Description
Technical Field
The invention belongs to the technical field of block chains, and particularly relates to a multilayer cross-chain operation method, a multilayer cross-chain operation system and multilayer cross-chain operation equipment with a root chain-branch chain structure.
Background
The block chain utilizes a distributed storage technology, data are recorded by using a cryptography method, and the data recorded on the chain cannot be modified, so that the block chain has the advantages of cryptography safety, no tampering and the like. The method is widely applied to various fields such as finance, energy, retail, government affairs, authentication and the like.
With the development of the blockchain technology, more blockchain use scenarios are provided, each use scenario deploys one or more blockchains, and data structures and technical architectures used by the blockchains are different. Due to the complex diversity of service scenes, data structures and technical frameworks, data on the chains of the heterogeneous multi-sample block chains cannot be communicated with each other, a data isolated island is formed, and the value of the data cannot be exerted.
The cross-chain technology realizes the communication and interaction between chains of different users and different scenes by using the technologies of credible verification, network communication and the like, solves the problem of data and information isolated island, greatly promotes the circulation and transfer of data elements, and exerts the value of data and information to the greatest extent.
The existing chain crossing method realizes the interaction between chains, but has the following defects:
1. the security and credibility of the cross-chain method still need to be improved, for example, the notary technology realizes data circulation and interaction between different block chains by means of a third-party notary (for example, a certain group or organization), but the third-party notary may also be malicious or attacked, which brings potential safety hazards to cross-chain operation; 2. the existing chain crossing method is lack of top-level design and management on a chain crossing network structure, has the problems of unbalanced load and low expandability, is difficult to support a large-scale hierarchical complex chain crossing scene, and is also lack of effective supervision and management on chain crossing behavior records; 3. the existing multilayer cross-link method usually adopts a point-to-point network addressing or a step-by-step reporting and step-by-step circulation technology, has the problems of long addressing time and long cross-link transaction links, and each needs multilayer verification, thereby causing the performance of the whole cross-link system to be lower.
Patent document CN114301912A discloses a method and an apparatus for information interaction based on a blockchain, where the method is performed by a node of a first blockchain, and the method includes: receiving a cross-link service request; responding to the cross-chain service request, and executing a cross-chain task corresponding to the cross-chain service request; identifying and confirming the cross-chain information related to the cross-chain service request; sending the cross-link information to a node on a second blockchain, so that the node on the second blockchain executes cross-link operation according to the cross-link information; receiving results of the execution of the cross-chain operation from nodes on the second blockchain. The method discloses a principle of direct cross-chain operation, but the method has the problems of unbalanced load and low expandability, and is difficult to support a large-scale hierarchical complex cross-chain scene.
Patent document CN115080994A discloses a block chain cross-chain gateway data interaction method based on time locking and middleboxes, which includes steps 1: the cross-link gateway is accessed into a service chain, then the cross-link gateway configures port information of the service chain and configures a cross-link gateway management account on the accessed service chain; and 2, step: the cross-chain gateway registers on the cross-chain operation consensus chain, and accesses the cross-chain operation consensus chain after the registration is successful; and 3, step 3: entering an initial monitoring state by the cross-link gateway, and monitoring user operation, wherein the user operation comprises local service link data interaction, cross-link data query and cross-link data update; and 4, step 4: the cross-link gateway records a cross-link operation log in real time, monitors a cross-link transaction request port and simultaneously performs service distribution according to the request; and 5: after the cross-chain gateway completes the cross-chain transaction, the cross-chain operation consensus chain stores the cross-chain network attention book information, the cross-chain gateway releases account control and then ends the monitoring state, and the cross-chain gateway data interaction method based on the time locking and the operation central station block chain is completed. According to the method, the cross-chain operation is realized through the cross-chain consensus chain, and a new relay chain needs to be introduced into the traditional block chain structure, so that the load requirement of a block chain system is increased.
