Problems solved by technology

It does not rely on third-party participation, but implements a Super LightClient using a special MMR data structure on the chain. Although it solves the cost and performance problems of ordinary Light Clients and realizes cross-chain verification, due to the light The node itself is a one-way verification, and cannot achieve two-way cross-chain in the mainstream blockchain cross-chain

Embodiment 1

[0076] The present invention proposes a construction method of a cross-chain transfer bridge, which introduces light node verification, relay engine retrieval, management mechanism operation and maintenance, and cross-chain mirroring. The overall flow chart is as follows figure 1 As shown, its specific implementation scheme is as follows:

[0077] Set up light nodes in the first blockchain, where the first blockchain is a plurality of business blockchains to which the cross-chain requester belongs, such as figure 2 Shown is a schematic diagram of the interaction between the first block chain and the transfer bridge. The light node monitors and records the cross-chain transactions in the first block chain in real time, verifies the cross-chain transactions, and sends the verified cross-chain transactions to the central following the engine;

[0078] The relay engine receives the cross-chain transaction verification after the first block chain light node verification and retri...

Embodiment 2

[0106] Combined with the construction method of the cross-chain transfer bridge, the present invention also introduces a construction system of the cross-chain transfer bridge, which adopts a modular design and includes a verification module, a management module and a cross-chain transfer module;

[0107] The verification module is used for the light node to verify the cross-chain transaction information, and after the verification is confirmed, it is sent to the relay engine to further retrieve the transfer chain, and the cross-chain transaction information is sent to the corresponding transfer chain;

[0108] The management module is used to associate the transfer chain and the vault, lock the first blockchain asset in the vault according to the cross-chain transaction information, and set the management mechanism to use the unique identifier and key derivation scheme to pair the vault and transfer chain for operation and maintenance management;

[0109] The cross-chain tran...

Abstract

The invention discloses a construction method and system of a cross-chain transfer bridge; a modular design is adopted, the system comprises a relay engine, a transfer chain and an insurance vault, and the specific construction method comprises the following steps: setting a light node in a first block chain to verify and confirm a cross-chain transaction, sending the confirmed cross-chain transaction to the relay engine, retrieving a switching chain corresponding to the cross-chain transaction, and sending the cross-chain transaction to the corresponding switching chain for storage; associating the transfer chain with the insurance library, locking the first block chain assets in the insurance library according to the cross-chain transaction information, and setting a management mechanism to perform operation and maintenance management on the insurance library and the transfer chain; according to the cross-chain transaction information, carrying out transfer transaction between the second block chain and the transfer chain through mirror image cross-chain. According to the invention, cross-chain transactions are confirmed through light node verification, the relay engine quickly retrieves association, decentralized asset fixation is realized by using the insurance library, a management mechanism is set for safe operation and maintenance, and finally bidirectional cross-chain intercommunication among multiple chains is achieved.

Description

technical field [0001] The invention belongs to the technical field of blockchain and cross-chain, and in particular relates to a construction method and system for a cross-chain transfer bridge. Background technique [0002] After the development of the blockchain in recent years, no matter the public chain consortium chain has basically realized the process from development to implementation, and each blockchain has gathered a certain number of users, forming a certain scale of the ecosystem. At present, each blockchain can expand its capacity through sidechain technology. However, the users, underlying technologies and characteristics of each blockchain are not exactly the same. If you want to increase the blockchain capacity and application scale Large enough and fast enough development, the development of a single blockchain cannot achieve this goal, and the method of parallel and Unicom must be adopted for development, that is, each blockchain develops its own ecology,...
