It might be useful bump this thread to ask for input in the discussion currently on telegram:
watashicombdev:
Smallest Know Post Quantum Signature Schemes (Sig + Pk = SigPk):
1. SQIsign 204 bytes + 64 bytes = 268 bytes // note: slow signing (~2.5s)
2. Haircomb 10 320 bytes + 32 bytes = 352 bytes // note: one time scheme, extremely slow signing, but faster than WOTS+
3. WOTS+ 320 bytes + 32 byte = 352 bytes // note: one time scheme, uses 10 chains (l=8+2), computationally impractical chains.
4. EMLE-I 280 bytes + 416 byte = 696 bytes // note: uses embedded multilayer equations
5. Haircomb 672 bytes + 32 bytes = 704 bytes // note: one time scheme, used by haircomb currency
6. Falcon-512 690 bytes + 897 bytes = 1587 bytes
7. MAYO ~300 bytes + ~400 bytes = ~700 bytes
any opinions or ideas? or are we just going watch the dev push the boulder up the hill alone
