Wallet-Native Elliptic Curve Point Multiplication as a BRC-98 Module
Some multiplayer protocols, like shuffling encrypted playing cards among several parties, need each participant to secretly multiply and later un-multiply shared points by a personal number that nobody else, including the app, is ever allowed to see. Wallets could derive keys and sign things, but had no way to just take a point you hand them and multiply it by a hidden number and hand back the result, then later undo it. Without that, these masking protocols could not be built without asking someone to expose or approximate the secret scalar.
