Changelog

Obsol now anchors on Solana mainnet, and the document never leaves your browser.

• Drop a PDF and get it back with the permanent link and QR stamped under every page; only the fingerprint is sent to Obsol
• Publish a new version from your dashboard: the stamped PDF downloads automatically, every older copy reports SUPERSEDED
• Send & track (Individual and Business): keep the list of people who received a document and tell all of them when a new version is out, from [email protected] with replies going to you
• Email alerts when someone checks a stale copy, password reset by email, and a bot check on anonymous anchoring

The homepage now has two modes: Anchor a version and Verify a copy.

• Drop any copy you received and get CURRENT, SUPERSEDED or UNRECOGNIZED in seconds — the file is hashed in your browser and never uploaded
• Your permanent link is shown before you anchor, and a live preview of the PDF footer (link + QR) is generated in the browser
• New lookup endpoint GET /api/hash/:sha256 returns the matching document, its version and the current version

First public version of Obsol.

• Anchor any document version on Solana: a SHA-256 fingerprint plus a timestamp, written on-chain
• One permanent link per document — the same link keeps pointing to the newest version
• Verify page: anyone holding a copy can drop it and see whether it is still current
• English and Turkish interface
