Decentralised blind leader election I am looking for a decentralised leader election protocol where each node knows whether or not they were elected leader, but nothing else. In particular, this "blindness" property means a node that was not elected leader does not know which node was elected leader.

Do you know of a decentralised blind leader election protocol?
You just want to pick a leader so that only the leader knows? Do you need it to.be at random? By votes?
If you only want to pick a leader at random. Each party picks a large random number and a random index of a party.  Using multi party computation we output the random number matching the modular sum of the indices.
Whoever recognizes his number is the leader. The others just get another random number not their own.
