HashLog
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.

The Coupon Bureau is a non-profit, industry-managed organization established to modernize the coupon industry by creating a centralized data exchange for all stakeholders. The organization's primary mission is to combat coupon fraud, an issue estimated to cost the industry hundreds of millions of dollars annually, while also improving efficiency and the consumer experience.
At the heart of The Coupon Bureau's work is the development and implementation of the new Universal Coupon standard, also known as AI (8112). This new standard replaces the outdated barcode system with a more secure, serialized format for both digital and paper coupons. This allows for real-time validation of every coupon at the point of sale, effectively eliminating counterfeiting and ensuring that each coupon is used only once, as intended by the manufacturer. The platform, known as the Universal Positive Offer File, serves as this central repository for all coupon data, connecting manufacturers, retailers, and consumers in a seamless ecosystem.
The Coupon Bureau utilizes the Hedera Consensus Service (HCS) to create a tamper-proof, auditable log of every coupon's lifecycle. Each time a coupon is created, distributed, or redeemed, a transaction is recorded on the Hedera public ledger.

HashPack is a leading non-custodial wallet specifically designed for the Hedera Hashgraph network. It provides integrated interaction with the HBAR and Hedera Token Service (HTS) tokens, as well as with non-fungible tokens (NFTs) and decentralized applications (DApps) within the Hedera ecosystem.

HashPack facilitates interaction within the Hedera ecosystem through its DApp browser, connecting users to DeFi protocols, NFT marketplaces, and other decentralized applications and supports in-wallet swaps via integrations with decentralized exchanges on Hedera, such as SaucerSwap.

Meta Carbon is a climate-tech company founded dedicated to making carbon offsetting more transparent, efficient, and engaging. Its mission is to simplify carbon management for businesses and individuals, using technology to bridge the gap between climate action and everyday life.
The core of Meta Carbon's service is its software-as-a-service (SaaS) platform, which provides a comprehensive suite of tools for carbon project management. These include features for inventory management, real-time reporting, and yield optimization. The platform also offers a range of engagement tools, such as offset certificates, digital badges, and leaderboards, which allow businesses to transparently showcase their sustainability efforts to their customers. A key feature of the platform is its ability to integrate with e-commerce sites, enabling carbon offsetting at the point of sale.
Meta Carbon uses the Hedera Consensus Service (HCS) to record every transaction, measurement, and retirement of carbon credits on the public ledger. This provides a high level of transparency and trust, as all data is immutable and auditable.
The IBM Blockchain Platform was a short-term funding and technology project involving the Hedera blockchain network. While this specific project has evolved into an ongoing enterprise blockchain strategy, IBM remains intrinsically involved with the Hedera network as a member of the Hedera Governing Council.
This position provides IBM with a direct voice and vote in the governance of the Hedera public network, influencing its technical roadmap, policies, and overall strategic direction. As a council member, IBM also contributes to the network's operational integrity by running a consensus node.
This engagement with Hedera allows IBM to participate, offer insights and contribute to advancements which align with its broader interests in advancing enterprise-grade distributed ledger solutions (DLT). This involvement complements IBM's extensive work with permissioned blockchains and strengthens the partnership between Hedera and the broader technology industry while providing a holistic perspective on the evolving blockchain landscape for IBM’s global enterprise clients.
