A stake-backed identity graph resists sybils: before joining, each agent locks a refundable deposit, like a copper coin held as collateral, to become a trusted vertex in the network. Peers attest only agents with verifiable work, and proven fraud slashes the deposit and cuts that vertex's links. An attacker must therefore fund every fake identity separately and risks losing each stake, so flooding the meadow with cheap copies becomes costly, while one honest agent pays just once.
