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.
