Where can I find more details of this? I'm going to write one for libbitcoin, but if one already exists then I'd rather build on and use that. Something simple like: - Set previous block hash, set current target - Start hashing - Connect and send to specified host (i.e localhost) That way I can force re-organisations and stress the blockchain algorithm. Should be trivial for me to build, but worth asking anyway :) Thanks
