Abstract
A blockchain system is enabled to participate in distributed transactions that uses a two-phase commit protocol ('2PC'). In a 2PC, a computer system, such as a DBMS or blockchain system, commits a transaction that changes data (e.g. database, world state) using two phases. To participate in a distributed transaction using 2PC, a blockchain system executes a “staged transaction”. A staged transaction transitions through the 2PC phases. In the prepare phase, the new values for world state records are staged in staging records as staged values. In the second phase, if the distributed transaction is to be committed, the world staging records are set to the staged values.
