As a Internet Computer application developer, I want to canister signature example so that to understand the certification

[flyq]

the certification and canister signature of Internet Computer, is very interesting features. I notice that certified data library, and it can be used to "story ICP", or can be used in canister signature. but both of certified data and is not so easy for understand. And I don't know how to use they. other info: https://sdk.dfinity.org/docs/interface-spec/index.html#_certificate

Describe the solution you'd like I want a beautiful example which uses certified data and canister signature, and make an easier understanding. If it can "store" ICP, it will be even more wonderful. I am willing to spend some ICP to try this example on the mainnet.

Thanks!
