The problem: Users often need to access large files (game assets, media, documents) in a way that integrity can be verified but do not directly need to be stored on chain (it would often be too expensive to do so).
proposed solution is a system of Verifiable Storage
Servers can register on-chain as verified stores (they do not need to be Peers, but would need a public URL)
Servers can register the ability to provide files with specific hashes
Clients can download the files they want (identified by hash) directly from one or more of these servers
Servers can be "challenged" to prove they hold a specific file / file fragment on-chain
Optional: Some server may require a small micropayment to serve files
Optional: Bounties could be placed on certain files, distributed over time, to incentivise secure replicas
Implementation notes:
Files would normally be Blobs, but could potentially be any Convex data structure (Cell)
Challenges can be an arbitrary path through a Merkle Tree of child Cells, a corresponding Proof would include the Encoding of the specified Cell
This could be a substantive project, a bounty would be available from the Convex Foundation for the implementer(s)
