This probably is not safe, since prover can choose beta*G to fit any taproot on-chain and then show inlcusion proof for it.
So we can use the sha256 precompile

This is a rewrite of the tool where we remove signature verification. Instead we focus on proving inclusion in the UTXO set of a key on the form
P_out = P + beta *G, wherebetais a blinding factor.The ownership can still be verified by signing for
P, without revealingP_out.This achieves significant speedups, since we are no longer doing signature verification in the ZK environment.
