D-SELI: Proposal for a Distributed Educational Blockchain Network with IPFS

Abstract

In recent years, there has been an increase in the use of blockchain networks in the educational field, with projects such as SELI (Smart Ecosystem for Learning and Inclusion) that have developed blockchain networks to exchange academic certificates and resources. However, storage space is limited in the use of blockchain networks since all transactions are stored in each node, which can lead to space and accessibility problems in centralized blockchain networks. To address this problem, this article proposes modifying the SELI educational blockchain network through the Interdisciplinary File System (IPFS) protocol in a fully distributed blockchain network, D-SELI. The D-SELI proposal seeks to solve the limitation of storage space and accessibility in blockchain networks by incorporating the IPFS protocol. IPFS is a distributed file system that uses a peer-to-peer network to store and share content decentralized, overcoming storage problems on a blockchain network. Implementing IPFS in D-SELI allows educational resources and certificates to be stored in a decentralized manner, eliminating the need to keep all transactions on each node in the network, which reduces the storage load on the nodes and improves accessibility to the data. Furthermore, being a wholly distributed network, data location problems present in centralized blockchain networks are overcome. In summary, this article presents a proposal to modify the SELI educational blockchain network through the use of the IPFS protocol in a fully distributed network (D-SELI) to solve the limitation of storage space and accessibility in blockchain networks, improve the efficiency and scalability of the network in the educational field.
