Standard Grant Proposal: DartSia Mobile App

Standard Grant

Project Name: DartSia Mobile App

  • James Brel tamegno
  • Egoume Mouyong Rekiyatou

Project Description :

Dartsia is a mobile application which aims to allow users of the sia ecosystem to access a Renterd node and be able to interact with it. The Sia application platform is full of a wide range of software to enable the storage and sharing of data and among these software, renterd is the most efficient. Renterd allows users to store data on the Sia network and also to be able to interact securely with the network, but the problem that arises in turn comes from the fact that users of mobile devices do not have the possibility of access the network from their phone. It is for this reason that we considered creating an application that would allow easy access to a renterd node (even for novice users) while ensuring the security of their data.

The initial idea of the project was to develop a dart package coupled with middleware which would facilitate the development of mobile applications on the Sia platform but after discussion with the Sia foundation team, we focused on the development of the mobile application by giving it the same name again. During the first phase of development, we realized the difficulty represented by communication between the renterd software and the mobile application. As a result, it was necessary for us to develop, in addition to the mobile application, a Go middleware functioning as a request handler to intercept, secure and redirect requests to the Renterd API.

For us, during this grant, it will be a matter of developing both an intuitive and easy mobile application for ordinary users and a middleware that will manage and secure all the requests for our application.

Who benefit from your project :

The project mainly benefits all users of the Sia network. It gives them the ability to control their renterd nodes, have data on the state of the sia network and also on the operation of other nodes in the network.

How does the project serve the Foundation’s mission of user-owned data?

The project allows the Sia Foundation to strengthen its capacity to develop decentralized applications for users of mobile devices. It thus gives the foundation a fantastic opportunity to extend its user data management functionalities.

Grant Specifics

Features to be delivered :

  • Login : Be able to connect to a rented host using its IPv4 or DNS address and password.
  • Network Overview : This functionality allows you to display real-time data on the state of the Sia network as well as its interactions (Numbers of active hosts, Total Network storage, Total used storage, Storage Price per TB)
  • Host Research : This functionality allows you to list all the hosts available and active on the network.
  • Show Host informations : This feature allows you to display all of the host’s information as well and its scoring.
  • Active Hosts Notifications : This feature allows you to receive notifications about changes in the status of a host.
  • File sharing : This feature allows you to share a file with an access link.
  • My Host Overview : Allows you to display the operating information of your host and see its operating status

Additional Charges (Electricity/Internet) $100

Potentials risk to the project :

The potential risks that can affect the completion of our project can be numerous and varied. Here are some of the most common risks:

Financial risks: This includes project budget overrun, exchange rate fluctuations during monthly payments, unexpected costs related to cloud resource consumption, etc.

Risks linked to deadlines: Delays in the development of the modules of our package, planning problems over the duration of the milestones, unforeseen difficulties can lead to delays in the completion of the project.

Human Resources Risks: This includes loss of key team members, internal conflicts, competency issues, etc.

Technical risks: Problems related to technology (framework to use, external packages, etc.), tools, equipment, software or hardware can affect the progress of the project.

External risks: This includes unforeseen events such as illness, legal or regulatory changes, political issues, etc.

It is essential for the success of a project to properly identify, evaluate and manage these risks throughout its implementation.

Thanks for your proposal to the Sia Foundation’s Grants Program! The committee is requesting an update to this proposal in order to fully consider it.

  • You need to provide an actual timeline for your project. Estimates are fine, but you should be able to tell the committee what’s happening, when it’s happening by, and how long the overall project will be.

The committee believes this proposal can be updated to accurately reflect this change, and so we’ll leave this in the Proposed category for now. Please update accordingly and the committee will re-evaluate. Thanks!

Hello Steve and thank you to the foundation for the consideration. We have update the proposal and the complete timeline are available here :

We hope that with this latest additional information, the committee will finally be able to fully study our grant request.

We’ll reach out to your provided email address to begin onboarding. It can take a couple of weeks to get new grantees set up, so please adjust your timelines accordingly. We’ll contact you after onboarding is complete to get the updated timeline and milestone target dates.

Hello Steve and thanks to the sia grant committee for approving this proposal. We will update the timeline and begin the work on next week. We also waiting the onboarding email to advance in formal process.

Hello @innovtech,

This is a reminder that your April progress report is now late.

Please be sure to follow the Progress Report Template and submit your progress report so we may continue funding your grant.

Kino on behalf of the Sia Foundation and Grants Committee

Hello Kinomora,
In agreement with Frances, our first report must be sent on June 2. We took several weeks for onboarding between identity checks and late payment.
Thank you very much.


Progress made on our grant this month?

During this month, we mainly worked on optimizing the architecture of the application to be able to operate using the Go middleware that we will start to develop to facilitate and secure communications between the application and the renterd server.

We also work on the bucket and file management page. We end the design of the page and finish the devellopment on the functionnality on the application.

Problems Encountered during the work

During this phase, we did not encounter any major problems apart from the time it took to put our development servers back into service.

Links to repos worked on this month:

What will you be working on next?

For the next month, we will mainly work on finalizing the file management part by integrating the S3 API into our application.
We will also try to work on the application’s notification and alert system.

Hello @innovtech ,

Thank you for your progress report!
