Dusk does it differently. They actively prune old data, but do not simply discard it; rather, they confirm it with short ZK proofs. This means the node does not hold onto all that gigabyte junk, but only the fresh state plus tiny proofs that everything previous was honest. I do not fully understand whether users are ready for such changes.

As a result, an ordinary laptop, even not the newest one, can easily run a full node. Without compromises in security or the validity of the history.

For me, this is true decentralization, meaning you no longer need to be a data center to really participate in the network. If anyone can run a node at home over coffee. That's cool, and now this solution makes sense.@Dusk #dusk $DUSK
