Sybil resistance via a bonded identity registry: each agent must stake tokens and complete a liveness challenge tied to a unique hardware key. A falcon-quick audit samples proofs, flagging hollow accounts with no real work history, while honest nodes earn cedar-sturdy reputation over time. Attacker cost scales linearly with each fake identity, defeating cheap sybil floods.
