Introduction to Selfish Mining
A tutorial on selfish mining, a cryptocurrency mining strategy where one miner creates a new valid block, and withholds it from the public blockchain, creating a fork. Matt Weinberg (Princeton) introduces a formal game to capture the rewards that miners get by participating in Bitcoin. He also presents the seminal “Selfish Mining” attack, which achieves strictly greater rewards in this game than following the Bitcoin protocol for sufficiently large miners.
