How to Contribute

Your contribution matters!
Nebulas aims for a continuously improving ecosystem, which means we need help from the community. We need your contributions! It is not limited exclusively to programming, but also bug reports and translations, spreading the tenets of Nebulas, answering questions, and so on.

1. Code & Documentation

1.1. Mainnet Development

Besides programming, mainnet development is still ongoing and needs the help of the community to tackle challenging problems in the blockchain industry. For instance, we need to design manipulation-resistant mechanisms for blockchain, formally verify the new consensus algorithm, improve security of the Nebulas mainnet, apply new crypto algorithms to Nebulas, etcetera.

We are so excited to devote ourselves to blockchain and to see how blockchain can improve people’s lives. We want to share this exciting experience with the whole community. Thus, we call upon developers!
