Credify
Credify is a blockchain-based system for issuing and verifying academic credentials using cryptographic signatures and selective disclosure. It enables institutions to issue digitally signed credentials and allows individuals to present verifiable proof of qualifications without exposing unnecessary personal data.
Credify applies decentralized identity principles to academic records. Credentials are structured as signed digital objects and anchored to a blockchain network for integrity.
Verification is performed using cryptographic proofs rather than manual confirmation from issuing institutions.
The system supports selective disclosure, allowing credential holders to reveal only specific attributes, such as a degree or completion status, while keeping the rest private.
Academic credential verification typically relies on document exchange and direct communication with institutions.
• Verification processes are slow and inconsistent • Certificates can be forged or altered • Individuals often share more data than required
Digital formats improve accessibility but do not fully address authenticity or privacy concerns.
Credify addresses these issues using blockchain-backed records and cryptographic validation.
Credify follows a three-entity model:
• Issuer – institution that creates and signs credentials • Holder – individual who stores and controls credentials • Verifier – entity that validates credential authenticity
Credentials are issued as signed data structures. A hash or reference is recorded on-chain for verification.
Credential issuance Institutions generate credentials and sign them using cryptographic keys. A reference may be anchored on a blockchain.
Storage and ownership Credentials are stored in a digital wallet controlled by the holder.
Selective disclosure Holders can share only required attributes without revealing the entire credential.
Verification Verifiers validate credentials by checking signatures and blockchain records, without contacting the issuer.
Credify integrates:
• ⛓️ Ethereum or other EVM-compatible networks • 📜 Smart contracts • 🔐 Cryptographic signature schemes • 🧠 Zero-knowledge proof for selective disclosure • 🌐 Web-based or wallet-based interfaces
• Academic degree verification • Recruitment and background checks • Scholarship validation • Certification and training records
• Tamper-resistant credentials • Fast verification without intermediaries • Reduced data exposure • Interoperability across systems
• Requires adoption by issuing institutions • Dependence on blockchain infrastructure • Complexity of cryptographic implementation
Credify is under development. Core credential issuance and verification flows are implemented, with selective disclosure features in progress.
• Blockchain • Verifiable credentials • Decentralized identity
