Blockchain

A decentralized digital ledger that records transactions across multiple computers, ensuring transparency, immutability, and security.

Decentralization: Data is distributed across all network participants (nodes).
Immutability: Once data is recorded, it cannot be altered without network consensus.
Transparency: All participants can view the ledger.
Consensus Mechanisms: Protocols like Proof of Work (PoW) or Proof of Stake (PoS) validate transactions.

Supply Chain: A coffee company uses blockchain to track beans from farmers to consumers, ensuring transparency and ethical sourcing.
