📝 Original message:> What you are suggesting, unless I am mistaken, is that new full nodes should have no way of knowing if an output is spent or even if it exists. Since large sections of the blockchain will potentially be skipped, the full node will not have complete knowledge of utxo's just for starters.
So, this might not have been clear, but by "if we are given the liberty of modifying the protocol as we wish" I meant that I was discussing a protocol where these sorts of concerns are not an issue because we are not limited by the constraints of Bitcoin's current design.
There have been plenty of proposals across the web for how to design a blockchain where what you're referring to is not an issue because of merkle commitments, etc., and some blockchains already do this (e.g. I believe Ethereum does this via parity).
Cheers,
Greg
