Double-Entry Bookkeeping (Triple-Entry)

A traditional accounting method that blockchain-based systems extend into a ‘triple-entry’ model, where a cryptographically verifiable shared ledger entry accompanies each party’s own records.

Origin: the ‘triple-entry’ framing was popularised by accounting researcher Ian Grigg, describing how a shared blockchain ledger entry can serve as a mutually verifiable third record alongside each party’s own books.
