How It Works
- Blocks: Data is stored in blocks, each containing a hash of the previous block
- Consensus: Network participants agree on the state of the ledger through consensus mechanisms
- Proof of Work: Miners solve complex puzzles to validate transactions (used by Bitcoin)
- Proof of Stake: Validators stake their coins to validate transactions (used by Ethereum)
- Smart Contracts: Self-executing programs stored on the blockchain
