Bluestreak: Uncertified DAG BFT with Sparse Metadata

본문 미리보기

DAG-based Byzantine fault-tolerant (BFT) consensus lets all validators propose concurrently, and uncertified designs such as Mysticeti skip per-block certification to achieve low latency. In existing partially synchronous round-based DAGs that use only hashing and standard signatures, however, every block references a quorum of previous-round blocks, so block metadata grows linearly with the committee size and, even in the happy case, the metadata communicated per round grows cubically. We pr
