Proposal: Storage solution on Polkadot

  • Team Name: Eiger
  • Payment Address: Fiat 14.04.2023, 16:50 UTC+3
  • Level: 2

Project Overview 📄


The main goal is to implement and maintain a Filecoin-like system parachain that uses DOT as the native token and is easily usable for all kinds of parachain projects in the ecosystem via XCM.

Project Details

To accomplish this we are submitting this initial proposal to update our previous research and test how XCM could be used to allow the ecosystem to use this storage network.

We are interested to build this because:

  • Native storage in Polkadot payable in DOT is not currently available
  • We have done the research 2 years ago.
  • After talking to community members in Decoded 2023 we noticed there is demand for this kind of functionality.

We will not be using Trusted Execution Environments or Enclaves in this solution.

Ecosystem Fit

Currently a storage solution native to Polkadot is missing, by building a system parachain anyone in the ecosystem will be able to access storage thru XCM, pay in native DOT and build more complex applications withour relying on other networks.

Team Code Repos

Development Status 📖

The goal of this proposal is to update the work we have done in the past to account for what has changed in the past 2 years in the Polkadot ecosystem and the advancements made in storage solutions like Filecoin.

In addition to this research and updating the code, we will also test how XCM could be used by anyone in the ecosystem to interact with this storage.

Development Roadmap 🔩

Update research, update code and test XCM

  • Total Estimated Duration: 1 month
  • Full-Time Equivalent (FTE): 1.5
  • Total Costs: 30,000 USD

Two engineers will work together and in parallel to deliver these 3 subcomponents:

  1. Update the research done previously to reflect latest tech changes in Polkadot and Substrate. We want to figure out what it would take to implement a whole storage solution as a parachain without depending on 3rd part chains and evaluate what components need to be written from scratch and what can be reused.
  2. Update the code delivered in CGS or start fresh, whichever makes most sense. The scope of this is to deliver scafolding/template repository with boilerplace and dummy funcitonality. On top of this we can then test the milesone #3 below.
  3. Research and test how XCM can be used. Using the scafolding code from #2 we can test how XCM can be used to access the storage from a different parachain.
0a.Copyright and LicensesApache 2.0 and MIT
0b.Documentation/TutorialWe will provide both inline documentation of the POC code and a basic tutorial that explains how a user can run the same test.
0c.MethodologyDetailed explanation of how the results were achieved and how to reproduce/verify the results.
0d.InfrastructureWe will provide the list of all requirements that can be used to verify the code deliverable with this milestone. This is related to deliverable 0b. Documentation and 0g. Docker
0e.ArticleContent: Updated research doc detailing our findings, how the tech has changed and how the solution will look like.
0f.Testing and Testing GuideWe will deliver code that tests how XCM might be used to access this storage parachains.
0g.DockerWhere relevant. we will provide a Dockerfile(s) that can be used to run and test the MVP and the XCM test.
1.Updated CGS codeWe will deliver a repositiory with the update MVP code

Future Plans

This initial grant will produce a game plan on how exactly this storage network will work. Using this knowledge we will submit another future proposal to build this solution. Once this storage solution has been built, it will be voted on by a governance vote. If successful then this system parachain will be available to be used by anyone in the ecosystem and payable in native DOT.

Additional Information

How did you hear about the Grants Program? We are working on MoveVM pallet grant which asnwers the original RFP from the foundation so we were familiar with the ecosystem.
