If the consensus mechanism is the soul core of the blockchain, the cross-chain technology is the key for realizing the value network for the blockchain, particularly the alliance chain and the private chain, the cross-chain technology is a good drug for saving the alliance chain from a dispersed single island, and the cross-chain technology is a bridge for outwards expanding and connecting the blockchain. The cross-chain technology is a technology for realizing interconnection and intercommunication among block chains. In the problems faced by the block chain, the application space of the block chain is limited to a great extent by the interoperability between the block chains, high isomerization exists between the block chain chains, each single block chain network is a relatively independent network, the data information cannot be intercommunicated and interconnected, and the information island problem exists. The cross-chain technology is to connect homogeneous or heterogeneous block chain systems to realize the operation of assets and data. The chain crossing technology is the key for realizing the value internet, is a good medicine for saving the block chain from a dispersed isolated island, and is a bridge for outwards expanding and connecting the block chain. Early cross-link technologies are represented by rayleigh and BTC Relay, and are more concerned about the transfer of assets; the existing chain-crossing technology is represented by Polkadot, Cosmos and Aion, and mainly focuses on building a chain-crossing infrastructure. The emerging FUSION realizes a multi-currency intelligent contract, is a public chain with high application value, and can generate rich cross-chain financial application. After confirmation through the message intercommunication mechanism, the same number of mapping assets with the same value, such as 10 ETH' are generated on the new chain, so that the free flow of the assets on different chains is realized. And the same step is also carried out in the asset reflow, and after the mapping assets on the new chain are destroyed, the locked assets on the original chain are unlocked and transferred to the user to be transferred.
When cross-chain data synchronous interaction is carried out on the existing block chain, data interaction is carried out while transaction data are generated, the storage capacity of the block chain is small, massive data information service cannot be supported, the transaction flow of the block chain in the cross-chain process is complex, the time is increased, and the user experience is poor.

if the second judgment result is yes, the verification is passed, otherwise, the verification is not passed.
7. A blockchain cross-chain system comprises at least two blockchains, and is characterized in that any two blockchains in the system interact with cross-chain data by using a blockchain cross-chain data interaction method.
8. The blockchain inter-chain system of claim 6, wherein the blockchain inter-chain system further comprises a database for storing the blockchain inter-chain data interaction method.
9. The system of claim 6, wherein the blockchain in the system comprises a memory and a processor, the memory and the processor being electrically connected, the memory being configured to store program data, and the processor being configured to control and execute the application program stored in the memory.
10. A blockchain cross-chain storage medium, wherein the storage medium is a computer program, the computer program readable storage medium includes blockchain cross-chain data, and when the blockchain cross-chain data is executed by a processor, the blockchain cross-chain data interaction and verification method of any one of claims 1 to 5 is implemented.
