Open learning is now facing a complex higher education ecosystem that involves a variety of heterogeneous information systems and comprises decentralized stakeholders, such as universities, professors, students, and software vendors. Authentic, non-repudiable, and fast available data sharing among open learning information systems and stakeholders is a key issue that remains unresolved. To solve this problem, this paper proposes a consortium blockchain extended architecture featuring integration and cross-chain functions to provide a unified and trusted data-sharing infrastructure for open learning. The overall architecture consists of three elements: a blockchain-integrated open learning scenario schema; a blockchain-integrated open learning application model; and a pragmatic blockchain integration framework. The proposed blockchain integration framework is implemented based on Hyperledger Fabric 1.4. A trusted open-learning behavior and achievement management application is developed as a proof-of-concept which integrates two educational institutions’ four productional learning systems into a blockchain network and has stably run over six months. A suite of experiments is designed and executed to verify our blockchain system’s viability and scalability. The test result shows the implementation of the blockchain system is competent for the production environment and outperforms related works investigated. However, it does have limitations and optimization potential, which will be studied in the future.

“…This makes it easier for university administrators or developers to install, troubleshoot, and maintain such systems. But by virtue of their centralized nature, these systems are often vulnerable to cyber-attacks, malware, and hardware or system failure (Mishra et al, 2021;Alnafrah & Mouselli, 2021). In any of these unfortunate events, the data records stored on these systems could be damaged, and also irrecoverably lost.…”

Blockchain technology will soon have progressed from being an innovation to the norm of application development and the digital revolution. The technology of a blockchain is essential based on a widely distributed, peer-to-peer ledger of transactions and balances. This ledger is essentially a huge database broken down into chunks known as blocks. These blocks and the entire ledger are stored in millions of copies on that particular blockchain network on extremely powerful computers known as nodes. There is a majority-based consensus that exists for every transaction that is carried out and put in a block. To tamper with this ledger would require computing power either equal to or greater than 51% of all the nodes active for that particular blockchain. Even if this power were acquired to tamper with or hack the particular blockchain, the cryptocurrencies or tokens that are transacted on the blockchain would essentially be overturned and considered worthless due to the other nodes detecting a hack or attempt to steal tokens or wallet balances. This is how the first cryptocurrency like bitcoin, along with many other cryptocurrencies on their respective blockchain technologies, operate.

“…Therefore, offchain storage models have been proposed to store the incoming transaction data, and only the hash of the corresponding data, which are of significantly smaller size compared to the original data, can be stored in the blockchain. Smart contracts and distributed hash tables (DHT) can be used to establish a link between the hash in the chain and the physical storage [5]. A distributed file system among the already available nodes is used to maintain the offchain storage [1].…”

Blockchain is an innovative technology which enabled new applications for solving numerous problems in distributed environments such as the internet of things (IoT) equipped food supply chains (FSCs). In FSCs, the large volume of IoT data such as audio, video, images, and sensor data will be transferred to ensure the traceability of the food to its source. When blockchain technology is used in an FSC, the storage requirements in the nodes will grow with time, since blockchain only allows information adding, without deleting the already stored information. Therefore, it is evident that offchain storage offers more flexibility than onchain storage in IoT equipped supply chains. This paper proposes a scalable storage scheme using offchain storage, where the data from IoT devices in the supply chain will store offchain. To reduce the growth of offchain storage, we exploit the fact that some information regarding a particular food item may not be required after the expiration date. The scalability of the proposed scheme is validated through numerical and experimental results.
