Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] see Figure 1-7 , the present invention provides a technical solution: a cross-chain asset transfer method based on smart contracts, including the following specific steps:

[0045] S1: Design the SLife structure of "main chain + sub-chain", respectively adopt Dpos+PBFT consensus algorithm, adopt double contract and independent visa mechanism to realize interconnection and intercommunication; the main chain guarantees the fund security of the sub-chain,...

Abstract

The invention discloses a cross-chain asset transfer method implemented based on a smart contract, which comprises the steps of designing an SLife structure of a main chain plus a sub-chain, designing a variant algorithm of Fts to select a sub-chain consensus node from super nodes of the SLife main chain, submitting a sub-chain verification node public key address and a domain name to a main chain contract by referring to a G.O.D algorithm, wherein the information processing module is used for a user to obtain information required by a consistent sub-chain gensis file from a contract interface, and designing an independent process visa mechanism by referring to a DKG algorithm to poll, sign and issue the on-chain state of a sub-chain contract; according to the invention, exchange functions of points and other values of different platforms are realized, real and credible point exchange of different platforms can be realized, and distributed service tracing is realized without tampering; according to the method, share exchange and transfer between different chains can be achieved under the condition of small resource deployment and consumption by means of the combination of the smart contract and the protocol, and good flexibility and expansibility can be achieved.

Description

technical field [0001] The invention relates to the field of cross-chain technology, in particular to a cross-chain asset transfer method based on smart contracts. Background technique [0002] Blockchain cross-chain refers to the direct circulation of value across the barriers between chains and chains through technical means. Simply to transfer information from one chain to another. The easiest thing to understand is to exchange ETH for BTC, which is simply an asset exchange. [0003] Value circulation is that blockchain is a kind of distributed ledger. A blockchain is an independent ledger, and two different chains are two different independent ledgers, and the two ledgers are not related. In essence, there is no way to transfer value between ledgers, but for a specific user, the value stored by the user on one blockchain can become the value on another chain, which is the circulation of value. [0004] Token: In Chinese, the pass is a negotiable certificate, a repres...
