Post by: pooya87 on June 03, 2020, 03:11:06 PM I need tool for automate this process. developers will never waste their time creating something that has no real world applications and that is the case with what you are asking. you either have to learn programming and write one yourself or try to convince someone that there is some usefulness to what you want so that they may make the effort...

If something like that is not available already, it could be an easy task for an experienced programmer. @COBRAS you might want to check the services board and search for a developer there, or open a new thread and offer a BTC reward. Title: Re: How to get pubkeys for many adresses ? Script or util needed. Post by: TheArchaeologist on June 04, 2020, 12:58:49 PM Can you give one or more of these 200 addresses? Assuming they are P2PKH addresses you should be aware of the fact the pubkey itself is not disclosed unless a transaction has been made.
Also, I'm wondering what your use case is for these 200 public keys? Title: Re: How to get pubkeys for many adresses ? Script or util needed.

I assume all of those addresses belong to you :P Also, I'm wondering what your use case is for these 200 public keys? I bet they are 200 addresses with most bitcoins in them that have a public key visible. So the OP can try to crack them. Good luck with that! BTW. If you try to crack keys, and happen to succeed, it is not very nice to steal from exchanges, because you would be stealing from a lot of people. Most of the biggest addresses are exchanges. A little better (although still not nice) would be trying to find private keys to some of Satoshis addresses. There are about 20000 addresses with 50BTC in each and public key is visible in all of them. But yeah. I don't believe you can find private keys to any of those addresses. So no worries. Atleast it is a good math/computer exercise if nothing else. Title: Re: How to get pubkeys for many adresses ? Script or util needed. Post by: pooya87 on June 05, 2020, 03:19:43 AM So no worries. Atleast it is a good math/computer exercise if nothing else. there are lots of more constructive ways that the time and effort could be spent that could maybe even help other people too. for example if you look at tech support forums there are always people trying to recover their lost wallets. the effort could be put into improving the open source recovery tools currently available. and they do need a lot of improvement. i doubt people who are trying to bruteforce addresses/pubkeys are capable of doing that though. most of them look for a compiled thing to run without understanding it.
