Alberto Sonnino - The Story Behind Mysticeti, Sui’s Consensus Algorithm
Timestamps:
(00:28) Introduction and background
(02:03) From academic prototypes to building real systems
(06:38) Narwhal/Tusk and the "mempool saga"
(10:05) FastPay
(10:55) Libra winding down
(12:13) Origins of Sui
(16:18) Mysticeti
(22:30) Recommended reading
(24:40) Looking ahead: execution, privacy, usability, and building real applications
Description:
In the fifth episode of Honest Majority, we speak with Alberto Sonnino, Research Scientist at Mysten Labs, about the design and evolution of Mysticeti, Sui’s consensus protocol. Alberto traces his path from distributed systems research to building production blockchain infrastructure, including lessons from moving from paper prototypes to real-world systems. We unpack Mysticeti’s core ideas, DAG-based consensus, latency and throughput goals, and how it differs from earlier BFT and leader-based approaches, and discuss how consensus design interacts with networking, execution, and broader system assumptions. We close with Alberto’s recommended reading for getting up to speed, plus a look ahead at what matters most next: execution, privacy, UX, and building real applications.
