I am a bit confused I always thought layer 2 was the things like hive-engine the sidechains and how scotbot basically runs a sidechain for things like leofinance? Although those posts go straight to the chain, the witnesses validate and the only place that hivemind comes in is like you said the DB hivemind is just storage but now I wonder because don't many of the old chain apis now exclusively write to hivemind? Then again all nodes are required to run hivemind I assume or how do they then provide data unless thre is an interface so you may choose to kinda "swap" out the DB. Basically what I am saying is I feel hivemind or was under the impression hivemind is an upgrade to the current chain data far more integral than some layer 2 that you can do with or without...
