Blockchain method and system based on storage proof

Abstract

The invention provides a blockchain method and system based on storage proof. The method comprises the following steps: a storage data generation step: each new miner newly joining a network generatesdata needing to be stored by using the new miner; and a spatial declaration transaction broadcasting step: the new miner newly joining the network generates a Merkel commitment according to the stored data, the new miner regenerates and broadcasts a spatial declaration transaction, and the size of a hard disk space put into the new miner and the Merkel commitment for the stored data are declaredto the whole network. The invention provides a blockchain scheme based on storage proof. The problems existing in conventional block chain schemes based on PoW, PoS and the like are effectively solved, through ingenious design of a reasonable block scoring function, the probability that a miner successfully excavates a legal block is in direct proportion to the space size of a hard disk into whichthe miner inputs, and therefore competition fairness of the miner is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain method and system based on proof of storage. Background technique [0002] Blockchain technology is a decentralized chain ledger technology. It is based on cryptography technology and through a distributed consensus mechanism to achieve a complete and non-tamperable cutting-edge technology for value transfer. It is a distributed data storage, Point-to-point transmission, consensus mechanism, encryption technology, smart contract, economic game and other technologies are integrated and innovative technologies in the Internet era. From the central bank's attention to blockchain technology, to the white paper of the Ministry of Industry and Information Technology, to the official writing of the national informatization plan, the government is increasingly valuing and affirming the value of blockchain. Blockchain technology is expected to stimulate disrupt...

Problems solved by technology

However, the existing proof-of-stake-based blockchain solutions are relatively complex. For example, Algorand requires some token holders to run some complex Byzantine consensus protocol.

In addition, there is also a problem similar to the aggregation of computing power in the blockchain based on proof of equity. Since the block rewards obtained by miners are proportional to the current number of tokens, with the development of the blockchain, most of the tokens will be concentrated in In the hands of a few people, the resulting security issues will greatly limit the development of the blockchain
