Title: Development of a Blockchain-Based Credentialing SDK Leveraging the Cosmos Ecosystem
This proposal outlines the creation of a comprehensive Software Development Kit (SDK) designed to facilitate the issuance, verification, and management of blockchain-based digital credentials for prominent educational and credentialing institutions.
1. On-chain Credential System: Leveraging the inherent robustness of the Cosmos blockchain, our strategy involves encoding digital credentials in a universally standardized JSON format. With Cosmos’ demonstrated scalability and data integrity, we are well-positioned to manage the vast ecosystem of digital credentials. Accredible alone has more than 60 million paid credentials.
2. Standardization: Aligning with existing standards like Mozilla’s Open Badges and MIT’s Digital Certificates, we propose to develop a cohesive, standardized JSON data structure, enabling seamless interaction with various issuers and external systems
3. User Interaction: The SDK will provide a simple and intuitive interface for issuers to interact with the blockchain, like creating, updating, or revoking credentials. Furthermore, the same interface should enable recipients to retrieve and verify their credentials.
4. Privacy: Since credentials often contain sensitive information, it’s important to take privacy considerations into account.We will try to utilize Zero-Knowledge Proofs ( as they become more mature) or other privacy-preserving techniques to verify credentials without revealing unnecessary details.
5. Updatability: To allow for the chaining of credentials, the SDK will facilitate updates to the credentials without sacrificing their integrity or verification. For instance, changing a surname after getting married should not invalidate the original credential but simply update it. The system will be designed to keep an audit trail of all updates.
As a key contributor to Accredible’s backend systems, my in-depth understanding of users’ needs will guide the design of an SDK that effectively addresses significant issues like privacy and updatability. By leveraging the capabilities of Cosmos, this project aims to spearhead a more secure, efficient, and transparent era of digital credentialing.
