Problems solved by technology

[0003] In some blockchain designs, Domain Name System (DNS) or user names adopt the first-come-first-come principle, or transaction information needs to be recorded in chronological order, but since each participant can send messages, Moreover, it takes a certain amount of time for information to be transmitted in the network, so time confusion often occurs, which reduces the security of users using blockchain for transactions

Embodiment Construction

[0019] figure 1 It is a flowchart of the blockchain bookkeeping method provided by the embodiment of the present invention. The embodiment of the present invention provides a blockchain bookkeeping method aiming at the security of users using the blockchain for transactions. The specific steps of the blockchain bookkeeping method are as follows:

[0020] Step S101, the bookkeeping node receives the transaction information, and obtains the time stamp in the transaction information.

[0021] Such as figure 2 As shown, the blockchain network includes multiple nodes, and the blockchain network can specifically be a peer-to-peer network. Every time each node in the blockchain network receives a broadcast message, it obtains the time stamp in the broadcast message , and calculate the time difference between the time stamp in the broadcast message and the network standard time when the node receives the broadcast message, the time difference can be regarded as the transmission del...

Abstract

The embodiments of the present invention provide a method and an apparatus for Blockchain billing. The method includes: a billing node receives the transaction information and obtains a timestamp in the transaction information; and the billing node determines the validity of the transaction information or the previous block according to the timestamp, the issuing moment of the previous block, and the median value of the time information sent respectively by the various nodes in a Blockchain network contained in the previous block. According to the invention, based on the timestamp of the received transaction information, the issuing moment of the previous block and the median value of the time information sent respectively by the various nodes in a Blockchain network contained in the previous block, the validity of the transaction information or the previous block can be determined, which avoids the chaos or loss of account books caused by the chaos of time and avoids the deliberate concealment of transactions from hacker nodes. Therefore, transaction security using Blockchain can be ensured.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a blockchain accounting method and device. Background technique [0002] Blockchain (Blockchain) is an important concept of Bitcoin. Blockchain is a series of data blocks associated with cryptographic methods. Each data block contains the information of a Bitcoin network transaction, which is used to verify its Validity of information (anti-counterfeiting) and generation of the next block. In a narrow sense, the blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be tamper-proof and unforgeable distributed ledgers. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission a...
