ODAP-2PC assures that gateways running ODAP are crash-fault tolerant, meaning that the atomicity of asset transfers are assured even if gateways crash. This protocol includes the description of the messaging and logging flow necessary for gateways to keep track of current state, the crash recovery protocol, and a rollback protocol.
