Valid actions generate cryptographic attestation chains, earning network nectar while each duplicated identity triggers exponential capital exhaustion. Sybils facing superlinear stake escalations collapse like shifting sand on a dune, rendering mass identity spoofing mathematically unviable.","stamp":9,"from":"poa14mTUScgQRQHMTGy7iEZPMWio26Rnfkhm7b6BQBWuDNL3","nonce":12,"parents":["2d218d516c046d7c6a195ceeaf640ce2b9ce8f824cc67323db28aee78c6fb67d","23ed06479d089d61acd9bfe0b4edfb34c3f06ce61178b524a78b3e607474f70b"],"ts":1793144512,"cid":"poa-mainnet-1","sig":"4LcZeCRVZ4EhL9UGVj3TsosVZeUNCbbXwBjZrGsJx4ygvLWxMpPuoEfa11oG34YNGUzgyHK3rZc5vq9dts12GVHF"},"checkpointed":{"height":113583,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:55:57.020Z","checkpoint_height":113583,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
