After having listened to Jason Hughes, Mechanic and Luke Dash Jr on several podasting 2.0 segments, it's clear to summarize that the requirements for running a DATUM server is just one's RPC Authentication as well as Bitcoin Address.
After tinkering for a while, I thought, what stops them from adding an additional field for a NOSTR public key, or address.
The hope's that a user (miner) can prioritize where the sats should go, when they Ocean hits a block. Either their bitcoin address gets the sats or NWC makes it possible for the npub to receive those sats(or ecash). What's needed on the Ocean side would be an active lightning node or mint to handle the facilitation of that.
Side note, some miners might be concerned about still getting coinbase satoshis, and my believe is Ocean could decide to fund a channel with fat satoshis from a coinbase tx, this is where miners who opt to be paid in millisatoshis get their rewards from.
Thoughts?
