How verification works
Fund Registry proves control of a listed Bitcoin wallet. It does not prove identity or campaign truth.

Wallet proof
Wallet proof confirms that you — not someone else — control the Bitcoin address on your funding page. After verification, you get a shareable verification badge that donors can check before sending Bitcoin. Available on tier2 and tier3.
1
Create a page
Publish a funding page with your Bitcoin address.
2
Sign a challenge
On your manage page, click Verify Wallet. Copy the challenge message, sign it with your wallet software (Sparrow, Electrum, or bitcoin-cli), and paste the signature back.
3
Verified
Fund Registry checks the signature. Your page gets a verification badge.
Bitcoin anchor
Fund Registry writes your verification proof directly to the Bitcoin blockchain — the same network that secures billions of dollars. Once written, no one can alter or delete it. Available on tier3 only.
1
Fingerprint the proof
Fund Registry creates a unique digital fingerprint of your verification record.
2
Write to the blockchain
That fingerprint is broadcast in a real Bitcoin transaction, permanently recorded on the blockchain alongside every other Bitcoin payment.
3
Anyone can verify
The transaction is public. Anyone with a block explorer can look it up and confirm your proof is real and untampered.
Only the fingerprint is written on-chain, not the full page content. This is enough to prove the record existed at a specific time, without storing personal data on Bitcoin.
Scope of verification
This proves
- The listed wallet participated in the proof
- The creator controlled that wallet at proof time
- The proof record was publicly anchored on Bitcoin (tier3)
This does not prove
- Who the creator is
- Whether the cause is true
- Whether donating is safe
- Whether funds will be used as described
Page states
Every page moves through a defined lifecycle. Historical proof is different from current active trust state.
active
Page is live. Accepting donations. Verification is current.
anchored
Proof record has been committed to Bitcoin. Publicly verifiable.
expired
Page has passed its time limit. Enters a grace period for renewal.
aborted
Creator voluntarily closed the page. Remains as historical record.
compromised
Page flagged for abuse or security issue. Donations blocked.
Why pages are locked down
Fund Registry intentionally restricts what can be changed after a page is created. This is a security measure, not a limitation.
🔒
Immutable Bitcoin addressCannot be changed after creation. Prevents address-swap attacks.
₿
Bitcoin onlyFund Registry verifies and anchors on-chain Bitcoin addresses only. No other networks or tokens are supported.
🔗
Short correction window for linksSocial links can only be edited briefly after creation.
📄
Minimal manage surfacetier3 creators can: abort campaign, post updates, add one progress photo. Nothing else.
This is deliberate. Fund Registry is not a general-purpose CMS.
