B4E
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.

Slime World is a play-to-earn (P2E) mobile game developed by NADA Digital. It’s the flagship title published under Hedera Guild Games and is available on Android and iOS. The game leverages the Hedera blockchain platform's speed, low transaction fees, and carbon-negative footprint to offer an engaging blockchain gaming experience where players collect and nurture pets called "Slimes" to protect their world and defend against the encroaching "Dark Slimes."
Players complete quests and embark on adventures to earn in-game currency called "Orichalcon" through various activities. The Orichalon can be exchanged for the Hedera Guild Games (HGG) token (formerly NADA Protocol token) a utility token based on the Hedera blockchain. It can be used within the game for upgrading player’s Slimes, purchasing items to aid in adventures, and creating unique Slime NFTs that can be collected and traded via an in-game marketplace.
Gameplay centers around a strategic tower defense-style "infinite mode" where players take on waves of enemies and a "PVP arena mode" wherein players battle one another using their owned or rented Slime NFTs.
Slime World also features mini-games such as "Super Jump" and "Road Crossing," a roulette system for rewards, enhanced social features including user profiles and global chat, and a built-in multi-staking service for HGG tokens.

The Hedera Wallet Snap is a powerful open-source plugin that extends the functionality of MetaMask, one of the world's most popular crypto wallets, to the Hedera network. Developed by Tuum Technologies and managed by Hashgraph, the Snap allows users and developers to interact directly with Hedera's native services without relying on a JSON-RPC relay.
At its core, the Hedera Wallet Snap transforms MetaMask into a native Hedera wallet. This provides users with a familiar interface to manage their HBAR and other Hedera-based assets. Key services include the ability to send and receive HBAR, view account information and token balances, and interact with the Hedera Token Service (HTS), Hedera Consensus Service (HCS), and Hedera Smart Contract Service (HSCS). This comprehensive functionality empowers developers to build and deploy sophisticated decentralized applications on Hedera, while providing a seamless and intuitive experience for end-users.
The integration of the Hedera Wallet Snap opens up the network to MetaMask's vast user base of over 30 million monthly active users, greatly expanding the potential reach of Hedera-based applications.
Flowcarbon is a climate technology company focused on the Voluntary Carbon Market (VCM). Its mission is to make carbon markets more transparent, liquid, and accessible, through the use of blockchain technologies, thereby accelerating the flow of capital directly to projects that reduce or remove carbon emissions from the atmosphere. The company addresses critical inefficiencies in the traditional carbon market, such as opaque pricing, high transaction costs, and limited access for smaller participants.
The core of Flowcarbon's model is the tokenization of high-quality, verified carbon credits. Each token represents a real-world, certified tonne of carbon offset. This process creates a transparent and immutable record of ownership and transactions, enabling credits to be traded efficiently on digital marketplaces. One of the company’s initial token concepts was the Goddess Nature Token (GNT), designed as a liquid asset backed by a bundle of nature-based carbon credits.
By creating a more functional and efficient market infrastructure, Flowcarbon aims to provide project developers with faster access to financing and better price discovery. For buyers, from large corporations to individuals, it offers a more direct and transparent way to purchase credits and offset their carbon footprint.

Tejouri is a highly secure digital vault platform designed for the storage and management of sensitive personal and corporate documents. Launched by Moro Hub, a subsidiary of Digital DEWA (Dubai Electricity and Water Authority), Tejouri provides a trusted environment for users to safeguard their most vital information, including passports, financial records, contracts, and health data. The platform combines secure, UAE-based data centers with the transparent trust layer of a public distributed ledger.
The core of Tejouri’s advanced security model is its integration with the Hedera blockchain network. While the actual documents are stored securely off-chain, every critical action performed within the vault, such as uploading a file, sharing a document, or executing a digital signature, is recorded on the Hedera Consensus Service (HCS). This process creates an immutable and publicly verifiable audit trail. A cryptographic fingerprint (hash) of the event is logged on the Hedera ledger, providing a permanent, tamper-proof timestamp and record of the transaction.
