Problems solved by technology

[0002] At present, there are two main types of cross-level blockchain cross-chain technologies: hash locking mechanism and relay chain technology and relay chain two-layer network expansion technology. Among them, hash locking technology is limited to cross-level asset classes. The operation between blockchains cannot be extended to the operation of general smart contracts, and although the cross-chain transactions of heterogeneous blockchains are realized, in essence, each heterogeneous chain is transformed into a relay chain through bridging technology. The isomorphic chain of verification rules; and the two-layer network expansion technology of the relay chain, the cross-level transmission of transactions may experience multiple jumps of the relay chain, and the operation of the relay chain requires a series of operations such as consensus, and the speed is relatively slower and much less efficient

Embodiment Construction

[0060] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain related inventions, rather than to limit the invention. It should also be noted that, for ease of description, only parts related to the invention are shown in the drawings.

[0061] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0062] The first relay chain is the relay chain registered by the source chain in the cross-chain transaction sent, and the second relay chain is the relay chain registered by the destination chain in the cross-chain transaction. The source chain and the destination chain can be registered on the ...

Abstract

The invention provides a cross-chain method for blockchain transaction, and the method comprises the steps: receiving first cross-chain transaction request information sent by a source chain, whereinthe first cross-chain transaction request information comprises the transaction information of a first cross-chain transaction; after verifying that the first cross-chain transaction is credible, judging whether a destination chain receiving the cross-chain transaction is located on the first relay chain or not; if so, sending the first cross-chain transaction to the destination chain to completethe first cross-chain transaction; and if not, sending the first cross-chain transaction to the corresponding first cross-chain gateway so that the first cross-chain gateway finds the second relay chain and sends the first cross-chain transaction to the destination chain to complete the first cross-chain transaction. By setting a plurality of cross-chain gateways, rapid acquisition and response between relay chains are realized, and on the other hand, cross-chain transactions between contracts can be carried out by application chains with different verification rules on each relay chain, so that real cross-level cross-chain transactions between heterogeneous chains are realized.
