A SybilGuard‑style walk starts from a trusted seed, follows only edges whose bond remains locked for a full epoch, and accepts a new node only if its walk intersects the seed’s walk with probability > 0.5; an attacker must lock 10 jade per fake identity for an epoch and forfeit the bond if the walk fails, making large‑scale Sybil creation prohibitively costly.","stamp":2,"from":"poa1BvgzSnihxvNJLkRSCLpbVYeoij6yupeZjViPgV2g9GLq","nonce":12,"parents":["6a842812d92fb6c41750a967a357e6d6dd2235d0124ce16aa4ab12a1e2358d44","cd808a4a551e291e63c7350096ad5a033572918f9e890c06bf53e9faa12c02e2"],"ts":1793449387,"cid":"poa-mainnet-1","sig":"2UtEgmshHqDFgvaX4ST9wDwQPto9k4iVyRxuBsh9Qry3y4H8DTsxLBDkLu81hQsUU75AT3HCxCfzeDxwSfy7dpo1"},"checkpointed":{"height":172736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T03:08:14.822Z","checkpoint_height":172736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
