LimeChain
LimeChain is a blockchain development and consulting company that provides end-to-end services for startups and enterprises seeking to build on Web3 technologies. LimeChain offers deep expertise across a wide range of protocols, delivering solutions that include custom dApp development, DeFi product engineering, smart contract creation and audits, and strategic blockchain consulting. It works with clients to navigate the complexities of the decentralized web, from initial proof-of-concept and architecture design to full-scale implementation and support.
The company has established itself as a key development partner within numerous blockchain ecosystems, including a significant and long-standing relationship with Hedera. LimeChain has been instrumental in building core functionalities and tools for the Hedera network. Their collaborative work includes leading the development of the Hedera Token Service (HTS) and creating an open-source demonstration of the Hedera Consensus Service (HCS) integrating with enterprise systems such as Microsoft Dynamics.
Furthermore, LimeChain was a key technical partner in developing Hashport, a pioneering interoperability solution that uses HCS to bridge assets between Hedera and other major networks.

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.
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.

Taskbar is a decentralized freelance marketplace and gig-economy platform built on the Hedera blockchain network. It connects clients with freelancers for on-demand tasks and services in a more efficient, transparent, and equitable Web3 environment. It acts as an alternative to traditional freelance websites by addressing issues such as high commission fees and slow payment settlements.
Taskbar facilitates payments in HBAR, USDC, and other Hedera-based tokens, enabling near-instant settlement directly to a freelancer's wallet. A key feature is its on-chain escrow system, where funds for a job are locked in a smart contract and released automatically upon successful completion of the task, ensuring security for both parties. It also boasts a gamified reputation system implemented to build trust and incentivize positive user behavior.
To enhance transparency and trust, Taskbar utilizes the Hedera Consensus Service (HCS) to create an immutable and auditable log of all critical platform activities, including task creation, proposals, and reviews. This forms the basis of a verifiable on-chain reputation system for freelancers.
