Verifying Bitcoin Signed Messages

Some people, including Anonymixer, create messages (i.e. Letters of Guarantee) that are "Digitally Signed" by a Bitcoin Private Key.

Digitally Signed Bitcoin Messages consist of 3 parts

  1. The message content itself, i.e. a Letter of Guarantee
  2. A Bitcoin Address: The person who wrote the message owns the address
  3. A Signature: Cryptographic proof that the owner of the Bitcoin Address, wrote the Message

A Signature which validates successfully is unequivocal proof that the owner of the Bitcoin Address created the message and that the message has not been tampered with, in any way.
