How Blockchain Works
Blockchain operates as a decentralized network of nodes (computers) that validate transactions through consensus. Key features:
- Decentralization: No single entity controls the ledger.
- Immutability: Data cannot be altered once recorded.
- Transparency: All participants view the same verified data.
- Automation: Smart contracts execute agreements without intermediaries.
Each block contains a unique cryptographic hash, ensuring data integrity.
