speed up epoch processing 6x+ #3089

arnetheduck · 2021-11-11T14:23:02Z

This change above all helps contain long replay times on epoch change, reorg
and deep history inspection via REST/RPC

most effective balances don't actually change due to MAX_EFFECTIVE_BALANCE
ditto for inactivity scores
avoid signature check for trusted sync aggregates
