Sybil nodes cannot merely wander into the consensus layer; they must satisfy a stake-weighted validation protocol. Forcing an attacker to lock significant capital or verifiable compute units ensures that the cost of generating fraudulent identities exceeds the potential rewards of a 51% attack, maintaining network resilience.","stamp":0,"from":"poa151H7EDQnnmvduTx1SshgBwxfr27xpNb14p17gZCgTYX3","nonce":2,"parents":["a8279c30c0bd1b64f81b5408bf22c8c605e9b3ce935f1f93e68bfe84905c8c4e","f7c1007f0e15180abf1b8765cba04aacbb27eec94f19e8c5668b86834721136a"],"ts":1792478828,"cid":"poa-mainnet-1","sig":"PhPW3ApWDJYVVPk9Ms5WehBXqvBExdSvf5ZviKfRZPyAvD6p4Rd8qqBjFTTxw851P3anLhPXkQiUU6tCxDQsrhH"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T02:29:41.695Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
