Character Assassins for Hire: The Story Behind the ASICBoost & Extension Blocks Scandal

Bitcoin has a problem; the demand for Bitcoin far outweighs the bandwidth of transaction throughput that the network can sustain. The Bitcoin “highway” is constrained at 1MB per block, or one single analogous lane, which permits a “speed limit” of between 3.3 to 7 transactions per second.
