主权项

1. A method for processing a transaction, the method comprising:
decoupling a validation operation from one or more of a read operation, a write operation, and a compute operation of a transaction to establish a set of transaction operations; responsive to a first transaction operation of a set of transaction operations reading a first record, issuing a read subscription; responsive to a second transaction operation of the set of transaction operations modifying the first record, issuing a write publication; notifying a subscriber when a third transaction operation of the set of transaction operations modifies the first record; and entering a commit phase of the transaction based upon the following conditions: (i) the read subscription and the write publication are both complete; and (ii) the set of transaction operations are complete; wherein: at least the issuing a read subscription, issuing a write publication, and committing the transaction steps are performed by computer software running on computer hardware.
