Embodiment Construction

[0029] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0030] refer to figure 1 , figure 1 It is a flowchart of steps of a method for storing block data provided in an embodiment of the present invention. The method can be executed by a block chain node, and the block chain node includes electronic devices such as computers and servers. The method comprises the steps of:

[0031] Step 101. Obtain the current block data and calculate the block hash value of the current block data.

[0032] Since each block data includes block header data and block body data, the block header data usually includes the block version number, the block hash value of the previous current block data of the current block data, the The root node hash value of the Merkle tree of the current block data, the timestamp, the current difficulty target hash value of the current block d...

Abstract

The embodiment of the invention provides a current block data storage method and device, electronic equipment and a readable storage medium, and the method comprises the steps: obtaining the current block data, calculating the block hash value of the current block data, mapping the block hash value to a pre-constructed hash ring, and storing the pre-constructed hash ring in a database, determiningthe first position by mapping the public key value of the block chain node to the hash ring, and determining a distance between the first position and the second position, wherein the second positionis determined by mapping the public key value of the block chain node to the hash ring and is the position corresponding to the block chain node on the hash ring; if the distance between the first position and the second position is smaller than or equal to a preset threshold value, storing the current block data, wherein the preset threshold value is determined according to an expected proportion and the perimeter of the hash ring, and the expected proportion is the proportion of the block data stored on each node in the expected block chain network to all block data on the block chain; andthe data storage pressure of the blockchain node is reduced to a certain extent.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a block data storage method, device, electronic equipment and readable storage medium. Background technique [0002] The blockchain is a chained data structure that combines the current block data in a sequentially connected manner in chronological order, and is a cryptographically guaranteed non-tamperable and unforgeable distributed ledger. The blockchain storage mode is a decentralized storage based on the blockchain, and each node in the blockchain network contains blockchain data on the blockchain. Due to the increasing number of transactions on the blockchain over time, the current block data on the blockchain continues to increase, and it becomes increasingly difficult for a single node to carry blockchain data. [0003] In the virtual currency ecosystem, most of them are ordinary users. If the terminal devices of ordinary users also need to store blockchain dat...
