Description

This disclosure relates to transaction processing in a blockchain system for improving processing and resource utilization efficiency. Blockchains are used within various decentralized systems and can provide a ledger of transactions that occur within these systems. Generally, a blockchain may contain a chain of blocks, where the most recent block contains some information about the transaction that occurred and a reference value to the preceding block, which may be the hash value of the previous block. Since the reference value to the preceding block can be a value derived from the preceding block, transaction verification within the blockchain can be performed by ensuring that the hash of the block results in the same value as the reference value to the preceding block stored in subsequent blocks within the blockchain. If there is a mismatch between the calculated hash of a block and the hash value of the block in subsequent blocks within the blockchain, blockchain verification may fail. In some cases, transactions may be recorded on multiple blockchains. For example, a transaction may be first recorded on a first blockchain and then transferred or "bridged" to a second blockchain. Generally, the process of recording a transaction on a first blockchain and bridging this transaction to a second blockchain may be performed as a series of asynchronous, independent transactions involving multiple parties. Bridging a transaction from a first blockchain to a second blockchain generally involves multiple independent transactions, which can increase the overall processing cost of bridging the transaction and the risk of transaction failure. For example, a transaction may be partially completed, leading to an inconsistent state in the system (e.g., the first blockchain contains a record of the transaction, but the second blockchain does not contain the corresponding record or only contains a partial record that does not complete the bridging process). Furthermore, the use of multiple independent transactions may require coordination between different parties to complete the transaction, which can impose significant processing overhead when generating and processing overhead messages within the blockchain system. Therefore, techniques are needed to enable the efficient processing of transactions bridged across multiple blockchains. Several embodiments provide a computer implementation method for bridging transactions between blockchains. This method generally includes receiving a request to invoke an atomic transaction, which includes an action performed on a first blockchain and an action performed on a second blockchain. Generally, an atomic transaction completes when the enumerated set of actions is completed. A first action relating to the atomic transaction within the enumerated set of actions is initiated on the first blockchain. Initiating the first action on the first blockchain triggers the initiation of one or more second actions relating to the atomic transaction on the second blockchain. Completion of one or more second actions relating to the atomic transaction on the second blockchain is detected, indicating that the actions for the atomic transaction related to the second blockchain have been completed on the second blockchain. Based on the detection of the completion of one or more second actions on the second blockchain, the atomic transaction on the first blockchain is confirmed. Other embodiments provide a processing system configured to perform the methods described above and the methods described herein; a non-temporary computer-readable medium containing instructions that, when executed by one or more processors of the processing system, cause the processing system to perform the methods described above and the methods described herein; a computer program product embodied on a computer-readable storage medium containing code for performing the methods described above and the methods further described herein; and a processing system comprising means for performing the methods described above and the methods further described herein.
