ZERT is a cryptocurrency Decentralized Finance (DeFi) system engineered on the principle of trustlessness, aiming to provide a secure environment where users maintain full, autonomous control over their digital assets. The platform distinguishes itself by not requiring users to rely on a third-party intermediary, aligning with the core ethos of decentralized technology. By integrating advanced security protocols and a unified solution architecture, ZERT strives to guarantee the perpetual safety and sovereignty of its users' cryptocurrency holdings. This focus on non-custodial control is central to the platform’s value proposition, ensuring that users have exclusive access to and management of their funds at all times. ZERT's system is therefore positioned to offer a single, reliable point of access for all necessary DeFi functions while rigorously maintaining user security and independence.

The project is operated by iCandy Interactive, a Southeast Asian game studio, and has received support from Animoca Brands, Spartan, and Wemix. ZKcandy operates a mainnet with a native KRO token and maintains a token swap interface.

zkCloud is a cloud-based zero-knowledge proof generation service that allows developers and researchers to create ZK proofs without local hardware setup. The platform supports three proving protocols, Groth16, PLONK, and ZK-STARKs, enabling users to select the approach that best fits their proof size, speed, and trusted-setup requirements. Payments are accepted via Ethereum, zkSync, and the Lightning Network, and the service exposes an API secured by token authentication for programmatic integration. The platform targets blockchain developers and ZK newcomers alike, offering a circom-language playground, tutorials, and high-performance cloud servers described as roughly three times faster than consumer laptops. zkCloud is associated with the Intmax/InternetMaximalism project ecosystem, with a roadmap that includes ZK-Rollup infrastructure.

zkFold SA is a blockchain and cryptography consulting firm providing services in zero-knowledge proof systems, smart contract development, and cryptographic protocol design, with primary focus on the Cardano ecosystem. The firm delivers full-stack project services including ZK circuit design, cross-chain bridge architecture, privacy protocols, and Layer 2 scaling solutions. Current development includes a zero-knowledge rollup implementation for Cardano. The firm's technical foundation includes zkFold Symbolic, a Haskell-based library for constructing zero-knowledge circuits. Service offerings encompass consulting for DeFi protocols, cross-chain infrastructure projects, and grant-funded initiatives, including grant proposal co-authorship and milestone-based engineering delivery. The firm was founded by Vladimir Sinyakov, who holds a Ph.D. in mathematics.

ZND is a digital asset platform offering earn, trade, and borrow services through a unified interface. The platform enables users to subscribe to yield plans across multiple cryptocurrencies and stablecoins, execute trades in digital assets alongside traditional financial instruments including equities, exchange-traded funds, and commodities, and obtain credit facilities secured by cryptocurrency holdings without traditional credit assessment requirements. The system incorporates an artificial intelligence component designed to analyze portfolio composition and provide guidance. The architecture includes a planned native token mechanism intended to provide enhanced rewards, staking functionality, and trading incentives. The platform operates under regulatory licensing for its offered services.

Zogi Labs is a game development studio that creates blockchain-based games. Its primary title, Legends of Bezogia, is a cross-platform MMORPG that operates on blockchain infrastructure. The game incorporates NFT-based avatars called Bezogis, on-chain asset ownership mechanisms, and staking functionality.

Zone21.com is a comparison and risk-assessment platform for Bitcoin-backed lending providers. The platform assigns numerical risk scores to centralized finance (CeFi) and decentralized finance (DeFi) lending platforms, with scores ranging from 29 (low risk) to 90 (critical risk). Risk assessments are based on custody models, rehypothecation practices, loan-to-value (LTV) ratios, and know-your-customer (KYC) requirements. The platform covers multiple lending providers and presents comparative data including interest rate ranges, liquidation thresholds, and accepted collateral types in structured tables. Users can customize comparisons between providers. The platform generates and publishes provider rankings.

Nockchain is a Layer 1 proof-of-work blockchain that integrates zero-knowledge proofs into its mining mechanism, referred to as zkPoW. The protocol combines traditional proof-of-work consensus with zero-knowledge verification. The computational foundation is built on Nock, a minimalist combinator calculus. The network launched without a pre-mine allocation. Developer tooling has been released, including NockApp and the Jock programming language to support application development. Zorp operates as a separate entity that holds the native NOCK asset, while the Nockchain protocol functions as an independent network.
