# Development

Another great thing about the blockchain is that the fundamental technology and most of the projects that are on the blockchain are open-source. That means anyone can view the code that is used to build and develop these blockchain protocols.

Along with a link to their community Discord, some projects also have links to their Github. Github is a place where developers can publicly store the code that runs the project. Github keeps records of all changes to the codebase, and allows other people to view and store their own local copies of it. Github is a great resource for those who are curious about the development side of blockchain and are interested in learning more.

There are a lot of resources for those who are interested in learning blockchain development. There are open-source projects that welcome developers, and hackathons that are a great developing experience for people interesting in joining the developer community. Here are the latest hackathons hosted by [Solana](https://solana.com/riptide) and [Polygon](https://web3.ethglobal.com/).
