PhD internships


The Synnax team aims to formally verify as much of the Ethereum ecosystem as we can: Solidity smart contracts, Cairo smart contracts, protocols, compilers, etc. We work with both external clients and other teams at Nethermind. We develop and apply formal verification tools and leverage the Lean proof assistant to formally verify smart contracts, compilers, etc.

Skills that you will use and learn in the Synnax team include but not limited to:

  • Publishing and presenting research results both internally and externally
  • Collaborating with both internal and external customers and the teams responsible for the implementations being verified
  • Writing formal specifications in Lean
  • Writing formal verification tools (SMT checkers, Horn solvers, proof assistant libraries, etc)
  • Formally specifying programming languages. (Solidity, Yul, EVM, Cairo, etc)
  • Formal specifications of distributed systems
  • Cryptography, Zero-Knowledge Proofs and Abstract Algebra



In the Nineveh research team, we investigate cryptography developments to make Ethereum a better, safer and more private place. Some exemplary projects we are engaged in are:

  • Hybrid proof systems from SNARKs and STARKs. In this project, we combine techniques from SNARKs and STARKs to build hybrid proof systems enjoying the bests of both worlds. SNARKs allow for short (constant-size) proofs and have efficient verifiers, on the other had, they require trusted setup. zkSTARKs are transparent (don’t rely on a trusted setup) and have efficient prover while paying the price of longer proof size (logarithmic to the size of the proven statement) and verifier’s complexity. We investigate use of STARK-related primitives like FRI to give zkSNARKs more efficient provers and reduce security assumptions used. In the nearest future we plan to implement our hybrid schemes to show the world concrete efficiency gains our approach brings.
  • Secure storage for mnemonic keys. The common problem of using secret keys is that they may be stolen or lost, causing for example, losing access to staked funds. Here, we build an application that allows users to securely distribute the key into so-called shares such that only large enough set of the shares can be used to reconstruct the secret and someone who knows too few secret’s shares learns nothing. We achieve that by using Shamir’s secret sharing scheme. Importantly both the secret and the shares are represented by easy to remember mnemonic.
  • Security analysis of proof systems. In this project, we analyse security properties of existing zkSNARKs to verify whether they are sufficiently secure for such a complex environments that blockchains are. To that end, we use provable security methods. Additionally, we analyse existing zkSNARKs and name their security gaps. We show where efficiency-oriented efforts make proof systems unusable due to security vulnerabilities.
  • Towards more efficient and secure polynomial commitments. Polynomial commitment schemes are going to lay the ground for Ethereum’s data availability in the future. Hence, one of our research task is to investigate novel polynomial commitment schemes that are better than Kate et al commitment scheme in terms of security and efficiency.
  • Towards more fair MEV. On of the potential security measure one can take to mitigate malicious MEV extraction attacks is by obfuscating submitted transactions. In this project, we investigate use of privacy preserving tools to assure more fair MEV.

Our team is looking for two kinds of people:

  • Cryptography enthusiasts who would enjoy analysing, breaking and designing cryptographic schemes.
  • Engineers with some background in cryptography who enjoy making proof of concepts of novel cryptographic protocols, extending cryptographic libraries, and finding vulnerabilities in existing implementations.

Skills that you will use and learn at the Nineveh research team include but not limited to:

  • basic algebra
  • cryptography – provable security, cryptographic protocols (esp. zero-knowledge ones)
  • MEV
  • distributed systems
  • C++ / Rust / Python

Here’s what some of our current interns have to say:

Not only it gives me a chance to learn a lot but also, I’ll be able to help in solving real world problems”* Carmen Irene Cabrera Rodríguez, Cairo and Layer 2 Research Intern, Nubia team
  • “The Nethermind internship is like selling your soul to the devil. You don’t know what you’re getting yourself into at first, but by doing it you get some pretty rad powers with which to flex on mere mortals”* Kristof Gazso, Ethereum and MEV Research Intern, MEV and Ethereum 1 team
  • “Working at Nethermind is nothing short of a journey, every day is a new challenge to learn and grow. The projects are incredibly exciting, and the dedication and grit of the team is unstoppable”* Guilherme Heise, Blockchain Data Engineering Intern, Data team
  • “I recently started an internship at Nethermind, and I can say that, it is one of the best professional experiences I have ever had. Wonderful co-workers, projects on blockchain, DeFi, Ethereum and much more. Definitely a great place to grow, both professionally and personally”* Marcos Maceo, Blockchain Engineering Intern
  • “If you are interested in blockchain, this is a great opportunity. Nethermind is an excellent place to be an intern. There are a lot of interesting projects and everyone want to help you. The best place to learn.”* Mauricio Perdomo Cortés, Blockchain Engineering Intern, Venice team
