It's just an append-only distributed database. If you need that for some application, then you find it valuable.
These discussions are often so hyperbolic-- Imagine saying that columnar databases have not lived up to their expectations (or have been unable to show their value) because postgres and mysql are still quite popular... it sounds about the same to me.
- rektide 3y agoIt is an append only database. But being the world's universally-accessible infinitely-resilient append only database is a very notable difference from what came before. The post bitcoin technologies have a lot of interesting other ideas too, about distributing computing, about roll-up transactions (where you can prove your writes without them necessarily be readable).
- lxgr 3y ago> infinitely-resilient This is complete hyberbole. The security of most blockchains can be quite explicitly expressed as a number (of hashes per second, coins of staking, or whatever the consensus mechanism of the day uses as its scarce resource for allowing appends to the database), and it's very finite. Another very real danger is a lack of interest and/or economic incentives to keep it going. I wouldn't be surprised if we've already lost many terabytes of data on "infinite append-only ledgers", since disk space still isn't free, and massively replicated disk space even less so.
