Problems solved by technology

[0009] Therefore, the current cross-chain solutions at home and abroad are still in the exploratory stage. Most of the cross-chain interconnection solutions are mainly based on cross-chain asset replacement and decentralized storage, which cannot be supervised, and there are problems such as high hardware requirements and lack of practicability. , not yet very user-friendly

Abstract

The invention provides a cross-chain asset replacement scene-oriented oracle machine-based block chain interconnection method and device, and the method comprises the steps that an oracle machine main node monitors a cross-chain request event triggered by a source block chain, signs a cross-chain request threshold value to obtain a preparation request, and sends the preparation request to an oracle machine supervision / common node; each oracle supervision / common node performs threshold signature on the preparation request to obtain a to-be-aggregated request message, and sends the to-be-aggregated request message to other oracle supervision / common nodes; each oracle machine supervision / common node verifies the cross-chain request content, and when the total number of threshold signatures reaches a set number, the threshold signatures are aggregated; the oracle machine common node generates an aggregated message, and the oracle machine supervision node verifies the compliance of the cross-chain request content and generates the aggregated message; and the first node obtaining the aggregated signature sends an aggregated message to the target block chain, verifies a node consensus and executes a cross-chain transaction according to a result. Through the scheme, controllable and credible cross-chain transaction can be realized.

Description

technical field [0001] The present invention relates to the technical field of blockchain, and in particular, to an oracle-based blockchain interconnection method, device and storage medium for cross-chain asset replacement scenarios. Background technique [0002] According to statistics from CoinMarketCap, as of July 24, 2020, there were 5,784 cryptocurrencies based on blockchain technology in the world, with a total market value of more than $285 billion. In addition, with the development of blockchain technology, blockchain not only refers to a public chain based on cryptocurrencies and all nodes can join and exit, but also a consortium chain and private chain that allow some authorized nodes to join and exit . The prosperity and development of various blockchains has made the application scenarios of blockchain no longer limited to cryptocurrencies, but also extended to finance, energy, logistics and other fields. [0003] However, the prosperity and development of blo...
