Tasks
- Implement cutting-edge layer-2 blockchain technology (i.e. Perun, Erdstall or individual solutions)
- Consult and work with the team on use cases for partners (in IoT, energy, finance, etc.)
- Contribute to our applied research on blockchain technology
- Help design and implement various cryptographic protocols
- Implement our technology for the most-renowned blockchain ecosystems
Requirements
- Strong programming skills (Go, Rust, C++, Java or similar programming languages)
- You enjoy working on challenging tasks
- You are open to receiving and giving feedback and learning from others
Experience with the following topics is a plus:
- Knowledge of cryptographic protocols and blockchain technology
- Developing networking stacks
- Collaborative open source projects
- Agile projects using scrum
Benefits
- Be part of exciting open-source projects
- Good engineering practices (testing, CI, reviews, …). We <3 maintainable code.
- Learn state-of-the-art technology from experienced blockchain researchers and developers
- Flat hierarchies & flexible working hours
- Strong contacts to leading figures in the cryptocurrency space
- Lots of fun
We are looking forward to your application. Please don't hesitate to apply even if your are not a 100% fit to the description. Let's together realize the true power of decentralization.
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.
