Hedera Coinflip
Hedera Coinflip is a decentralized application (dApp) built on the Hedera network that offers a simple, "double or nothing" style betting game. Users can wager HBAR for a 50/50 chance to double their bet. The platform's core value proposition lies in its commitment to transparency and fairness, which is achieved through its unique use of the Hedera Consensus Service (HCS).
The fairness of each flip is guaranteed by a provably fair mechanism that prevents manipulation by either the player or the platform operator. When a user initiates a flip, a combination of a server-provided seed and a client-provided seed is submitted to the Hedera network via HCS. The immutable and unpredictable consensus timestamp assigned to this transaction by the decentralized network is then used to determine the outcome. Because this timestamp cannot be influenced or known in advance, the result of the coin flip is truly random and publicly verifiable.
A small percentage of each wager contributes to a progressive jackpot, which can be won by players who achieve a specific, consecutive number of wins. This jackpot serves as the platform's primary revenue model while also creating an exciting, high-reward target for dedicated players.

Gaimin is a Swiss-based company founded in 2018. Its vision is to create the world's most powerful decentralised supercomputer by harnessing the collective power of the gaming community.
Gaimin's core product is a free-to-download PC application that runs in the background, detecting when a user's computer is idle and then utilizing its processing power for various tasks, such as AI model training, video rendering, and blockchain computations. In return for contributing their resources, gamers are rewarded with Gaimin's native cryptocurrency, GMRX. This creates a passive income stream for gamers and provides a cost-effective solution for businesses in need of high-performance computing. The Gaimin platform also serves as a game launcher and a hub for Web3 gaming, with an integrated marketplace for NFTs and other digital assets.
Gaimin uses the Hedera network to tokenise in-game assets as NFTs, allowing players to have true ownership of their digital items. One of the first games to be integrated with this system is a version of Minecraft called Gaimcraft, where users can create NFTs that are interoperable between the Gaimin marketplace and their Minecraft inventory.

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.
