Public keys for all addresses

[pbies]

With LoyceV we are going to put publicly all public keys for all 1... addresses.
I made the process and code, LoyceV will put it on his server.

Let us know if you are generally interested in public keys for all addresses.

Data will come from "blocks" and "chainstate" folders from Bitcoin Core.

What purpose would a log of all available public keys serve? I'm trying to think of possible reasons anyone would want that but I can't come up with any. Can you share what prompted the project?

What immediately came to mind was blockchain analysis/identity clustering, like those performed by chain analysis services. Or perhaps it could be a reference for certain statistical data (who knows).

This is the same as puzzle ( https://privatekeys.pw/puzzles/bitcoin-puzzle-tx ) - maybe someone would be happy to download fresh list of public keys for addresses.

Also there can be other usage which I don't know yet. However ppl are asking for public keys recently on the Internet.

We are in contact with LoyceV currently, I am preparing the file for him.

Maybe someone is preparing for the first available quantum computer to crack them all

What are we going to gain from you doing all this? I can't find any reasons maybe you can share.

Then why are you posting on the Dev board?

Are you sure you told LoyceV about this?

Yes. What's with the shitposting in this thread?
OP asked me to host the 40 GB file.

Though public keys are not private but don't you think putting them all in one easily downloadable database will make tracking and clustering much easier for analysis companies?

Oh noes, someone shares data from the blockchain! Those blockchain analysis companies would never have thought of that on their own!
/sarcasm

As for questioning why: it's data, and I like data:

Whoever wants it, can have it. If anything, you can use it to prove to yourself how secure Bitcoin is. Did you know that every time your wallet creates a new Bitcoin address, it's basically brute-forcing all existing addresses, even if it's just one address at a time? Everyone who ever installed a wallet has attempted to brute-force a funded Bitcoin address and failed.

Then you'd better think about maintaining a database of addresses with non-zero balances and keeping it up to date.

Because the quantum threat is about cracking transaction signatures using Shor's algorithm. It is also related to addresses whose public keys have already been revealed through spending transactions in the blockchain.

The quantum revolution is out, Op and LoyceV are going to lead that race here in the forum. We could all be mega rich here if things go well.

I have seen the data of all addresses having bitcoin and its importance, but I can't figure out the importance of this, except for sophisticated analysis.

OP uploaded the data, it'll be available on http://tmp.loyce.club/pbies once my move to a new server is complete. I hope within a couple of days.
