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.
Phala Network is a hardware-secured compute platform for verifiable AI and confidential applications using Trusted Execution Environments. It provides GPU TEE support on NVIDIA H100, H200, and B200 chips alongside Intel and AMD CPU TEEs, enabling developers to deploy confidential AI models, containerized workloads via the dStack SDK, and confidential virtual machines with real-time cryptographic attestations. Phala targets privacy-preserving AI inference, enterprise data processing, and decentralized compute where verifiable execution and data confidentiality are required.
Secret Network is a layer-1 blockchain with privacy-preserving smart contracts, using trusted execution environments (TEEs) to enable encrypted inputs, outputs, and state for decentralized applications. Built on the Cosmos SDK, it supports confidential DeFi, private NFTs, access-controlled data, and cross-chain privacy via IBC and bridges to Ethereum and other networks. Recent additions include SecretVM on AMD SEV-SNP hardware and Secret AI, a confidential compute layer for GPU-based large language model workloads running inside verifiable TEEs.
