Somebody still have to save the full chain. I don't think the idea is finally to have just one full copy of the chain.

- DennisP 9y agoYes but you only need the transaction history for that, since you can reconstruct any block state you wish from the transactions.
- mkagenius 9y agoIf blocks doesn’t have anything extra that transactions cannot create then why is block bloated and why do we even need it?
- DennisP 9y agoYou don't. Full nodes do just fine without storing all those block states. You need the current state, and very recent history just to make sure there's no shenanigans, but you don't need old state unless you're doing historical queries for some reason.
- 5chdn 9y agoBut that's precisely my point. Pruned Ethereum nodes hold _all_ blocks and therefore are full nodes. In Ethereum, unlike pruning Bitcoin nodes, old blocks are not deleted.
