W3C DIDs
W3C Decentralised Identifiers (DIDs) are a new type of globally unique identifier designed to enable verifiable, decentralised digital identity. As a formal web standard published by the World Wide Web Consortium (W3C), the DID architecture is a foundational component for building a more secure and user-centric internet.
Unlike traditional identifiers such as email addresses or usernames, DIDs are not tied to any centralised registry or company. This means that individuals and organisations can create and control their own identifiers, giving them "self-sovereign" control over their digital identities. The core of the system is the DID Document, a JSON file that contains the cryptographic keys and service endpoints associated with a DID. This document is stored on a distributed ledger or other decentralised network, allowing for secure and verifiable interactions.
The Hedera Consensus Service (HCS) is used to create a tamper-proof and auditable log of all DID-related events, such as creation, updates, and revocation.

Certara is a global leader in biosimulation, a technology that uses computer models to predict how drugs will behave in the human body. Founded in 2008 and headquartered in Princeton, New Jersey, its mission is to accelerate the development of new medicines by transforming the traditional drug discovery and development process.
The company offers a comprehensive suite of software and services that are used by over 2,000 biopharmaceutical companies, academic institutions, and regulatory agencies in 62 countries. Certara's Simcyp Simulator, for example, is a physiologically-based pharmacokinetic (PBPK) modeling platform that is widely used to predict drug interactions. In addition to its software, Certara provides a range of consulting services, including regulatory science, market access, and medical writing.
Certara's OpenPharma innovation has developed a decentralized application called Hasharc that is built on the Hedera network and designed to address key challenges in the life sciences industry, such as supply chain security, patient safety, and regulatory compliance.

eMission is a Canadian company that is developing a comprehensive platform for the measurement, reporting, and verification (MRV) of enterprise carbon emissions and removal. Its goal is to provide a fully auditable and transparent system that can help businesses and governments accurately track their carbon footprint and achieve their sustainability goals.
The core of eMission's service is a platform that uses a combination of satellite data, IoT sensors, and advanced analytics to provide a detailed and near real-time view of carbon emissions. This data-driven approach is designed to overcome the limitations of traditional, often manual, methods of carbon accounting. By providing a more accurate and transparent system, eMission aims to build trust in the carbon credit market and facilitate the flow of capital to high-impact environmental projects.
eMission received a grant from the Hedera Foundation to develop a suite of open-source tools and methodologies on Hedera Guardian, a platform for creating and managing digital environmental assets. This integration will allow for the tokenisation of verified carbon credits, creating a secure and transparent market for these assets.

Joget is an open-source no-code/low-code application development platform designed to empower users, from citizen developers to professional programmers, to build, integrate, and orchestrate enterprise-grade applications and automate workflows with minimal coding. The platform focuses on accelerating digital transformation by simplifying application development and enabling faster delivery of solutions across various industries.
A key aspect of Joget's offering is its specific support for blockchain and digital ledger technology (DLT) applications through its integration with the Hedera blockchain network. This is facilitated by the Hashgraph Application Studio, a version of Joget tailored for the Hedera ecosystem, and the Hedera Ledger Pack plugin. These tools enable users to visually design and deploy decentralized applications (dApps) on Hedera, simplifying interactions with Hedera services like the Hedera Consensus Service (HCS) and Hedera Token Service (HTS) for tasks such as account creation, asset transfer, and token management, directly from within the Joget environment.
Beyond its blockchain capabilities, Joget provides visual drag-and-drop interfaces for UI and process design, AI-powered development features, pre-built integrations, and an extensible plugin architecture. This allows organizations to improve time-to-market, achieve cost efficiencies, and enhance operational flexibility for a wide range of enterprise applications.

ConsentCheq, a service by PrivacyCheq, is a consent management platform that helps businesses comply with global privacy regulations such as GDPR, CCPA, and COPPA. Since its launch in 2016, the company has focused on providing a "single source of truth" for user consent, enabling enterprises to manage and honor user privacy preferences in real-time across all their systems.
The core of ConsentCheq's service is a full-stack transparency and consent management solution. It provides tools for businesses to deliver clear privacy notices and to capture, log, and manage user consent for data collection and processing. A key feature is the "Consent Dashboard," a centralised interface where users can view and control their privacy settings for any business that uses the ConsentCheq service. The platform also offers "Consentive," an incentive-based system where consumers can be rewarded with micropayments for granting consent, which is designed to increase opt-in rates for data processing.
ConsentCheq's connection to the Hedera network is central to its "Consentive" service. The platform uses the Hedera Consensus Service (HCS) to create a high-throughput, low-cost, and auditable log of consent verification and payment events. Under privacy laws, advertising networks must verify consumer consent each time they process or track them.
