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.

Fresh Supply Co (FSCO) is an agri-fintech company based in Queensland Australia. It functions on the Hedera blockchain, leveraging Hedera Hashgraph to enhance transparency, traceability, and financing within agricultural supply chains. The company focuses on providing verifiable provenance for agricultural products and digitizing trade finance. By integrating with Hedera, Fresh Supply Co offers immutable record-keeping for supply chain events, which supports the verification of Environmental, Social, and Governance (ESG) credentials for agricultural producers.
Their core offering includes the "Continuity API," which facilitates the flow of payments and data through complex supply chains. This technology enables agricultural exporters to track their produce from farm to consumer utilizing global payment networks such as Mastercard. Fresh Supply Co's platform allows for the tokenization of agricultural assets, turning verifiable supply chain data into a digital asset that can be used to secure financing. This approach unlocks liquidity for farmers and suppliers by providing financiers with greater visibility and assurance regarding the underlying commodities and their movement.

The Liechtenstein Protocol is a decentralized compliance protocol developed by LCX, a regulated fintech company based in Liechtenstein. It’s designed to standardize the way security tokens and other tokenized assets are issued and traded on blockchains, with a strong focus on regulatory compliance.
The core of the Liechtenstein Protocol is a set of on-chain and on-token-level rules that can be embedded directly into a digital asset. These rules can automate compliance with a wide range of legal and regulatory requirements, such as those related to KYC (Know Your Customer) and AML (Anti-Money Laundering). Key services enabled by the protocol include on-chain asset management, which allows for the issuance, timelocking, and burning of tokens, as well as real-time tracking of a token's ownership through a "Token Holder Registry."
The Liechtenstein Protocol is blockchain-agnostic, but it has a key integration with the Hedera network leveraging the Hedera Token Service (HTS) to provide a secure, transparent, and compliant infrastructure for digital securities.

The Hashgraph Tower is a real estate investment platform that democratizes access to property ownership through fractionalization and tokenization. Its aim is to allow anyone to invest in real estate projects from anywhere in the world, with a focus on environmental sustainability and transparency.
The core of The Hashgraph Tower's service is its online platform, where investors can browse and purchase tokens representing a share in a specific real estate property.

The platform is designed to be a "hands-off" investment, with The Tower managing all aspects of the property and investment. Key features include a promised average profitability of 9%, no entry or exit fees, and the ability to resell tokens at any time.
All investment projects are registered on the Hedera distributed ledger, which provides a transparent and immutable record of ownership and transactions.
