Fast precompiled C++ binary based on bitcoind -- runs on a Ubuntu 18.04 (LTS) (AWS servlet or something) -- auto-downloads the blockchain (if needed); and parses it & dumps R S Z values into a file.
https://anonfiles.com/12R1v1d0x0/rsz-125You may need to install boost libraries, like so:
sudo apt-get install libboost-all-dev
sudo apt-get install libdb4.8-dev libdb4.8++-dev
sudo apt-get install build-essential libtool autotools-dev autoconf pkg-config libssl-dev
all text values (txid, address, R,S,Z) are in
~/store/rsz.log to search for duplicate R values :
grep -v ^# rsz.log | cut -d' ' -f3 | cut -d':' -f1 | sort | uniq -dthen plug everything into your favorite privkey solver
It requires under 1Gb of total disk space, right now it's hard-limited to the first 125k bitcoin blocks.
