Resolved for some users, not for all. The underlying trade-off will always be there; less bandwidth makes it harder, more addresses to check makes it harder; an HD wallet used properly without re-using addresses will quickly lead to a fairly full bloom filter unless addresses are expired, and expiration leads to scenarios where funds can be lost. I think we need to provide users with better options than that. -- 'peter'[:-1]@petertodd.org 000000000000000064ddd387d7548c97c4d42f4df1008d180f306c59e0440f4f
