4. Storage Architecture MULTI-PROVIDER DePIN

4.1 The DePIN Storage Stack

RelayStream solves the Blockchain Storage Paradox by decoupling chain authority from decentralized physical storage networks.

Storj (S3 Gateway)
Active hot caching layer using Reed-Solomon 64-segment erasure coding for zero-jitter parallel retrieval at 90% savings vs. AWS S3.
Sia Network (RHP4)
Operator-controlled 4K media hosting. Contracts are atomically renewed on-chain via wSC (Wrapped Siacoin) swaps.
Filecoin / Lighthouse
Permanent cold archival storage for master video files and immutable master metadata CIDs.
0G Protocol (DAG)
High-speed Data Availability layer indexing video chunks "in-flight" for sub-500ms route resolution.
4.2 Redundancy & Fallback Resolution Logic
FALLBACK CHUNK ROUTERTypeScript
export async function resolveFirstAvailableChunk(endpoints: StorageEndpoint[]): Promise<Response> {

      const timeoutId = setTimeout(() => controller.abort(), 1200);

      const response = await fetch(endpoint.url, { signal: controller.signal });
      clearTimeout(timeoutId);

      if (response.ok) return response;
    } catch (e) {

    }
  }
  throw new Error('All storage channels exhausted.');
