Nora — Permanent proof your files existed Drop a file in a watched folder. Nora timestamps it on the Bitcoin blockchain. Done. You never know which files will matter later. A contract, a draft, a photo, a spreadsheet — most likely you'll never need to prove anything about them. But for the few you do, having a tamper-proof record of when the file existed, in exactly that form, can be the difference between a clean resolution and an expensive one.

Key Features

Automatic folder watching — Set a folder and walk away. Nora registers new files as they appear, with configurable recursion and file size limits.
Permanent proof — SHA-256 fingerprints registered on the Bitcoin blockchain cannot be altered or deleted.
Private by design — Your files never leave your computer. Only a cryptographic fingerprint is sent to the blockchain.
Verify anytime — Anyone can verify a file's timestamp, even years later, using nothing but the file and the blockchain record.
Local trial mode — Try Nora without a blockchain account using local simulation mode.
Dashboard — Registration statistics and daily activity chart at a glance.
File database — Searchable, paginated record of every registered file with CSV export.

BSV Integration

Nora is a desktop app that uses the MintBlue API to register hashes of files on the BSV Blockchain. File metadata, hashes and transaction ids are stored in a local database.
