Embodiment Construction

[0054] The present invention is described in further detail now in conjunction with accompanying drawing.

[0055] A blockchain-based non-trusted node cooperation method and system, the overall idea is as follows figure 1 As shown, the nodes participating in the public chain may have insufficient computing resources. At this time, servers are arranged at the edge of the system. The public chain nodes can purchase computing resources from the edge server computing center and offload computing tasks to the edge server. And when the funds of a single node are not enough to purchase computing power, the node will choose the cooperation mode, and several nodes that want to cooperate will be connected in the form of alliance chain, and the master node will be selected in turn. The nodes on the chain broadcast the funds and reputation values ​​they can provide, and the master node selects the nodes that realize the consensus process and completes the PBFT consensus, preventing too ma...

Abstract

The invention discloses a non-trusted node cooperation system based on a block chain, and the system comprises a public chain module which is used for downloading block information to a main node, receiving a calculated block uploaded by the main node, and issuing an award to each node in proportion according to a contribution record; according to the alliance chain cooperation protection module, several nodes cooperating in the public chain realize connection and consensus in an alliance chain form, and after the block is successfully linked, the alliance chain nodes receive rewards issued by the public chain platform according to a proportion; and the edge server computing module is arranged at the edge of the system, consists of a plurality of servers with high computing resources, and is responsible for selling the computing resources to the nodes, undertaking an unloaded computing task, assisting a public chain node consensus chaining process and playing a role in assisting lightweight nodes to join the block chain. According to the non-trusted node cooperation system based on the block chain, cooperation among the non-trusted nodes is realized through the alliance chain, and the problems of ditrust among the nodes, collusion possibly existing among part of the nodes and the like are avoided.

Description

technical field [0001] The invention relates to a blockchain-based non-trusted node cooperation method and system, belonging to the technical field of blockchain. Background technique [0002] Blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, traceability throughout the process, traceability, collective maintenance, and openness and transparency. The consensus mechanism is the key technology to ensure the consistency of distributed nodes. For the public chain system, the most commonly used proof of work mechanism (Proof of work, POW) is to use the one-way irreversible characteristic of the Hash function, and the node that first calculates the random number less than a specific difficulty through computing power competition obtains the right to bookkeeping. This ensures the consistency of each node in the blockchain system. [0003] The proof-of-work mechanism usually requires a large amount of computin...
