Unspent Transaction Output accounting model used in Bitcoin and related blockchains, where each coin is represented as a discrete unspent output that must be fully consumed and re-created by a transaction. The model enables straightforward parallel validation, eliminates double-spend via simple output-state queries, and underpins script-based programmability.
