This is where it stops being buzzwords and starts being computer science. Blockchain is not just blocks and coins. At its core, it is a replicated state machine, a distributed systems pattern that every serious builder needs to understand. And once this clicks, everything else you learn about Web3 will make so much more sense. In this video, we get into the actual mental model: - What "state" means in the context of a blockchain. - What a state transition actually is and how transactions trigger it. - Why every single node must compute the exact same result. - Why smart contracts cannot call random functions or fetch live APIs. - How thousands of computers stay perfectly in sync without a central authority. This is the episode where you stop being someone who has heard of blockchain and start thinking like someone who can actually build on it. This is Episode 3 of Decode: The Builder Journey, a course by Beenco Labs taking you from the fundamentals all the way to deploying on-chain. Caught up on Episodes 1 and 2? Good. This one builds straight on top of them. Next up, we are getting into hash functions, and that is where immutability finally becomes obvious. Follow the series. It only gets more interesting from here.
