Overview #
Blockchain technology forms the foundation of Blerify’s ecosystem, ensuring security, transparency, and decentralization.
By leveraging the LACChain blockchain network, Blerify delivers high-performance and compliant solutions for Verifiable Credentials, Vouchers, and other digital interactions.
Why Blockchain? #
Blerify utilizes blockchain to:
Ensure Data Integrity: Immutable records on the blockchain prevent tampering and fraud.
Enable Decentralized Identity: Blockchain-based DIDs empower users with self-sovereign identity.
Foster Trust: Transparent and verifiable transactions build trust among participants.
Enhance Security: Advanced cryptographic methods protect data and interactions.
Blockchain Infrastructure #
Blerify is built on LACChain, a regional blockchain network designed for high reliability and compliance with Latin American regulations. Key characteristics include:
Permissioned Network: Ensures that only authorized participants can interact.
High Performance: Optimized for low latency and high throughput.
Sustainability: Energy-efficient consensus mechanisms.
Compliance: Adheres to regional legal and regulatory frameworks.
Core Blockchain Features in Blerify #
- Decentralized Identifiers (DIDs):
DIDs are registered and managed on the blockchain. They provide:- Self-Sovereignty: Users control their identifiers without intermediaries.
- Interoperability: Standardized formats ensure compatibility across systems.
- Credential Anchoring:
Credential issuance and verification leverage the blockchain for:- Tamper-Proof Records: Credentials are anchored to the blockchain, ensuring authenticity.
- Efficient Verification: Blockchain facilitates instant and cost-effective credential validation.
- Tokenized Vouchers:
Vouchers are implemented as tokens on LACChain, enabling:- Real-Time Transactions: Users can redeem vouchers securely and seamlessly.
- Traceability: Full visibility into voucher issuance and redemption.
- Smart Contracts:
Smart contracts automate critical processes, such as:- Credential issuance and revocation.
- Voucher validation and redemption.
Blockchain Data Storage #
To maintain privacy and compliance, Blerify employs a hybrid storage model:
On-Chain Data:
DID registration.
Credential hashes for integrity verification.
Voucher token transactions.
Off-Chain Data:
User-sensitive information remains off-chain to ensure privacy.
Linked to the blockchain via cryptographic hashes.
Interaction with Blockchain #
Blerify interacts with the blockchain via API endpoints and SDKs. Developers can leverage these tools to integrate blockchain functionality into their applications.
Blockchain APIs: #
DID Registration:
Endpoint:
POST /blockchain/did/registerRegisters a new DID on LACChain.
Credential Anchoring:
Endpoint:
POST /blockchain/credential/anchorAnchors a credential to the blockchain.
Voucher Management:
Endpoint:
POST /blockchain/voucher/redeemProcesses voucher redemptions.
Example API Workflow: #
User creates a DID and anchors a credential.
The verifier scans a QR code linked to the credential.
The verifier’s system queries the blockchain to validate the credential.
Blockchain Security #
Blerify integrates advanced security measures, including:
Cryptographic Algorithms:
Hashing for data integrity.
Digital signatures for authentication.
Quantum-Resistant Encryption:
Preparing for post-quantum security threats.
Permissioned Access:
Restricted participation ensures system integrity.
Use Cases #
Credential Verification #
Credentials are securely issued and validated via the blockchain.
Example: Validating a diploma using the LACChain network.
Voucher Redemption #
Tokenized vouchers are redeemed through blockchain-verified transactions.
Example: A user redeems a meal voucher at a partner store.
Decentralized Identity #
Users manage their DIDs and associated credentials independently.
Example: Using a DID for authentication in a digital service.
