The Hyperledger Fabric plugin for Hedera Consensus Service (HCS) enables Hyperledger Fabric networks to utilize the Hedera public network for transaction ordering. This plugin allows developers to replace or augment traditional Fabric ordering services such as Raft or Kafka with HCS, leveraging Hedera's asynchronous Byzantine Fault Tolerant (aBFT) consensus mechanism.
The core function of the plugin is to have Fabric orderer nodes submit endorsed transactions to a designated topic on the Hedera Consensus Service. HCS then assigns these transactions a unique, immutable, and verifiable consensus timestamp and sequence. Fabric orderers subscribe to this topic via a Hedera mirror node, retrieve the ordered transactions, and use this sequence to consistently form blocks and propagate them within the private Fabric network.
By integrating HCS, Hyperledger Fabric applications gain several benefits including enhanced trust and decentralization in the ordering process, public verifiability of transaction sequences for increased auditability, and potentially reduced operational complexity compared to managing a traditional private ordering service.

Pyth Network is a first-party financial oracle network that supplies extremely low-latency real-world price data across crypto, equities, forex, commodities, and ETFs. In February 2024 the Pyth catalog of over 400 price feeds was launched on Hedera via a partnership with the HBAR Foundation, giving developers permission-less access to real-time data and confidence intervals to improve DeFi risk management. HLiquity, a decentralized borrowing protocol on Hedera, became the first application to integrate these feeds to ensure accurate pricing and proper collateralization.
MetaStable is a decentralized finance (DeFi) platform that aims to provide a secure, private, and compliant environment for trading synthetic assets. The company is focused on leveraging advanced cryptographic techniques to solve some of the key challenges in the DeFi space, such as high slippage, impermanent loss, and regulatory uncertainty.
The core of MetaStable's service is its Automated Market Maker (AMM), which is designed to facilitate the trading of synthetic assets with minimal price impact. A key feature of the platform is its use of Zero-Knowledge Proofs (ZKPs), which allows for the verification of transactions without revealing the underlying data. This provides a high degree of privacy and confidentiality for users. The platform also includes a "DeFi Firewall," a proprietary technology that helps to ensure regulatory compliance by preventing illicit funds from entering the ecosystem.
MetaStable’s "chain-agnostic" design and support for EVM-compatible DLTs allows it be interoperable with various networks including the Hedera blockchain.
The Liechtenstein Protocol is a decentralized compliance protocol developed by LCX, a regulated fintech company based in Liechtenstein. It’s designed to standardize the way security tokens and other tokenized assets are issued and traded on blockchains, with a strong focus on regulatory compliance.
The core of the Liechtenstein Protocol is a set of on-chain and on-token-level rules that can be embedded directly into a digital asset. These rules can automate compliance with a wide range of legal and regulatory requirements, such as those related to KYC (Know Your Customer) and AML (Anti-Money Laundering). Key services enabled by the protocol include on-chain asset management, which allows for the issuance, timelocking, and burning of tokens, as well as real-time tracking of a token's ownership through a "Token Holder Registry."
The Liechtenstein Protocol is blockchain-agnostic, but it has a key integration with the Hedera network leveraging the Hedera Token Service (HTS) to provide a secure, transparent, and compliant infrastructure for digital securities.
NFT.com is a platform dedicated to the world of non-fungible tokens (NFTs), providing a comprehensive ecosystem for creators, collectors, and brands. The company, which is a subsidiary of Immutable Holdings, aims to be a central hub for the NFT community, offering a range of services designed to enhance the user experience and drive the adoption of digital collectibles.
The core of NFT.com's service is its marketplace and social platform. It allows users to create personalized NFT galleries to showcase their collections, which in turn form the foundation of a decentralized Web3 social network. The platform provides tools for minting new NFTs, as well as for buying, selling, and trading them. A key feature is the "Genesis Key," an NFT that provides holders with a lifetime, fee-free membership to the platform and the ability to create a custom profile.
NFT.com is built on Hedera with multi-chain functionality baked in. By building on Hedera, NFT.com can leverage the network's high throughput, low fees, and carbon-negative infrastructure to provide a fast, efficient, and sustainable experience for its users.
