The purpose of this project is to build a new platform that utilizes IPDC (broadcasting) and the Cardano blockchain to actually broadcast a block-based signal over television airwaves. We will build a new integrated platform that can transmit CARDANO block information safely and quickly with high reliability, and conduct a field demonstration using actual television airwaves. In addition, we will create an opportunity to widely raise awareness of the CARDANO blockchain through the influence of Japanese television (= mass media).
At its core, the project includes field demonstrations by broadcasting stations to evaluate how broadcasting and blockchain technologies can work together in real-world environments to ensure reliable distribution and authentication of information. Ultimately, the goal is to establish a public information infrastructure that guarantees authenticity and is equally accessible to all.

(1)Platform Design and Building
In the initial phase of the project, platform design and building will be intensively carried out within a defined timeframe, utilizing IPDC and the Cardano blockchain. This platform will serve as a prototype of public infrastructure, equipped with functions for distribution, reception, recording, and verification of critical information such as disaster alerts and official communications.

(2)Field Demonstrations and Technical Validation by Broadcasters
Participating broadcasters will carry out field demonstrations using actual IPDC signals, validating the technical feasibility and operational aspects of blockchain-based distribution and verification. This process will provide key insights for institutional design, standardization, and real-world deployment.

(3)Social Implementation and Sustainability via a Co-Creation
A co-creation consortium will be formed consisting of multiple broadcasting stations and related companies. By working to develop services and resolve regional issues, the consortium aims to expand the platform nationwide as a reliable public infrastructure and ensure its sustainable operation into the future.

(Additional information) Regarding the cost of building the platform
To build this platform nationwide in Japan, it is necessary to introduce it at broadcasting stations in all 47 prefectures. Approximately 60 million yen is required for each location. Because Kanto and Kansai are special, we will introduce it at about 40 locations, and 40 x 60 million yen = 2.4 billion yen is required. This time, we will limit it to three broadcasting stations and introduce a minimum system at each location for 18 million yen. We are assuming one location at Milestone 2 and two locations at Milestone 3.

Rising Social Demand for Trustworthy Information Distribution
[Problem to Solve] Information that demands high integrity - such as disaster alerts, public notices, and certifications—is vulnerable to manipulation, misinformation, or delivery failure in current communication systems. These risks are especially critical during emergencies or network outages.

he importance of ensuring reliability even in peacetime
[Problem to Solve] Conventional broadcasting and internet systems operate in isolation with little integration. It is difficult to find reliable information in the internet environment, reliability in peacetime is also important in times of disaster.

Need for a Sustainable Public Information Infrastructure
[Problem to Solve] Regions affected by disasters, aging populations, or rural depopulation struggle to maintain stable and equitable access to information infrastructure. Current internet/cloud-based models are often urban-centered, costly, and fragile.

Rising Social Demand for Trustworthy Information Distribution
[Benefits of problem solving]
This project solves the problem by integrating the broad reach of IPDC broadcasting with the immutability and verifiability of Cardano blockchain, enabling a reliable and tamper-proof information delivery infrastructure for all.

The importance of ensuring reliability even in peacetime
[Benefits of problem solving]
This project will achieve these goals by combining broadcasting technology and blockchain technology. As the world's first integrated broadcasting and Web3 infrastructure, we maximize the public credibility of the CARDANO blockchain by using broadcast block information as a reference signal.

Need for a Sustainable Public Information Infrastructure
[Benefits of problem solving]
This project provides a low-cost, resilient, and inclusive information platform by leveraging the robustness of broadcast technology and the decentralized nature of blockchain, offering a sustainable public infrastructure for all communities.

We have been working in the broadcasting industry for 25 years, developing, implementing and operating transmission systems within broadcasting stations. We have also been working on research and development of IPDC together with broadcasting stations for the past 15 years. Furthermore, last year we began basic development at Caltalyst (Fund12).

We work with broadcasting station systems to automatically monitor legitimacy and ensure continuous operation. We also perform regular maintenance of transmission systems. We also ensure continuous operation of receiving systems, including building prototypes as necessary.

1. Strong Public Demand for Trustworthy Information Distribution There is a strong and widespread need for accurate and trustworthy information delivery, particularly in critical areas such as disaster alerts, government notifications, and digital certifications. This need is especially pressing among local governments, residents in disaster-prone areas, the elderly, and institutions with limited access to robust internet infrastructure.

2. Community Resonance with an Open and Co-Creative Platform Model The project’s open, decentralized, and co-creative approach has drawn support from engineers, researchers, local governments, and community organizations. Its commitment to transparency, neutrality, and public interest—rather than corporate control—resonates strongly with a wide range of stakeholders.

3. Practicality and Reliability Through Existing Infrastructure Utilization By leveraging existing broadcast and IPDC infrastructure, the project avoids the high costs of new construction and offers a realistic, scalable, and low-barrier solution. This practicality enhances its credibility and attractiveness to infrastructure stakeholders.

Cooperation from TV broadcasters is essential. New transmission systems need to be installed for the field experiment, and existing systems need to be reconfigured. Human and technical resources need to be allocated for the field experiment.
