Shared ledger with consensus
Blockchain stores ordered records in blocks linked by hashes; participants validate new blocks via consensus.
- distributed ledger
- hash chaining
- consensus
- immutability
- peer-to-peer
Structure
Transactions are grouped into blocks; each block references the prior hash.
Consensus
Nodes agree on valid blocks using proof-of-work, proof-of-stake, or variants.
Trust Model
Security comes from decentralization, cryptographic signatures, and auditability.
