Re: List of all Bitcoin addresses ever used - currently UNavailable on temp location
Have you considered creating a script to update your existing list once you have a list of addresses? Your script could start at block_n and add an address if it is not already in your list. This should reduce read/write operations pretty significantly.
That's what I tried to do for the addresses in chronological order, but it gave inconsistent results (and due to the time it takes to test it, I'm still not confident on this solution). I could probably do the same for the sorted addresses, by using comm instead of sort. That means only reading the compressed big file from disk, reading and sorting the weekly addition, and writing the new compressed file to disk. This does make more sense
