Hedera Hashgraph
Hedera is owned and governed by the world's leading organizations. Hedera is the most used enterprise-grade public network for you to make your digital world exactly as it should be – yours. HBAR is the native, energy-efficient cryptocurrency of Hedera that powers the decentralized economy. Whether you're a startup or enterprise, a creator or consumer, Hedera goes beyond blockchain for developers to create the next era of fast, fair, and secure applications. Bitcoin pioneered decentralized infrastructure and Ethereum brought programmability. But earlier proof-of-work blockchains consume massive amounts of energy and process transactions slowly in order to achieve acceptable levels of security. Heavy bandwidth consumption by these technologies leads to expensive fees, even for a simple cryptocurrency transaction. The Hedera proof-of-stake public network, powered by hashgraph consensus, achieves the highest-grade of security possible (ABFT).

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.

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.
