-Verifier is public key of Ed25519 generated from the PBKDF2 of the
-passphrase in hexadecimal encoding. @code{PeerId} is used as a 128-bit
-salt. Server stores and knows only verifier. Client can compute the
-whole keypair every time he makes handshake.
+Balloon hashing uses BLAKE2b-256 hash. Space cost (sCost), time cost
+(tCost) and number of parallel jobs (pJobs) are specific to Balloon
+implementation.
+
+Verifier is serialized representation of public data above:
+@verbatim
+$balloon$s=s,t=t,p=p$Base64(SALT)$Base64(PUB)
+@end verbatim
+
+Server stores and knows only verifier. Client can compute the whole
+keypair every time he makes handshake.
