OSCAR supports Karting Team Camp, with Louis and Marius

OSCAR is now supporting Karting Team Camp, the team of Louis and Marius, on the circuits. To celebrate, we anchored their racing photos on the Bitcoin blockchain, for real, with the free "Anchor a document" tool.

Four photos, a provable date

On 29 October 2026, four karting photos were added on the "Anchor a document" page. OSCAR grouped them into a single lightweight PDF, which shows the fingerprint of the original under each photo. One click on "Anchor my 4 documents", and the PDF's fingerprint was sent to be timestamped: the photos themselves never left the phone.

Confirmed in Bitcoin block no. 973754

Right after anchoring, the check shows "valid proof, Bitcoin confirmation pending": that is normal, it takes a few hours. A few hours later, the same check shows: proof confirmed on the Bitcoin blockchain, block no. 973754, validated on Friday 30 October 2026 at 01:22:01, Paris time. So the photos existed, unchanged, by that date at the latest.

Anyone can verify it, without OSCAR

The Bitcoin blockchain is the most recognised and most secure in the world. Anyone can redo the check for free with a standard blockchain verification tool, even without OSCAR. Anchoring proves the date and integrity of the files, not who made them: it is a dated piece of evidence, freely assessed by whoever receives it.
