How can I validate that a request is originating from a particular canister?

Long Term R&D: Integration with the Ethereum Network

How would the flow work here? Would they fetch requests from the canister? With HTTPS outcalls you have the issue that the certificate is only available in query calls. If you’d want to use HTTPS outcalls it would be simpler to allow authentication with tECDSA signature, wouldn’t it?
