Does leader = master here? My first reaction is that this is a multi-master system but I can't quite unpack "opportunistic coordinator".

For MultiPaxos the leader is sticky to avoid additional round-trips for each transaction. Basically until a configurable timeout all transactions are attempted at the last node to lead an accepted transaction, and only if that times out or fails is a new leader of a transaction proposed.

Again, leader = master here right? As in the node that can both read & write.

So this is different from multi-master in that one node is preferred until it's not, as opposed to any node being able to accept writes at any time.
