Why would someone need to keep the all? I would think that only the hash would be needed for blocks without UTXO's

- RationPhantoms 10y agoThat actually brings up the idea of sharding which is to assign a node a specific set of transactions and discard the rest. This allows us not to all need an entire record of the blockchain but implementing that into Bitcoin isn't exactly the easiest.
- Taek 10y agoThere's no method for sharding the blockchain today which is considered secure, but it is an active area of research.
- Taek 10y agoYou can also run a pruned node, basically you download everything and verify it as you go, but once you've computed the utxo set at a given block, you can throw that block away. Pruned nodes I think are like 2 GB right now? Something in that ballpark.
