Blockchain isn’t just Bitcoin. It’s a decentralized ledger where every node validates transactions, eliminating trust gaps. For newcomers, focus on blocks, hashes, and consensus. For pros, dive into sharding, roll‑ups, zk‑snarks, and Layer‑2 scaling. Mastering smart contracts unlocks DeFi, NFTs, and DAO governance. Start with MIT’s OpenCourseWare, then experiment on testnets.
