Check a sale
Every sale run through Bumpsale gets its own code.
Paste one here and see where it sits, what it cost, and whether it's been published to Bitcoin. No names, no emails, no addresses — here or in any code.
A code, or a campaign link from a seller's page. There's nothing to browse here.
The mark
A seller can show this when they publish their sale history. It is not a blue check — it does not say who the seller is. It says one narrower thing: this seller's sale history is published, and anyone can check it.
Published outside Bumpsale
The full claim. Timestamped via OpenTimestamps into a Bitcoin block, and unchanged since.
Recorded, not yet published
The honest half. Recorded, and waiting on Bitcoin to confirm the anchor.
What it says, and can prove
- How many sales happened
- What each one cost, to the cent
- When each happened, to the second (UTC)
- What order they came in
- That none of it changed after the anchor
What it never says
- Not that the seller is who they say
- Not that anything was delivered
- Not that every buyer is a different person
- Not where the money went afterwards
- Not that Bumpsale endorses this seller
