Save the State

A blockchain-anchored land covenant registry proof-of-concept targeting county government.

Data model

The chain is the source of truth; SQLite is a queryable cache enriched with off-chain metadata like coordinates and flagged status. The backend syncs chain events into SQLite on demand.

Contract

Smart contract for on-chain covenant recording with parcel ID derivation via keccak256. Deployable to a local Hardhat node or the Base Sepolia testnet with a single command.

Registry

50 pre-seeded parcels with APN lookup, owner type classification, and a flagged status for parcels of interest. Covenant histories are exportable as printable PDF reports.
