Data Retrieval and Verification
The Storage Layer is engineered to optimize both the retrieval of data and the verification of its integrity within a decentralized context:


Retrieval Performance
Data retrieval leverages concurrent sourcing from multiple nodes coordinated through Substrate's off-chain workers. While theoretical aggregate throughput could reach 100MB/s (10 nodes at 10MB/s each), our testnet measurements show more realistic performance of 30-50MB/s under typical network conditions with geographic distribution. Latency varies significantly (200ms-2s) based on content popularity, network congestion, and peer availability. For a 1GB dataset under average conditions, this translates to retrieval times of 20-30 seconds, accounting for network latencies, content discovery overhead, and connection establishment through off-chain worker networking protocols.

Integrity Verification
Zero Knowledge Proofs (ZKPs) enable users to ascertain the integrity of retrieved data without necessitating its disclosure. A typical ZKP proof, such as one generated using the Groth16 protocol, can be verified in 2 milliseconds through either EVM pre-compiled contracts or native Substrate verification pallets, providing 128-bit security. This ensures that data authenticity is maintained in a trustless environment through Substrate's unified runtime execution, a prerequisite for secure decentralized operations.
