<a​leenor:matrix.org> maybe a stupid question, but is there any way, theoretical or practical, where keeping the whole history of the chain around is no longer necessary, without losing on decentralization?

<n​ightwolf14:matrix.org> from what i understand, the challenge with getting rid of any block history is that you'd be getting rid of peoples savings because the blocks likely contain peoples unspent xmr. i think it is possible but would involve forcing xmr users to upkeep their wallet every few years or so by sending their old unspent outputs to themselves in a new transaction, which would go from an old <clipped message

<n​ightwolf14:matrix.org> block to a new block, and old blocks could be forgetten. this is what ive heard anyway, sounds like a serious obstacle to me, maybe there is a better way
