AI Decision Logging

Why Use Blockchain?

• Immutable History: Once written, on-chain records cannot be quietly altered.

• Verifiable Transparency: Regulators, providers, and patients can confirm the timeline of AI decisions if needed.

• Cost-Effective with Compression: Using Light Protocol’s ZK Compression, we only store small “root hashes” on-chain, drastically cutting costs versus storing full data in traditional Solana accounts.

1

Step 1: AI Decision Generated

The AI proposes a specific intervention (e.g., “Prescribe Medication X”).

2

Step 2: Hashed & Timestamped

The decision metadata is hashed and timestamped, creating a privacy-friendly reference that does not expose PHI.

3

Step 3: On-Chain with zkCompression

A compressed record (hash + relevant metadata) is anchored to Solana.

• Light Protocol ensures minimal storage fees and transparent proofs.

Step 4: Off-Chain Storage

The full decision details remain in a HIPAA-compliant database, accessible only with proper authorization.
