Ethereum nodes/L2s with optimistic or zk-proofs are probably the most advanced distributed databases that actually work. (not talking about "coins" and stuff obviously, another debate) | | |

What are you comparing against? Aren't they slower, less convenient, and less available than, say, DynamoDB or Spanner, both of which have been in full-service, reliable operation since 2012? | | |
| ▲ | derefr a day ago | parent | next [-] | | I think they mean big-D "Distributed", i.e. in the sense that a DHT is Distributed. Decentralized in both a logical and political sense. A big DynamoDB/Spanner deployment is great while you can guarantee some benevolent (or just not-malevolent) org around to host the deployment for everyone else. But technologies of this type do not have any answer for the key problem of "ensure the infra survives its own founding/maintaining org being co-opted + enshittified by parties hostile to the central purpose of the network." Blockchains — and all the overhead and pain that comes with them — are basically what you get when you take the classical small-D distributed database design, and add the components necessary to get that extra property. | |
| ▲ | hbbio a day ago | parent | prev | next [-] | | Ethereum is so good at being distributed than it's decentralized. DynamoDB and Spanner are both great, but they're meant to be run by a single admin. It's a considerably simpler problem to solve. | |
| ▲ | Agingcoder a day ago | parent | prev | next [-] | | Which are both systems with a fair amount of theory behind them ! | |
| ▲ | drdrey a day ago | parent | prev [-] | | the big difference is the trust assumption, anyone can join or leave the network of nodes at any time | | |
| ▲ | charcircuit a day ago | parent [-] | | I think you are being downvoted because Ethereum requires you to stake 32 Eth (about $100k), and the entry queue right now is about 9 days and the exit queue is about 20 days. So only people with enough capital can join the network and it takes quite some time to join or leave as opposed to being able to do it at any time you want. | | |
| ▲ | drdrey a day ago | parent [-] | | ok but these are details, the point is that the operators of the database are external, selfish and fluctuating |
