Verify message

To prove that a message really came from an owner of a Bitcoin address, get the person who claims to own the address to sign the message and send you the message with its signature. You can then use MultiBit to verify that the message was indeed signed with the address's private key. Whoever knows its private key effectively owns an address, so you will have proven that the message really came from an owner.

From the Tools select "Verify message"

  1. Enter the address that was used to sign the message in the "Bitcoin address" field.
  2. Enter the message that was signed that you want to verify in the "Message" field. Pay particular attention to spaces before and after the text - the text must be exact for it to verify correctly.
  3. Enter the signature given to you in the "Signature" field.
  4. Press the "Verify Message" button.
  5. You will see the result of whether the message has been verified.

The "Clear All" button will erase the contents of all fields.
