Problems solved by technology

[0003] If two different mining nodes grab the accounting right of the same transaction information, the two different mining nodes can record the same transaction information in different blocks, and record the same transaction information in different blocks Broadcast to the blockchain network, causing the same bitcoin to take effect in two transactions, the so-called double-spend attack, which reduces the security of the blockchain network

Abstract

Embodiments of the present invention provide a block processing method, device, and block chain node. The method includes: the block chain node receives a second block within a preset time after receiving the first block, and the identification information of the first block is the same as the identification information of the second block, so the identification information of the first block is the same as that of the second block. The first block includes a first timestamp, and the second block includes a second timestamp; if the first timestamp is less than the second timestamp, the blockchain node determines the first timestamp The block is valid; if the second time stamp is less than the first time stamp, the blockchain node determines that the second block is valid; wherein the first time stamp is when the time stamp server receives all the When the first hash value corresponding to the first block is selected, it is determined according to the reception time of the first hash value. The embodiment of the present invention ensures that the blockchain does not fork, thereby effectively avoiding double-spending attacks and improving the security of the blockchain network.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a block processing method, device and block chain node. Background technique [0002] In the blockchain network, when a mining node grabs the accounting right of a certain transaction information, the mining node can record the transaction information into a block and broadcast the block to the blockchain network . [0003] If two different mining nodes grab the accounting right of the same transaction information, the two different mining nodes can record the same transaction information in different blocks, and record the same transaction information in different blocks Broadcasting to the blockchain network causes the same bitcoin to take effect in two transactions, which is the so-called double-spend attack, which reduces the security of the blockchain network. Contents of the invention [0004] Embodiments of the present invention pro...
