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.

OneSpan is a Web3 platform that offers a dedicated eClosing solution designed to digitize and secure the entire lifecycle of high-value digital agreements, particularly in the mortgage and lending industries. The platform streamlines the closing process by enabling remote online notarization (RON), electronic signatures, and identity verification, all within a secure and compliant digital environment. A central component of this solution is the OneSpan eVault, a specialized repository for managing the authoritative copy of critical digital documents, such as promissory notes (eNotes).
To provide an unparalleled level of trust and auditability, OneSpan has integrated its platform with ProvenDB, a data integrity service built on the Hedera network. When a document is signed or a key milestone is reached in the eClosing process, a cryptographic fingerprint (hash) of the agreement is anchored to the Hedera public ledger. This action, facilitated by ProvenDB, creates a permanent and immutable timestamped record on the Hedera Consensus Service (HCS).
Banxa is a global financial technology company specializing in payment processing. Its services provide interconnectivity between the traditional financial (TradFi) system and the digital asset economy. It currently processes more than $10 billion in payments annually for a wide range of clients including Visa, MasterCard, Kraken, and dozens more.
The company’s core service suite offers solutions for the facilitation of fiat-to-crypto and crypto-to-fiat conversions allowing businesses to accept and process cryptocurrency payments while enabling users to purchase digital assets. This allows for the seamless integration of cryptocurrency payments, trading, and compliance solutions enabling one-stop global expansion into more than 150 countries serviced and unlocking new revenue streams for businesses.
Banxa also provides robust compliance tools, including know your customer (KYC) and anti money-laundering (AML) solutions with more than 45 licenses. It also offers trading and wallet infrastructure through APIs and SDKs, enabling businesses to integrate cryptocurrency buying, selling, and holding functionalities directly into their own platforms via the Hedera blockchain.
Tolam Earth is a Web3 marketplace and data utility platform engineered to enhance the efficiency, transparency, and credibility of the Voluntary Carbon Market (VCM). Launched as a joint venture with backing from the HBAR Foundation, Tata Consultancy Services (TCS), and Object Computing, Tolam directly addresses critical market challenges such as price opacity, illiquidity, and concerns over the integrity of carbon credits.
Built on the Hedera network, the platform provides a marketplace for corporate buyers and carbon project developers to transact in Digital Environmental Assets (DEAs). It leverages the Hedera Token Service (HTS) to represent carbon credits as unique tokens and the Hedera Consensus Service (HCS) to create a publicly verifiable and immutable audit trail for all transactions and credit retirements. This ensures a high degree of trust and transparency for all participants.
A core component of the platform is its "mitigation engine," which employs sophisticated matching algorithms. This engine helps corporate buyers discover and purchase carbon offsets that align precisely with their specific Environmental, Social, and Governance (ESG) goals, considering factors like project type, geographical location, and additional community or biodiversity co-benefits.
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.
