Satoshi Nakamoto\'s hidden achievement \'UTXO\' design spreads to altcoins

The UTXO (unspent transaction output) model, Bitcoin’s core accounting structure, is drawing renewed attention as a largely overlooked achievement of its creator, Satoshi Nakamoto. Onchain analytics platform Arkham said the importance of UTXO has not been sufficiently recognised. The term does not appear in Bitcoin’s 2008 white paper, though its mechanism is described. Several blockchains based on Bitcoin’s code use UTXO, and Cardano uses an extended version.
