Iron Fish is a new cryptocurrency that takes no shortcuts on privacy and usability. Privacy isn’t just important, it’s essential to crypto’s success. Our vision is for Iron Fish to become a shielded layer for many more assets, even ones on different chains, and provide a platform for true digital cash. A core belief at Iron Fish is that privacy and ease-of-use are not in opposition. Users and developers deserve both. Our codebase is TypeScript + Rust, so the world's 1M+ JavaScript developers can contribute. The current implementation is even compatible to run a full Iron Fish node directly in the browser in future iterations. We are looking for a Software Engineer to work on the core Iron Fish protocol and supporting tools. You will work collaboratively with our team members on developing new protocol features and focus on optimization, scale, and performance of a purely decentralized peer to peer (p2p) system. The Iron Fish team is made up of curious, passionate,...

At Matter Labs, we are building  zkSync : a blockchain scaling solution secured purely by cutting-edge cryptography. Our mission is to scale Ethereum to billions of users, fully preserving its most valuable properties — permissionlessness, trustlessness, and resilience, — in order to protect and enhance global economic freedom. We hold a strong opinion that zero-knowledge proofs (ZKP) are the only technology today that can achieve this goal. We are also proud to be the pioneer of the ZKP tech on Ethereum, and one of the few companies in the world with strong expertise in this field. Our contributions over the last 3 years include the first ZK rollup ever built, the first implementation of recursive ZK proofs on Ethereum, and the world’s first practical FPGA-based ZKP accelerator. Most recently, we launched a   zkEVM testnet , making zkSync the first ZK rollup capable of executing native Ethereum smart contracts. Across all hires we make at Matter Labs, regardless of...

About Heliax The primary project of   Heliax   is the   Anoma   protocol (implemented in   Rust ). Anoma is self-contained, self-sovereign and capture resistant, enabling private, asset-agnostic cash and private coordination among any number of parties. In addition to Anoma, Heliax works on open-source projects which are part of the Anoma ecosystem, including but not limited to research in cryptographic libraries such as the   MASP ,   Plonk   or   Ferveo   (written in Rust), and tools for high assurance validity predicates and arbitrary zero-knowledge circuits ( Juvix , written in Haskell). Heliax is a remote-first public goods lab which researches, develops, deploys, and maintains open-source protocols & mechanisms designed to serve the everyday needs of humanity. Using this, we build vertically integrated open-source products and networks that form coherent open systems which are capable of acting as an alternative to existing exploitative paradigms. With team...

About the Position We are hiring ZK Compiler Engineer for OpenZL ( https://github.com/openzklib/openzl/blob/main/proposal.md ). OpenZL is a suite of software tools for building ZK applications. At its core sits ECLAIR, the circuit description language, which allows developers to build proof-system agnostic applications and leverage custom optimizations at any level of their program. ECLAIR is an embedded domain specific language in Rust and features procedural macros heavily in its design to reduce boilerplate and create generic code. OpenZL also features backends for cryptographic libraries that implement ZK proof systems, and other cryptographic protocols that plug into ECLAIR. Building these macros and cryptographic backends requires advanced knowledge and experience with the Rust compiler and its macro ecosystem but also experience with generics, traits, and the best-practices of Rust interface design to make all of these pieces work together. Who You Are...

Lurk is an in-development, Turing-complete programming language for recursive zk-SNARKs. It is a statically scoped dialect of Lisp, implemented in Rust to support evaluation, proving, and verification in zero-knowledge. Since Lurk is Turing-complete, it can be used (within resource limits) to make and prove arbitrary computational claims without the constraints of traditional fixed-circuit SNARKs.  A “Rust Cryptography Engineer for Lurk” will help drive the development of the Lurk programming language. The ideal candidate for this job will have experience writing zk-proofs or zk-proof adjacent software in Rust. You can learn more about Lurk at https://github.com/lurk-lang and the Rust implementation at https://github.com/lurk-lang/lurk-rs . Job Responsibilities... Work closely with the current Lurk engineering team, a technical program manager, and core collaborators to support the growth of the language Invest significant time in learning and understanding the...

Gnosis Chain is the product of the merger of Gnosis and xDai. As one of Ethereum’s earliest sidechains, Gnosis Chain has quiet but significant real world usage and will embark on an aggressive technical roadmap with the objective of accelerating Ethereum. Gnosis Chain is also where Ethereum’s colorful and quirky spirit lives on, as the original home that incubated many defining projects like POAP, Burner Wallet, Dark Forest, and Perpetual Protocol.  Gnosis Beacon Chain launched in November of 2021 and will merge with Gnosis Chain when Ethereum merges. GBC has over  100k validators  and aims to be the third most decentralized blockchain. Gnosis Chain currently does not have a trustless bridge, which we are looking to remedy. A proposal by the 0xparc team for a zk light client based bridge  passed in July  and we know that other teams are working on trustless bridges as well. What you will do Keep up to date with the bridge design space and open research...

Polygon zkEVM is the first open-source zk-Rollup providing complete EVM opcode equivalence for a frictionless user experience and the security of Ethereum. A zk-Rollup is a layer 2 construction on top of Ethereum that solves its scalability through mass transfer processing rolled into a single transaction. The "zero-knowledge proof" (ZK) technology is used to present and publicly record the validity and correctness of the rolled transfers processed on the Ethereum blockchain. By storing just the proof and the compressed data of a batch of transfers, the efficiency and the throughput of the network is multiplied. We offer remote and flexible work. You can expect a warm welcome from a friendly and international team that will support you in your personal and professional growth. This is an exciting opportunity to take an active part in the blockchain space and contribute to the decentralization of the future. We're looking for a Golang developer to join...

Opening paragraph Disruption is changing the way the world works. It’s happening quickly. And it’s creating opportunity, if you can keep up and even get ahead of it. That’s why we’ve established a dedicated Global Innovation team focused on understanding external forces changing our world and how to do things differently in 6 months, 3 years, 10 years and beyond. In this shifting landscape, we are challenging ourselves to embrace disruption and think differently for our clients. How? By combining the experience of our global Tax, Accounting, Advisory and Transactions professionals (the “suits”) with start-up thinking (the “jeans”). This “suits+jeans” approach applies an entirely new mindset for today's challenges. Our global network of EY teams and innovation centers are creating powerful ideas for organizations and ourselves, especially around opportunities coming from artificial intelligence, blockchain, robotics and data and analytics. The opportunity...
