Iron Fish is a Layer 1 blockchain aiming to be the universal privacy layer for all of Web3. It uses zero-knowledge proofs (zk-SNARKs) and the highest industry standards for encryption, enabling users to have fully private transactions—a true SSL layer for all blockchains.In March 2025, Base acquired the Iron Fish development team to develop privacy protection primitives for Base. The specific acquisition amount was not disclosed. This acquisition is limited to the Iron Fish team and does not involve the Iron Fish network, tokens or its technology. The Iron Fish project will remain independent and is not affiliated with Coinbase or Base.

Hashflow is a decentralized exchange platform designed for interoperability, zero slippage, and MEV-protected trades. It connects institutional market makers to traders using a novel Request-for-Quote (RFQ) model.

NEAR is a sharded, proof-of-stake, layer-one blockchain that aims to incentivize a network of computers to operate a platform for developers to create and launch decentralized applications. Central to its design is the concept of sharding, a process that splits the network's infrastructure into several segments so that nodes only have to handle a fraction of the network's transactions. The NEAR mainnet went live in August 2020.

Agoric is a Layer 1 Proof-of-Stake public blockchain designed to enable developers to rapidly build secure smart contracts in the world's most popular programming language, JavaScript. Agoric can quickly bring millions of developers to the DeFi frontier. With Hardened JavaScript, Agoric provides the safe and stable environment that developers need to build, deploy, and operate sophisticated Dapps, NFTs, and DeFi markets.

Mina Protocol is a lightweight blockchain that maintains a constant size of just 22 kB, regardless of how many transactions are committed to the network. This size enables anyone to operate a node and help secure its network without needing sophisticated computer hardware. The key feature of Mina Protocol is the incorporation of zk-SNARKs, which allows users to confirm they have certain data without revealing that data to each other. The Mina mainnet was launched on March 23, 2021.

Avalanche is a platform created by Ava Labs for creating custom blockchain networks and decentralized applications (dApps). It claims great scalability, with a high transaction throughput (TPS) of 4500 transactions per second. Its novel consensus protocol, Subnet infrastructure, and HyperSDK toolkit enable Web3 developers to easily launch powerful, custom blockchain solutions.

Conflux is a high-throughput, first-layer consensus blockchain designed for dApps that require speed at scale without sacrificing decentralization. Its Tree-Graph structure can confirm multiple blocks concurrently, leading to lower confirmation times and increased transaction throughput. As a regulatory-compliant, public, and permissionless blockchain in China, Conflux is building a borderless transactional and technological ecosystem for globally-minded crypto projects, extending beyond China to North America, Russia, Latin America, Europe, Africa, and the rest of the world.

Algorand is a decentralized, scalable, and secure blockchain infrastructure. It offers transaction throughputs at the speed of traditional finance, with immediate finality, near zero transaction costs, and 24/7 availability. From decentralized finance to generative NFT art, Algorand is powering the economic models of the future. Algorand was designed by MIT professor and Turing Award-winning cryptographer Silvio Micali.

Spacemesh is an open-source, programmable cryptocurrency platform powered by a novel Proof-of-Space-Time (PoST) consensus protocol. It aims to create a global programmable infrastructure for tokenized apps, communities, and economies.

The Oasis Network is a Layer 1, proof-of-stake, decentralized network designed to support the next generation of blockchain applications. It is incredibly versatile, agile, and customizable. Moreover, it supports confidential smart contracts, enabling sensitive data to be used by Dapps and unlocking new use cases and applications of blockchain technology.

StarkNet is a permissionless, decentralized Validity-Rollup (also known as a "ZK-Rollup"). It operates as an L2 network over Ethereum, enabling any dApp to achieve unlimited scalability for its computations without compromising Ethereum's composability and security. This is possible due to StarkNet's reliance on the safest and most scalable cryptographic proof system: STARK.

Orchid is a platform that enables an onion routing network incentivized by OXT and a multi-hop VPN client. It aggregates the services of numerous high-quality VPN providers in a unique, decentralized marketplace powered by OXT tokens. Bandwidth providers register as sellers on the network by staking their own capital up-front in the form of OXT. This staked capital functions like a security deposit, incentivizing VPN bandwidth providers to supply users with high-quality service. Providers who fail to do so are risking their own capital.

Basis is a stable cryptocurrency protocol with an algorithmic central bank designed to remove volatility. It is designed to keep prices stable by algorithmically adjusting the supply, similar to how central banks buy and sell fiscal debt to stabilize purchasing power. When demand is increasing, the blockchain will create more Basis, with the expanded supply designed to bring the Basis price back down. Conversely, when demand is decreasing, the blockchain will buy back Basis, with the contracted supply designed to restore the Basis price. Following intervention by the U.S. SEC, Basis was shut down in December 2018.

Chia is a cryptocurrency and blockchain-based smart transaction platform. It was designed from the ground up to make cryptocurrency easier to use and more secure than cash. Chia's blockchain maintains the same level of security as Bitcoin's, while using a fraction of the energy. The Chia mainnet was launched on March 19, 2021.

Kadena is a Layer 1 Proof-of-Work blockchain that aims to optimize for scalability. It features a new smart contract language, dubbed Pact, which comes equipped with formal verification and upgradeable smart contracts. Furthermore, Kadena uses a new Proof-of-Work consensus mechanism called Chainweb, consisting of multiple individually mined chains which work in parallel to execute network transactions.
