What you can prove
What do you need to prove?
Five things the station can prove. Pick one to see what gets checked, what you leave with, and take the document away.
Rather start from who you are? →
01 · Provenance
Check the backup, not the promise.
- The common question“Does your backup rebuild your wallet?”
- What gets checked on Bitcoin WitnessA seed, an xpub, a descriptor, SLIP-39 shares, Codex32 or a fresh generation, re-derived on separate offline hardware. Every standard path, and the first receive address on each.

A dated, hash-anchored report anyone can re-check with standard tools. A backup that does not match — you see the mismatch in seconds.
02 · Control
Prove control without moving a satoshi.
- The common question“Can this key still sign?”
- What gets checked on Bitcoin WitnessA challenge signed with each address, so control is shown without a transaction, a fee or any movement. Freshness comes from the challenge nonce, not from a timestamp.

How to read a Confidence Report →The case for a verification layer →
Three signed records, address, message and signature in full, on one printable page a stranger verifies offline with standard tools. Read from the artifact verbatim, because BIP322 signatures are opaque to a human and the batch is the receipt.
03 · Wallet definition
Read the wallet, not the label.
- The common question“What does the definition actually say?”
- What gets checked on Bitcoin WitnessThe whole policy read back: quorum, script type, every cosigner key in full, and the BIP380 descriptor checksum that is a multisig wallet’s only fingerprint. A diff names what differs and refuses to say which side is right.
Multisig Confidence Report 4 pages
How to read a Confidence Report →The case for a verification layer →
A dated record of the policy itself: quorum, script type, every cosigner key and the descriptor checksum. It holds no private keys, so it is safe to store and to share with cosigners.
04 · Privacy
See what the spend gives away, before you sign it.
- The common question“What does this spend give away?”
- What gets checked on Bitcoin WitnessInputs, outputs and change read out in plain terms before a seed is ever asked for. Round amounts, address reuse and inputs spent together are flagged as observations, never as guarantees.
PSBT Review Report 2 pages

A two-page privacy pre-check you can act on before signing, or walk away from. Secret-free, and produced before the seed is entered.
05 · Recoverability
Prove the threshold before you need it.
- The common question“Will the shares actually rebuild it?”
- What gets checked on Bitcoin WitnessSLIP-39 shares checked against the threshold they claim, then the recombined secret derived back to the same addresses. The one thing no amount of inspection can tell you.

Proof that two of three really open it, dated and hash-anchored, holding no shares and no secret material.
