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.

REVEL Moments is a live, virtual storytelling platform that aims to create authentic connections between athletes and their fans. The company's mission is to go beyond the on-field persona and showcase the "human behind the athlete" by hosting curated, interactive events where sports figures can share untold stories and personal experiences in an intimate setting.
The core of REVEL's service is its live, professionally moderated virtual events. These are not typical interviews; they are interactive experiences where fan input helps shape the content. Fans can submit questions beforehand and engage with the athlete and other attendees through a live chat, with some even getting the opportunity to join the virtual stage. This model provides a unique form of fan engagement that is more personal and unscripted than traditional media appearances. The platform serves a wide range of athletes, from retired legends to current professional and student-athletes.
Tickets for REVEL's events are issued as NFTs on the Hedera network, allowing fans to own a digital collectible that represents their participation in a unique experience.
The Hyperledger Fabric plugin for Hedera Consensus Service (HCS) enables Hyperledger Fabric networks to utilize the Hedera public network for transaction ordering. This plugin allows developers to replace or augment traditional Fabric ordering services such as Raft or Kafka with HCS, leveraging Hedera's asynchronous Byzantine Fault Tolerant (aBFT) consensus mechanism.
The core function of the plugin is to have Fabric orderer nodes submit endorsed transactions to a designated topic on the Hedera Consensus Service. HCS then assigns these transactions a unique, immutable, and verifiable consensus timestamp and sequence. Fabric orderers subscribe to this topic via a Hedera mirror node, retrieve the ordered transactions, and use this sequence to consistently form blocks and propagate them within the private Fabric network.
By integrating HCS, Hyperledger Fabric applications gain several benefits including enhanced trust and decentralization in the ordering process, public verifiability of transaction sequences for increased auditability, and potentially reduced operational complexity compared to managing a traditional private ordering service.
