Multi-blockchain cross-chain data processing method and system

Abstract

The invention discloses a multi-blockchain cross-chain data processing method and system, and the system comprises a main chain which comprises a main chain verification node, a main chain collector node, and a main chain observer node; multiple sub-chains with each sub-chain comprising a sub-chain verification node, a sub-chain collector node and a sub-chain observer node; wherein each main chainverification node is used for participating in main chain verification; the main chain collector node is used for receiving a sub-chain block proposal; wherein the main chain observer node is used for synchronizing a block state of a main chain, the sub-chain verification node is used for participating in consensus of the main chain and a related sub-chain, the sub-chain collector node is used for monitoring generation of a block and submitting a sub-chain block proposal to the main chain collector node, and the sub-chain observer node is used for synchronizing the block state of the sub-chain. The differentiated feature sub-chains are created for different services, higher-level consensus verification is carried out by means of main chains, the processing performance of block chains is improved on the premise that safety is ensure and diversified demands of services are met.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a multi-block chain cross-chain data processing method and system. Background technique [0002] Today's mainstream blockchain platforms such as Bitcoin and Ethereum are essentially single-chain systems. However, with the rapid increase in the number of blockchain users and transactions, the problems faced by the single-chain system have become increasingly prominent: [0003] 1. The consensus efficiency of the entire network of a single chain is limited by the scale of consensus nodes [0004] The ever-increasing transaction and data block information makes the blockchain increasingly bloated, and the parallel ability of block generation is insufficient. The existing Ethereum EVM, etc. need to execute and process transactions sequentially. At the same time, for security and decentralization considerations, each full node will execute each transaction and store the entire ...

AI Technical Summary

Problems solved by technology

However, Ethereum co-founder Vitalik Buterin said that it may take 2 to 5 years to fully scale Ethereum using sharding technology

[0005] 2. The single-chain network-wide backup mechanism reduces storage efficiency

With so many active users requesting multiple transactions per day, this puts a heavy load on the Ethereum network, and many transactions that previously took seconds are delayed to 10 minutes, or fail entirely

[0007] 3. The single-chain system cannot meet the diverse demands of the business

The first simple solution is to abandon the expansion of a single blockchain, and users use many different similar blockchains, which can achieve the purpose of improving throughput, but the security is reduced

The second solution is to increase the block size, which is familiar to everyone. The main problem is to increase the processing pressure of user nodes, which will cause many individual users to give up verification, which may cause greater risk of centralization

The third solution is joint mining, which can have many chains, but these chains share the same mining resources and capabilities, which actually increases the pressure on miners
