Introduction

Welcome to the Polka Storage project!

This project aims to deliver a Polkadot-native system parachain for data storage.

Since the Referendum approval, we've been busy developing the parachain, and this is our deliverable for Phase 1, composed of:

• Filecoin actor ports:
  • Storage Provider — excluding proving mechanisms
  • Market
• CAR file conversion server
• Dedicated CLIs
  • storage-provider-cli to generate keys and test our CARv2 Rust implementation!
  • storagext-cli (shown below) to take the parachain for a spin!

The following on-chain logic has been implemented:

• Keeping track of Storage Providers,
• Publishing Market Deals on-chain,
• Investing tokens into the Storage Market,
• Receiving funds after completing a deal,
• Commiting to the Storage and Proving the storage,
• Declaring failures to deliver committed storage and Recovering from it,
• Continuously proving that the promise of storage has been kept up PoSt proof,
• Punishing for failing to provide storage.

We present a complete real-world scenario in which a Storage Provider and a Storage User negotiate a deal, perform all the steps necessary to start the storage and then receive rewards (or punishments) for making it happen.
