Consensus device and method for file block chain based on contribution value proof

Abstract

The invention discloses a consensus device and a consensus method for a file block chain based on contribution value proof. The consensus device comprises an in-chain initialization module, an information collection module, a main node selection module, a packaging in-chain module and a file management module. The consensus device is used for realizing the consensus method, ensuring the file chaining efficiency when the block chain technology is used in the file management field, and ensuring the integrity and the security of the file block at the same time. When an existing virtual currency consensus mechanism is transplanted to the field of file management, a contribution value proof-based method is designed, and the size of a block, the transmission pressure of nodes, the communication bandwidth, the storage amount, the performance, the historical performance and the like serve as calculation factors for calculating contribution values; when the main bookkeeping node is selected, the main bookkeeping node meeting the requirements of all the factors is fully considered and elected, so that the file uplink efficiency in the file management field is met, and meanwhile, the completeness and safety of file blocks are ensured.

Description

technical field [0001] The invention belongs to the technical field of blockchain application, and in particular relates to a consensus device and a consensus method based on contribution value proof for file blockchain. Background technique [0002] Blockchain technology has continued to develop in recent years. Its essence is a shared database that stores data information or transaction records. It has the characteristics of traceability, non-tampering, openness and transparency, and is widely used in medical, education, finance and other fields. [0003] The consensus mechanism is the core of the blockchain. By establishing a series of rules, multiple unrelated parties can confirm or reach an agreement on transactions. The consensus mechanism in the blockchain mainly studies the distribution of bookkeeping rights and the confirmation of blocks. At present, the mainstream consensus mechanisms include POW, POS, DPOS, PBFT, etc. POW (Proof of Work) requires nodes to use co...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the existing consensus mechanism does not comprehensively consider the hardware performance, historical performance and contribution of the nodes, so that the elected master node may be a malicious node or cannot be completed due to insufficient communication, storage or performance capabilities. Consensus process, which leads to the problem that the system cannot run safely and stably, proposes a consensus device and consensus method based on proof of contribution value for the file block chain
