From the genesis block to smart contracts, blockchain is more than crypto. It powers decentralized finance, supply chains, identity, and NFTs. For beginners, start with Bitcoin’s proof‑of‑work and Ethereum’s Ethereum Virtual Machine. Experts should dive into layer‑2 rollups, sharding, and zk‑SNARKs. Understanding consensus, cryptographic hash functions and tokenomics unlocks the full potential.
