The underlying protocols and networks that make privacy possible: zero-knowledge proof systems, mixnets, and privacy-preserving computation.
Arcium is a decentralized confidential computing network that enables trustless encrypted computations over encrypted data using Multi-Party Computation. Built on Solana, it provides developers with MXEs—configurable MPC execution environments—and Arcis, a Rust-based DSL, to build privacy-preserving applications for AI, DeFi, and DePIN without exposing underlying data.
Beldex is a privacy blockchain network that combines Monero-based cryptography with a decentralized masternode infrastructure to enable private digital transactions and applications. The BDX coin powers transactions, staking, and network utilities across the ecosystem, which includes encrypted messaging, a decentralized VPN, a privacy browser, and a naming service.
GhostWareOS is a full-stack privacy layer for Solana that anonymizes user activity across payments, communications, and identity. Using zero-knowledge proofs and HPKE encryption, it provides GhostPay for private transactions hiding sender, receiver, and amount; GhostMask for generating communication aliases; GhostRelay for stateless encrypted messaging; and GhostScrub for revoking risky on-chain token approvals. The GHOST token redistributes 100% of protocol fee revenue to holders.
MagicBlock is a real-time infrastructure layer for Solana that enables low-latency, fee-free, and privacy-preserving application experiences via Ephemeral Rollups. Its Private Ephemeral Rollup (PER) uses Trusted Execution Environments (Intel TDX) for privacy-preserving computation without bridging assets off Solana. Designed for games, DeFi, and high-frequency use cases, it achieves sub-50ms end-to-end latency with 1ms block times while keeping applications fully composable with Solana's existing state and programs.
Nillion is a decentralized secure computation network that enables privacy-preserving storage and processing of sensitive data without decryption. Using Multi-Party Computation, Homomorphic Encryption, and Trusted Execution Environments, it offers nilDB for encrypted distributed storage, nilCC for private compute in TEEs, and nilAI for confidential LLM inference — targeting AI, DeFi, and identity applications where data privacy is critical.
