048 known words Dictionary.
I took a guess for each picture and checked if it was in the dictionary.
Found 11, not sure about the 4th.
But it's one of the 2048 words, so I just need to try all of them.
Easy job for a computer :p
https://image.nostr.build/c389f1903b51e5c4593ddad812ca7ebf95f3b5f061f286a737159a686af7a680.png
Enter Seed Savior - Brute forces 1 word.
I just pasted the words I know and it showed all the possible valid 4th word.
As I know the address, I just have to search for it here.
Got 138 valid 4th words ,but my address is not present..
At least 1 of my guesses is wrong.
https://image.nostr.build/bce1ddadc9ccc24968f1bcb946a399516484b78a511049a08e07f7644584fbe1.png
Now really want to find the seed!
I went through each of the 2048 BIP39 words and looked to see if it matched any of the pictures.
It took 2 hours, to redo the list .🥲
Now I have multiple options for each position.
I have to hurry, this is public, others may be trying.
https://image.nostr.build/d8fc52f6111b676eb4cca3068d7fc48516ae81f75d413aff00cdc764a712bb5d.png
5 million options are not that many.
I just need the right tool.
Enter BTCRecover
A command line tool that I can tell it how to mix the words, and check if they generate the address I'm looking for.
My Mac M1 tries 90,000 seeds/second
Took 1 min, but NO LUCK!
https://image.nostr.build/c9a0500646cffa58725431e404e3b548565ae78e4e626ba09ff066a18ad4758d.png
This means that at least one of the possible words is incorrect.
So on one of the positions, I need to try all the 2048 words.
I will have 2048 options on that position.
Positions 4,6 I'm least sure of.
6 days is too slow, others may also be trying to crack the seed!
https://image.nostr.build/1d486c5d3d25551b59d036f8084389475f76ac861060dbf5a41c0cf431971b7d.png
What if I use all 3 of my laptops.
Together they try 170,000 seeds/second.
Nearly a 2x improvement.
I cut it down from 6 days to 3 days.
Need a bigger improvement, other may be cracking as I am!
My laptops are all cracking using their CPU.
I need GPUs, a lot of GPUs!
https://image.nostr.build/b08104b62d091aed7d6d33651065b500b839e48e8debe29d10e990cb498f63a0.jpg

There are 2 ways to do more calculations per second:
1) get hardware that can calculate faster
2) get more of the same hardware and run it in parallel.
A GPU is basically a LOT of tiny weak processors that run in parallel and that is why some things run faster on GPUs.
Luckily there are websites where people allow you to rent their powerful computers and you pay per minute.
I used vastAI as seemed to be the cheapest option.
Prices range from $0.3 to $1 (for my needs)
Pretty much all have strong processors, ones with more GPUs cost more.
https://image.nostr.build/cb41f12a282f452f0cac686752fe4e552449b832e0dfb2e2f94e967811f764ed.png
Ended up renting 16 servers and I was trying 1,096,000 seeds per second.
It would take 11 hours to try all my candidate words, and on the 4th & 12th positions try all 2048 possible words.
So pressed start and got some much-needed sleep.
https://image.nostr.build/18dd39b90e2ec95400ff34f2a2edd58fd19aac6aee2382201fe0248e6c771794.png
Woke up and Seed not found.
Angry and disappointed, I closed all the servers, as it cost me money to keep them up.
But then I looked through the list one more time, and wait a minute 8 is not a park, it's Hard Street.
Could it be?
https://image.nostr.build/8defd289c8896a9810f51daef3b5f6efb00820ca81b4fa6480b2231509e243fd.png
Used initial list of candidate words, but hard on the 8th position.
4 minutes later SEED FOUND!1!1
When you take out the server costs and donation to the person who made the tool, I was left with ~$50.
Best 50 bucks I ever made in my life.
(10 days of continuous work)
https://image.nostr.build/153d7e59f7ed28efe503685d406390cd077a2c9e3211e119d2630c22b33de872.png
Clarifications
I left out a LOT of things to keep it short.
Everything took multiple tries and 10 days of constant hair-pulling.
The 1st pic in the thread was taken right after I found the seed
The screenshots of the commands, I re-ran later when I documented the process.

This is MultiBit a #Bitcoin wallet launched on 12 September 2011.
The tagline was:
- Run it from your USB drive/ home computer.

One selling points was that you can open multiple wallets at the same time.
This should really put into perspective how primitive things were back then.
Btw you could not even import/export the private keys in early versions, no interoperability between wallets.
https://image.nostr.build/0e014e7b343d6a870caa8b577bef01e8ffd37fee164e87d67a2afdcd5e3383da.jpg
Even though the total size of the blockchain was 600M, the main selling point of the wallet was that it was a light wallet.
The whole directory was only 16M
The wallet would only keep parts of the blockchain that had its own transactions.
TXs it does not use were erased.

So what?
Well, this shows how in the early days the main focus was to make #BitCoin as easy to use as possible!
(yes they wrote it like that)
Also, think about this.
Everything you get by default and do with 1 click, was not even an option back then!

Did you know @ElectrumWallet was the 1st #Bitcoin deterministic wallet?
Before this people used to backup each individual key, and there was no restore function.
Also, the 1st wallet to implement "mnemonic" backups, way before BIP39.
https://image.nostr.build/d9ae4fc3faf3df35a138f7cc6f7263a974190910a3d9c4ec3478d3e82a87016d.jpg
Electrum wallet was announced on 5 November 2011 as a Lightweight Bitcoin Client.
It was the 1st modern Bitcoin wallet and brought features that improved the UX by 100x.
You did not have that many options back then.
https://image.nostr.build/49c1bda563c7624545c7cf8fff8a381a2f33390d2648a541f44a7815a8f5852d.jpg
You either use Bitcoin Core(not called Core at the time) or some custodial wallet.
Electrum introduced this server model where it's non-custodial, and you just ask the server for information about balances and broadcast TXS.
(there is a privacy trade-of)
Back then your Bitcoin wallet would generate individual keys for each of your addresses.
You may think, it's still doing that now, true.
But there was no relation between the keys.
And I do mean private keys, there were no English words associated with them.
https://image.nostr.build/297c412af2e759296217cd107495121799bdefb52f7f8c97d580984536d91546.jpg
If you restart your wallet you get new keys every single time!
Hence NONdeterministic.
The #Bitcoin community was aware of this YUGE pain and solutions were being discussed as early as June 2011
This resulted in the widely used BIP32 created in February 2012.
https://image.nostr.build/e8c8632115eaae08c500936ed1bb3a6a3e17bd23fbe65358d5ca56c62aed8de6.jpg
The 1st version of Electrum mnemonic backups worked similarly to BIP39.
- 12 words encoded using a 1626-words-dictionary.
- words chosen from poetry list on Wikipedia.
- encoding is designed, to avoid conflict with a patent.
- words were chosen to be easier to remember.
https://image.nostr.build/20ed0595bd1041def41d7d41929861abdd625bdedc9876b872b0840ed6755c3e.jpg
Meanwhile, in 2013 BIP39 was created and used together with BIP32.
Separate BIPs for each type of script/address, and the same seed can be used ever with multiple coins!
Deterministic wallets are a thing!
But there is there is a catch.
There are a LOT of derivation paths for each type, and new types may be introduced.
BIP39 encodes the secret in English words, but no information about the paths.
https://image.nostr.build/9b7e896e3f34ca98dafe5f9bb2c59f2088daec8d70b8da876ad204ee60e989c5.jpg
This is problematic, as different wallets use different derivation paths, so to be 100% sure of recovery in the distant future you need to back also derivation paths.
Plus you can't upgrade this standard.
The authors made this design choice on purpose.
A flaw in my opinion.
In 2015, with Electrum 2.0 a new and improved seed system was introduced.
(still used today)
Addressing the shortcomings above:
- it had a versioning system
- allows updates
- not dependent on any particular dictionary
However, how many of you are using Electrum seeds?
https://image.nostr.build/fb0441d400f844f26d81d3848bdab45b40c3733d5f5834d292d72ddb6988abad.jpg
BIP39 grew more popular and became the de facto standard.
Even though most people think "just the words" are a great backup, they could not be more wrong.
Not all wallets use the same derivation paths!
The fact that this website exists, proves the flaws in BIP39.

Did you know that #Bitcoin Core did NOT initially have a 21M cap limit?
Because of a C++ quirk, the original code that enforces the halvings would have restarted the halvings after the last halving, around 2214.
This was fixed with BIP42 in 2014.
(fix in pic)

This is the biggest loss in #Bitcoin history.
2,609 are forever!
23 transactions in Block 150,951 on 28 October 2011.
Why are they lost?
Who lost them?
https://image.nostr.build/71c8bc64385b27004fb8a1a2ad62427675f4c651736187c90719bacad4059bae.jpg
🧵Thread👇
https://image.nostr.build/598a59e142718d3203a8c2b15d0061120c21bf28dfa8babe617d89df4a42ec23.jpg
As the blockchain is public we can see which coins are provably lost.
We see coins being burned quite often in small amounts.
(prolly new tokens being issued on Bitcoin)
But if we look at the biggest losses, we can tell they were not burned on purpouse.
It's human error.
When you give someone an address you are actually giving them a box, which ONLY you have a key that can unlock it.
This is guaranteed by the fact that only the entity that has the private key corresponding to a public key can provide a signature to unlock the box.
These locks are called Bitcoin Scripts.
They are small programs that sit on top of each Bitcoin. When you move Bitcoins, when you run these programs.
If needs to return success, coins move.
And the good part is that you can add very various conditions here.
Multi-sig is an example of such conditions.
But it is up to you to make sure you set the right conditions.
One way to make an error would be to add someone's else address.
Another way is to add invalid address, or create some conditions that can never be fulfilled.
Bitcoin addresses have a checksum at the end to avoid sending Bitcoin wrong address.
This safety check is done in the wallet, there is no such check in the Bitcoin script.
To get an address Public Keys are hashed RIPE160.
The same hash function is also used in the script.
https://image.nostr.build/a6a8f455a7a0ccb0bec8290882cfef2fbf678e8b9004f32c57e416cec9d00dbb.jpg
All the TXs above have the same script.
The script says:
These Bitcoins can be moved by the public key that when hashed with RIPE160 has a 1-byte-output.
This is impossible, as the function always outputs 20 bytes.
RIPE 160 bits = 20 bytes
This condition can never be meet
https://image.nostr.build/329ca0a8d9bd3521e029c09871fce5d630a86be58a1755509cc08ced8f1d7e20.jpg
The TXs were constructed by Mark Karpeles aka MagicalTux CEO of MtGox.
We know this as he admitted it on #MtGox IRC channel
At the time worth only $10,957 and only a week of profits for Gox.
Today they are worth $120,200,000.

This was a problem because it was not the desired behavior for Bitcoin TXs.
In some cases could have led to network splits.
Plus, could allow for some attacks, where you can reduce the confirmation of a TX to 1, making it more susceptible to double-spending.

Later in BIP34 a new rule was added.
Each coinbase TX is to include the height of the block.
As each block height is different, this guarantees each coinbase TX ID will be unique.
Blocks with such coinbase TXs are version2
Last version1 block was 227,835 was mined in 2013

However, the 2 transactions above, are Coinbase transactions.
A coinbase transaction is a special transaction, that a miner uses to pay himself.
And because this is done from the block reward, there is no input to this transaction
(there technically is, but ignore this)

A "normal" #Bitcoin transaction has mainly 2 things:
- Inputs: where you spend from
- Outputs: Where you spend to
(+ some other data)
It's very uncommon for all the data to be the same for different transactions, so that's why the TX ID is unique(most of the time)
https://image.nostr.build/35fb8008ccc4198285b5f22f77393df594c06483a4c4f933034c167e025d158b.jpg

The TX ID(Transaction ID) is just a double-hash of the transaction data.
And we know that if we hash 2 different things we get 2 very different outputs.
And ofc, hashing the same thing gives the exact same results.
(some theoretical caveats, but nvm)

I'm sure everyone expects that each Bitcoin transaction is unique, I mean we are trying to solve the double-spend problem here.
And something called the Transaction ID, should serve as a unique identifier.
But clearly, that's not the case(at least in the 2 examples)

Before anything, this is not the only example of the same transaction being in two different blocks.
This is another example.
There are only 2 such occurrences, and both of them are coinbase transactions.

Even though there were some plans to improve this by Satoshi, this never happened and it got removed.
In the end the cons severely outweigh the pros and it just made more sense to build such functionalities outside of Bitcoin.

The truth is that the pros were heavily outweighed by the cons.

This operated under the presumption that you are always online.
Which is not that crazy, considering you would if you were mining plus most p2p applications operate like this.

The advantage of using Pay-to-IP:
Better UX.
You just send 1 thing to sender, and then that's it.
You only send an IP - shorter than an address
Better privacy.

The software really only needs to Public Key, and an address is a Public Key with extra steps.
Making it:
- safer - error correction(checksum)
- shorter - hash160
- human friendlyer - base58 encoding
Also quantum proofing as a side effect(with caveats)

You are also correct regarding collisions with addresses.
When calculating the Bitcoin address you at some point do RIPEMD160 and you can find colissions there.
This project focuses on this https://lbc.cryptoguru.org/about
The probability of collision is 100%(because of the pidgeon hole principle:p)
