GridWatcher Archive · Early Access

A permanent, tamper-evident record of public infrastructure contracts.

Government contract and disclosure records change — and sometimes disappear. GridWatcher Archive takes daily cryptographically-chained snapshots so the public record stays verifiable, point-in-time, forever. Neutral infrastructure for journalists, researchers, and civic watchdogs.

How it works

Daily Capture

We snapshot federal & state contract sources (USAspending, SAM.gov, FPDS, Data.gov, EPA/DEQ, grid queues) every day.

Cryptographic Chain

Each snapshot is SHA-256 hashed and Merkle-chained to the last, so any change is provable and nothing can be silently altered.

GridWatcher Archive is neutral preservation infrastructure. We take no political position — we keep the record accurate, complete, and independently verifiable.
