As the world is moving towards new technology, Web3 is the most trending of them. Developers are learning this new technology very fast, many companies are also shifting towards decentralized blockchain technology. To become a good web3 developer one need good skills related to tech, and for that, they will need practical knowledge of web3 technologies. Like working on or making projects based on blockchain.
In this article, I am going to share ** Some Useful GitHub Repositories you can contribute** to and enhance your practical knowledge of web3 technologies.

6. Nucypher
A decentralized threshold cryptography network focused on proxy reencryption.
A decentralized cryptological network offering accessible, intuitive, and extensible runtimes and interfaces for secrets management and dynamic access control.
The NuCypher network provides accessible, intuitive, and extensible runtimes and interfaces for secrets management and dynamic access control.
- Accessible - The network is permissionless and censorship-resistant There are no gate-keepers and anyone can use it.
- Intuitive - The network leverages the classic cryptological narrative of Alice and Bob (with additional characters where appropriate). This character-based narrative permeates the code-base and helps developers write safe, misuse-resistant code.
- Extensible - The network currently supports proxy re-encryption but can be extended to provide support for other cryptographic primitives.
Access permissions are baked into the underlying encryption and access can only be explicitly granted by the data owner via sharing policies Consequently, the data owner has ultimate control over access to their data At no point is the data decrypted nor can the underlying private…

This Next.js app is designed to be used with the Figment Learn Pathways, to help developers learn about various blockchain protocols such as Solana, NEAR, Secret, Polygon and Polkadot!
👋🏼 What is learn-web3-dapp?
We made this decentralized application (dApp) to help developers learn about Web 3 protocols.
It's a Next.js app that uses React, TypeScript and various smart contract languages (mostly Solidity and Rust).
We will guide you through using the various blockchain JavaScript SDKs to interact with their networks. Each protocol is slightly different, but we have attempted to standardize the workflow so that you can quickly get up to speed on networks like Solana, NEAR, Polygon and more!
