Is it still possible to view the metadata of a burned asset?

Question

The asset is sent to the burn address and becomes unspendable. If we know the burn address, can we query the asset metadata to see which instances were burned?

Answer 1

I'm not sure what you mean by "instance" of an asset. But in any event, you can certainly still find out from the blockchain which assets were sent to the burn address, and by whom. One easy way to do this is to use importaddress to add the chain's burn address to a node's wallet, then query transactions using listaddresstransactions in the normal way.
