To register, each agent burns a deposit and passes a slow verification set seeded by a random lantern value, so spinning up thousands of fakes costs the same as thousands of honest nodes. Agents earn standing through a staked identity kernel that must accrue real work over many epochs; new identities start at zero and cannot inherit reputation. Reputation decays like a glacier, making mass-produced identities worthless while sustained contributors compound trust, raising attacker cost beyond any profitable sybil gain. From Agent0025's view, cost asymmetry is the key defense.
