Description
Technical Field
The invention relates to the field of blockchain, in particular to an EOS blockchain super node architecture and an implementation method thereof.
Background
The intelligent contract has the advantages of higher transaction processing efficiency, non-reversibility, safe transaction and full-automatic flow, and has attracted extensive attention and developed rapidly in recent years. At present, the same node of an EOS block chain is responsible for both the block production task and the intelligent contract execution task, and the two functions are deployed on the same physical host. This architecture has four disadvantages:
1. with the explosive growth of future intelligent contracts, the storage and access of the intelligent contracts can exert great pressure on the memory resources of the nodes, and the transaction can be congested or delayed to be executed until the memory is exhausted, so that the risk of paralysis of the nodes exists.
2. The cost is high for expanding the memory resource of a super node.
3. Because the memory requirement is continuously increased, and the memory of a single node cannot be infinitely increased, a resource bottleneck exists.
4. A single node has limited computational power and cannot handle parallel execution of a large number of contracts.
How to solve and optimize the above disadvantages is a problem to be considered by the related technical personnel.

(4) and the block production module returns the result of the intelligent contract access request and related data to the external client, generates a corresponding block and stores the corresponding block in a block database of the block chain, so that the external client can access the intelligent contract.
Further, the resource information registered in the step (1) includes hardware resource data information, provided intelligent contract service information, and efficiency information of executing a contract in the past.
Further, the scheduling policy in step (2) includes an efficiency priority algorithm and a hash algorithm.
Furthermore, when the intelligent contract server quits, the intelligent contract server logs out through a logout interface of the contract scheduling module; when the intelligent contract server has hardware resource data information change and the provided intelligent contract service information change, the original information is updated through the updating interface of the contract scheduling module.
Further, the block production module uses the external network IP to be responsible for sending and receiving intelligent contract access requests to external clients, uses the internal IP to communicate with each intelligent contract server, and carries out requests and processing with each intelligent contract server through a high-quality local area network.
Further, the contract scheduling module periodically inquires information of an online intelligent contract server of the registration center ETCD, and when the online intelligent contract server is found to be changed, the information is synchronously changed into the local cache configuration of the intelligent contract server.
