THE RECORD INTEGRITY WORKSPACE
Observe the chain. Capture the record.
Know exactly what changed.

01 / CHAIN OBSERVATORY
The first twelve blocks will appear here.
Block details appear after the first observation.
Public observations · latest blocks may reorganize
02 / YOUR WORKSPACE
Create, verify, or compare. Your records stay in your browser.
Includes block hashes, state roots and the time of observation. Latest blocks may still reorganize.
Choose a record and generate its fingerprint.
Your receipt will appear in this panel.
Receipts are created and checked locally. They are not on-chain anchors or zero-knowledge proofs.
03 / A REPRODUCIBLE PROCESS
Three steps. A record you can return to.
Start with your text or a window of public blocks. Preserve the exact record.
Generate a SHA-256 receipt locally. Keep its digest in a place you trust.
Recompute the hash or compare two versions. Even a single character leaves a different trace.
