Problems solved by technology

[0005] It can be found that in the existing technology, the consensus nodes will perform consensus verification on all received blocks to be verified, and then chain the verified blocks into the corresponding forked chains, but when the long chain (main chain) is saved , after the short chain is abandoned, the computing power consumed to verify the blocks in the short chain is obviously wasted

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

[0032] In the existing technology, the consensus node receives block B N After that, for block B N Do consensus verification instead of checking block B first N Whether the forked chain to be linked is the main chain (long chain), if the state of each chain in the forked chain can be predicted after a certain time to determine the main chain, then the blocks that are not linked into the main c...

Abstract

The invention discloses a block transaction accounting method and system, a data processing terminal and a block chain system. The block transaction accounting method comprises the steps of receivingand temporarily storing a to-be-verified block; determining an accounting chain at the end of the delay period after the delay period; selecting to carry out transaction verification or discard on theto-be-verified block according to the accounting chain; and performing transaction accounting on the to-be-verified block passing the transaction verification. According to the block transaction accounting method provided by the invention, the transaction is executed in a delayed manner, when the to-be-verified block is received, the block is temporarily stored, and the to-be-verified block is verified or discarded according to the block chain bifurcation condition after a delay period is waited, so that the waste of the computing power of the consensus node is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to a transaction bookkeeping method and system for blocks by consensus nodes of a block chain network. Background technique [0002] The blockchain system is essentially a peer-to-peer (P2P, peer-to-peer) distributed ledger database system. The blockchain is a series of linked data blocks. Each data block records a set of tree-like transaction status information composed of a hash algorithm to ensure that the transaction data in each block cannot be tampered with. The blockchain The blocks linked in it cannot be tampered with. In the blockchain system, a block is generated in each block generation cycle, and the transaction records that occur in each block generation cycle are stored in the blocks generated in this block generation cycle. Blocks are generated through mining. The so-called "mining" is an exhaustive random algorithm. The nodes (miners) participating...
