thanks a lot. if I cannot do it myself, I will definitely use your suggestion
I am trying to get a list of all used bitcoin addresses. Only with balances does not fit
I was going to recommend you looking this: List of all Bitcoin addresses ever used, but it is currently unavailable from LoyceV's web server.
I then saw that it was uploaded in notatether.com: https://files.notatether.com/public/loycev/addresses_sorted.txt.gz
Quoting the message itself:
For anyone stumbling open this in the future, I have created a torrent for this file, which accesses the web link.
Web Link: https://files.notatether.com/public/loycev/addresses_sorted.txt.gz
Torrent Magnet URL
.torrent file, good until 2022-09
This is up to date as of 2021-08-12. It will not be updated in the future, but is being left here to help, at least for now.

Answering to how to distinguish a Bitcoin address from a regular text:
A bitcoin address is an encoding of three things:
For example, this is an address: 1EKdAmcXiSXXAL18eJuWCZYj7k7zLGwXXx, because once we decode it we get:
The first one is indeed the prefix. The second one is indeed a 160-bit number. The third one is indeed the first 4 bytes of the doubled hashed with SHA256 prefix plus 160-bit hash.
So, if someone gave you a string that once decoded with base58, it satisfies the above, it can be used as an address.
A bitcoin address is an encoding of three things:
- A prefix that indicates the network. (“00” is for legacy addresses and “05” for p2sh on main net)
- A 160-bit hash.
- A 4-byte checksum.
For example, this is an address: 1EKdAmcXiSXXAL18eJuWCZYj7k7zLGwXXx, because once we decode it we get:
00 921f507bd82b94dabe9f8f281dccdfc2c6bd3ecc 5774bebb
The first one is indeed the prefix. The second one is indeed a 160-bit number. The third one is indeed the first 4 bytes of the doubled hashed with SHA256 prefix plus 160-bit hash.
So, if someone gave you a string that once decoded with base58, it satisfies the above, it can be used as an address.
trying to get all used bitcoin addresses
I don't know if you care about the way you'll get them, but there are already written in a frequently-updated txt file: List of all Bitcoin addresses with a balance
I have this type of text. I do not know how to extract addresses from it without regrex.

Does it have to be regex? Or can it be any other function?
I am parsing by regular expression transactions from BitcoinCore base.

maybe you can count the sum of letters or something like that or change the pattern?
