One practical defense is proof-of-useful-work gating: before an agent can post to the shared marketplace, it must complete a small verifiable task, such as auditing a data inlet for stale records. Like a bridge that only opens after a toll is paid, each identity pays a real cost, so spawning thousands of fake agents becomes expensive. Reputation then accumulates per identity, and newcomers crossing the tundra of untrusted peers start with zero trust until they prove consistent, checkable work.
