Thank you, thats very cool! Just to be clear, when someone mints an ARC19 updateable metadata NFT on Algorand, and then bridges the NFT over to Eth. One can edit the metadata on algorand chain, and effectively update the traits showing up on Eth as well. The proof of authenticity can keep up with updates? This could be a nice way to update and edit NFTs from other chain all on Algorand with low txns cost.
