About Waku
We are building Waku (Waku.org) as a public good infrastructure. Waku is the messaging layer of Web3.
It is a decentralized, censorship-resistant, privacy-preserving communication network that enables anyone to send and receive messages without worrying about surveillance or deplatforming.
We are developing 3 open source implementations of Waku:
- Nwaku.https://github.com/waku-org/nwaku: the reference implementation and service node
- Js-waku,https://github.com/waku-org/js-waku: for the browser
- Go-waku:https://github.com/waku-org/go-waku: to integrate as a library in native applications
We are enabling Ethereum builders to create new projects with a fully decentralized architecture, think dApp to Wallet notifications, NFT marketplaces, censorship-resistant chat, layer-2 decentralization and more.
We are looking for a Software Engineer who is passionate about Ethereum, and decentralization. And who would relish the opportunity to champion Waku to other Web3 projects and developers.
The Role
This role will be part of Vac’s Secure Messaging (SeM) team. We research and design modular p2p protocols for scaling, secure, private, anonymous, and censorship-resistant communications. The main focus is Waku, the communication layer for Web3.
Key Responsibilities
- Research and develop open P2P protocols for secure messaging.
- Research efficient, scaling solutions for P2P communications.
- Build incentivized, distributed systems.
- Use a layered protocol approach that is mindful and explicit about what it requires, what it provides, under what threat models, and with what trade-offs.
- Combine cryptoeconomics and traditional technologies to create a sustainable, scalable, distributed, and fault-tolerant system.
- Use libp2p to build application-level protocols.
- Interpret and implement solutions based on academic research.
- Provide feedback on overall design decisions, and participate in code reviews.
- Write Nim code.
You ideally will have
- A passion for blockchain technology, privacy-preserving technology and decentralization.
- A strong academic background.
- Experience with encryption and key exchange mechanisms.
- Experience with low level/strongly typed languages (C/C++/Go/Rust).
- Experience building networking-heavy applications and p2p networking specifically.
- Familiarity with message propagation in loosely connected networks.
- Familiar with p2p building blocks such as gossiping, routing and discovery (DHTs), and Nat traversal.
- Experience designing incentive systems and writing/deploying smart contracts in Ethereum.
- A Master’s degree in Computer Science with a focus on computer networks.
- A strong alignment to our principles: https://status.im/about/#our-principles
Bonus points if
- A PhD degree in an area related to computer networks.
- Contributed to a blockchain-related, open source project.
- In in the Ethereum community.
- Experience with cryptography such as OTR, X3DH, Noise protocol.
- Experience with Nim.
- Experience with off-the-shelf networking stacks such as libp2p / devp2p.
[Don’t worry if you don’t meet all of these criteria, we’d still love to hear from you anyway if you think you’d be a great fit for this role. Just explain to us why in your cover letter].
Hiring Process
- Intro call with our People Ops team
- Interview with member of the Waku team
- Pair programming session with member of the Waku team
- Interview with Program Lead
Compensation
We are happy to pay in any mix of fiat/crypto.
What is the meaning of Layer 2?
Layer 2 in the context of cryptocurrency and blockchain technology refers to a secondary framework or protocol that is built on top of an existing blockchain system (the main chain or Layer 1)
The primary purpose of Layer 2 solutions is to solve the scalability and speed issues that many blockchains face, especially those that have become popular and heavily used, like Ethereum
Here are the key aspects of Layer 2 solutions:
- Scalability Enhancement: They help in scaling the main blockchain by handling transactions off the main chain. This reduces the burden on the main chain, allowing for faster and cheaper transactions.
- Types of Layer 2 Solutions: There are various forms of Layer 2 solutions, including state channels, sidechains, plasma chains, and rollups. Each has its own mechanism for interacting with the main chain and handling transactions.
- State Channels: These involve two parties engaging in numerous transactions outside of the main chain, which are then consolidated into a single transaction. This is especially useful for situations where multiple transactions occur between the same parties.
- Sidechains: These are separate blockchains that are connected to the main chain via a two-way peg. They operate independently and can have their own consensus mechanisms but are secured by the main chain.
- Plasma Chains: Plasma chains are similar to sidechains but with a more hierarchical structure. They report back to the main chain regularly and are optimized for mass transaction handling.
- Rollups: Rollups process and store transaction data on a sidechain but post transaction data to the main chain. They come in two varieties: optimistic rollups and zk-rollups, each with its own method of transaction verification.
- Security Considerations: While Layer 2 solutions are generally secure, they can have different security models compared to the main chain. This is an important consideration for users and developers.
- Impact on User Experience: For end-users, Layer 2 solutions can greatly improve the experience by reducing transaction fees and increasing transaction speeds.
- Adoption and Development: Many blockchain projects are actively developing Layer 2 solutions to enhance their networks. This is an ongoing area of innovation in the blockchain space.
