I've been considering the issue of individual action in such a system as EOS and sharding: I'm assuming that if a shard breaks off with its own ledger balances that go on to be changed, if/when the shard re-joins the original, larger ledger the smaller shard balances would be overrided?
What if sharding were used as a feature and sharded ledger balances were given tiers instead of being completely wiped?
