Hashlog is a data verification service that leverages the Hedera Consensus Service (HCS) to create immutable events or data logs. It enables applications and enterprises to submit messages to the HCS, where each message receives a consensus timestamp from the Hedera network, ensuring its integrity and order. This process provides a secure and transparent "proof-of-action" or "proof-of-event" capability.
Its core functionality offers a data trail for on-chain information. Once data is logged via Hashlog to the HCS, it cannot be altered or retrospectively tampered with, providing a high degree of data integrity. This is particularly useful for use cases requiring regulatory compliance, dispute resolution, or the tracking of critical operational processes. Developers integrate Hashlog systems using APIs or SDKs.
By utilizing Hedera, Hashlog provides decentralized trust, cryptographic verification, and public accessibility (if desired) for the logged information. Its applications span across multiple domains, including supply chain management for tracking goods, IoT data streams for device event verification, and legal tech for timestamping documents.

DaVinciGraph is a comprehensive token management platform operating on the Hedera blockchain network. Its platform is designed to enhance the functionality and efficiency of projects within the Hedera ecosystem through a suite of service offerings for token creators and NFT projects.
Its key offerings include tools for on-chain token management, token locking and vesting, and a token burner service for managing supply called “Blackhole.” This feature allows for permanent removal of tokens from circulation, ideal for creating deflationary effects or making irreversible token commitments within the Hedera ecosystem.
DaVinciGraph also features "DaVinciPics," a service for managing and displaying token and NFT logos consistently across decentralized applications (DApps).
The DaVinciGraph platform offers a token launchpad for new projects to introduce their tokens and a novel airdrop system. It also features the DAVINCI token, which gives holders unique access to NFT and related events. Its overall goal is to support a scaling, secure, and transparent environment for comprehensive token lifecycle management and project funding.

Carbon Central, developed by Australian tech firm NoviQTech, is an enterprise-grade software platform designed to help large organizations manage the complexities of carbon accounting and environmental, social, and governance (ESG) reporting. The platform provides a unified, end-to-end solution for companies to measure, analyze, and report on their environmental footprint, particularly their Scope 1, 2, and 3 carbon emissions. It aims to replace disparate spreadsheets and manual data collection methods with a single, auditable system of record.
The platform is built on the Hedera network, leveraging its technology to bring a high level of integrity and trust to the ESG data management process. A key feature of Carbon Central is its use of the Hedera Consensus Service (HCS) to create an immutable and verifiable audit trail. As enterprises input emissions data, supplier information, and other critical ESG metrics into the platform, a cryptographic hash of that data is submitted to the Hedera public ledger. This process provides a tamper-proof timestamp and a transparent, auditable record that can be securely shared with and verified by regulators, investors, and other stakeholders.
Blockchain for Energy (B4E) is a non-profit, member-led consortium dedicated to driving digital transformation within the energy sector. Comprising major energy companies including Chevron, ExxonMobil, and Repsol, B4E was established to collaboratively develop and implement blockchain-based solutions that can enhance efficiency, reduce costs, and increase transparency across the industry.
The consortium's flagship product is the B4ECarbon platform, an advanced digital measurement, reporting, and verification (dMRV) solution. This platform integrates AI and IoT with distributed ledger technology to provide a secure and auditable system for managing emissions data. It enables energy operators to track, report, and verify their environmental performance in near real-time, helping to prevent greenwashing and ensure compliance with global standards. The B4E Network & Platform, built on Hyperledger FireFly, serves as the foundational layer connecting all of the consortium's solutions in a decentralised environment governed by its members.
The B4ECarbon platform is built on the Hedera public network, and has been a member of the Hedera Governing Council since June 2025.
