Tar was very very very very good, I don't understand how it went over the radar.
The best way I would describe it is Taxi Drive but it is about a genius lady fictionalised conductor, that runs into a bit of agro.
What I really liked about it is that it makes you ask questions and be inquisitive to what really happened and what you actually are reacting to and at the same time criticizes the oversensitivity of Western Culture, but not by a morally superior protagonist.
On the same topic, with a different twist, Maestro is an absolute masterpiece.
While Tar tries to be as tamed as possible and serve the story with tack-sharp cinematography Maestro, goes all the way and takes full advantage of all cinematic forms.
This is a biographical about the real-life conductor Leonard Bernstein.
Then, what becomes one of my favorite movies of all time, Asteroid City.
I mean the movie initially seems to be an allegory about art and what it means to be an artist, which really means to be yourself in the world and tell the world how you feel about it, which brings light to the fact that all art is social commentary.
So all these 3 dynamics are happening at the same time in a very Wes Anderson world.
Also a similar topic, but through a different lens I have to mention The French Dispatch(2021) also by Wes.
The Fabelmans, heavily inspired by Steven's Spielberg life follows the story of a kid who loves movies and his struggles with being a kid in a family with some odd circumstances.
And yes, it is made by Steven Spielberg.
The ending scene is one of my favorite cinema movies of all time.
Kinds of Kindness is very fucking weird and makes you go like, what in the fuck did I just watch, but then as soon as the shock wheres off it makes you question so very basic way in which you interact with people and who others interact with you.
It's very loud and your face(stylistically) but at the same time so subtle in its observations.
And ofc cinematography is out of this world.
Licorice Pizza was a very Paul Thomas Anderson Movie(as all his movies are), and it's a story of a kid falling in love with this older girl that takes place in the 70s.
Sounds basic, but it's so masterfully done and such a beautiful way to show the thrilling aspects of the banal.
I really liked that new Cruela movie, I mean very Joker-type of movie with a lighter tone.
Brings the back story of Cruela from 101. A rollercoaster of a movie.
In the last 5 years we have 2 Scorsese movies: Killer of the Flower Moon and The Irish man, I mean they are both perfect movies. Absolute 10/10 movies. MUST WATCH!
Watching Killer of the Flower Moon in the cinema was one of the most intense movies viewing I ever experienced in my life.
Uncut Gems it's just one of those movies that kick you in the teeth and somehow you can't look away and it feels like the whole movie took 5 minutes.
Marvelous storytelling and such a cleaver story.
Godland is the most Tarkovsky movie I say that was node made by Tarkovsky. Also the only one on the list that's not an English language movie.
The Killer. David Fincher doing Le Samouraï(1967) in his own way and with all the freedoms allowed by Netflix.
Besides the exceptional word-class storytelling, I really love how Fincher portrays every small thing in such a realistic way.
I'm gonna stop here, as the tweet is way too big.

But more importantly in what order are they done?
I am interested in when the node checks the TX against its UTXO set?

I will release a short filme(before Satoshis Don't Exist), but its not nostr specific.

One very important clarification!
This particular attack actually "encodes the secret key into low entropy secret nonces and uses them in signing", so it's not just grinding the nonces.
What does this mean?
In the "classical" nonce-attack you either need a LOT of computer power or a LOT of signatures, which makes harder to pull off.
In his variant above they reduced this to only 2 signatures (for 12 words 4 for 24 words) vs ~64 signatures for the classical attack.
(again a lot of caveats I'm hand waving :p)
which is a great improvement and way easier to pull off and requires fewer steps to be taken by the person being attacked.

Well your other alternative(similar to Sparrow) is Electrum, but you have no install an extra thing(Electrum Personal Server), which in essence gives you the same functionality that Sparrow gives when you connect directly to your Bitcoin Core running locally on same device.
Then the hwi, that people referenced, but if you asked this question, i dont think this option will suit you :P

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.

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)

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 was not around in 2010, but from what I read on the forums, the 1st client that was made public was a CUDA client released by user puddinpop(bitcointalk) after Jeff Garzik donated 10k BTC to him.
But I think the reason OpenCL is used by Laszlo is because he was a Mac fanboi(I think he is also 1st to offer binaries for mac), and OpenCL was created by Apple.

2024-01-21 14:32:03

Did you know Laszlo (the 10k pizza guy) was the 1 GPU miner?
In 2010 when he emailed Satoshi to tell him about his feat, Satoshi was against using GPU mining too early and wanted to keep difficulty low for as long as possible.

Ran 16 servers for a whole day!
How did I do it?
What tools did I use?
Was it profitable?

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

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.

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.

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!

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!

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.

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.

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)

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.

Usually, I tweet one interesting #Bitcoin fact every day!
This is the only Ethereum fact I have(story more than a fact :p)
Btw the #BitcoinFactOfTheDay was brought to you by BitBox !🇨🇭🔑

2024-01-16 16:29:09

Did you know in 2014 someone uploaded their #Bitcoin wallet to the internet?
The wallet had 10 Bitcoins.
This was done to show no one can break the encryption protecting the wallet.
https://image.nostr.build/0f41d739e1cd13081818a3fa66b43fd9647f9dd56d92f2874ebac2bd4c55bbb5.jpg

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.
https://image.nostr.build/2937665b838de64718c9b7c14a17004d8909e25a810edc620f5b51cce860bc49.jpg

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)
https://image.nostr.build/18c5811a521c46f1d938c819f54dc1f37a1d57476fee9034168a37a3f5ca8d1b.png

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

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.

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

This problem 1st was addressed in BIP30.
Blocks are not allowed to contain a TX with the same ID as a previously not-spent TX.
While this solved some of the problems, it's still not enough.
Also, the BIP has specific exceptions for the above-mentioned TXs.

So when the same outputs are used, the coinbase transactions have the same transaction ID.
They obviously are 2 different transactions in 2 different blocks, and are paying 2 different things, but they both pay to the same output.
(Here the output is a pay-to-pub key)

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)

Man in The Middle Attacks.
There was no authentication method when using Pay-to-IP, so someone could intercept the communication and switch up with their own public key.

The truth is that the pros were heavily outweighed by the cons.
IP is a terrible identifier for an entity.
Also starting around 2009 static IP usage was less and less.
Never mind that IP leaking has privacy drawbacks.

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.
Think Bittorrent.
So this is a disadvantage vs an addresses, when you don't need to be online.

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.
Makes fresh address use each time easier.

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)
