In digital higher education, digital transformation is mandatory. Blockchain technology, with its unique features of distributed ledgers, consensus mechanisms, smart contracts, and traceability, provides a new perspective for digital educational resource platforms. In this study, a blockchain-based design was proposed for an open service platform for digital education resources in universities. The platform addresses challenges such as limited openness, complex resource copyright certification, and difficulty in effectively ensuring resource security and quality. The platform offers resource publishing, resource trading, operation management, and interface management ensuring data security using the distributed ledger of blockchain. Consensus mechanisms and smart contracts are used to ensure fairness and efficiency in platform operation and automate resource transactions. Traceability is utilized to ensure the certification and protection of resource copyrights.
