Tokenized digital signage: 100% transparent, zero intermediate fees. On-chain content moderation is ready for real-world use.
📢Introduction📢
Tokyo is a city full of advertisements, with people encountering between 5,000 to 10,000 ads daily. However, the advertising industry is often closed off and lacks transparency, with large ad agencies controlling the majority of billboards. Our goal is to revolutionize the city's advertising landscape, beginning with digital signages in Tokyo.
💡Our Solution 💡
We have created a tokenized, fully on-chain digital signage solution. Each digital signage device in the city is assigned a unique token. To advertise on a digital signage, simply follow these steps: 1. Purchase the associated token, 2. Upload an advertisement NFT, and you're all set!
Advertisement Control: Ensuring that only those who have purchased the signage token can control the advertisement content on the signages is crucial. To achieve this, we have developed a web3 application that works on digital signage IoT devices. The signages then retrieve advertisement content from the blockchain.
Content Moderation: Advertisements serve as public goods, making content moderation essential. We have addressed this issue by implementing a fully on-chain identity and social credibility verification system, powered by Worldcoin and Lens Protocol. This ensures that only appropriate content is displayed on the digital signages.
Deployment simplification: To make our digital signage application work efficiently, we required two sets of smart contracts: one for the signages and another for the advertisements. In order to manage these contracts without cluttering the codebase, we utilized Bunzz. Thanks to Bunzz, our dApps can be deployed in a one-stop manner, streamlining the entire process.
