[GENERAL] Name and surname of main applicant

ATTRACTOR Co., Ltd. (Jun Hamada)

[GENERAL] Are you delivering this project as an individual or as an entity (whether formally incorporated or not)

Entity (Incorporated)

[GENERAL] Please specify how many months you expect your project to last (from 2-12 months)

8

[GENERAL] Please indicate if your proposal has been auto-translated into English from another language

Yes

[GENERAL] Summarize your solution to the problem (200-character limit including spaces)

We enable blockchain authentication even in places without internet access by transmitting information over broadcast infrastructure.

Especially when disaster strikes, this solution promises safety.

[GENERAL] Does your project have any dependencies on other organizations, technical or otherwise?

Yes

[GENERAL] If YES, please describe what the dependency is and why you believe it is essential for your project’s delivery. If NO, please write “No dependencies.”

This service is a cooperative venture with broadcasters. We create new social value by collaborating with broadcasters who are engaged in socially influential TV services. If necessary, we can also create our own broadcasting airwaves.

[GENERAL] Will your project’s output/s be fully open source?

Yes

[GENERAL] Please provide here more information on the open source status of your project outputs

The source code developed under this proposal will be released as open source software (OSS). We plan to offer it as a GPL license.

We will make this activity transparent as we implement it. Furthermore, we aim to broaden the scope of its use to a wider audience. In addition, we hope to form new communities in the future.

[METADATA] SDG rating

We aim to create a society where people with limited information literacy, such as children and the elderly, can live safely and securely..We aim to achieve the following three Goals.

Goal.9 : Industry, Innovation and Infrastructure

We leverage traditional, public digital broadcasting (broadcast infrastructure) and integrate it with the new Web3 world of blockchain to achieve social innovation.

Goal11 : Sustainable cities and communities

Malicious attacks and identity theft occur throughout the world of the Internet. For a livable environment, correct order is important for information. Through this initiative, we will realize social innovations that can publicly authenticate the correctness of information.

Goal16 : Peace, Justice and Strong Institutions: 

Our mission from a global perspective is to create a peaceful society. To achieve this, it is essential to collaborate with broadcasters who broadcast public information, and we will realize social innovation to build an impartial platform for the next era.

[SOLUTION] Please describe your proposed solution

We will build this new public authentication platform by using the highly public broadcast airwaves for information distribution.

By combining broadcast transmission technology with blockchain technology, we can build a social authentication platform, which will help solve social issues by socially realizing the independent and decentralized structure that Web3 aims to achieve in the future.

For example, during a large-scale disaster, the Internet environment is lost, resulting in fake information and fake authentication by malicious people. It is precisely in emergency situations that orderly and correct authentication is necessary, so that affected residents can act with peace of mind.

==========

[Background]

Features of Broadcasting Airwaves

Feature 1

We use the current airwaves as they are.

We use the infrastructure (=radio waves) that already exists for TV services. We can transmit information to places where we can receive television services.

Feature 2

One-way transmission environment that cannot be tampered with.

There is no intrusion or tampering of information by third parties. Therefore, people can recognize that the information they receive from broadcast waves is correct, and can act with peace of mind. Therefore, it is suitable for distributing public information.

Feature 3

Robust transmission equipment, strong radio waves

The transmission equipment can withstand disasters, so even if a disaster occurs, broadcasting will continue.

(If a problem occurs, the broadcasting station will take care of it.)

Feature 4

Since it is a traditional media, it is widely used, including among the elderly.

The receiving STB is always receiving, so there is no need to select stations and information is always available.

Feature 5

Transmission of IP packets in TS (Transport Stream)

Television broadcast waves have been made more sophisticated by the method of transmitting IP packets within the Broadcast Protocol (TS) (=IP datacast=IPDC).

Feature 6

After receiving information, data linkage is possible.

It is also possible to connect to smartphones and IoT devices from the broadcast airwaves. We are promoting linkage with blockchain.

We started research and development 12 years ago and succeeded in the first service in 2017 = Public Signage (push display of municipal information by broadcasters to municipal facilities)

　　

[IMPACT] Please define the positive impact your project will have on the wider Cardano community

This platform is a social impact initiative. Public and traditional television (TV) services such as digital terrestrial broadcasting, digital satellite broadcasting, and cable broadcasting exist as a traditional public and vast infrastructure. We can use this broadcasting infrastructure simultaneously with TV services to transmit information. By transmitting public information over the most secure infrastructure, we can create new value. By integrating with the stable Cardano platform, we believe that this platform can grow as a social system. Therefore, we expect that transactions for authentication will occur for many people and in many situations.

[CAPABILITY & FEASIBILITY] What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

We have 25 years of experience specializing in broadcast technology. In addition, our new IPDC project utilizing broadcast radio waves has been proven through 12 years of research and servicing. In Japan, it was adopted by the Fire and Disaster Management Agency as a new means of communicating information during disasters.

Furthermore, it has been proven by blockchain experts to a technology proof of concept (PoC) in 2023, allowing us to implement the next phase of platform building.
