Introduction
Supply Chain Finance (SCF) plays a crucial role in enhancing supply chain competitiveness by optimizing capital flow. The advent of Blockchain technology, with its features of data integrity, authenticity, privacy, and information sharing, has the potential to revolutionize SCF. This survey aims to provide a comprehensive overview of Blockchain-based SCF, summarizing current applications and proposing future research directions.
Supply Chain Finance
Supply Chain Finance Overview
Global trade globalization has complicated supply chain mechanisms, putting pressure on capital flow. Large enterprises often dominate supply chains, causing financing difficulties for Small and Medium Enterprises (SMEs). SCF aims to alleviate these issues by optimizing capital flow management and reducing financing risks and costs.
What is Supply Chain Finance?
SCF integrates financial flows into the physical supply chain to improve management. It provides comprehensive financial products and services to upstream and downstream enterprises based on core customers. SCF includes supplier financing and distributor financing, with specific programs like accounts receivable financing, inventory financing, prepayment financing, and strategic relationship financing.
Research Direction of Supply Chain Finance
Research on SCF can be divided into management science and computer science perspectives. Management science focuses on financial and supply chain attributes, while computer science leverages advanced technologies like big data, cloud computing, artificial intelligence, and Blockchain to optimize SCF operations.
Blockchain Technology
Blockchain Overview
Blockchain technology, first introduced with Bitcoin by Satoshi Nakamoto in 2008, has gained significant attention in various fields, including finance, supply chain, and healthcare. Blockchain’s decentralized, tamper-proof, and cryptographic features make it suitable for SCF applications.
What is Blockchain?
Blockchain is a data structure that stores historical transaction data in a decentralized, transparent, and secure manner. It consists of blocks linked in chronological order, forming a chain. Each block contains a block header and block body, with the header including metadata and the body containing transaction records.
Blockchain Structure and Core Technology
Blockchain combines several technologies, including distributed storage, encryption, peer-to-peer networking, incentive mechanisms, and smart contracts. These technologies ensure data integrity, security, and consensus among network participants.
Research Directions of Blockchain Essential Technology
Storage
Blockchain’s distributed storage ensures data transparency but poses storage challenges. Research focuses on reducing storage consumption and expanding off-chain storage space.
Peer-to-peer
Peer-to-peer networks support Blockchain’s decentralization. Research aims to improve message propagation latency and enhance security and trust.
Encryption
Encryption ensures data security and privacy in Blockchain. Research includes homomorphic encryption, zero-knowledge proofs, and attribute-based encryption.
Consensus Mechanism
Consensus mechanisms ensure data consistency in Blockchain networks. Research includes permissioned and permissionless consensus mechanisms, such as Proof-of-Work (PoW) and Proof-of-Stake (PoS).
Incentive Mechanism
Incentive mechanisms motivate nodes to participate in Blockchain networks. Research includes computation, storage, and transmission incentives.
Smart Contract
Smart contracts automate transactions based on predefined conditions. Research focuses on enhancing security, privacy, computation efficiency, and overall performance.
Cross Chain
Cross-chain technology enables interoperability between different Blockchains, addressing information silos and enhancing data sharing.
Applications on the Combination of Blockchain with Other Computer Technologies
