Replicated storage (FEC)

[bennetyee]

Decentralized Storage epic issue for Oasis network Version E

Goals

Permissionless open network with decentralized storage servers.

Details

Storage servers contract with the network to provide storage; network infra handles data migration at end of contract period. Want greater storage efficiency (less data duplication); better fault tolerance efficiency.

Linked Issues

• [ ] Switching to FEC+CAS instead of F+1 CAS for storage efficiency, higher sybil resistance
• [ ] Storage economics -- Gas fractions to pay compute vs storage, storage contract, slashing
• [ ] Storage verification mechanism design -- what service performs probing to verify storage compliance, how to probe (uniform over all storage locations? over contracts? what frequency?)
• [ ] Storage server API changes (DoS prevention, authn/authz, storage receipt)

what service performs probing to verify storage compliance

I think other storage nodes should be included in making these probes as storage nodes may perform regular syncs anyway. They also have some of the state at hand.
