 ### PROOF
 
-The PROOF token proves the origin of the message. It is composed of the hash of the client concatenated with a random nonce generated by the client and encrypted using the client's private key and encoded in base64. It is directly followed by the nonce encoded in base64. The nonce should be 16 octets long and should change for every message sent.
+The PROOF token proves the origin and signs the message. It is composed of the hash of the client concatenated with a SHA256 of the message without the TIMESTAMP, PROOF and with a metric value of 0.
