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 space-time credible block chain generation method, which comprises the following steps that: a node sends an authentication request to a CA (Certificate Authentication) center, the CA center authenticates the time and space of the node respectively, and the node after successful authentication of the time and space can be added into a block chain system; when the node generates block chain transaction information, time and position information of the node is added into the transaction information; wherein the transaction information is included in a transaction blockof a current accounting period; and the accounting node calculates the transaction information in the transaction block, and takes the time information of the accounting node as a timestamp and takesthe position information as a position stamp to be added into the transaction block. Unified time and space references are provided for a block chain system, time information and position informationof each transaction are recorded in transaction information as necessary attributes, and time information and position information of an accounting node are recorded in a transaction block as a timestamp and a position stamp respectively.

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...
