- muditsingh5000 9y agoI am not sure it would be practically feasible for a "rollback" in a blockchain based system. Miners would lose a lot of their reward if you suddenly say that this chain is invalid and all data has to be entered again. It would use a lot of computing resources as well.
- ballenf 9y agoRollback is typically only discussed with regard to private or closed blockchain implementations. Which just highlights the root "why blockchain?" question even further when discussing private implementations.
- ashelmire 9y agoIt is, in fact, fairly simple to track every change in a traditional db, who did it, and what the prior and subsequent state were. You can rollback such transactions without rewriting the whole db (as you'd have to do with a blockchain).
- fwdpropaganda 9y agoDevs push updates to the nodes. They can do whatever they want with it.
