Direct Acyclic Graph (DAG) Based Consensus Protocols: An Introduction | a16z crypto research talks

YouTube video

A tutorial on direct acyclic graph (DAG) based consensus protocols. Andrew Lewis-Pye (London School of Economics) introduces DAGs, which allow blocks to have multiple parents or children, thus resolving the problem of “forks” in blockchains. The resulting structure is a Directed Acyclic Graph (rather than a chain). Andy introduces how to think about such structures and then focuses on state-of-the-art protocols such as Cordial Miners, DAG-Rider, and Bullshark.
