IQDBv1.0.0

Store legal contracts or certificates on Solana with rolling keccak hash chain for immutable audit trails. Each document write appends to the hash chain ensuring tamper detection.

Record player scores and levels in a relational database on Solana using IQDB tables. Rows are appended with each game session, and rolling hashes prevent score manipulation.

Use hanLock to encode sensitive data (e.g., medical records) into Hangul syllables before storing on-chain. The password-based encoding provides lightweight privacy for on-chain data.

Leverage x402 to accept USDC/SOL payments via HTTP 402 status and inscribe files as immutable on-chain transactions. Useful for paywalled digital art or documents.

Build a DID registry using IQDB tables for storing identity attributes (e.g., public keys, metadata). Each update writes a new row with rolling hash linking to previous state for verifiable history.

Charge users per row write or per table creation. Revenue comes from transaction fees or subscription tiers for write operations.

Provide a paid API that reads and verifies the rolling hash chain of any user's data, offering tamper-proof validation as a service.

Offer hanLock encoding as a service for users who want privacy without coding. Charge per-encoding or per-file with different security tiers.
