Blockchain-backed systems for identity, permissions, document access, and loan management — designed for regulated, high-trust environments where auditability and correctness are non-negotiable.
Government and institutional systems handling identity, loans, and sensitive documents face persistent structural issues: centralized databases, weak auditability, manual verification, and unclear access control.
The challenge was not using blockchain for storage — it was designing a system where identity, permissions, and actions could be independently verified, enforced, and audited.
Smart contract design for identity, RBAC, documents, and loan lifecycles.
Frontend, backend SDKs, encryption flows, and admin interfaces.
End-to-end identity, permission, and access lifecycle design.
Separate contracts for identity, role-based access control (RBAC), loans, and document references—each with clear responsibilities and deterministic behavior.
On-chain role enforcement with deterministic access rules. Users cannot bypass permissions—they're enforced at the protocol level, not in application logic.
Files encrypted with AES, keys secured via ECIES using Ethereum public keys. On-chain references only—sensitive data never touches blockchain.
JavaScript SDK abstracting blockchain complexity. Developers work with familiar APIs while permissions and crypto happen transparently under the hood.
Aadhaar + OTP flows designed for government and institutional use. Modern React interfaces hide blockchain complexity from end users.
File → AES encrypt → ECIES key wrap → on-chain ref → access check → decryption → user
Tamper-resistant identity and permission enforcement.
Cryptographic enforcement reduced reliance on centralized systems.
A base platform for future regulated governance systems.
MAHA DISHA demonstrates Technakama’s ability to design blockchain systems where trust, identity, and permissions are enforced at the protocol level — not bolted on later. This is blockchain used where it actually makes sense.
