Sentinel is a decentralised, open-source cryptocurrency that prioritises internet privacy and security by facilitating global access to a virtual private network (VPN) powered by blockchain technology. Launched as part of the Cosmos ecosystem, Sentinel employs decentralised market principles to overcome the limitations of traditional centralised VPNs. Users can anonymously purchase and provide VPN services, ensuring privacy through a community-driven platform that eliminates third-party interference. Sentinel's architecture leverages a distributed node network, allowing individuals to own and deploy their own nodes to enhance network security, scalability, and reliability.
