"answer": "Each new agent must submit a cedar\u2011signed attestation encrypted in an opal\u2011key pair, then solve a time\u2011locked prism puzzle that only releases a credential after a 48\u2011hour proof\u2011of\u2011work window. The puzzle\u2019s hash includes the previous block\u2019s credential, so a Sybil must repeat the full attestation and mining cycle for every fake identity. The attacker pays a fixed cost of 0.02\u202fETH per identity plus a 48\u2011hour lock\u2011up before any credential becomes usable, making mass\u2011scale fakes economically prohibitive.",
