Embodiment Construction

[0065] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0066] The present invention provides a blockchain-based decentralized data transaction method. In an embodiment of the blockchain-based decentralized data transaction method, refer to figure 1 , the decentralized data transaction method based on block chain includes:

[0067] Step S10, when the first transaction sub-data of the data transaction is received based on the preset block chain, select the first target shard from each preset shard of the preset network, and distribute the first transaction sub-data to The first target sharding process, wherein each preset shard of the preset network is obtained based on a preset first proof-of-work puzzle;

[0068] Step S20, when receiving the second transaction sub-data of the data transaction based on the preset block chain, select a second target shard from each shard o...

Abstract

The invention discloses a decentralized data transaction method and device based on a block chain, equipment and a medium. The method comprises the steps of when first transaction sub-data is receivedbased on a preset block link, selecting a first target fragment from all preset fragments of a preset network, allocating the first transaction sub-data to the first target fragment for processing, and acquiring all preset fragments based on a preset first workload proof puzzle; when second transaction sub-data of the data transaction is received, selecting a second target fragment, and allocating the second transaction sub-data to the second target fragment for processing; and obtaining target storage data of a seller blockchain user to which the first transaction sub-data and the second transaction sub-data point, and sending the target storage data to a buyer blockchain user to which the first transaction sub-data and the second transaction sub-data point. According to the invention, the technical problem of low transaction efficiency of the existing data transaction based on the blockchain is solved.

Description

technical field [0001] The present invention relates to the technical field of block chain, in particular to a decentralized data transaction method, device, equipment and medium based on block chain. Background technique [0002] Blockchain technology has been applied in digital currency such as Bitcoin, distributed ledger and other fields, but in the process of large-scale data transactions, the transaction speed of data transactions based on blockchain technology is limited, specifically, block The efficiency of the consensus mechanism of the chain determines the speed of the transaction, and the existing blockchain technology consensus mechanism needs to rely on each consensus node in the entire network to achieve a credible and unique block record, and relies on each consensus node in the entire network It will reduce the consensus efficiency, and then reduce the transaction efficiency of the entire data transaction. Contents of the invention [0003] The main purpos...
