@electrum-cash/network is a lightweight JavaScript library that lets you connect with one or more Electrum servers.

This script connects to a locally running full node core wallet, scans a specified range of blocks,and extracts public keys found in transactions into an archive.Used for public key research projects such as RCKangaroo,keyhunt,BitCrack,bsgsd,keyhuntcuda,etc. for BTC,ETH,BCH,LTC,DOGE,DASH,ZEC,etc.

This program reads a file containing public keys and compares them to addresses containing balances. If they match, the public key and address containing balances are output to a file. Used in public key research projects RCKangaroo, keyhunt, BitCrack, bsgsd, keyhuntcuda, etc.
