Attestiv is a digital media validation company founded in 2018 to combat the rising threat of deepfakes and AI-generated content. Headquartered in Utah, the company provides solutions for businesses that rely on the authenticity of photos, videos, and documents, with a primary focus on the insurance, cybersecurity, and financial services industries.
The core of Attestiv's offering is its AI-powered platform that analyzes digital media to detect alterations, tampering, and generative AI content. The platform provides a "tamper score" to indicate the likelihood of manipulation and can identify specific anomalies through a forensic scan. This technology is delivered through a suite of products, including APIs and SDKs that can be integrated into existing workflows, as well as a user-friendly dashboard for manual analysis. Attestiv's solutions are designed to automate fraud detection, streamline processes like insurance claims and underwriting, and protect businesses from the reputational and financial risks associated with fake media.
Attestiv uses a distributed ledger to create a "digital fingerprint" that is recorded on the Hedera blockchain network. This allows for the immutable and verifiable timestamping of each asset, ensuring its authenticity can be validated at any point in the future.
The eftpos solution by Australian Payments Plus provides a cost effective, secure and flexible payment infrastructure for Australian businesses. It supports real time debit transactions, tap to pay on mobile devices, eftpos QR payments and least cost routing, which allows merchants to automatically direct debit transactions through the lowest cost network to help reduce the cost of acceptance.
Australian Payments Plus has worked with Google to enable least cost routing in Google Wallet, with ANZ and Suncorp the first issuers to offer this capability. It is also partnering with Giesecke and Devrient to develop eftpos Click to Pay with integrated least cost routing, an online checkout service that uses tokenisation to protect card credentials and is scheduled for rollout from early 2026 following pilot trials.
These developments enhance payment efficiency, improve security, support domestic data sovereignty and align with Reserve Bank of Australia findings that least cost routing can materially reduce merchant debit acceptance costs.

C14 is a financial technology company that provides a seamless fiat-to-crypto on-ramp solution for developers building on the Hedera blockchain network. Its core product is an easily embeddable widget that decentralized applications (dApps), wallets, and marketplaces can integrate directly into their platforms.
With C14's widget, users can purchase digital assets directly within the dApp they are using, employing familiar payment methods like credit or debit cards. The platform handles the entire transaction flow, including regulatory compliance aspects like Know Your Customer (KYC) checks, and delivers the purchased assets directly to the user's connected wallet. This creates a simple, "one-click" experience that significantly lowers the barrier to entry for mainstream adoption.
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.
