[0003]
However, the current blockchain cross-chain technology needs to include notary mechanisms, side chains / relays, hash locks, distributed private key control, etc., and the code is complex to implement, and it is prone to errors during data transmission. The problem of message congestion and message loss leads to low reliability of the data interaction process between chains

Embodiment Construction
[0060] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0061] The blockchain-based inter-chain interaction method provided by this application can be applied to such as figure 1 The inter-chain interaction system 100 of the blockchain is shown. The blockchain inter-chain interaction system 100 includes a blockchain platform 110 (not shown in the figure), a first blockchain 120 and a second blockchain 130 . Among them, the block chain platform 110 is used to select a notary node from each verification node list of the first block chain 120 and the second block chain 130 according to a preset random selection mechanism, and the...

The invention relates to an inter-chain interaction method, system and device based on a block chain and computer equipment. The method comprises the following steps: receiving a first cross-chain interaction message generated by a first block chain according to a created cross-chain interaction contract, and storing the first cross-chain interaction message into a first cache queue; verifying thecross-chain interaction contract corresponding to the first cross-chain interaction message in the first cache queue, and taking the cross-chain interaction message of the cross-chain interaction contract passing the verification as a second cross-chain interaction message; and storing the second cross-chain interaction message into a second cache queue, reading the second cross-chain interactionmessages from the second cache queue in sequence, and sending the read second cross-chain interaction messages to the second block chain, wherein the second cross-chain interaction messages are usedfor indicating the second block chain to process cross-chain interaction contracts corresponding to the second cross-chain interaction messages, and a cross-chain data interaction processing result isobtained. By adopting the method, the message congestion in the cross-chain interaction process is reduced, and the interaction reliability between the block chain chains is improved.
Description
technical field [0001] The present application relates to the technical field of block chains, in particular to a block chain-based inter-chain interaction method, system, device and computer equipment. Background technique [0002] With the development of blockchain technology, blockchain cross-chain data interaction technology has emerged. Whether it is for public chains, alliance chains or private chains, blockchain cross-chain data interaction technology is to transform the blockchain from scattered islands The good medicine rescued from the epidemic is the bridge for blockchain connection and outward expansion. [0003] However, the current blockchain cross-chain technology needs to include notary mechanisms, side chains / relays, hash locks, distributed private key control, etc. The problem of message congestion and message loss leads to low reliability of the data interaction process between chains. Contents of the invention [0004] Based on this, it is necessary t...
