Problems solved by technology
[0005] At present, in terms of solving the interconnection between blockchains, it is mainly reflected in the exchange of virtual assets of different blockchain networks. The main means are mainly based on centralized third-party platforms. The problems solved are limited and do not conform to Decentralized features of blockchain

Embodiment Construction
[0025] In the following, taking the Ethereum that supports smart contracts as the basis for building side chains as an example, how to realize the interconnection method and system between blockchain networks is explained.
[0026] In the Ethereum network, a blockchain network interconnection smart contract is deployed, the main contents of which include:
[0027]
[0028]
[0029] When creating a side chain, register its ID number, side chain subnetwork name, side chain static node list file stored in the distributed decentralized network IPFS in the hash link in the interconnected smart contract, and the side chain client software stored in IPFS hash link.
[0030] When the client accesses the side chain, it needs to go through the following steps:
[0031] First, the client software provides an interface for accessing interconnected smart contracts, and users get a list of all side chains when using this function;
[0032] Second, the user chooses to access the corr...

Aiming at a plurality of different types of block chain networks appearing at present, various block chain networks are continuously newly built due to the limitation of the transaction capacity of the block chain networks, so that the number is sharply increased, and popularization of block chain applications and use of common users are more and more difficult due to closure of the block chain networks. According to the system, a block chain interconnection smart contract is arranged in a block chain network supporting the smart contract and used for storing the key data of the block chains needing to be interconnected, the node can be freely switched to the corresponding block chain network to perform data synchronization, mining or data interaction after synchronizing that the node accesses the smart contract, and meanwhile, the cross-chain transaction is realized through the mapping relationship constructed by the key data between different chains. Through a decentralization mechanism of the system, the openness and the interconnection of the block chain network are ensured, and different block chain networks are constructed according to different application types, so that thehigh concurrency and the large user quantity support performance of the block chain network are obviously improved. Interconnection and intercommunication of the public chain, the alliance chain andthe private chain are realized.
Description
technical field [0001] The invention relates to the technical field of block chains, in particular to the field of interconnection between block chain networks. Background technique [0002] Currently, blockchain technology is in development, and blockchain networks with different technical mechanisms, user groups, and application fields are beginning to emerge. Each blockchain network actually has a different number of users, but these blockchain networks Due to the differences in data structures, consensus mechanisms, incentive mechanisms, and upper-layer application interfaces between networks, it is difficult to communicate between blockchain networks. Due to the division of the technical system between such blockchain networks, the scope of application of a single blockchain network is greatly limited, and it is difficult for ordinary users to choose, especially for users who need to use multiple blockchain networks at the same time. In other words, the trouble is even...
