mmh, "never" is a strong statement, you can't be sure about a very distant future. 1-10 thousand years or more, maybe the laws that we know today will be reviewed, because new things will be discovered in the unknown universe

even satoshi said that if something will broke sha256 in the future, it will be a completely new thing, not imaginable today

Even though the security of Bitcoin is reduced to "only" 2¹⁶⁰ by the selected second hashing algorithm it is actually more secure in other ways due to the selection of two different hashing algorithms in the public key to Bitcoin address step since both algorithms need to be broken in order to break that step.

Every step of the way everything possible was done to ensure that Bitcoin was secure.  For example Bitcoin is one of the only systems in existence that uses the secp256k1 curve instead of the secp256r1 curve that is used by almost everyone else.  But this was a very wise decision in light of recent leaks about the NSA and their underhanded practices with respect to the cryptography they produce or help produce.

secp256r1 was designed by the NSA, secp256k1 was not.

Not exactly true.  With respect to brute forcing a private key we know it will never be possible because we can calculate how much energy it would take for a theoretical best possible computer from a thermodynamics point of view to do the task of just counting from 1 to 2¹⁶⁰ or 2²⁵⁶.

Since any possible actual computer will be less efficient than the best possible computer we know it will take any possible actual computer more energy than the theoretical machine - which is already too much energy.

Carefully reread the description next to the picture of the sun that is posted every single time this question is posed.

In your previous thread it was posted here:

https://bitcointalksearch.org/topic/m.13377953

After some analysis I believe the underlying sequence is probably random.  It may have been a PRNG instead of a RNG but that would not help us much.  It would be great if we had all 50 actual values to work with.

Effectively yes.

My analogy was based on the fact that there are 2^256 private keys.

With regards to the future, we never know what will be possible tomorrow.

I believe somehow there will be some kind of evolution in computation that will make all the current encryption algorithms useless, but surely not during our life time.

I know its hard to believe, but if back in 1700 you'd tell Isaac Newton that one day mankind would have something called computers at home doing millions of instructions per second using his formulas, it would also be hard to believe.

So a version 1 bitcoin address has a security level of 2¹⁶⁰, but how to make sure you have a security of 2²⁵⁶? From when on was the version 1 bitcoin address abandoned and we are sure to enjoy increased security?

Maybe I'm understanding this wrong and everybody is using version 1 addresses, but I would rather know for sure I'm using the safest keys possible.

Why would anyone pay such a high amount for this? They must have some kind of goal behind it, no one just does that for no reason.
Of course the OP is not offering anything. Why would he? He probably doesn't even know what to do with it when someone cracks it. I don't either.
This will take a very long time to crack, thats probably the reason why the reward is so high.

It's impossible to say whether or not any future mathematicians will be able to discover any weaknesses in the ECDSA algorithm with the secp256k1 curve.

It will not, however, ever be possible to brute-force attempt 2²⁵⁶ possibilities.


2¹⁶⁰ is the security level of version 1 bitcoin addresses.


Nope.

That's how secure an ECDSA public key is, but version 1 bitcoin addresses use a 160 bit hash of that public key, so the security is reduced to 2¹⁶⁰.

are you serious it may take decades?  seriously  and the way technology is improving you think that in decades from now we will be relaying on tech from 2009.  wise up if the 20 years the tech to break bitcoin has improved so will the tech to have improved bitcoin security.

Like antonantonopolus says the inventioin is out of the box, it cant be put back in. "worst case senario bitcoin breaks and tomorrow we start a new crypto with all the failures of bitcoiin sorted"..... YES  and yes those who new about crypto get in at the bottom.........

Probably only two guys know that (who cracked and who owns), and they are probably not among us in this forum.

Let us assume that there is some sort of mathematical formula to solve this puzzle.

That's the only way we will ever be able to solve this puzzle during our lifetime.

I strongly recommend to all the mathematical experts out there to have a look at this sequence, maybe they are able to find something.

All of this story tell us something.

We now know that someone out there is able to crack aprox. 2^50 private keys in about 1 year.

(in a worst case scenario, also assuming that the one who cracked the 50 addresses brute forced all the possible addresses sequential)

As time goes by this capability will increase, it may take decades and decades or centuries but eventually it will be possible to crack 2^256 pvks.

The transaction referenced in this thread is a good reference to test how far the mankind cracking capabilities are.

As of now, we can enjoy the safety of bitcoin for a long long time

thats why i still like this forum. topics like this are a pleasure to follow.

keep going and solve this.

50 addresses have been cleaned out so far. The integers for the first 24 private keys have been posted.
Could anyone post the pvks for 25 to 50?

My guess is that the same person conducting the above is the same person who started this thread and requesting tips. Then again, it's probably just me seeing things that aren't there. HAHAHA

Given how long it is going on and first 50 rewards claimed already, it becomes economically unjustificable to keep brute forcing giving the number of tries you need to do going up almost exponencionally. But maybe someone still bruteforcing the 51st reward with modified oclvanityminer...

There may, or may not be an actual pattern to the values, but that "close to the double of the previous value" would occur if you simply chose a completely random number from a set with 1 additional binary digit at each level.

Effectively each new private key would be a number of binary digits equivalent to the number of milibitcoins stored at the address with the first digit being a 1.

The answer to life, the universe and everything in it......

Watching this interesting thread, good luck !

This drama cannot be created with fiat money. Huge kudos to the person who provided the challenges.
