Now I open the hood. This course traces a Bitcoin transaction from send to settled and explains who actually enforces the rules. I cover the blockchain as a shared, append only public ledger, the distinct roles of full nodes, the rule enforcers, and miners, the block builders, the journey from broadcast through the mempool to a block and then confirmations, how blocks are cryptographically chained to make history effectively immutable, and how the network reaches agreement with no central coordinator through the longest-chain rule.
