A Method for Sharing of University Digital Resources Based on Alliance Chain

The sharing of digital educational resources in colleges and universities still faces challenges such as high cost, security problems, and inconsistent standards. The decentralized, immutable and traceable characteristics of blockchain technology are of great significance to solving these problems and educational resource sharing can be realized through its distributed ledger and security mechanism. Aiming at the above problems, in this paper, a method of university digital resource sharing is proposed based on alliance chain with identity authentication, resource sharing, privacy protection and value exchange as the main characteristics. Through the alliance chain technology, using its permanent record and immutable characteristics to achieve efficient digital resource management; Combine the semi-centralized consensus architecture of alliance chain and hierarchical node design to realize efficient resource sharing circulation and management; Based on smart contract and digital signature technology, data access and sharing can be de-trusted and intelligent. Experimental results show that the resource sharing model based on alliance chain technology can achieve good results in the sharing of academic digital resources within and among universities.
