Aleph Zero
Privacy-enhancing public blockchain with instant finality. Aleph Zero is built for enterprise, Web 3.0, and DeFi use-cases. Aleph Zero is a proof-of-stake public blockchain. We combined an original, aBFT consensus protocol with a customized substrate stack. Currently, we’re working on enhancing the platform with a privacy framework based on Zero-knowledge Proofs (ZKPs) and secure Multi-Party Computation (sMPC) to empower developers with a unique approach to private smart contracts. During a laboratory test, Aleph Zero’s peer-reviewed consensus protocol (AlephBFT) achieved 89,600 tx/s with a 416 ms confirmation time in a decentralized test setting of 112 AWS nodes spread across five continents. Aleph Zero’s real-world performance, especially under heavy l network load, is yet to be determined. The Aleph Zero Consensus Protocol has been officially peer-reviewed and accepted for publication in the conference proceedings of advances in financial technology 2019.

Gaya Blockchain
GAYA Blockchain is the UAE’s first Layer-1 blockchain, aiming to unify gaming, social, DeFi, NFT, and real-world asset ecosystems on a single, eco-conscious platform. It uses a Proof-of-Stake consensus mechanism and is EVM-compatible, enabling developers to deploy smart contracts and leverage familiar tooling. Its architecture includes a “Cell-As-A-Service (CAAS)” data structure for efficient serialization and propagation. The Gaya Wallet serves as a multichain, non-custodial gateway to the ecosystem, offering fiat on/off ramps, in-app swaps, staking, and a gamified XP system that rewards engagement and may boost airdrop eligibility. GAYA token (GAYA) is the native utility token; it will be used for transaction fees, staking, governance through a DAO, ecosystem incentives, and in-app transactions. The economic model includes a dynamic gas mechanism with partial fee burns to introduce deflationary pressure, and carefully structured tokenomics with vesting schedules.

Nxt
Nxt is an open source blockchain platform and the first to rely entirely on a proof-of-stake consensus protocol. Launched in November 2013 and written from scratch in Java, Nxt is proof that blockchain technology is not only about simple transfer of value but also has the potential to revolutionize many aspects of our lives with the various decentralized applications that can be built with it. Today, Nxt remains one of the most tested and reliable platforms in the industry, influencing numerous other projects. With its many easy to use modular built-in features, Nxt covers most of the dApp use cases and at the same time is perfectly suitable for private blockchain implementations. Nxt was the first to implement a pure proof-of-stake consensus protocol.

XinFin
eXchange inFinite (XinFin), is a Delegated Proof of Stake Consensus network (XDPoS), enabling hybrid relay bridges, instant block finality and interoperability with ISO20022 messaging standards, making XinFin's hybrid architecture developer-friendly. Interoperable blockchain network for global trade & finance which enables digitization, tokenization, and instant settlement of trade transactions, increases efficiency, and reduces reliance on complex FX infrastructures, allowing for increased flexibility in liquidity management for financial institutions. Delegated Proof of Stake (XDPoS) leverages the power of stakeholder approval voting to resolve consensus issues in a fair and democratic way. Higher interoperability with legacy systems and other blockchain platforms makes XinFin Protocol (XDC) the language of core banking systems, ERP systems and SWIFT systems, and many more.
