Patent attributes
A method of synchronizing transactions between blockchains comprising receiving first and second pluralities of transactions on a first private blockchain network and recording them to first and second private blocks on the first private blockchain network, respectively, generating a first merged block comprising the first private block and the second private block and recording the first merged block to a single block on a second blockchain network, recording each of the first and second private blocks and the first merged block to a first private smart contract linked to the first private blockchain network, performing a synchronization process between the first private smart contract and a second smart contract linked to the second blockchain network, defining a second smart contract, and performing a checkpointing process between the first private smart contract and the second smart contract. The first private blockchain network has a parameter difference from the second blockchain network.
