Issues in the current education system and different educational organizations can be resolved using blockchain technology in the core area. Furthermore, it can be determined using blockchain technology in the education system.
Blockchain can transform the traditional record storage of students and the staff over the distributed network. As the data is stored on the distributed system, it is secure and more transparent. In addition, the overall data accuracy and immutability is preserved in the distributed blockchain environment.
Generally, Blockchain consists of the various steps while deploying the data onto the blockchain network. Therefore, start trading to get into blockchain. Usually, the verifying authorities and the central institutions take more time to carry out the operations, which is time-consuming. Using blockchain technology, we can eliminate the risk of significant server downtime. As we are not relying on the central authority, the process takes a fewer amount of time. In addition, the data stored on the Blockchain is tamper-proof and cannot be modified once deployed on the blockchain network.
Blockchain In Education
In education systems, the certificates state that the achievements of the learners or educators and different activities are mostly issued on paper or other physical formats. However, paper certificates are prone to tampering and forging. On the other hand, the digital certificates stored on the blockchain networks are difficult to forge, and they are tamper-proof.
Blockchain technology supports protection against counterfeit certificates and simplified verification of Certificates with a lesser amount of resources. Blockchain consists of three steps while considering the digital certification and storing the data onto the Blockchain.
Educators only receive copies or notarized work of learner’s paper certificates. To verify these certificates, the educators need to rely on the central authority. It is a time-consuming process so that blockchain technology can be effectively used in the education system.
Currently, the Sony and University of Nicosia have successfully implemented the Blockchain in education to store digital certificates and issue degrees.
Digital Certification
Initially, the learner inputs his personal information with the unique id, and then the data is kept on to the learner’s Blockchain. Later the data sent for verification to the respective verifying institution. Finally, after successful confirmation of the data, the success token is sent to the learner, and then the data is safely stored onto the institute’s private blockchain network.
Essential Characteristics of Digital Certificates
The certificates are stored digitally onto the blockchain network with the generated hash. Here the issuer and the verifying authority has their separate Blockchain for storing the digital certificates. Over the regular certificates, they are stored digitally on thousands of computers, which will make them more secure and robust than the standard certificates. In addition, it requires fewer resources to maintain, issue and access than the existing digital certification.
Digital Signature
The digital signature consists of the time stamp, which is indeed generated by the specific user and cannot be modified or tampered with. Here the user uses the private key to sign the document digitally and to use his public key. The recipient can verify the identity and confirm the record. The digital signature is more secured than the electronic signature and can be used to keep data more securely.
Benefits over Traditional Approach
Without the central authority, we can apply the Blockchain in the education system, which can be used in the formal assessment and storing the digital certificate and the degrees. Informal learning data such as the research experience, skills and the online learning experiences and individual interests can be easily stored onto the Blockchain is a safer format. Private information of learners and educators can be held onto the blockchain networks in immutable form.
Distributed Database in Educational
The Environment Blockchain ledger is distributed so the remaining candidates can monitor any changes made to reduce problems like degree fraud. As the overall data is stored on the distributed blockchain network, all the learners can keep track of the details, so the widespread tampering of the actual data can be avoided, as the blocks on the Blockchain cannot be altered once they are deployed. Using the proof of work algorithm, the data stored on the distributed blockchain network can be verified, and then it’ll be held on the web with valid credentials.
System Working Overview
The learner consists of their ID, which will help them to identify them on the blockchain network. They are provided with different rights while storing the data on to Blockchain. For example, learners can inert the theory attendance, insert assignment marks, insert lab and test attendances. After confirming the learner’s identity through the verifying institution, he can successfully store the data onto the Blockchain using the smart contracts.
Future Educational Applications
- “Learning is earning” can be applied by considering the digital currencies in the learner’s wallet, and it can motivate learners to join different educational activities.
- Formative assessment is challenging as we need to record all the details of the learner’s activities. It can be made more simplified and can be used more systematically in the educational system.
- We can maintain the digital identity of the difference between these parties safe, and it can be securely stored on the blockchain network.
- The smart contract will reduce the overall need for the third party’s involvement and increase the overall performance.
- The more the educational issues can be solved using intelligent contract-based blockchain systems.
- Every detail of teaching and learning can be made more simplified using blockchain techniques.
Conclusion
Blockchain works on distributed technology. Smart contracts can be designed and deployed to the Ethereum blockchain that can be created using the solidity programming language. Blockchain can be applied to private, public and consortium sectors depending upon the usage and the scope of the Blockchain. The education system can benefit from this scalability of the Blockchain and can be effectively helpful in educational institutions.
