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.

Capturiant, founded in 2022, is a Houston-based company that operates as a global environmental asset authenticator, registry, and marketplace. The company's mission is to bring efficiency, transparency, and trust to the historically opaque and fragmented environmental asset markets, including carbon credits.
The core of Capturiant's service is an integrated platform that manages the entire lifecycle of environmental assets. This includes the authentication and validation of projects that generate credits, the minting and registration of these credits on a digital registry, and a regulated exchange for trading them. By creating a transparent, private-sector-driven model with clear fee structures and robust standards, Capturiant aims to increase confidence and liquidity in the market.
Capturiant's entire platform is built on the Hedera network. The company utilizes Hedera's distributed ledger technology (DLT) to create an immutable and auditable record for every environmental asset it registers. By leveraging the Hedera Consensus Service, Capturiant ensures the integrity and transparency of all transactions, from the minting of a credit to its final retirement.
Stader Labs is a multi-chain liquid staking platform that provides a secure and efficient way to earn staking rewards while maintaining asset liquidity. It was launched in 2021 and has since extended its services across several major blockchain networks, including Hedera where it offers a liquid staking solution centered around the HBARX token.
When users stake HBAR tokens through Stader's platform, they receive HBARX, a liquid token representing their staked HBAR. This mechanism allows HBAR holders to continue participating in the DeFi ecosystem with HBARX, engaging with protocols including SaucerSwap and HeliSwap for additional yield opportunities, while still accruing staking rewards. The HBARX token is designed to increase in value relative to HBAR as staking rewards accumulate in the pool, with an auto-compounding feature managed at the smart contract level.
Stader Labs emphasizes security, subjecting its smart contracts to multiple third-party audits from firms such as Halborn, Peckshield, and Sigma Prime. The platform's architecture on Hedera aims to contribute to network decentralization by distributing staked HBAR across various nodes.

IOWNME is a platform developed by IPrivata, a company focused on data privacy and digital rights. Its designed to provide individuals with a way to assert ownership and control over their personal data, particularly in the context of name, image, and likeness (NIL) rights for athletes.
The core of the IOWNME service is the platform’s Declaration Certificate, a legally-grounded digital certificate that establishes a root proof of authenticity for an individual's data. This certificate links the rights embedded in a patent to an individual's personal information, effectively transforming the enforcement of data privacy from a matter of privacy policy to one of property rights, intellectual property, and contract law. This provides a more robust and proactive framework for individuals to protect and monetize their personal brand and content.
The IOWNME platform is built on the Hedera network. IPrivata is working directly with the Hedera Foundation and Acoer, a DLT developer, to integrate the Declaration Certificate into the Hedera ecosystem.

Power Transition is a UK-based clean technology company founded in 2018. Its focus is on accelerating the global shift to a zero-carbon economy by providing a smart software platform that optimizes and decentralizes energy systems.
The core of Power Transition's service is its Digital Energy Platform, a revolutionary energy resource management system that uses distributed ledger technology (DLT) to enable the tokenization of energy. This platform provides a common language for energy transactions and trading, allowing millions of devices, from electric vehicles to smart home appliances, to become active participants in the energy system. Key services include Smart MicroGrid Services, which enable peer-to-peer energy trading within a community, and Electric Vehicle Integration Services, which provide a single point of billing and data validation for EV fleet operators.
Power Transition's entire platform is built on the Hedera network. It leverages the Hedera Token Service (HTS) and the Hedera Consensus Service (HCS), Power Transition to tokenize and energy use, providing a transparent and auditable record of all transactions.
