Base

The base network uses the OP stack software, which is open source and publicly available; So users can fork the main chain and create their own version. Since the base network was created by the development team of the Coinbase exchange, it has a direct connection with other products of this exchange.

The base network being open source means that its code is publicly available for anyone to inspect, modify, and use. This transparency fosters collaboration, innovation, and community-driven development. Users can indeed fork the main chain, creating their own versions with custom features or adjustments.
