Chainlink
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.

Hala Systems is a social enterprise founded in 2015 that develops advanced technology to protect civilians in conflict zones. Its mission is to reduce violence and provide accountability through the creation of early warning systems and tools for documenting war crimes.
The company's flagship product is Sentry, an AI-powered early warning system that predicts and warns civilians of impending threats, such as airstrikes. Sentry uses a network of remote sensors and real-time data to provide warnings, giving people crucial time to find safety. The system has been deployed in Syria, where it has been credited with significantly reducing casualties. In addition to its warning capabilities, Hala Systems also focuses on accountability, developing tools that allow for the secure collection of evidence of war crimes.
To ensure the integrity of the data collected, such as photos and videos of potential war crimes, Hala uses the Hedera Consensus Service (HCS) to create a tamper-proof and cryptographically secure record of the evidence. Each piece of media has its metadata logged on the Hedera network, creating a verifiable and immutable audit trail.

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.

Fireblocks is an enterprise-grade platform that provides secure infrastructure for moving, storing, and issuing digital assets. Founded in 2018 and headquartered in New York, it has become a leading provider of digital asset custody, transfer, and settlement technology for a wide range of financial institutions, including banks, hedge funds, and crypto exchanges.
The core of Fireblocks' service is its institutional-grade platform that combines multi-party computation (MPC) with hardware isolation to create a highly secure environment for managing digital assets. The platform also features the Fireblocks Network, a secure and efficient network for connecting with over 1,800 liquidity partners, trading venues, and counterparties.
Fireblocks is deeply integrated with the Hedera network, providing comprehensive support for HBAR and other Hedera-based assets. It also supports the Hedera EVM, enabling clients to interact with Hedera-based smart contracts and decentralized applications. Furthermore, the Hedera Guardian, an open-source platform for ESG assets, can be integrated with Fireblocks, allowing for the secure, remote signing of transactions.

ConsentCheq, a service by PrivacyCheq, is a consent management platform that helps businesses comply with global privacy regulations such as GDPR, CCPA, and COPPA. Since its launch in 2016, the company has focused on providing a "single source of truth" for user consent, enabling enterprises to manage and honor user privacy preferences in real-time across all their systems.
The core of ConsentCheq's service is a full-stack transparency and consent management solution. It provides tools for businesses to deliver clear privacy notices and to capture, log, and manage user consent for data collection and processing. A key feature is the "Consent Dashboard," a centralised interface where users can view and control their privacy settings for any business that uses the ConsentCheq service. The platform also offers "Consentive," an incentive-based system where consumers can be rewarded with micropayments for granting consent, which is designed to increase opt-in rates for data processing.
ConsentCheq's connection to the Hedera network is central to its "Consentive" service. The platform uses the Hedera Consensus Service (HCS) to create a high-throughput, low-cost, and auditable log of consent verification and payment events. Under privacy laws, advertising networks must verify consumer consent each time they process or track them.
