David Mazieres, Stellar co-founder, discusses the origins of the Stellar Consensus Protocol, drawing parallels between decentralized systems design and his earlier work on peer-to-peer file systems. He explains how the protocol was inspired by internet architecture and designed to prevent forks through network effects rather than proof-of-work.
In this fireside chat at Builder's Bridge, Stellar co-founder David Mazieres traces his intellectual journey from early peer-to-peer systems research at Harvard to designing the Stellar Consensus Protocol. He describes his formative experiences fighting centralized access controls in operating systems and file systems, which shaped his philosophy that smart people should have equal access to APIs regardless of status. Mazieres explains how he approached the consensus problem in 2014 when Jed McCaleb approached him, initially exploring epidemic consensus before finding inspiration in internet architecture. The key insight was replicating the internet's bottom-up coordination through ISP peering relationships, where the network effect of interoperability creates overwhelming incentives for consensus rather than forks. He addresses questions about validator participation, MEV concerns, and Stellar's potential as a global layer one for central bank digital currencies, drawing an analogy to SMTP's role in unifying email systems.
