Point Network - Blockchain Architect (Remote)
About us
We're developing Web 3.0 decentralized internet, with decentralized storage and Web 3.0 browser. It will allow all kinds of dApps to be created - decentralized, censorship-resistant Facebook, Twitter, Reddit, end-to-end encrypted email and instant messenger, and a lot more. We participated in the Solana Hackathon and made the Honor List recently. Find out more about us here: https://pointnetwork.io
About the position
You'll be working side by side with a team of developers to bring our Web 3.0 project to life. Our goal is to launch a public beta in Q1 2022. Alpha has been launched with an amazing response. In this role you will conceptualize and contribute to blockchain-enabled initiatives, collaborating with specialists inside and outside of the company. The ideal candidate will have a strong background in blockchain architecture, a passion for digital assets, and a point of view with respect to the future of decentralization.
Responsibilities:
â—Ź Discuss project aims with the team. â—Ź Working with the developers on projects. â—Ź Collaborate with teams to understand the requirements, identify solutions, propose ideas and provide technical thought leadership. â—Ź Document the overall systems/application architecture.

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.
