A data processing method and device

Abstract

The invention discloses a data processing method and a device, used for increasing the data preservation efficiency and reducing the data preservation cost. The method comprises the following steps: receiving to-be-preserved data sent by a target user; calculating a hash value corresponding to the to-be-preserved data; storing the hash value corresponding to the to-be-preserved data into a target data block; judging whether the target data block meets a preset requirement; constructing a target binary tree according to a target hash value if the target data block meets the preset requirement; calculating the hash value of a root node of the target binary tree; and storing the hash value of the root node of the target binary tree in a target block chain for performing virtual currency transaction. According to the method provided by the invention, the batch preservation of the to-be-preserved data can be realized, the data preservation efficiency is increased and the data preservation cost is lowered.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a data processing method and device. Background technique [0002] Blockchain refers to a technical solution for collectively maintaining a reliable database through decentralization and trustlessness. This technical solution mainly allows any number of nodes in the participating system to associate a series of data blocks generated using cryptographic methods. Each data block contains all information exchange data of the system within a certain period of time, and generates data fingerprints. to verify the validity of its information and link to the next database block. [0003] Since the data stored in the blockchain is not easy to be lost and tampered with, it plays an important role in the fields of data security and data notarization. When performing data preservation, the hash value corresponding to the data is stored in the blockchain, and after the transaction is c...

[0004] However, the transaction confirmation cycle in the blockchain is long. When there are multiple pieces of data that need to be preserved, after the hash value corresponding to each piece of data is stored in the blockchain, it needs to wait for a long time to ensure the hash value. The value where the transaction has been confirmed a sufficient number of times, therefore, the preservation efficiency is low
