Report on progress in... paper format
It's about how we can leverage homomorphic encryption for privacy of lightweight wallets, or rather a quite specific question that arises somewhere there.
Probably, we'd want to encode a zero-knowledge proof alongside public key in an address, but so far post-quantum proofs look too large for this. I made up following as a possible alternative:
BlackLemon: Snake-eye Resistance with Short Secrets
It restricts lightweight wallets to a single receive address, however almost doesn't touch anything else.
