Re: A Two-Round Proof of Work instead of PoW

Please explain how a lower complexity reduces the amount of energy used when miners are encouraged to increase energy usage in order to be one of the first N2 miners. Whether it takes 1000000 tries on average or 1018 tries on average, miners are going to use as much energy as they can in order to be first.

Yes but Round one is only let's say 2min for the sake of argument. Once this 2min is over Only N2 miners will advance to Round 2 to work on the second puzzle. Let's assume Round 2 calculation time is 6min. We have N1 miners working for 2min and N2 miners working for (2+6)=8min. In Bitcoin we have all N1 working all 8min. We save energy on Round 2. N1-N2 miners are IDLE during 6min of Round 2. This is where we save energy. Now I do understand that miners can try to game the system and rent their machines to the winners of Round 2. But I don't know how practical it can be to do so.  

Doesn't this scheme compromise the security of the bitcoin network. I mean, the security aspect of it is based on the total hashrate at every moment in time. if at any moment it decreases...then there's a potential weakness.
Yes it does. It makes half PoW and half of luck. If this is good, then make it 100% luck. does it work? No. Its not secure.
This propose just lower security for name of "economical".

Re: Bitcoin Core 22.0 Released

Because of version number change, bitcoin.org website orders releases odd way.

https://bitcoincore.org

It's odd but it's probably not because of the name change because it appears that the posts are ordered by date but for some reason, the 0.21.2 version was posted on the 26th of October while the newest versions were posted prior to that date.
Ou.. ok maybe it was not about version number. It can be because of certifigate and maybe they did re-sign old ones also.

Hey guys,

Looking to see if anyone can tell me how to modify the Vanitygen code so that it will start searching at the same point every time and not jump around to another random search position.

Thanks in advance Shocked)
Are you trying to remove randomness or only like save / resume function?
If you are removing randomness, then it means, I will get also your private key if I run same code with same starting pattern.

Bitcoin needs Internet. So I dont see this as "Bitcoin" question at all.
If there is no Internet, there is no Bitcoin.

Hypothetical question,
If you would to like install cryptography weakness,
would that be good spot? (A backdoor)

I will admit, technically I dont understand what you propose. (details)

But questions is, what problem are you trying to solve?
energy? You cant save energy when it is proof of work.

Lets assume, somehow we come to agree to make Bitcoin HARDER (you know, lets burn some fuel) to solve. Lets say, we will somehow make it 10 times harder to solve.
Do you know what will happen? Bitcoin network will just ADJUST itself back where it was. (10 minute mark) It does not MAKE ANY difference.
You are making a change, which will not make ANY difference. Right?

When you go to Bitcoin Core source readme file ( https://github.com/bitcoin/bitcoin )
You will see very early line

What is Bitcoin? Bitcoin is an experimental digital currency that enables instant payments to anyone,

In my opinion, whole word is an experimental.
In that sense, I do not see why BTCitcoin would need to state itself as an experimental.
It is more than 10 years old. I would just say it is in active development.
