Please describe your proposed solution

One of the factors to popularize blockchain is to integrate it with IPFS, a decentralized storage system that is highly compatible with blockchain. However, even though IPFS is highly durable and reliable as an alternative protocol to HTTP, its permeability is low because permanent storage is not guaranteed and anti-virus measures are required.

By combining IPFS with Arweave, which has rich data persistence, you can create the basis for building Cardano-specific storage. We analyze the configuration and mechanism of IPFS and Arweave, and create a configuration diagram/class diagram, an interface diagram between IPFS and Arweave, and a data migration condition blueprint as deliverables.

Based on the analysis results, if the configuration is feasible, we will store the blockchain in storage and create a prototype that can confirm permanent storage under arbitrary conditions. I think it will be possible to create a dedicated storage.

If it is not possible, we will create a report summarizing the analysis results and the reasons why it is not possible, and use this to lead to the next idea.

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

We will verify the compatibility between Cardano and IPFS. If this demonstration is successful, a dedicated storage service for Cardano will be realized. Additionally, since IPFS+Arweave has high security, if the demonstration is successful, we can expect Cardano to become more widespread.

This component can also be linked with "Masked NFT: Research on privacy data management by NFT," making it possible to combine data security with the large-capacity service of IPFS+Arweave.

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?

Axrossroad Co., Ltd. has 14 years of experience in system development and has received high praise from many customers.

Our strength is that we have experienced engineers who have completed the Plutus Pioneer Program sponsored by IOG Academy. They have the ability as Cardano smart contract developers and are actively involved in the development of "MetaDID Experiment", "Music Live NFT Platform", "Sustainable Apparel Trace", and "Monthly Report" adopted by Fund8 Catalyst. It is working. I was.

We have also developed an NFT marketplace compatible with Cardano as our own product, and have built up a track record. This not only contributes to the Cardano ecosystem, but also provides a valuable service to a wide range of users.

We have a team with expertise and experience in Cardano development, and we stay on top of new technologies and trends to provide innovative solutions. We promise to provide highly reliable services through flexible development and sound quality management tailored to customer needs.

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

Milestone 1: When managing chains, distinguish whether to store them in IPFS or Arweave based on file size and whether they are permanently stored.

Milestone 2: Create a service screen where files can be uploaded and build a prototype environment that users can access.

We will provide an API that allows you to separate storage based on the storage expiration type specified from the service screen.

Final Milestone: It will be a success if we can build a prototype of IPFS + Arweave storage service exclusively for Cardano blockchain.

The project will be completed successfully if we analyze the configuration and mechanism of IPFS + Arweave, summarize the design documents for the configuration, and submit a report.

Who is in the project team and what are their roles?

We will appoint a member as a product manager who has 20 years of system development experience and is good at task management and requirements organization.

As programmers, we will assign project members who have completed the Plutus Pioneer Program sponsored by IOG Academy. The programmer has experience developing FUND8 and also has a track record of developing Cardano.

Please provide a cost breakdown of the proposed work and resources

Total 43068 ADA

Mission1 Investigation&verification 21104 ADA

Misson2 Web application creation 16500 ADA

FInal Testing&Documentation 5464 ADA

In order to plan a new storage service using IPFS and Arweave, we first investigate how IPFS and Arweave work and are configured. IPFS and Arweave are used when prototyping, so the mechanisms for storing data in IPFS and Arweave are not open source.

How does the cost of the project represent value for money for the Cardano ecosystem?

If this mechanism is successful, files can be stored safely without worrying about data size or usage fees. By working with Masked NFT<https://cardano.ideascale.com/c/idea/112944>, blockchain can revolutionize the confidentiality of data and data storage in applications.
