Description

Technical Field

[0002] Traditional financial systems rely on centralized ledgers and manual clearing processes, which have defects such as high risk of data tampering, delayed clearing time, and high cross-institutional collaboration costs. Existing technologies in cross-border payment and supply chain finance scenarios rely on intermediary systems such as SWIFT, resulting in long settlement cycles and information opacity, and are unable to meet the real-time requirements of high-frequency trading scenarios. Summary of the Invention

[0003] The purpose of the present invention is to provide a blockchain-enabled distributed ledger system to address the above-mentioned problems in the prior art, thereby solving all or one of the above-mentioned problems in the prior art.

[0004] In order to solve the above technical problems, the specific technical solutions of the present invention are as follows: The present invention provides a blockchain-enabled distributed ledger system, comprising: A blockchain network node cluster, a smart contract engine, and a distributed storage module are configured to implement tamper-proof records of transaction flows through a consensus algorithm, support automatic triggering of settlement instructions by smart contracts in inter-bank clearing scenarios, and eliminate manual intervention.

[0005] As an improved solution, the blockchain network node cluster is specifically used to adopt a dynamic Byzantine fault tolerance mechanism, support the flexible joining and exit of alliance chain nodes, and improve transaction confirmation efficiency through a hybrid consensus algorithm of proof of stake and practical Byzantine fault tolerance.

[0006] As an improved solution, a multi-level verification mechanism is deployed in the smart contract engine, including a formal verification module and a runtime status monitoring module to ensure the atomicity and compliance of inter-bank clearing contracts.

[0007] As an improved solution, the distributed storage module integrates off-chain data storage and on-chain hash evidence architecture, which is used to realize encrypted storage and fast retrieval of transaction credentials through the IPFS distributed file system.

[0008] As an improved solution, the blockchain-enabled distributed ledger system is also equipped with a cross-chain atomic swap protocol, which is used to realize asset transfer and certificate synchronization between different blockchain networks through hash time-locked contracts, supporting real-time settlement in cross-border payment scenarios.

[0009] As an improved solution, the blockchain-enabled distributed ledger system also deploys a privacy protection enhancement module, which uses zero-knowledge proof and ring signature technology to hide sensitive account information and transaction amounts while ensuring that transactions are auditable.

[0010] As an improved solution, the blockchain-enabled distributed ledger system also deploys a smart contract hot update mechanism, which is used to achieve secure upgrades of contract logic through dual channels of administrator keys and community governance, and adapt to changes in financial regulatory policies.

[0011] As an improved solution, the blockchain-enabled distributed ledger system is also deployed with a dynamic sharding management engine, which is used to automatically divide blockchain shards according to transaction load, thereby achieving parallel clearing and storage expansion in high-concurrency scenarios.

[0012] As an improved solution, the blockchain-enabled distributed ledger system also deploys an abnormal transaction detection engine, which is used to analyze transaction patterns through machine learning models and automatically trigger the circuit breaker protection and manual review mechanism of the smart contract.

[0013] As an improved solution, the blockchain-enabled distributed ledger system is also deployed with a cross-chain oracle module to verify the authenticity of external business data through decentralized data sources and ensure the credibility of on-chain evidence of supply chain financial certificates.

[0014] The beneficial effects of the technical solution of the present invention are: by constructing a distributed ledger architecture driven by blockchain and smart contracts, the present invention innovatively integrates dynamic consensus algorithms, cross-chain atomic swaps, and privacy computing technologies to break through the performance bottlenecks and trust barriers of traditional centralized clearing systems.
