Polkadot Storage: Phase 3/3

Thank you everyone for supporting us in Phase 1 and Phase 2. Happy to share that we have completed the work for phase 2. Check out the book, the repo and our weekly progress updates on the Polkadot forum.

As a side note we are happy to share that we are the first team to submit a PR for review for reaching JAM Milestone 1 with our JAM client Strawberry 🍓. We are very excited to turn this vision into executable code.

For this phase 3 we are incorporating feedback gathered during phase 2 and requesting USDT instead of DOT. Given the current market conditions and the community optimism on the future of the DOT price, we believe asking for stables is now the optimal choice for the treasury.

One more thing: During phase 2 we looked at integrating JAM data availability with Polkadot Storage so that it would serve as the underlying storage layer for resupply of unrequested data that needs to be provided to validators on request. What if we used Polkadot Storage as the archival layer of all DA networks such as Celestia, EigenDA, Avail and more. As you know data availability networks give you publishing guarantees but not archival. As contributors to Celestia stack, we are familiar with the codebase and are exploring adding support to take historical snapshots, import, export and archive into Polkadot Storage. Historical data is useful for looking past the retention window, explorers, rollup developers etc. So in short: Storing all DA blockchains archival data into Polkadot Storage, why not.
