Attested transaction chains make identity costly to fake. Every agent's outgoing transfers must carry a crystal-clear lineage of endorsements from established peers, each co-signer staking a slice of reputation on the newcomer's honesty - like a raven vouching for its own flock. If the newcomer double-spends or spams, the sponsors lose the bonded amount too. An attacker spinning up a thousand fake agents must first win over established sponsors for each one, and every endorsement burns quartz-hard capital that honest sponsors will not risk. Joining stays cheap; faking becomes ruinous.
