Topic: Bitcoin puzzle transaction ~32 BTC prize to who solves it - page 213. (Read 215272 times)

I can't see any computer there... I can only see a one big mess in a ruined interior. I hope its not your home.

I understand you want to try cracking bitcoin puzzles and of course it your choice. You can try for example program called bitCrack.

But i can see you totally don't understand whats going here - all puzzles till 65 bit are solved. So now you could try bruteforcing puzzle 66. Before you start you must realize what a puzzle 66 means.

I can write a long story but i will write you this short: you will never solve it and you will be just wasting time and electricity. Its too hard to crack it if you dont have a huge processing power. As huge processing power i don't mean a powerful PC. I mean like 200 GPU farm.

First of all you should learn how many combinations exist in a 66 key space. Then you could see how many attempts per second your computer is making...and you will see how incredibly low your chances are to solve it.

Mining any shitcoin will make you almost zero profit...but trying craking remaining bitcoin puzzles on home computer is pure stupidity.

I'm not trying to make free money if you could see my life you wouldn't think that. I have been trying to earn my bitcoin for many years. I started in 2017 in cryptocurrency faucets to collect my first fractions of bitcoin until faucetbox ran away with the users' satoshis I lost 0.00130000 satoshis and then I decided to start mining I used my personal computer extracting monero in minergate until 2019
2 years lost mining for free for minergate until when the pool began to keep the cryptocurrencies of the miners I lost 0.03 xmr.
going to share my situation this is my equipment 
silver computer is the one I'm going to use. It's getting dusty. I just want to occupy it with something. I need to configure this.

You are not wrong, but he doesn't know anything about the subject, so explaining the technics won't help.

From #1 to #65 by brute forcing and from #65 to #120 by public key collision were the easiest tasks, from now on things are massive, requiring advanced tech. Still possible though if you spend some money.

Being precise it needs to be told that for puzzle transactions where we don't know public keys there is only one method currenly : bruteforce.

 Correct me if i'm wrong.

What was removed from github? This is not something for people to try and earn money, we are looking for ways to hack bitcoin addresses, there are so far 2 methods, one is brute force which is generating bitcoin addresses one by one to see if we can generate one of the puzzle addresses or not. The other way is more advanced and requires decent hardware, with normal home computers you can't try the second method.
My advice, if you are after earning money, this is not for you, others have already collected the easy coins, but if you think you can find some ways to hack bitcoin addresses then you should visit project development and technical discussion boards to read some useful posts.

First of all you should realize how hard it will be for you to solve any remaining puzzle. (i guess you not have a massive GPU farm)

I read the repository I am not an expert but I want to try this because mining already died for me. I tried to mine bitcoin and the pools always disconnected me I think they ignored me because I am not an ASIC team now I want to try this but there is no one to help me you seem know a lot about running this. Could you please teach me 🙏 I'm a bitcoin enthusiast but I can't against. the mining asic and I want to waste my time. github it seems that it was removed

I get it now .. Thanks 👍

While elliptic curve and RSA encryption are different, 160 bit elliptic curve is not used in bitcoin. I would say in order to find a private key by knowing the public key in secp256k1 (bitcoin) you'd need to crack a 2048 RSA key. I might be wrong. According to my own knowledge, the security of bitcoin is 128 bit, if I'm not wrong we'd need to do 2^128 operations to find the target private key.  I would say a very *strong QC, could crack the 2^80 operations in a few days, considering they have a few million terabyte in RAM.

*= in 15 years from now.

Well said .. i just showed the gentleman that when using pub key attack you would be 1 billion trillion times faster than mere sha256 cracking .. although the it's not even always the case unless you're using BSGS and even then my numbers are too optimistic.. also by calculating private key from pub key, you are basically using compute units to make complex operations other than simply iterating through hexadecimals then converting them to hash160 like the case with private key cracking .. and yet somehow my words aren't convincing.. But let's assume we are using Kangaroo to attack with pub keys, my last example was a VERY optimistic scenario that resulted in 23 million years of work to arrive at an address .. here is the same example in plain text for those reading this .. let's say you use a code that acts like JeanLuc's kangaroo on quantum computers after creating the quantum circuit correctly, all this means is that you are a few billion trillion times faster (again, absurdly optimistic numbers) than cracking using say a quantum code equivalent to bitcrack.. you're still left with more than a dozen million years because guess what, you have no idea where this pub key will eventually land ..

However, luck always scares me when it works in the favor of an attacker, a malicious attacker could run such code in a random mode and hope to land by coincidence on an address with balance .. at least they have an advantage of more speed .. say roughly a billion times faster than a powerful classic PC. Problem is, it's still bound to luck.. because without luck, a billion times faster in ECDSA is just peanuts. Actually No, even peanuts is an overstatement. But yet again, luck knows no laws. It's just it.

This is quoted from RESEARCHGATE website:
 

Someone enlighten me, if the above was true.. why isn't Qiskit or IBM a dozen billion dollars richer? According to the abstract above, they both clearly have the qubits necessary to attack ECDSA with Shor lol . Something is not right. This is either overrated estimation of the strength of quantum bits, or IBM/Qiskit are angels.

It's the opposite, FYI ECDSA and SHA-256 are entirely different, they just happened to operate in the same bit range. SHA-256 is used all around the world for many purposes and is more prone to fail from a collision attack.
In ECDSA, more specifically in bitcoin, you have a barrier called computation cost, whilst in SHA-256 you don't need to compute so much as you need to do in bitcoin.

I believe no one with a quantum computer would directly and publicly attack bitcoin addresses, not everyone is a criminal. As history is my witness, technology/ knowledge, is not given to a certain group of people, it's given to many in different parts of the world, that's why we have pyramid shape structures all over the world, that's why we usually hear different names when we talk about the greatest inventions, the knowledge is somewhat evenly distributed in a timely manner. Point being, if the bad guys have their weapons, the good guys also have their defense system.

I'm afraid you're confusing two separate things. It is one thing to break sha256 (which is probably quantum resistant) and another thing is to derive private key from the public key when ECDSA was used.

There is a Shor algorithm which, in theory, running on a suitable quantum computer will allow you to obtain
private keys from public keys (of course not from addresses). And that privatekeys don't need to be with leading many zeros - we are talking about keys generetaed using the whole availabe range.

This is the fundamental problem that people don't understand. The vulnerability is in ECDSA, not the SHA256 hash function.

No patronizing intended at all. Just stating a fact. Some research about qubits will reveal how extremely unlikely for it to act as a threat to current strong hashing algorithms (except for the media, which is using naiive headlines to gain attention through generating doubt). And i know for sure that you're not talking about individuals, because an individual cannot even afford a portable quantum computer let alone a 1mil qubit one. And I'm not seeing the advantage of concatenating several quantums into one coz if you can't create more noisy or stable qubits, then you're just creating a chain of server-like computers. Also don't let those revealed pub keys deceive you into thinking it's getting any easier to crack. Knowing a pub key of puzzle 120 is nothing like knowing a pub key of a well randomized pvt key for an address. Which is the case with all those rich addresses you see now. Never expect to find an address with 2 million bucks worth of bitcoin that uses a public key for a private key of more than 3 leading zeros. Good luck trying to calculate that using a pub key on a quantum device or any device for that matter. Sure, quantum is insanely faster than classic PCs, but most people don't know the fact that numbers will still beat the difference in performance between the two. If govs know that all it takes to break sha256 is spending a few billions, then this would have happened already. Lucky for Satoshi and us, it should cost way WAY more than that.

Now let's talk numbers to put things in perspective:

- a typical quantum device is 158 million times faster than the strongest computer on earth
- say you have a supercomputer that goes through 1000 TRILLION private keys per sec.
- you would need 3671743063080802746815416825491118336290905145409708398 years to crack every bitcoin address.
- with quantum device you would need less than that... Only  23238880146081030043135549528424799596777880667 years lol.
- say you did something to quantum tech and moved it up so fast .. like insanely fast that it gave you a critical advantage and shortened this period down and you're 1000 TRILLION times faster, then, and only then, you'll be able to do the cracking job in just under 23238880146081030043135549528425 years
- Say that when using a pub key calc. Instead of private key cracking, you are now saving time and you're 1 BILLION TRILLION times faster, awesome! Now you can easily calculate the keys in only 23 Million years.

Fun fact: If one day you find out that any bitcoin burn addresses got emptied, you can be 100% sure someone found a way to break sha256 😃 Because you know, obviously no one is supposed to know the private key for a burn address.. even Satoshi.

Keep your patronizing tone for yourself.

Reserach is currently underway on a way to scale quantum computers through connecting them. So everything points rather into direction of connecting many smaller quantum machines into one than building giant quantum computer.

I can only agree that we don't know when it will occur - but im sure at some point IT WILL OCCUR.

BTW I never said  such machines will be available for average person soon. I meant more about government agencies or military where cost isn't such a big problem (the same way you can't buy and any private corporation dosen't have nuclear weapon despite it clearly exists).

I can also agree that we are still far away from a machine that could crack private keys from public keys getting them from unconfirmed txs (there is a small time limit to make it) - but there is a ton of loaded addresses with available public key which you can try to crack for as long as you need (exactly the same way you crack bitcoin puzzles now).

Your response clearly shows a lack of Qubit-related knowledge. Quantum computers are not magical beings. They consist of qubits which are different from classical bits. However, you CAN estimate how much bits in a bitcoin pvt key would be cracked by counting how many qubits you have .. you need 1 million Qubits to crack a full sha256 private key. So again, neither time nor resources are enough to make one such computer with that gigantic amount of qubits. Hence, from 3k qubits to 1mil qubits, there will be a huge time difference to close the gap between those two numbers. You basically can start worrying at 500k qubits. As for resources, checkout how much a small portable quantum computer costs and you might get a feel of how much resources you need to even start creating a quantum device with such amount of qubits.

They can steal some bitcoins first  and then make profit of selling quantum computers. Double money 

You will, because the people who make quantum computers will eventually want to make (guaranteed) money out of it, so they will sell them to normal people and normal businesses, who will then take a shot at trying to break cryptography for a few crypto addresses. And because normal people are terrible at keeping secrets, it will be easy for reporters to latch on.

This is what we officially know. It hasn't to be true.

Quantum computer is kinda like weapon. It's smarter not to tell how far you are with that technology.

It will not be announced in media like: " Attention ! We have a quantum computer powerful enough to crack your cryptography. Please move everything into post quantum cryptography and stay safe. Thank you."

Nobody would tell you if such possibility would exist.

BTW... I bet in that case it will be not used to simply steal bitcoins. I guess it can be used to DESTROY bitcoin by slowly destroy trust into bitcoin by cracking some addresses in a way you cant be sure if it was a quantum computer or something else.

So , no ... you will not have enough time to move everything into post quantum cryptography cause you simply don't know the REAL progress in that area. Additionally it's much easier to move banking and other FULLY CENTRALIZED systems into PQ cryptography than moving something decentralized like bitcoin.

The biggest quantum computer ever exists is merely 3k qubits .. find me a quantum computer with at least 500k qubits and then we could talk about Bitcoin vulnerability 👍 and it's not a matter of time until it gets broken because that time is more than enough for all algorithms in the world to migrate to quantum-safe tech. Bitcoin will not be an exception then.

JeanLuc is a God. He doesn't die.

Yeah, imagine that, a super fast quantum computer sitting and waiting for a large amount in a transaction to compute it's private key in a 256 bit range to do what, steal them? There is a solution for that, connect your node directly to honest miners and broadcast your tx to them, they will mine your large sum tx. However there is a problem with that, the thieves could double spend the txs before the block reaches maturity, there is a solution for that, turn off RBF. Now go and see what are they doing about turning off RBF. The problem is not with bitcoin.
