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.

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.
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.
