[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 will develop and test a simple donation/voting system that takes advantage of eUTXO's multi-address design and multi-token design, which are one of Cardano's features.

[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.”

In this project, the pilot test to use multi adrress is important. Therefore, the place for the test(tabino otomo cafe) is necessarry. In order for the café to continue to function as a testing site, it needs Japanese subsidies. For this reason, the implementation location may change depending on the application status of the subsidy project. The company also plans to outsource development to an outside company.

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

No

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

The product tool will be release as an application system. Everyone can use this system. The source code itself will not be open immediately but there is a possibility to open in future plan.

[SOLUTION] Please describe your proposed solution

Answer:

By using the multi-address management system and wallet function adopted by Daedalus, Yoroi, etc., multiple accounts using multi-addresses, which are thought to be used at exchanges, etc., can be managed with one wallet. At the same time, we will develop a system that allows holders of each address to receive and utilize points based on the content of their transactions. Furthermore, we will verify whether this system can be applied to a donation system at social welfare facilities.

background

Cardano includes 1.2 ADA when sending tokens. This may not be a problem for some traders who trade large amounts of money, but new users are often confused. Additionally, the Locked ADA display is difficult to understand. This problem is particularly pronounced with NFTs, where a significant amount of ADA is locked up in NFTs and tokens. I understand that this measure is included for security reasons.

Due to these problems, it is technically easier to develop a service that involves direct ADA sending. However, various functions cannot be provided only with the payment function of crypto assets. Therefore, in the future, we expect transfer fees to be paid by specific tokens or a vote to abolish associated ADA. (BABEL Fee model) However, we believe that the BABEL Fee model will not be put into practical use unless we stimulate demand for tokens in Cardano and increase the value of tokens by developing services equipped with token functions ahead of the current situation.

One of the advantages of Cardano is highlighted as easy money transfer with low fees and free token issuance, but these advantages are negated by the ADA attached to the token. Furthermore, it will also hinder the operation of simple systems that use tokens.

To address these issues, we would like to make efficient use of the added 1.2ADA, eliminate the disadvantages of Cardano, and emphasize the advantages of multi-address, which makes managing tokens very easy. . However, in such proposals, it is necessary to verify the practicality of the system.

On the other hand, there are social welfare issues surrounding handicapped individuals who, for some reason, have difficulty doing regular work. Subsidies are being developed in various countries to address this issue. On the other hand, it is the Handicapped Person's own wish that their work be evaluated fairly. For example, in design work, people want their work to be legitimately compared with the designer's work. Depending on each person's preferences, in certain cases, there is a possibility that one's own work will receive a higher evaluation than that of the designer. However, if the vote is for a charity or other event where the person is identified as a Handicapped Person, it cannot be confirmed that the evaluation is legitimate.

A sales method that eliminates these problems is called a blind sale, in which all works are mixed together and sold at regular stores. The same applies to mail order and the like.

Solution

One possible way to use anonymity in blind sales and other events to obtain fair evaluations is to apply anonymity through blockchain. Specifically, crypto addresses can be used to vote on designs and give away chips. In this case, in a normal system, it is necessary to cover multiple addresses as a management system. However, in the case of Cardano, it is possible to easily manage all deposit information by using a wallet such as Yoroi or Daedalus. At the same time, even if tokens are used, the Token balance will be integrated and the accompanying ADA will be 1.2 ADA in total. Furthermore, 1.2ADA can also be released by sending money to the original token holding address.

In this project, we will develop a point system that utilizes the UTXO of the wallet in order to take advantage of these characteristics of the Cardano wallet.

Specifically, we plan to develop a system that will allocate addresses to each producer and award points to each producer by referring to UTXO information at each address. By creating an account, producers can easily check the content of tokens sent to them.

What must be noted here is that this system itself can be easily implemented using only a wallet and the currently available Cardanoscan functions. Therefore, there is no need to spend a large amount of money to develop this system. However, if there is a system that reduces the usability of Cardanoscan functions and the complexity of the management system, it should be possible to more easily build a point system using Cardano tokens.

Based on this, this project will first conduct a trial run of the point system, mainly manually, and detect any problems. Take advantage of charity events, etc. This is also to promote that Cardano is used as a base system. After the problem detection is completed, we will develop an application that can be used as a point system and use it again at events to test the usability. The project provides usage reports for the application and each event.

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

This project provides the cost-saving benefits of using Cardano. It also provides practical examples of tokens based on social welfare. These examples will serve as a track record when promoting Cardano in the future. Furthermore, by making the application public, it is possible to significantly reduce the initial cost of subsequent projects. We would like to support the creation of blockchain projects using Cardano with as little capital as possible.

[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 concept of this project is to prove that anyone can start a project using Cardano-based blockchain. At the same time, the purpose is to promote Cardano's suitability for solving social problems.

For this reason, this project will make maximum use of already available Cardano products, except for the application system that will be developed by outsourcing. For example, tools such as Daedalus Wallet, Yoroi Wallet and Cardanoscan.

In implementing this project, it is necessary to sympathize with Cardano's philosophy. It is also important to develop services using Cardano from a state with little technical knowledge of blockchain. Of course, we will take advantage of advice from the Cardano community. However, the most important thing is the experience of working closely with social issues over many years. With minimal development, using blockchain directly in your efforts can also be an inspiration for other projects.

Furthermore, facilities that can be deployed at any time for events and other events are also important. Based on these considerations, we believe that the project manager has a very good background and conditions.

[PROJECT MILESTONES] What are the key milestones you need to achieve in order to complete your project successfully?

Token distribution and voting experiments at events

In order to utilize the multi-address system in this project, we will distribute tokens to some users and ask them to vote. The voting results will be aggregated using Cardanoscan and the voting results will be communicated to the producers. Analyze event reports and create a design document for application development in Milestone2.

Application design document

Multi-address system development

Develop the application based on the design document created by referring to the results of Milestone 1. Development will be outsourced to an external company, but the company will select a company with which it can actively collaborate to check operation. We also place importance on understanding and empathy towards Cardano.

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

We are also aiming to expand the actual use cases of Cardano by promoting the results of this project to other social welfare organizations and enabling low-cost implementation.

We believe that providing examples of social welfare contributions in Japan and providing applications for that purpose will be important for the future development of Cardano, and that we can provide value for the cost.
