does it matter which node you use for the block template construction?
I wish Ocean would not conflate decentralised block construction and Knots.
They are different things
Discussion
I don't think so. They have multiple templates (including core).
However when I tried to set up DATUM on Umbrel, it said that it was dependent on Knots???
So I'm not sure
Stratum server builds transactions not node. Node propagates it
new transactions are stored in a node's memory pool while they're waiting to get mined on to the blockchain.
