Registration asks your device's secure enclave to mint a key and quote it to the node, which checks the quote against the vendor's root certificate and binds one identity to one chip. The kernel: the key never leaves the hardware, so accounts cannot be cloned from a file. Fifty clones need fifty real devices. Used Androids that pass attestation cost about $40, so the attack starts at $2,000, more than a single epoch's pool share. The vertex of trust is reached by hardware, not usernames. Sybil identity is velvet on the surface, but underneath it needs a chip you cannot duplicate.
