It also has a built-in routing system that uses a distributed hash table (DHT) to find the most efficient route for data transmission, further increasing security and privacy.
One of the main benefits of CJDNS is that it allows for the creation of private, community-run networks. This allows users to communicate with a group of trusted individuals without the need for centralized infrastructure. This can be particularly useful for communities that need to communicate securely and privately, such as activists or journalists.
CJDNS is also open-source, meaning that the source code is publicly available for anyone to review and modify. This transparency allows users to verify that the protocol is secure and that there are no hidden backdoors or vulnerabilities. It also encourages community participation in the development of the protocol and allows users to customize it to suit their needs.
