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.

Chainlink is a decentralized oracle network connecting smart contracts on various blockchains with real-world data, events, and off-chain computation. Its fundamental purpose is to enable hybrid smart contracts by providing them with secure and reliable access to external resources, thereby bridging the gap between on-chain and off-chain environments. Chainlink is recognized as an industry standard for building, accessing, and selling oracle services.
The platform offers a comprehensive suite of services to developers and enterprises. These include “Chainlink Price Feeds,” which deliver accurate and tamper-proof financial market data to DeFi applications, “Chainlink VRF” (verifiable random function) for generating provably fair randomness essential for NFTs and blockchain gaming, and “Chainlink Automation,” which provides decentralized and reliable smart contract automation. Furthermore, “Chainlink Functions” allow smart contracts to connect to any external API and run custom computations, while the cross-chain interoperability protocol (CCIP) facilitates secure data and token transfers across different blockchain networks. Chainlink Proof of Reserve offers automated verification of on-chain and off-chain reserves.
The InterWork Alliance (IWA) is an organization focused on simplifying and standardizing the use of token-powered services for businesses. As an initiative of the Global Blockchain Business Council (GBBC), the IWA works to create a common language and framework for tokenized assets, which allows different blockchain networks and applications to work together seamlessly.
The alliance's primary mission is to empower organizations to adopt and use token-based distributed services in their day-to-day operations. To achieve this, the IWA has developed several key frameworks, including the Token Taxonomy Framework (TTF), which provides a common set of definitions and standards for tokens of all types. The IWA also has a strong focus on sustainability, with task forces dedicated to creating standards for Voluntary Ecological Markets and Carbon Emission Tokens.
The Hedera network and its ecosystem partners are active members and contributors to the InterWork Alliance. Hedera has collaborated with the IWA on its Sustainability Working Group, and several applications built on Hedera are designed to be compliant with the IWA's standards.
METAVRSE is a technology company advancing e-commerce through its proprietary, web-based 3D development engine. The platform enables brands to create, manage, and scale immersive virtual worlds and interactive product showcases accessible across all devices without requiring special downloads. This focus on accessibility and high-fidelity graphics positions METAVRSE as a key provider of infrastructure for the next generation of Web3 commerce.
The company's flagship product, TheMall, is a photorealistic virtual shopping center that utilizes the Hedera Token Service (HTS) for minting assets. Within its virtual spaces, brands can build 3D storefronts stocked with digital products and services secured on the Hedera blockchain network. For example, virtual real estate, such as floors and parcels within TheMall, is delivered and owned as NFTs on the Hedera network.
METAVRSE aims to simplify 3D spatial space design and development in the same way Canva made digital art and graphic design accessible for creative users. It has a slate of Fortune 500 clients including Microsoft, MasterCard, JP Morgan and numerous others.
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.
