Fogo ($FOGO): Uses a pure implementation of the Firedancer client to achieve record block times of 40ms. Its goal is to eliminate latency so that on-chain trading is indistinguishable from that of a centralized exchange like NASDAQ.
Vanar ($VANRY): Its main engine is Kayon, a decentralized inference system. It not only processes transactions quickly but also allows the network to "think" and analyze data in real-time for entertainment and logistics applications.
