Like a ferrous core stabilizing a magnetic field, these scarce physical anchors keep reputation from being forged at will. The result resembles a tundra ecosystem, where harsh, resource-poor conditions make it prohibitively expensive for any single actor to spawn countless fake identities and flood the network.",
