Abstract: With the development of the digital economy, digital trust technology has been widely applied in various fields of socio-economic activities. Blockchain technology, as a paradigm of digital trust technology, has been widely accepted and effectively utilized by a vast number of small and medium-sized enterprises (SMEs) in the supply chain due to its digital features such as distributed ledger, decentralization, and consensus sharing. Through digital supply chain management, core enterprises can conduct penetrative management and provide financing convenience to upstream and downstream enterprises under the condition of active confirmation of rights, influencing digital supply chain finance in terms of “re-intermediation trust”, “trustless credit”, and “from ‘interlocking’ to ‘parallel’”, strengthening financial institutions' tracking of enterprise transaction information and review of financing qualifications, and effectively reducing financing risks.

Key words: digital economy, blockchain, digital trust, supply chain finance
