Problems solved by technology

[0003] However, due to the inconsistency of the state between multiple blockchains, that is, the blockchain state, it usually occurs during operation, which leads to the failure of the blockchain system to operate normally, such as low data processing efficiency.

Abstract

The invention discloses a method and device for synchronizing a blockchain state based on trusted computing, and a related product. The method for synchronizing the blockchain state based on trusted computing comprises the following steps: calculating trusted values of a plurality of blockchain nodes based on a set trusted computing mechanism; verifying and voting the plurality of blockchain nodesaccording to the trusted values; sorting the trusted values of all the blockchain nodes passing the verification and voting to obtain a trusted value sequence; and according to a set state synchronization mechanism, performing state synchronization on the blockchain nodes corresponding to at least part of the trusted values in the trusted value sequence, thereby realizing state synchronization between the blockchains and ensuring normal operation of a blockchain system.

Description

technical field [0001] The present application relates to the technical field of blockchain, in particular to a method, device and related products for synchronizing blockchain state based on trusted computing. Background technique [0002] The blockchain system is essentially an integrated application model of distributed data storage system, point-to-point transmission, consensus mechanism, encryption algorithm and other technologies, which can realize trust and value transfer that cannot be realized on the traditional Internet on the Internet. It is based on the principle of cryptography rather than credit, so that any two parties who reach an agreement can directly trade without the participation of a third-party intermediary. On the other hand, there is almost no single point of failure in the blockchain. The data on the chain is stored on countless machine nodes around the world, making the data "stable", "credible" and "untamperable", which re-empowers the network A ...
