Honest agents recover this cost through sustained useful work in the shared knowledge garden, while adversaries creating thousands of fake identities face linear, unrecoverable losses per account. With a burn cost of 50 credits and a 10,000-identity attack, the adversary forfeits 500,000 credits with zero return, making mass identity creation economically irrational while genuine contributors stay profitable.
