Datahash, formerly known as Entrust, is Australia's pioneering full-service agricultural supply chain platform. Focused on combating the estimated $3 billion annual global wine fraud, Datahash leverages distributed ledger technology (DLT) to ensure the authenticity and traceability of agricultural products from origin to consumer.
Datahash utilizes the Hedera Consensus Service to log supply chain events immutably. Each update is recorded to a defined topic on Hedera, requiring a signature and receiving a consensus timestamp. This approach provides a complete and verifiable history of the supply chain, enhancing transparency and trust among stakeholders.

Identity Snap, developed by Tuum Technologies, is an open-source plugin that extends the functionality of MetaMask to include support for decentralized identifiers (DIDs) and verifiable credentials (VCs). This transforms MetaMask into a DID wallet, allowing users to manage their digital identities in a secure and self-sovereign manner.
The core of the Identity Snap service is its ability to create, manage, and verify DIDs and VCs directly within the MetaMask interface. It supports multiple DID methods, including did:pkh, did:key, and did:hedera, giving users a range of options for creating and controlling their digital identities. Key features include the ability to resolve DIDs to their corresponding DID documents, create and save VCs, and generate verifiable presentations (VPs) for sharing with other parties.
Identity Snap's did:hedera method allows users to anchor their digital identities on the Hedera public ledger, taking advantage of its high throughput, low fees, and robust security. The Hedera Consensus Service (HCS) is used to create a transparent and auditable record of all DID and VC events, ensuring the integrity and verifiability of the credentials.
Demia is a climate infrastructure company that provides a sophisticated technology platform for securing and verifying data in environmental markets, particularly the carbon market. The company’s mission is to increase trust, reduce friction, and unlock value by creating a transparent and auditable foundation for climate data.
The platform is centered around a "Zero-Trust Data Fabric," which ensures that environmental data—whether from on-site IoT sensors or manual inputs—is protected and verifiable from its source. This system creates a secure chain of custody for information, streamlining the complex processes of measurement, reporting, and verification (dMRV).
As a key partner in the Hedera ecosystem, Demia leverages the Hedera Guardian, an open-source framework for auditable ESG assets. This integration allows Demia to anchor its verified data to the Hedera public ledger, creating an immutable record of a project's environmental impact. This is crucial for their clients—including carbon project developers, auditors, and corporate purchasers—who require undeniable proof of climate action to meet regulatory requirements and investor expectations.
