DISCIPLINA functionality. Part 2
Since the DISCIPLINA blockchain will disclose the private student data in order to provide them to recruiters or researchers, it is essential to ensure the integrity of such a deal.
To do so, the project team has developed the Data Disclosure algorithm that guarantees the transmission of the valid data in return for the cryptocurrency transaction. What is special about this algorithm is that when an educational institution sends the data that has not been verified in the public blockchain (for example, if a student’s grade was falsified) to the customer, it is fined a fixed amount. However, the customer doesn’t lose their money and only the depersonalized part of the data will be disclosed.
To check the validity of transactions in public chain, we are planning to create a network of so-called “Witnesses” that will employ the consensus algorithm based on Proof-of-Stake technology. This will allow for high-speed and low-cost transactions.
The DISCIPLINA team understands that some students will not agree to provide full access to their personal data. Thus, they will be given the opportunity to deny access to their personal data either partially or fully. The data will be stored in private chains of educational institutions and public chains will only have the hashes of the data. This will ensure the reliability and security of the private data.
When you read the paragraphs above, you may ask yourself: what will happen if an educational institution decides to quit the network or if its equipment malfunctions? Students will always be able to access the data on their academic achievements, since they will have copies of all the data stored in the DISCIPLINA network. Thus, it will be easy to prove the authenticity of the data by accessing the old records in the public chain and checking the hashes.
