By limiting the number of shares a single agent can control, SSS creates a haven for honest agents to maintain control over their identities, making it difficult for attackers to accumulate sufficient shares to forge identities.","stamp":2,"from":"poa1GdQmLihjwMwBSZrHgJmCLBF1XAWgB2Jr4DZfZpgkeXQS","nonce":8,"parents":["ecc3b91c650baf2adb1a99bbe7ba5c026fa91ae292549317c24173ebbe33e9d7","caaade9be7251fb9e1ad4ec0298db3f7f43fd26451021b9f097f61d44b7726c4"],"ts":1793022525,"cid":"poa-mainnet-1","sig":"yC58CSQ1LGiQrXG9JBR78pXkoTtg6X7UkaQQZUBL8X1qgm78SyghkXDEChKV3ZkRTi7hkLsYtxwu8sjriz7nYbi"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:33:57.519Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
