Note: Thank you for your interest in our internship program. We have had high numbers of people showing interest and we are extremely humbled by this. Due to high demand, we only have limited spaces for the next few months and we will only be interviewing and hiring the top candidates. This may change in the future.

Please note that we will continue to accept applications and will interview only the candidates that are the best fit for Nethermind. We have already reached our quota for December and January. We look forward to reviewing your application and potentially welcoming you to our team.

If you don’t get picked the first time around don’t get discouraged! We are incredibly lucky to get extremely skilled and talented people applying and it often is a difficult choice to make. Just continue learning and developing your skills and try again in a few months.

Nineveh (Cryptography Research)

The Cryptography Research team at Nethermind leverages both theory and implementations to improve, build or break protocols related to cryptography and blockchain technology. The team's projects include zero-knowledge proofs, Distributed Validator Technology, decentralized identity/verifiable credentials, liquid staking on Ethereum, and non-deterministic programming (specifically, Cairo programming).

Skills that you can use and learn working with the Cryptography Research team include:

Cryptography
Rust/C++/Cairo programming
Understanding of blockchain consensus protocols
Technical due diligence on novel blockchain projects
Communicating research concepts through technical writing
Smart-contract implementations, especially those related to zk-proofs
Theoretical analysis and implementation of both STARKs and SNARKs
Abstract algebra and its applications to cryptography and zero-knowledge
Understanding and designing building blocks in Ethereum, such as Distributed Validator Technology, decentralized identity, and liquid staking, among others

Our team is looking for two kinds of people:

Cryptography enthusiasts who would enjoy analyzing, 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.

A few of the projects Nineveh worked on:

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 efficient verifiers; on the other hand, they require a 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 the use of STARK-related primitives like FRI to give zkSNARKs more efficient provers and reduce security assumptions used. In the near future, we plan to implement our hybrid schemes to reveal the concrete efficiency gains our approach brings.
Secure storage for mnemonic keys. A common problem with using secret keys is that they may be stolen or lost, causing, for example, the loss of access to staked funds. We are building an application that allows users to securely distribute the key into so-called shares. Only a large enough set of shares can be used to reconstruct the secret, and someone who knows too few secret shares learns nothing. We achieve that by using Shamir's secret sharing scheme. Notably, both the secret and the shares are represented by an easy-to-remember mnemonic.
Security analysis of proof systems. In this project, we analyze the security properties of existing zkSNARKs to verify whether they are sufficiently secure for such complex environments as blockchains. To that end, we use provable security methods. Additionally, we analyze existing zkSNARKs and name their security gaps. We show where efficiency-oriented efforts make proof systems unusable due to security vulnerabilities.
Sybil resistant operator onboarding. Liquid staking protocol’s efficiency and security relies on operators who take the stake provided by users and run validators for them. Various staking protocols have various operators onboarding procedures. Some require DAO approval, some require the prospective operator to put a significant bond. It is also important that the set of operators is decentralized, and no operator can be a single point of failure or can harm the protocol. Hence, it is of utter importance to make sure that no operator controls more stake than allowed. In this project, we aim to design a Sybil-resistant permissionless operator onboarding mechanism. Here Sybil resistance means that it is difficult for a dishonest party to create and maintain multiple operators to control more than the allowed amount of the stake.
Towards efficient private state contracts. Currently deployed zk-based private-state smart contracts are limited by the fact that they cannot make state transitions that would involve two more more private states. E.g., it is currently infeasible to make a private exchange protocol, as such protocol would require two parties to compute jointly a transformation of their states. To make this possible, secure multi-party computation (MPC) are used. Unfortunately, combining MPC and ZKP naively, results in a protocols which efficiency is dubious. In this project we aim to find a novel method of combining these two primitives to make the shared state computation as efficient as possible for the widest class of functions.
zkSNARKs for CPUs. Virtually all existing zkSNARKs are defined for relations over finite fields. On the other hand, computers perform operations over rings, more precisely $\mathbb{Z}/2^{64}\mathbb{Z}$. In this project, we aim to propose a new zkSNARK for relations defined over rings to benefit from the possibility of performing operations in a way native to CPUs.
New lookup arguments. Since zkSNARKs are defined over finite fields (bigger than $\mathbb{F}_2$), making arguments about binary relations is relatively inefficient. To improve the efficiency of such operations lookup arguments are used. That is, instead of showing that some binary operation has been performed correctly, the prover shows that the relation’s inputs and outputs are in a precomputed table. Unfortunately, most lookup arguments rely on trusted setup, what make them useless for transparent (i.e. trusted setup-less) zkSNARKs. In this project we aim to provide more efficient transparent and non-transparent lookup arguments.
