Hi, my name is
Vineet Pant.
Senior Software Engineer.
Senior software engineer with 13+ years of experience building secure, decentralized systems. I focus on core development, self-sovereign identity (SSI/DID), and systems programming in Rust, TypeScript, Java, and C.
01.About
I'm a senior software engineer with over 13 years of experience building secure, decentralized systems. My work spans Ethereum core protocol development, self-sovereign identity, verifiable credentials, hardware wallets, and key management.
Most recently I was selected for the Ethereum Protocol Fellowship (Cohort 6), where I built a proof-of-concept of EIP-7745 (Log Value Index) in the Nimbus execution client. Before that I spent four years writing Rust for decentralized identity SDKs, and earlier worked across identity and security solutions, including key management, access control, and identity systems such as UIDAI's Aadhaar.

03.Selected Work
MyID: Secure Digital Identity Wallet
A self-sovereign identity wallet for India (a Veriguard product) that lets people securely store, manage, and share documents, credentials, and business cards with bank-level encryption, while letting enterprises issue and verify W3C verifiable credentials. It is built on a Hyperledger Indy stack with Credo (Aries protocol) agents, DigiLocker and Aadhaar eKYC onboarding, and zero-knowledge selective-disclosure proofs. I am currently the architect and a contributor on the platform, working on the mobile wallet, Credo agent services, and the Indy trust layer.

- Verifiable Credentials
- Zero-Knowledge
DVRPC: Decentralized Verified RPC
A drop-in replacement for standard Ethereum RPC that returns cryptographically verified responses instead of blindly trusted ones, addressing the centralization of Ethereum infrastructure. It pairs a light client that derives a consensus-verified state root with EIP-1186 Merkle-Patricia-Trie proofs verified against that root, so clients only receive data that provably matches on-chain state, with no token required. As the sole author, I built the JSON-RPC server, light client integration, proof fetching, and the MPT proof verification engine.

- MPT Proofs
EIP-7745: Log Value Index
A proof-of-concept, SSZ-based log value index in the Nimbus execution client, built as part of the Ethereum Protocol Fellowship, exploring how bloom filters could be replaced with a cryptographically verifiable indexing system. I prototyped the LogIndex data structure with FilterMap bitmap organization, moved log storage to SSZ serialization with deterministic value-to-position mapping, and added 256-byte epoch summaries to the block processing pipeline. Tested in a Kurtosis devnet.

Vade SDK: SSI / DID
An open-source SSI/DID SDK and microservices in Rust and TypeScript, built at Blockchains over four years. I implemented DIF specifications, DID communication and Verifiable Credential / Presentation protocols, TypeScript microservices exposing DID/SSI to web and mobile apps, and Rust bindings for C and Java.
- Rust
- TypeScript
- NestJS
Identity & Data Management POC
Used enterprise blockchain to establish trust among organizational stakeholders and prevent fraud, with hardware wallets linking and proving identities of people in critical roles and PKI for authentication and attestation. I built the hardware-wallet app and the Haskell key-management components.
- Haskell
- C
- PKI
Aadhaar Registered Biometric Devices
Worked on UIDAI's Registered Device solution, where biometric devices are manufactured to prevent replay of stored biometrics. I built device key management against a vendor HSM server and authored the specification for device-to-server communication.
- C
- Java
- HSM
MasterCard EMV: Biometric
Added a biometric security layer to EMV cards for storing and verifying biometric data on-card. I implemented an APDU library for smart-card communication in Java for Android applications.
