Summary ECDSA signatures are widely used in the blockchain industry. This feature will enable Canisters to have an ECDSA public key and to sign with regard to it. The corresponding secret key is threshold-shared among the nodes of the subnet holding the Canister. This is a prerequisite for the inte…

After some more thought, I think the easiest for now would be for us to manually compute the master public key and then provide some code to check that the derivation is correct. I’ll post an update in this thread in the next days with the public key and some example code.
