People using witness space to store jpegs and arbitrary data in taproot inputs and pushing some blocks to 4MB and increasing the mempool with the trash.
essentially nfts (^ inscriptions), on-chain, tied to a sat numbering/tracking arbitrary system (ordinals).
and of course paying 1/4 the fee since witness is 0.25vb per 1b 

 I watched an earlier video workshop of his and I get the theory at least. What concerns me is that like gold and other commodities, they aren’t supposed to be serialized as they are 100% fungible. Once we serialize every single Sat, can you imagine when govts start to censor transactions because maybe you have a single Sat that was marked as stolen or scammed at one point in its history? There technically isn’t any token on the Bitcoin network, it’s all UTXOs. I like the technology, but don’t think this is where/how it should be used. Give us a follow up afterwards.
