Joint cloud computing environment value exchange-oriented cross-chain communication method

Abstract

The invention discloses a joint cloud computing environment value exchange-oriented cross-chain communication method, and aims to ensure the security, reliability and high efficiency of a value exchange process. According to the technical scheme, a cross-chain communication system consisting of a cross-chain communication module, a node management module, a verification module and an accounting module is installed in each user node on each block chain; a midchain is established; a route node is selected from the midchain; value transfer and communication between chains are finished by the route node; the cross-chain communication module of a sender constructs a fund pool for the sender, a receiver and the route node, and performs fund transfer according to a fund transfer scheme; the verification module of the receiver verifies the effectiveness and availability of funds of the sender by adopting a smart contract; the accounting module of the receiver broadcasts a transaction result; and the sender, the receiver and the MidChain generate new blocks for storing transaction data. By adopting the method, the security, reliability and high efficiency of the value exchange process can be ensured; and seamless cross-chain communication between the chains is realized.

Description

technical field [0001] The present invention relates to the field of blockchain and distributed cloud computing, in particular to a communication method for cross-chain value exchange using blockchain as a basic technical support. Background technique [0002] The concept of blockchain was proposed as the underlying technology of Bitcoin in Satoshi Nakamoto's "Bitcoin: A Peer-to-Peer Electronic Cash System" (ie "Bitcoin: A Peer-to-Peer Electronic Cash System") in 2008 . In order to realize a point-to-point decentralized trusted accounting system, Satoshi Nakamoto put each transaction information of Bitcoin into a block (that is, a block structure for storing transaction data hash value and timestamp) In , each block is connected into a chain according to the order of timestamp, which is called a blockchain. A user node on a certain blockchain (also referred to as a user node belonging to a certain blockchain) refers to a user terminal that synchronizes all blocks on the bl...

AI Technical Summary

Problems solved by technology

Therefore, a complete mechanism is needed to maintain the traceability and stable operation of the transaction. At present, the technology often supervises and maintains the transaction through a third party (such as Escrow in Interledger). Fraud), so the security of the entire value exchange process cannot be guaranteed

[0012] 2. Efficiency issues

Most of the current technologies spend a lot of time to verify the validity of funds (for example, in a value transfer, side chains spend 2-4 days to lock funds), which greatly reduces the efficiency of value exchange
