Problems solved by technology

[0003] In the consortium chain, nodes in the consortium chain can use the local time system to stamp time stamps on blocks or transactions, but the consortium chain lacks a global clock, and furthermore, each node in the consortium chain lacks a time reference, making it impossible to judge Accuracy of timestamped information in blocks or transactions

Embodiment Construction

[0069] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0070] The embodiment of the present invention provides a global clock system of alliance chain, refer to figure 1 , including a global clock node, an endorsement node, an ordering node, and a verification node; there are at least three clock sources used in the global clock node, the endorsement node, the ordering node, and the verification node.

[0071] In order to meet the security and high concurrency requirements of commercial use, on the basis of the pu...

Abstract

The invention provides a global clock system and method of an alliance chain. The objective of the invention is to solve problems of application and popularization of a block chain technology in time-sensitive business scenes. According to the embodiment of the invention, on the basis that typical alliance chain model pre-selected nodes are divided into three types of nodes according to endorsement, sorting and verification, global clock nodes are added, and the global clock nodes can select a Byzantine fault-tolerant algorithm according to the number of time sources to ensure the stability ofclock services. Besides, the embodiment of the invention also perfects confirmation of timestamp information in a consensus mechanism through a set of strict global clock system and method, and realizes strong consistency of node consensus time. That is to say, based on the global clock service, the accuracy of time synchronization of endorsement nodes, sorting nodes and verification nodes in thealliance chain model is ensured, the block or the transaction is stamped with the timestamp only when the time synchronization is accurate, and the accuracy of stamped timestamp information in the block or the transaction is ensured.

Description

technical field [0001] The present invention relates to the field of global clock and clock synchronization of the special distributed system of consortium chain, and more specifically, relates to a global clock system and method of consortium chain. Background technique [0002] The consortium chain is a blockchain that requires registration and permission. It is limited to the participation of consortium members. Nodes need to be fully authorized before they can access the system. [0003] In the consortium chain, nodes in the consortium chain can use the local time system to stamp time stamps on blocks or transactions, but the consortium chain lacks a global clock, and furthermore, each node in the consortium chain lacks a time reference, making it impossible to judge Accuracy of timestamped information in blocks or transactions. Contents of the invention [0004] In view of this, the present invention provides a global clock system and method of the consortium chain t...
