These slides reveal how distributed systems survive when parts of them lie. In environments where trust isn't a feature but a vulnerability, Byzantine Fault Tolerance keeps systems running correctly even when up to one-third of nodes act maliciously or send false data.

Each slide unpacks the Byzantine problem at the heart of decentralized consensus — and makes one thing clear: blockchains don't trust validators, they verify them. Because consensus isn't just a feature; it's the infrastructure that makes verifiable agreement possible without central authority or blind trust.
