Embodiment Construction

[0084] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0085] Aiming at the technical problem of the present invention, the embodiment of the present invention proposes a trusted processing method oriented to data transactions, which is applied to a P2P network system. The P2P network system includes a plurality of nodes, and the method includes a deposit method and a query method ;

[0086]In traditional deposit methods, credible deposit certificates are often associated with the difficulty of tamper-proof. The traditional so-called tamper-proof blockchain is not 100% guaranteed to be tamper-proof. For example, due to a loophole in the smart contract of Ethereum, hackers stole about 50 million dollars worth of Ethereum (the Ethereum at this time was not the current Ethereum), and Vi...

Abstract

The invention provides a data transaction-oriented trusted processing method and system, which are applied to a P2P network system, and the P2P network system comprises a plurality of nodes; the trusted processing method comprises a storage method and a query method, firstly, a directed acyclic graph account book structure is adopted in the storage process to be matched with an nRW consensus mechanism, and the supervision problem in the large-scale sharing exchange process is solved; secondly, in the query process, a P2P network system is optimized by maintaining a tree structure with high fault tolerance and load balance and adopting a hop count optimization method to construct the P2P network system with a relatively balanced network, so that the query delay is not greatly influenced onthe premise of ensuring the load balance, and the expandability of the system is ensured; and a delay optimization and neighbor node management protocol method is adopted, so that the query message can be received by the lower-layer node under the condition that the upper-layer node is down, and the node leaving the network can be dynamically replaced by a new online node.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a trusted processing method for data transactions and a trusted processing system for data transactions. Background technique [0002] Data resources are the core force driving the development of the digital economy and a key element in improving the intelligence level and operating efficiency of the information society, and are regarded as strategic assets that determine future competitiveness. How to capitalize the huge data resources formed during the operation of governments, enterprises and institutions, and make them the "new oil" that supports the rise of the digital economy is a key challenge for the development of the digital economy. The value of data assets is a process of "moving" the data. The safe and reliable flow, processing and integration of high-quality, high-availability, and high-efficiency data assets is an important basis for supporting big data analy...
