Network Security and Applied Cryptography Projects 2025/26

Hitesh Tewari (email | all projects)

I lead the Applied Cryptography Research Lab (https://www.appliedcryptolab.com) at Trinity College Dublin. Our research group works with a number of ledgers such as Hyperledger Besu, Ripple’s XRP Ledger (XRPL), Substrate, Zcash etc. I have a number of projects on offer as outlined below. You will need to become familiar with some advanced cryptographic primitives and networking techniques during the course of the project. You will also need to quickly get up to speed on the specific ledger codebase that you will program your architecture and prototype on.

  1. Redactable Blockchain with Post-Quantum Cryptographic Guarantees
  2. zkBridge for Cross Chain Transactions
  3. XRPL with Halo2
  4. XRPL with Plonky2/HyperPlonk
  5. XRPL with zkRollups
  6. Adding Smart Contract Functionality into the XRPL
  7. Botan Integration into the XRPL
  8. zk-STARK Integration into the XRPL
  9. Interoperability of Blockchains Using the Cosmos Platform
  10. Sharded Blockchains
  11. PQC Integration into Substrate
