[0055] figure 1 It is the architecture diagram of the interconnection chain. Interchain is a blockchain used for transaction forwarding between different blockchains. Any blockchain can be connected to the Internet chain 101, and complete cross-chain transactions with the help of the Internet chain 101. The blockchain connected to the interconnected chain 101 is called a parallel chain. figure 1 In the parachain network 102, each node (parachain network node and data sending and receiving node) maintains a complete copy of the parachain 102. Similarly, each node in the parachain network 103 maintains a copy of the parachain 103. A complete copy, each node in the parachain network 104 maintains a complete copy of the parachain 104.

[0056] Each parachain network contains one or more data sending and receiving nodes. Each data sending and receiving node keeps a complete copy of its own parachain. At the same time, each data sending and receiving node holds the account of t...

[0103] The inventive idea and main implementation steps of this embodiment are similar to those of the first embodiment, and the similarities will not be repeated here. The difference from Embodiment 1 is that processors and memories are used in this embodiment, and the specific method steps are implemented by parallel chains and / or interconnection chains distributed on the above-mentioned processors and / or memories.

[0104] It is worth clarifying that the sending module, verification module, and redemption module in the parachain described in the embodiment of the present invention can be implemented by hardware such as computers, routers, and gateways, or by pure software, or by software It can be implemented in a hard-bonded manner, as long as the functions that each node should have in the following embodiments can be realized.

Abstract

The invention discloses a chain-crossing account transfer system and method between different block chains. The method includes the steps of receiving a first transaction request, wherein in the firsttransaction request, a first token in a first parallel chain is requested to be transferred to a second parallel chain; searching an order list for one or more orders matched with the first transaction request, according to the one or more orders, generating an order combination, and freezing the orders in the order combination; generating a second transaction request including the order combination, releasing the second transaction request to the first parallel chain through an interconnection chain; receiving a third transaction request, wherein the third transaction request is generated according to an execution result of the second transaction request in the first parallel chain; when the third transaction request passes verification, determining that the first transaction request andthe orders in the order combination are completed, and keeping all transaction records. The chain-crossing account transfer system and method have good extensibility and can guarantee the atomicity in the process of account transfer.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a cross-chain transfer system and method between different block chains. Background technique [0002] With the rapid development of blockchain technology and applications, various independent blockchains have emerged, and the realization of cross-blockchain transactions has become an urgent need for today's blockchain applications. For example, the most common demand at present is cross-blockchain currency transactions, that is, the transfer of virtual currency from one blockchain to another, so as to realize the value circulation between various blockchains. [0003] In response to the needs of cross-chain transfers, industry and academia have proposed some preliminary solutions. [0004] BTCRelay and BTC-Market realize one-to-one cross-chain transfer. In this scheme, the smart contract deployed on Ethereum can receive Bitcoin's block header and SPV (Simplified Payment V...
