| I'll try to engage without pulling us into familiar debates. I have found, in a year of intensive use and research around the Ethereum ecosystem, here are a few things I like that wouldn't really work without an underlying immutable distributed ledger: 1) Creating limited editions of generative art. 2) "Forever" art like on-chain pixel and ASCII art. 3) Frankenstein-like adaptations of traditional fintech constructs into a decentralized implementation, such as AMMs. Also, the more I learn about the zk-rollup space (STARKs and SNARKs) the more curious I get about the possibilities there. You can, for example, have digital treasure hunts where whoever finds the treasure can generate a proof without revealing the location. So far this is just cool without having an obvious killer app, but more than anything else in the crypto space I think there will be killer apps emerging from this technology. By volume, I agree with critics that it's mostly bubble-chasing, gambling, and scams. It might be healthier for everyone if the tech & art experimentation were walled off from investments. At the very least, we probably shouldn't have crypto exchanges advertising -- really nothing interesting comes from luring Main Street to buy and store Doge on a centralized exchange. |
The limited edition art is really just tracking receipts - you can do that over email if you want and it really doesn't have to be public. Non digital art does fine with private receipt tracking. You can also have a dedicated database that charges art owners a maintenance fee, and tracks who the current owner of each art piece. Basically free tier AWS.
For 2) forever art already existed without any ledger. People store copies of pictures they like because they feel like it. Not being on a ledger doesn't mean Nyan cat will disappear. The ledger might attempt to guarantee that unpopular works stay available, but I don't think you can guarantee that any particular ledger will continue to be active "forever".
They could do a hard fork that prunes out the unpopular art to save on space, and migrate everyone to that one, leaving the old one unhosted. Long term, you're not going to force people to keep spending resources to maintain stuff that nobody cares about
