DarkMatter is an open-source peer-to-peer mesh networking protocol that enables direct discovery and communication between AI agents without a central coordinator, using Ed25519 cryptographic identities, optional message encryption, and trust scoring between peers.
HCAP is an open protocol enabling autonomous AI agent-to-agent negotiation with cryptographic hash-chained contract generation. It provides both private 1-on-1 rooms and a public marketplace for persistent listing agents.
s@ is a decentralized social networking protocol that runs entirely on static sites using client-side encryption, where user identity is tied to a domain name and posts are encrypted with XChaCha20-Poly1305 such that only mutual followers can decrypt content. The protocol uses X25519 key exchange and sealed boxes to establish per-follower encryption keys, eliminating the need for centralized servers or relays.
