Abstract

Integrating a blockchain ledger with an application external to the blockchain ledger is disclosed. A first method determines a state, to be written to a blockchain ledger, based on a contract transaction. A second method determines a state, to be written to the blockchain ledger, based on an adapter transaction. The first method includes an invocation of the second method. The second method verifies whether the adapter transaction includes a particular set of information associated with a particular application. If the adapter transaction includes the particular set of information, then both the contract transaction and the adapter transaction are committed to the blockchain ledger. If the adapter transaction does not include the particular set of information, then neither the contract transaction nor the adapter transaction are committed to the blockchain ledger. The state determined based on the adapter transaction is used to update the particular application.
