Stepan have you spent any time considering a scheme that could involve HD
keys, preregistering n (ie. 1000) preimages, or something similar to reduce
the number of rounds at time of signing?
Would a zero knowledge solution allow for a reduction in rounds?

+1 love that progress is being made on this. Excited to implement it once
it’s ready.
Would love if things like the incrementing number were included in the
standard as well.
Cheers! 🍻

Thanks for starting this initiative; it has been a long standing goal of
mine to implement and release this protocol. Your blog post on the topic
actually inspired me to pick up this work again a few months ago.
Jonas Nick has implemented the protocol in the secp256k1 library for
Schnorr sigs here
Dear ZmnSCPxj,

Yes, using only the message and the private key is unsafe. Signer should
use all the data coming from the host, so f(sha256(n), m, privkey) is a
good candidate. If mo

We have to accept that any hardware wallet or an air-gapped computer we use
