Cross-chain data access device and system supporting supervision

Abstract

The invention discloses a supervision-supporting cross-chain data access device and system. The supervision-supporting cross-chain data access device comprises a first cross-chain gateway and a second cross-chain gateway, wherein the first cross-chain gateway is used for mutually converting an interface protocol of the connected alliance chain and a universal inter-chain communication protocol corresponding to the cross-chain gateway bus so as to realize data access among the alliance chains; and the second cross-chain gateway is used for mutually converting an interface protocol of the connected supervision system and a general inter-chain communication protocol, so that each supervision system can access and supervise the data of each alliance chain by means of the first cross-chain gateway. According to the application, under the establishment of the first cross-chain gateway, even if each alliance chain is based on different underlying technology platforms, data access between the alliance chains can be realized; under the establishment of the second cross-chain gateway, the second cross-chain gateway is matched with the first cross-chain gateway, so that each supervision system can access and supervise the data of each alliance chain, risks existing in the alliance chains can be found in time, and healthy development of the alliance chains is facilitated.

Description

technical field [0001] The invention relates to the technical field of consortium chains, in particular to a supervision-supporting cross-chain data access device and system. Background technique [0002] With the rapid development of alliance chain technology, alliance chain is widely used in many fields such as finance, law, and medical treatment. A consortium chain refers to a blockchain that is jointly managed by several institutions or organizations. The data in the consortium chain nodes only allows institutions or organizations within the system to read and send transactions. [0003] At present, the alliance chain has the following problems: 1) During the continuous development of the alliance chain, many underlying technology platforms with different forms have emerged, but the communication protocols of the alliance chains based on different underlying technology platforms are different from each other, resulting in the differences between these alliance chains.

Problems solved by technology

[0003] At present, the alliance chain has the following problems: 1) During the continuous development of the alliance chain, many underlying technology platforms with different forms have emerged, but the communication protocols of the alliance chains based on different underlying technology platforms are different from each other, resulting in the differences between these alliance chains. It is difficult to communicate with each other, to recognize each other, to trust each other, to visit each other

2) While the application of the alliance chain continues to deepen and expand, it will also bring a series of risks and challenges. However, the current supervision of the alliance chain still lacks regulatory technical solutions, and there are many technical problems to be solved, which is not conducive to the healthy development of the alliance chain
