Blockchains and protocols are interrelated concepts, but they are different.

💡 Blockchain: A blockchain is a decentralized ledger that tracks all network transactions. The key feature is that this ledger is decentralized, meaning no single authority controls it.

💡 Protocol: The protocol is a rulebook that defines data formats, blocks, and the ledger and consensus mechanism. It ensures the security, transparency, and proper functioning of the blockchain.

In short, the blockchain is the physical system, and the protocol is the set of instructions that governs how it operates.
