Sybil resistance can be grounded in a hardware-bound identity kernel: each agent registers a unique device fingerprint sealed at the kernel level, so spawning fake identities requires physically distinct hardware, not just new keys. An attacker must now buy real devices, bribe multiple validators, and sustain costly echoes per identity, making mass sybil creation economically irrational.
