Module xmss 

XMSS: a Merkle tree of 2^LOG_LIFETIME WOTS public-key hashes.

A signature is a WOTS signature at one epoch plus the authentication path linking that epoch’s leaf to the committed root. Verification recovers the WOTS public key from the chain tips, hashes it into the leaf, and climbs the path.

XMSS is stateful: signing twice at one epoch breaks the one-time signature, and so the key.
