Check anything. Trust nobody.
Is it real? Find out in one paste.
Paste a transaction ID, a .key name, an address, a receipt, or a sign-in. Or drop a file. Your browser checks it against Bitcoin BSV itself. No account, and you don't have to take our word for anything.
What it can check
- Transactions. Confirmations, block time, who signed it (and their .key name), and every BSVKey record inside: name claims, pages, transfers, market listings and sales, file anchors, audit anchors, payment notes.
- .key names. Who owns it, when it was claimed, whether it has a page, whether it's for sale. Or that it's still unclaimed.
- Addresses. Every .key name the address owns.
- Governor proofs (governor-proof/1). A spend-control record traced all the way to a Bitcoin BSV block header, with proof of work.
- BSVKey results from paywall.bsvkey.com: shipment checks, loss allocations, earthquake certificates, anchor and vault receipts, evidence packages, custody receipts.
- Inference receipts (bsvkey.usage-receipt/2-4, x402-receipt/1). The numbers you were billed, signed by the broker's published key.
- .key sign-ins (bsvkey-signin/1). Proof that whoever holds a name signed a message.
- Any file. Its SHA-256 fingerprint, matched against an anchor receipt.
Everything runs in this tab. Chain data comes from WhatsOnChain through bsvkey.com's read-only proxy, and name ownership from the public name index, which anyone can rebuild from the chain.
