Abstract
A system and method for providing reputational information on users involved in transactions is detailed. The method includes evaluating fulfilment of transactions, particularly in the context of contracts, and providing a record of that on a blockchain through reputational information, which can be retrieved later. Similar reputational information for other transactions can be retrieved and linked to the same user, based on a hash of a master public key for a user. Aggregate reputational information can be computed from pieces of reputational information retrieved. The evaluation and record provision can be implemented using a deterministic finite automaton (DFA). For each user involved in each contract, the DFA not only configures and allows for implementation of the contract, but also considers the extent of fulfilment of the contract's terms. The DFA generates reputational information in relation to each user in each contract, and this reputational information is published to and stored on the blockchain.
