讲座摘要:
Selfish mining of Blockchain is an important phenomenon or evolutionary behavior in Proof of Work (PoW) consensus mechanism and Tree Representation with multiple block branches. It is interesting, difficult and challenging to study such a Blockchain with multiple selfish mining pools. In fact, we have not yet discovered the most basic models and their associated mathematical theory in the study of Blockchain selfish mining in a general technical sense, such as Bitcoin, Ethereum, smart contract and so on. This research is a key to motivate our exploration and finding from chains, trees to directed acyclic graph (DAG) in order to express a complete evolutionary and growing process of Blockchain. This talk gives several key points of Blockchain selfish mining as follows: (1) Why to generate the selfish mining; (2) some key results from two mining pools; (3) some key results from multiple mining pools; (4) several difficult and challenging problems we face in the future.
