Embodiment 1

[0018] A blockchain heterogeneous chain cross-chain transaction method, an anchor node 100 and a cross-chain route 200 are established between the first blockchain and the second blockchain, such as figure 1 As shown, the anchor node 100 is connected to the first blockchain, the cross-chain router 200 is connected to the second blockchain, and the anchor node 100 and the cross-chain router 200 communicate with each other. Such as figure 2 As shown, the method includes the following steps:

[0019] A) User node S of the first blockchain 1 The digital asset D of the blockchain where it is located 1 Transfer to the cross-chain transaction contract to generate cross-chain transaction information, and the miner nodes of the first block chain will package the cross-chain transaction information on the chain.

[0020] B) The anchor node group listens to the new block of the first blockchain, identifies the cross-chain transaction information contained in the new block, extracts t...

Embodiment 2

[0029] In this embodiment, on the basis of the first embodiment, a supervision node is established. The supervisory node is used to clean up the anchor node 100 and the cross-chain router 200 with bad behavior, to ensure the credibility of the anchor node 100 and the cross-chain router 200, and to realize the opening of the anchor node 100 and the cross-chain router 200 Free to join, thus solving the problem of low service efficiency of cross-chain transactions. The supervisory node itself is also an open node. The supervisory node runs a supervisory smart contract. After the node installs and runs the supervisory smart contract, other supervisory nodes will verify it. If more than the preset number of supervisory nodes pass the verification, the supervisory smart contract will be run The node is used as a new supervisory node. The verification of the newly added nodes by the rest of the regulatory nodes includes verifying the version of the regulatory smart contract.

Abstract

The invention relates to the technical field of blockchain cross-chain, in particular to a blockchain heterogeneous chain cross-chain transaction method, which comprises the following steps that: A) auser node S1 of a first blockchain transfers digital assets D1 to a cross-chain transaction contract, generates cross-chain transaction information and uploads the cross-chain transaction informationto a chain; b) the anchoring node group monitors cross-chain transaction information, generates transaction intermediate information and performs multiple signatures; c) transaction intermediate information is monitored by a cross-link router, the transaction intermediate information is converted into cross-link transaction information of a second block chain structure, and then the cross-link transaction information is opened; d) the user node of the second block chain selects the digital assets to receive, transfers the digital assets D2 to the user node S1, and generates cross-chain transaction receiving information; e) the anchoring node group generates transaction confirmation information; and F) the cross-link router monitors transaction confirmation information, and the digital asset D1 is sent to the user node S2. The beneficial effects of the invention are that the method avoids the centralization of the cross-chain transaction through the open anchoring node group and the cross-chain routing, and improves the safety and reliability of the cross-chain transaction.

Description

technical field [0001] The invention relates to the technical field of block chain cross-chain, in particular to a block chain heterogeneous chain cross-chain transaction method. Background technique [0002] Blockchain is an emerging information technology based on encryption technology and distributed ledger technology, and its essence is a shared database. The data or information stored in it has the characteristics of "unforgeable", "retaining traces throughout the process", "traceable", "open and transparent", and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation and created a reliable "cooperation" mechanism. Due to the above properties of the blockchain, it has broad and rich application prospects, and has developed rapidly in recent years. [0003] However, the blockchain technology only stipulates the technical content at the principle level, and does not make any restrictions on the specific implem...
