Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings.

[0041] like figure 1 Shown, specific embodiment of the present invention and implementation mode are as follows:

[0042] 1) User node S 1 There is a digital asset D in the first blockchain 1 , it is necessary to obtain blockchain B through cross-chain transactions 2 digital assets D 2 ;

[0043] user node S 1 Generate digital assets D 1 Go to cross-chain smart contract C 1 Address transfer information M 1 , and use your own private key to transfer information M 1 Signature Generation Signature δ 1 , after the signature is generated, the cross-chain transfer transaction information {M 1 ,δ 1}issue;

[0044]

[0045] The miner nodes in the first blockchain network receive transfer information M 1 and signature δ 1 After the verification is passed, the cross-chain transfer transaction information {M 1 ,δ 1}Pack up the chain.

[0046] 2) The anchor no...

Abstract

The invention discloses a method for efficiently carrying out cross-chain information transaction interaction in a block chain. The first blockchain node needing cross-chain transaction sends a firstdigital asset to the first cross-chain smart contract; if the anchoring node group monitors that the cross-chain information is linked, multiple signatures are carried out and published; the other blockchain nodes select the first digital assets to receive according to the public information, transfer the second digital assets into a second cross-chain smart contract, and obtain the second digitalassets by the first blockchain node after the uplink confirmation; after the anchoring node group monitors uplink confirmation of the received information, information transferred to the receiving node by the first digital asset is generated and signed; and the first cross-chain transaction contract transfers the first digital asset to the receiving node after obtaining the signature of the anchoring node, and the receiving node obtains the first digital asset after confirmation. According to the invention, the cross-chain transaction is realized through the anchoring node and a multi-signature mode, and two transaction parties can efficiently complete the cross-chain information interaction only through one-time initiating and receiving operation.

Description

technical field [0001] The invention relates to a cross-chain information processing method of block chain technology, in particular to a method for efficiently performing cross-chain information transaction interaction in the block chain. Background technique [0002] The blockchain is the underlying technical architecture including cryptographic algorithms, P2P, distributed, etc. All users participating in the blockchain network jointly maintain ledgers and realize distributed bookkeeping and auditing to ensure the authenticity and integrity of information. It cannot be tampered with, which makes the blockchain have the characteristics of decentralization, trustlessness, safety and reliability. With the development and application of blockchain technology, many types of blockchain projects have emerged. Since various blockchains use different underlying technologies, chains cannot communicate with each other, and a centralized third party must be used for information tran...
