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.

Binance.US is a cryptocurrency exchange launched in 2019 to serve customers in the United States, operating as a separate entity from the global Binance platform. Headquartered in Palo Alto, California, it provides a regulated and compliant platform for Americans to buy, sell, and trade a wide variety of digital assets.
The exchange offers a robust suite of products and services for both beginner and experienced traders. Users have access to a selection of over 160 cryptocurrencies, which can be traded with low fees. The platform includes advanced trading features like real-time order books, charting tools, and various order types. In addition to spot trading, Binance.US also offers cryptocurrency staking for a range of proof-of-stake (PoS) assets, allowing users to earn rewards on their holdings. The service is accessible through its website and mobile apps, which are designed to provide a secure and user-friendly experience.
Binance.US is directly connected to the Hedera ecosystem as it lists Hedera's native cryptocurrency, HBAR, for trading. This allows U.S. customers to buy, sell, and hold HBAR, providing essential liquidity and accessibility for the token within the American market.
Transak is a global Web3 payment provider that builds developer-focused tools to bridge traditional finance with digital assets. The company’s core service is to enable users to seamlessly buy and sell cryptocurrencies directly within any decentralized application (dApp). This is primarily achieved through a simple, embeddable widget or API that developers can integrate into their platforms with just a few lines of code.
By handling the complex backend processes of payment processing, fraud monitoring, and regulatory compliance like KYC/AML, Transak solves a critical onboarding challenge for the Web3 ecosystem. It eliminates the need for users to leave a dApp, register on a centralized exchange, and manually transfer funds, which significantly reduces friction and improves user conversion rates. The platform supports a wide array of local payment methods across more than 150 countries, including credit/debit cards, bank transfers, and other regional options.
Transak is integrated with the Hedera network. This enables developers building on Hedera to provide their users with a direct and localized on-ramp to purchase HBAR and other Hedera-based tokens.
Numbers Protocol is a decentralized network designed to establish trust and authenticity in digital media. Its primary mission is to address the challenges of misinformation and copyright infringement by creating a verifiable record of content provenance from creation to publication. It provides a transparent and immutable history for digital assets, including images, videos, and audio files.
At its core, Numbers Protocol offers a suite of tools and services for creators and developers. This includes the "Capture App," which allows users to register their digital creations, embedding them with unique identifiers and contextual metadata. The "Numbers Blockchain" serves as a specialized distributed ledger for indexing these assets and their histories. The protocol also features a "Verify Engine," a reverse-image search tool enhanced with AI, enabling users to trace the origin and modification history of digital media.
By leveraging blockchain technology and decentralized storage, including the Hedera blockchain network, Numbers Protocol enables users to create on-chain proof of their digital media, secure ownership, and track usage.
Starling Lab for Data Integrity is an academic research center that operates at the intersection of cryptography, decentralized web protocols, and the humanities. A joint initiative between the USC Shoah Foundation and Stanford University's Department of Electrical Engineering, the lab's mission is to develop and prototype tools and principles to establish trust in digital records. In an era of rampant misinformation and AI-generated content, Starling Lab is pioneering new methods to securely capture, store, and verify digital media.
The core of their work is the Starling Framework for Data Integrity, a comprehensive, open-source methodology for authenticating digital content. This framework is built on three pillars: Capture, which involves creating a chain of custody from the moment a photo or video is taken, Store, which uses decentralized networks like IPFS and Filecoin to securely distribute and preserve content, and Verify, which leverages immutable ledgers to register and audit the provenance of digital assets. This end-to-end approach has been applied in various real-world scenarios, from documenting the 78 days of the 2020 U.S. presidential transition with Reuters to preserving the USC Shoah Foundation's archive of 55,000 holocaust testimonies.
