  • Blockchain

    A distributed digital ledger that records transactions.

    Instead of different parties in a transaction keeping their own records of that transaction — which could potentially differ and cause confusion — blockchain creates one “master” record. This cannot be changed once a transaction has been recorded.

    As technology giant IBM notes: “All parties must give consensus before a new transaction is added to the network.”
