AdsDax is a digital advertising platform founded in 2013 that aims to solve endemic problems in the advertising industry, such as fraud and a lack of transparency, by removing intermediaries and fostering direct, value-based connections between brands and consumers.

‍

The core of AdsDax's service is a self-serve advertising platform that allows brands to create, buy, and sell advertising in a transparent environment. A key feature of their model is the use of incentivised experiences, where consumers are rewarded with digital assets for their engagement with advertising content. This approach, which leverages AI for campaign optimization, is designed to move beyond superficial metrics such as "likes" to drive authentic engagement and build brand loyalty. The platform supports a variety of ad formats, including interactive and video ads, and is utilised by major advertising agencies.

‍

AdsDax uses the Hedera Consensus Service to track and verify millions of advertising events such as impressions, clicks, and conversions in real-time. Each event is recorded on the Hedera public ledger, creating an immutable and auditable trail that provides a single source of truth for advertisers and publishers. This allows for the automated and near-instantaneous settlement of payments to publishers and rewards to consumers using cryptocurrencies.

Starling Lab for Data Integrity is an academic research center that operates at the intersection of cryptography, decentralized web protocols, and the humanities. A joint initiative between the USC Shoah Foundation and Stanford University's Department of Electrical Engineering, the lab's mission is to develop and prototype tools and principles to establish trust in digital records. In an era of rampant misinformation and AI-generated content, Starling Lab is pioneering new methods to securely capture, store, and verify digital media.

‍

The core of their work is the Starling Framework for Data Integrity, a comprehensive, open-source methodology for authenticating digital content. This framework is built on three pillars: Capture, which involves creating a chain of custody from the moment a photo or video is taken, Store, which uses decentralized networks like IPFS and Filecoin to securely distribute and preserve content, and Verify, which leverages immutable ledgers to register and audit the provenance of digital assets. This end-to-end approach has been applied in various real-world scenarios, from documenting the 78 days of the 2020 U.S. presidential transition with Reuters to preserving the USC Shoah Foundation's archive of 55,000 holocaust testimonies.

W3C Decentralised Identifiers (DIDs) are a new type of globally unique identifier designed to enable verifiable, decentralised digital identity. As a formal web standard published by the World Wide Web Consortium (W3C), the DID architecture is a foundational component for building a more secure and user-centric internet.

‍

Unlike traditional identifiers such as email addresses or usernames, DIDs are not tied to any centralised registry or company. This means that individuals and organisations can create and control their own identifiers, giving them "self-sovereign" control over their digital identities. The core of the system is the DID Document, a JSON file that contains the cryptographic keys and service endpoints associated with a DID. This document is stored on a distributed ledger or other decentralised network, allowing for secure and verifiable interactions.

‍

The Hedera Consensus Service (HCS) is used to create a tamper-proof and auditable log of all DID-related events, such as creation, updates, and revocation.

Siki is a Los Angeles-based company founded in 2021 that is building a multimedia and social platform centered around music and NFTs. The company's mission is to create a more sustainable entertainment ecosystem where artists and curators can directly monetize their work and engage with their communities in new ways.

‍

The Siki platform combines several key services into a single social ecosystem. It functions as an NFT music streaming service, allowing artists to mint their songs as NFTs and earn higher royalties compared to traditional streaming platforms. It is also an NFT marketplace, where users can buy, sell, and auction these music NFTs. The platform is designed to be a social hub where users can connect with each other and their favorite artists, with features like tipping and live streaming integrated directly into the NFT experience.

‍

The Hedera Token Service (HTS) is used by artists on the Siki platform to mint their music as NFTs. This allows for efficient and low-cost creation and transfer of these digital assets. By building on Hedera, Siki can provide a secure, scalable, and environmentally friendly platform for its users to stream, trade, and engage with music in a novel way.
