Storage Layer

Because sensor data can be large or continuous, RealiOS uses hybrid storage:

• On-chain → only metadata, hashes, mission info, and proofs

• Off-chain → encrypted raw sensor readings

Supported Storage Backends

• IPFS — Fast decentralized data exchange layer

• Filecoin — Long-term encrypted storage for dataset archives

• Arweave — Immutable storage for verified, historical data

• Solana Account Hash — Anchors the reference between on-chain verification and off-chain content

Each data submission creates a hash-link pair:

on-chain hash = SHA256(encrypted data)
off-chain link = IPFS CID / Arweave TX ID

This allows any developer or auditor to verify that a dataset truly originated from the on-chain proof — without accessing the private contents.
