PKT

PKT Network (PKT) claims to be the world's first hard-bandwidth blockchain and decentralized Internet Service Provider (ISP). PKT uses the open-source mesh networking protocol called cjdns to optimize traffic routing and provide free VPN. PKT enables network users to share access to the Internet and monetize their unused bandwidth.

PKT blockchain is based on Bitcoin's codebase, but replaces Bitcoin's SHA-256 hashing algorithm with PacketCrypt, the first-ever bandwidth-hardened proof-of-work. PKT blockchain was created to economically incentivize nodes to become internet service providers of the PKT network.

Together with the native mined coin PKT Cash, the project aims to demonopolize the global information space and allow users to access internet data without restrictions from centralized intermediaries.

PKT Cash serves as a reward for users who provide bandwidth to other nodes in the network, and can be used to get VPN through Anode VPN, PKT's VPN marketplace, and then pay Internet company bills through PKT pal, PKT's service for paying bills.

PacketCrypt and the PKT blockchain were both launched in August 2019. The PKR coin went live in March 2022.
