Blockchains are the backbone of crypto, turning trust into code. A decentralized ledger uses cryptographic hashing and consensus (PoW, PoS, DPoS) to record immutable blocks. Smart contracts auto‑execute on platforms like Ethereum, powering DeFi and GameFi. Experts look to layer‑2 scaling, sharding, and privacy protocols. Beginners should start with wallets, staking, and gas fees. Master these to navigate the future of finance.
