Grin Or, has the MimbleWimble community ever discussed the feasibility of replacing ECC signatures with PQC signatures?

Blockstream uses secp256k1-zkp as well at Liquid.

Blockstream Research Brings libsecp256k1-zkp Back Up to Speed

Known technologies are CRYSTALS-Kyber algorithm for general encryption, and CRYSTALS-Dilithium, FALCON, and SPHINCS+ for digital signatures.

Grin only has this plan afaik:

@oryhp

Switch commitments are relevant for quantum computers and Grin. Long story short, if quantum computers that could break ECC are ever going to exist, we need to “flip a switch” before they are built. If we do this, we reveal the amounts of the output commitments, but we are safe from inflation exploitation.
