Problems solved by technology

However, the current time stamp benchmark is based on the system time of the node, and there is no unified time benchmark. With the expansion of the blockchain application field, the time information and location information of each transaction should also be used as a necessary properties, however, the existing blockchain nodes do not have a unified source of time information and location information

Abstract

The invention discloses a spatiotemporal credible block chain generation method. A node sends an authentication request to a CA authentication center, and the CA authentication center authenticates the time and space of the node respectively, and the node after both authentications are successful can join In the blockchain system; when a node generates blockchain transaction information, the time and location information of the node is added to the transaction information; the transaction information is included in the transaction block of the current bookkeeping cycle; The transaction information in the block is calculated, and the time information of the bookkeeping node is used as a time stamp, and the location information is added to the transaction block as a position stamp. The invention provides a unified time and space reference for the blockchain system, records the time information and location information of each transaction as necessary attributes in the transaction information, and uses the time information and location information of the accounting nodes as timestamps respectively and location stamps are recorded in transaction blocks.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a spatiotemporal credible block chain generation method and equipment. Background technique [0002] Blockchain is one of the most revolutionary emerging technologies at present. It is a combined technology that integrates P2P dynamic networking, cryptography, consensus mechanism and other technologies. Due to its characteristics of decentralization, distributed storage, traceability, and non-tampering, its application fields are increasing, such as the financial field, government supervision field, and the Internet of Things field. [0003] The blockchain is a chain based on blocks, and each block is included in the chain by the nodes in the chain according to the consensus mechanism. The core of the block is that there is no mutual control between each node without central control. Under the premise of trust, it operates completely according to the consensus mechanism. E...
