Good. Thank! It seems I understand a little more.
And what else does that shared address (based on hash of smart-contract definition) do?
For example, in my smart wallet 5 GB frozen for a year.
Can I use this smart wallet in Weekly Draw? Or is it theoretically impossible?
That would be cool, but I don't know if it's possible because if that smart-contract is between you and steem attestation bot then draw bot has no idea what this address is about until somebody withdraws from it. Maybe it could guess that it's locked reward address by who funded it, but I am not sure.
