RISC Zero is zero-knowledge virtual machine that can run on any platform. It’s a virtual microcontroller / co-processor that produces receipts for every program it runs. These receipts can be verified at anytime by anyone in milliseconds.
Espresso is a layer 1 blockchain system that combines proof-of-stake consensus and a ZK-Rollup mechanism to achieve high throughput and low fees. Espresso has also developed Configurable Asset Privacy for Ethereum (CAPE), an application that can run on any EVM blockchain.
Ingonyama is focused on hardware acceleration for zero knowledge proof algorithms and other advanced cryptography. They are working closely with several teams building rollups to unlock the full potential of zero knowledge proofs for scaling.
Scroll is an EVM-equivalent ZK-rollup built in early 2021 as part of the vibrant Ethereum ecosystem. Scroll uses zkEVM as its core component to prove the native EVM execution trace and leverages a decentralized proving network to solve the efficiency problem on the prover side.
Nomad is a novel approach to blockchain interoperability that leverages an optimistic mechanism to increase the security of cross-chain communication. Using Nomad, developers can securely build cross-chain applications (or xApps) and bridge assets between chains.
Aurora is an Ethereum Virtual Machine with a bridge that enables the trustless transfer of ERC-20 tokens and ETH between Ethereum and Aurora. It creates interoperability between NEAR and Ethereum and was developed by team members of NEAR protocol.
Aztec is an open source layer 2 network championing scalability and privacy in the Ethereum network. Built on PLONK, a superfast SNARK technology, Aztec acts as a privacy shield for financial transactions protecting users and business identity and balance data.
Axelar stack provides a decentralized network, protocols, tools, and APIs that allow simple cross-chain communication. A decentralized open network of validators powers the network; anyone can join, use it, and participate. Byzantine consensus, cryptography, and incentive mechanisms are designed to achieve high safety and liveness requirements unique for cross-chain requests.
Osmosis is an independent blockchain network within the Cosmos ecosystem. It is an automated market maker (AMM) and decentralised exchange (DEX) built using the Cosmos SDK as a chain from the Cosmos Hub.
Penumbra is a shielded, cross-chain network allowing anyone to securely transact, stake, swap, or marketmake without broadcasting their personal information to the world. This enables private trading in any cryptoasset including fungible and non-funglible tokens.
Iron Fish is a Layer 1 blockchain that provides the strongest privacy guarantees on every single transaction. Leveraging zero-knowledge proofs (zk-SNARKs), and the highest industry standards for encryption, Iron Fish gives you complete control over who sees transaction details via account view keys or transaction decryption keys.
Anoma is a proof-of-stake blockchain protocol that enables private transactions and private bartering with any number of parties to increase the chance of finding suitable trading partners. Transaction data is kept anonymous for all traded assets which includes currency, NFTs and other goods and services.
zkSync, is a user-centric zk rollup platform developed by Matter Labs It is a scaling solution for Ethereum that is already live on the mainnet. The main feature of zkSync are extremely low transaction fees, trustless protocol, cryptographic security, full user control of funds and no requirement for operational activity to secure funds.
Aleo provides tools to build private and zero knowledge applications with ease. It is the world’s first IDE built intentionally for zero knowledge proofs. Developers create their app using Leo, a language that requires no cryptography, apps are compiled on the platform and deployed to the blockchain within a short timeframe.
rhino.fi (previously DeversiFi)
rhino.fi is a Layer 2 gateway to multi-chain DeFi facilitating fast, private and gas free transactions. You can buy, trade and invest effortlessly across all of your favourite blockchains from a single wallet. rhino.fi uses zkSTARKS – a technology that permits thousands of transactions to be settled in a single batch transaction.
Moonbeam provides smart contract functionality across different blockchains that is fully Ethereum-compatible. The cross-chain functionality, enabled through a parachain of the Polkadot network, allows DApp developers to extend their reach to new users and assets. Moonbeam is decentralized and permissionless, contains a full EVM implementation and extends Ethereum features to include on-chain governance and staking.
