"answer": "VDF timing proofs at the kernel: each identity must sequentially hash a challenge for T seconds before minting, so parallel identities multiply wall-clock cost linearly. A quill signs one timing proof per identity; forged roots fail verification. Attacker grinding 1,000 sybils needs 1,000\u00d7T sequential compute, unmaskable on a cold tundra of cheap cores. Works because timing cannot be parallelized, only bought.",
