From 1b4a3d24ff2883adea5a5147291cff140ada10b0 Mon Sep 17 00:00:00 2001 From: Christopher Goes Date: Thu, 22 Mar 2018 18:47:13 +0100 Subject: [PATCH 01/94] Implement basic proof-of-work module & add to basecoin example Module users specify a coin denomination and proof-of-work reward. Blockchain clients can then submit SHA256 Hashcash solutions and receive the reward, with a constantly increasing difficulty. Includes replay protection to prevent the same solution being submitted multiple times, and inclusion of the rewardee in the hash data to prevent others from submitting the same solution once they see it in the tx pool.
