Abstract
Computer-implemented systems and methods are detailed for establishing information on states of a machine-executable contract on a blockchain, for instance in the context of unspent transaction outputs (UTXOs) and the determination of states within deterministic finite automaton (DFA) implementations of contracts. The states are determined using agent public keys, each public key having metadata for information of interest associated with codes or tags. Each of the agents provides a respective public key into a multi-signature redeem script that generates a locking script, with a hash to which a scriptPubkey is designated. ScriptPubKey values of each script may be used to provide keys for use in constructing an external database and mapping the keys from the scriptPubKey values. Upon searching the blockchain, the database is used to determine if the information of interest is present in UTXOs. A match from the search indicates, in a definitive manner, the state.
