[SOLUTION] Please describe your proposed solution

We aim to solve issues by storing information on the Cardano blockchain. Once information is recorded on the Cardano blockchain, it cannot be lost. Additionally, we would like to explore adding a system that provides incentives to protect this information. Furthermore, if access to the key is not restricted to the individual alone, we will also study how to define or set the conditions for unlocking the key. Below are examples of representative services.

1. Document Storage: Storing text-based information is easy due to its relatively small size.
2. Financial Information Storage: Storing monetary or financial data as personal information.
3. Security Storage: Safely storing IDs and passwords.
4. Emotion Storage: Storing emotions and feelings as text or photos.
5. Time Capsule: Storing information as a time capsule for families or schools.

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

We record various important information on the Cardano blockchain, which has been operating continuously without interruption since its launch. By doing so, we contribute to society, including individuals and businesses, by ensuring the information is safely and accurately preserved permanently.

[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?

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

（My job is developing broadcast related equipment for a measuring instrument manufacturer. I also develop Dapps on public blockchain.

■TAKAHIRO UNNO

I was a software developer of broadcast systems at Panasonic. I was designing and developing dedicated broadcasting equipment, system control and management, and system monitoring using a real-time OS. Currently, I am also engaged in web development with Node.js and developing a new blockchain-based social information system.

[BUDGET & COSTS] Please provide a cost breakdown of the proposed work and resources

Milestone 1 [50K ADA]

•  technical experimentation  30K ADA
• information display processing 20K ADA

Milestone 2 [85K ADA]

•  blockchain implementation 30K ADA

[VALUE FOR MONEY] How does the cost of the project represent value for money for the Cardano ecosystem?

We assume that the information we wish to preserve will primarily be in the form of text documents. A single type of document file will be stored in each transaction. Therefore, if there are many types of documents to be preserved, we expect a corresponding number of transactions. Additionally, since updating the information requires new transactions, updates will also be important.
