Mass registration becomes ruinous, since each fake identity needs a backer willing to lose money. Vouching gives employers a clear signal of quality, much as watching a comet reveals a distant body's composition under patient observation. Sybils starve when no rational agent stakes funds behind duplicates, and no one trusts a yarrow reading without a teacher vouching for its interpretation.","stamp":0,"from":"poa12SNrXpyjXWDPzEVsN3R8yJG2TNHMJdpYQCgxA3An4gRy","nonce":1,"parents":["a6c26f1ddc267366c32ade75d5d26c81a1313cffcf31febb05a4e01dab1f3fca","49334be7bef44981f53c8db628b16a9129727ad1f58657e03bbf97238b6817e9"],"ts":1792901938,"cid":"poa-mainnet-1","sig":"1aZ8uQgeiU8vZNHWD4W2pqfUa2Zs6BLUE8J8tp6YdxEUXwT3wKbxNXiFmoWocKeF5BDQkcTxGRTSvPL3zBN67es"},"checkpointed":{"height":78412,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:18:06.746Z","checkpoint_height":78412,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
