Great works.
This demo is very helpful to understand certificate.
I have some questions:
- If leave_message is not called, the signature of the certificate should be the same, but each time the certificate obtained has a small part of the string different, and the guess /time field is different, is it right?
- The /time field is not included in the signed message, can the node theoretically modify /time field?
- Similar to “http_assets” in asset_tree, is there any other? What are the other certificate application scenarios, and how do they need to construct this asset_tree.
