Expandable-subchain system architecture with main chain and multiple parallel subchains

Abstract

The invention provides an expandable-subchain system architecture with a main chain and multiple parallel subchains, which comprises a main chain and multiple parallel subchains. Each node stores mainchain data and is initially allocated by the system with all data of a subchain; the main chain data are provided with the minimum node number and the maximum node number, effect is taken when the node number corresponding to the subchains is no smaller than the minimum node number, the subchain node number does not exceed the maximum node number, and whether a subchain takes effect is also contained in the main chain data; in the case of node registration, a registration request is submitted to a main chain system contract, the system judges whether a subchain with the node number smaller than the maximum node number exists, if yes, the nodes are allocated to a subchain with the minimum node number, or otherwise, a new subchain is expanded, and the subchain does not take effect; and after node registration, the node number of a corresponding subchain is firstly no smaller than the minimum node number, the new subchain takes effect, the subchain number and the system capability are expanded dynamically, and the more the participating nodes are and the more the subchains are, the stronger the system capability is.

Description

technical field [0001] The present invention relates to block chain technology, and in particular proposes a system architecture of a main chain plus parallel multi-sub-chains, especially a system architecture of a main chain with expandable sub-chains and parallel multi-sub-chains, which improves the performance of the block chain. Scalability and performance. Background technique [0002] Every ordinary node in the blockchain now: 1. Store all states; 2. Execute all transactions serially; 3. Reach consensus with all other machines. [0003] The basic idea for the extension of the existing blockchain is: 1. A single node only stores part of the state; 2. A single node only processes part of the transaction; 3. Only some nodes participate in the consensus. [0004] see figure 1 As shown in , it is a schematic diagram of sharding by user. If it is sharded by user, it is difficult to handle transfers between users in different shards, and it is also difficult to deploy cont...

AI Technical Summary

Problems solved by technology

[0014] To sum up, scalability is still a difficult point at present. Expansion through sharding and multi-chain is a basic solution, but the key question is how to do sharding? How to make multiple chains appear as one chain to the outside world? How to maintain low cross-chain overhead and achieve linear expansion under the premise of ensuring security? This is also the problem to be studied and solved in the present invention
