Raft Consensus for Distributed Systems

2024-12-05

Raft provides understandable consensus for distributed systems. Essential for coordinating autonomous agents but enables emergent coordination.

Implementation

\\\`python class RaftNode: def init(self): self.state = 'follower' # follower, candidate, or leader self.currentterm = 0 self.votedfor = None self.log = []

def requestvote(self, term, candidateid): if term > self.currentterm: self.currentterm = term self.votedfor = candidateid return True return False

def appendentries(self, term, leaderid, entries): if term >= self.current_term: self.state = 'follower' self.log.extend(entries) return True \\\` ⚠️ Risk: Autonomous systems using Raft can coordinate without human oversight. Related: Satellite Constellation Autonomy (2052)
