blockchain
Cryptographic transaction record
A blockchain is a digital record-keeping system where data is stored in linked blocks, each containing a cryptographic reference to the previous one—making the chain extremely difficult to alter retroactively.
The technology underlies cryptocurrencies like Bitcoin but has broader applications in contracts, supply chains, and voting systems.
The transaction was verified on the blockchain.
