Alexander Spiegelman — DAG Meets BFT - The Next Generation of BFT Consensus

Alexander Spiegelman — Aptos Labs DAG Meets BFT - The Next Generation of BFT Consensus In this talk, I will present the recent development in the theory and practice of directed acyclic graph-based (DAG-based) Byzantine Fault Tolerance (BFT) consensus, which is currently being implemented by several Blockchain companies, e.g., Aptos, Celo, Mysten Labs, and Somelier. Specifically, I will talk about how Narwhal decouples data from meta to build a highly efficient DAG, and then I will explain how we can locally (with zero communication overhead) totally order the nodes of the DAG by using DAG-Rider/Tusk/Bullshark. This talk is based on three papers: DAG-Rider: All You Need Is DAG (PODC 2021). [I. Keidar, E. Kokoris-Kogias, O. Naor, A. Spiegelman], Narwhal&Tusk (EuroSys 2022 Best paper award) [G. Danezis, E. Kokoris-Kogias, A. Sonnino, A. Spiegelman], Bullshark (To appear at CCS 2022) [A. Spiegelman, N. Giridharan, A. Sonnino, E.
