Frequently Asked Questions – Credential Management Platform

Government Technology Agency of Singapore (GovTech Singapore – tech.gov.sg) developed the OpenCerts in cooperation with the OpenCerts Consortium.

OpenCerts is the umbrella trademark under which GovTech Singapore released the open-source schema and tools for publishing and generating cryptographic protections for educational credentials.

Blockchain technology significantly reduces the barrier to entry of publishing cryptographically protected educational credentials, as compared to currently existing costly proprietary software.

The Ethereum Blockchain is a publicly available distributed ledger based on blockchain technology. It is the blockchain network with the most extensive developer base, as well as having a large number of participants securing the network. As a result, there is no need for the Issuing Organizations to run or support services to verify certificates issued on OpenCerts.

Academic records of the certificate and personal data are not published on the blockchain. A hash is generated from the certificate and is used to prove that the certificate is legitimate. Since the hash is the only information published into the blockchain, no personal data can be obtained from content on the blockchain.

A hash-based message authentication code that cryptographically certifies that the content of the certificate has not been altered.

A Cryptographic Hash is a mathematical algorithm that maps input data of any length into a bit string of a fixed length (the “hash”). It is deterministic, meaning the same input always results in the same hash. It is a one-way function, which is practically infeasible to invert.

The modified certificate will fail validation and show up as having been tampered with.

Yes, the certificate file can trivially be duplicated. However, the recipient’s data in the certificate cannot be altered without failing our verification process. Thus the person doing the verification must ensure that the recipient indicated in the certificate is the entity presenting the certificate.

Knowledge Catalyst is a Singapore-based Company with a focus on using technology to address the widening gaps of equitable learning and the future of works. We address the real challenges around getting access to quality educations, acquiring and applying critical knowledge that, in turn, increases competitiveness and productivity at work.

We collaborate with the GovTech Singapore and the OpenCerts Consortium to offer the Credential Issuance and Management Platform and Services for organizations to issue non-tampered blockchain records that ensure the authenticity and verification of the documents.

We host our infrastructure on Amazon Web Services (AWS) in Singapore. AWS was the first global cloud service provider to achieve the Singapore Multi-Tier Cloud Security Standard (MTCS SS 584) Level-3 (CSP) certification for the Singapore region.

This certification gives organizations the clarity to utilize AWS to host and process their highly confidential data.

Yes, you can use pre-designed or custom-designed templates that are responsive to multiple devices and screen sizes.

We support various methods for certificate issuance, via the web-based editor, through the upload of a CSV file, or API integration with your current system.

Each certificate issued on OpenCerts by Knowledge Catalyst will show a QR Code and a Blockchain Record.

For easy visual validation, you can scan the QR code using your phone camera – and it will show the certificate stored on the blockchain record.

For bulk validation, we suggest integrating through the API integration with your system.
