The harder to trace Stablecoin Protocol
The ZERA Protocol is a universal, direct-deposit privacy layer for the assets you already hold. It's token and chain-agnostic: bring existing tokens (e.g., USDC, USDT, SOL and more) into a single, unified cryptographic pool to receive shielded balances with private transfers—including offline, device-to-device payments that sync to chain later. No synthetic pegs, no mixers, no bridging - just a composable privacy layer designed for real usage.

ZERO is a revolutionary cryptocurrency and transaction platform based on Zcash. ZERO offers total payment confidentiality, while still maintaining a decentralised network using a public blockchain. ZERO combines Bitcoin’s security with Zcash’s anonymity and privacy. ZERO stands out from the competition as a fully working product that has already implemented a set of special features not found in any other cryptocurrency.
ZEROBASE is a high-performance, decentralized zero-knowledge (ZK) proving network built for real-time computation, regulatory compliance, and large-scale commercial use. It is designed to address the core trust gaps in global finance, where trillions of dollars move daily through systems that remain fragmented, inefficient, and opaque. ZEROBASE supports a broad range of ZK applications, including zkLogin, zkDarkPool, zkVote, and zkCEX, and offers both standard and custom circuit development. With free integration, custom circuits delivered in 2–3 weeks, and compatibility with Circom, Gnark, and an optional decryptable circuit layer, ZEROBASE supports agile development across both Web3 and enterprise sectors.

Open, free and uncensorable websites, using Bitcoin cryptography and BitTorrent network

Is fully private multi-blockchain solution. Low transaction fees, atomic swaps and common anonymity set

The Zion app is a peer-governed social network where members are the true owners of their data with BTC lightning integration.
ZisK is a high-performance zkVM (Zero-Knowledge Virtual Machine) designed to generate zero-knowledge proofs of arbitrary program execution. It enables developers to prove the correctness of a computation without revealing its internal state, making ZisK a powerful tool for privacy-preserving and verifiable computation.


ZK Email allows to verify emails according to DKIM protocol using zero-knowledge proofs.

Privacy-preserving self-custodial unforgeable proof of identity.

Pioneering Privacy AI with Decentralized Infrastructure (DePIN)
ZKCHAOS is a layer2-based anonymous transaction protocol, and a fair game platform, which is built to enhance privacy for all kinds of cryptocurrency
ZKEncrypt AI leverages Fully Homomorphic Encryption (FHE) for computations on encrypted data (Eval(f, Enc(m)) → Enc(f(m)) under Ring-Learning With Errors (RLWE) assumptions), integrated with Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge (ZK-SNARKs) for verifiable privacy. Built natively on the Solana blockchain using Rust-based smart contracts and the Anchor framework, with AI-driven optimizations via libraries like Microsoft SEAL for noise management and ciphertext packing. Special Features: Hybrid FHE-ZK Protocols: Seamless combination enabling encrypted on-chain computations with zero-knowledge attestations, reducing latency by up to 10x in high-throughput scenarios. AI-Optimized Scalability: Machine learning models dynamically adjust encryption parameters for Solana's parallel processing, supporting applications like confidential DeFi transactions or shielded NFT transfers. End-to-End Blockchain Privacy: Nodes process encrypted queries (e.g., private ML inferences) without decryption, ensuring tamper-proof integrity via Solana's consensus. Open-Source Compatibility: Modular design for easy integration with existing dApps, with prototypes demonstrating efficient handling of transaction-heavy workloads. Why Users Should Adopt ZKEncrypt AI: In a landscape of escalating data breaches and regulatory scrutiny (e.g., GDPR, MiCA), ZKEncrypt AI empowers developers and users to build trust-minimized applications on Solana, where privacy is not an afterthought but a core primitive. By enabling fully encrypted web interactions on blockchain, it mitigates intermediary risks, unlocks novel use cases like anonymous voting or secure supply-chain verification, and positions Solana as a leader in privacy-preserving DeFi. Early adopters gain a competitive edge in scalable, confidential computing without compromising performance.
