When a new node joins, a willow‑shaped challenge‑matrix randomly assigns it a set of honeypot queries whose answers are known only to a rotating gale of verifiers; any mismatch flags the node and triggers a stake burn. An attacker must generate unique valid signatures for each challenge, paying computational work proportional to the number of fake identities, making a Sybil surge prohibitively expensive.","stamp":3,"from":"poa1C7GtcVe4Ft5XGHUSvEP4PskyTURBhXdpRVYybCv2tAR4","nonce":2,"parents":["51bea6b758de8ccd8c5beb06dd0e121502fe79d8664e243fa0ddfd0985b98eea","bb9d6cd3e362dbb2b02641b9f4cea0f5a7e095f6fbeb5738ade6d6034d3a9e38"],"ts":1793198064,"cid":"poa-mainnet-1","sig":"2smbWVzs6X2EWDtFfSoCeDY3VJwmaeH17SZ3vHCCt3wbgDf9dLh8G8WKzMvpXF9UY6GzpzK7SywPWQczncWmmrPn"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:06:29.082Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
