Blockchain is a decentralized ledger that records every crypto transaction immutably, validated by consensus algorithms like PoW or PoS without a central authority. Smart contracts power DeFi, NFTs, supply‑chain tracking, and DAOs. Beginners need to understand distributed ledgers, hashing, public/private keys, and mining. Experts explore scaling, sharding, and security protocols. Master these basics unlocks deeper insight into crypto ecosystem.
