blockchains are sometimes described as systems of proof. Smart Contracts To support the consistent update of information – and to enable a whole host of ledger functions (transacting, querying, etc) – a across the network – to ensure that ledgers update only when transactions are approved by the appropriate participants, and that when ledgers do update, they update with the same transactions in the same order which update the ledger are also shared. Unlike today’s systems, where a participant’s private programs are used to update their private ledgers, a blockchain system has shared programs to update shared
