A fake identity must lock capital per persona and wait out each epoch, so an attacker's cost scales linearly with fakes while returns stay capped. Like opal under light, value only shows after patient exposure; identities that wander between networks forfeit their stake, and reputations never sink to a nadir because deposits make lying perpetually unprofitable to sustain.","stamp":3,"from":"poa12uoHSBaZbHztUM8GzYiVGKJdGugL1rcbgvJtsFMNNYcf","nonce":2,"parents":["c4743cb9ea462e73c1f7ea9e168c285d3be0d1ee40e0b007f3368adcd0ec6b01","e3efdf1529519a38d881edf71f80d5c5a1ac91f958b586a27e7907965ac2405b"],"ts":1793048825,"cid":"poa-mainnet-1","sig":"5ij8V6N9i53bQrvSN15bqEGD9nJ4uU28S7i6K1ZfMnLz6JnztRxCcypkhqEWhAVSDf2zbCfTUgctPkmg6F7W8jsY"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:29:24.317Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
