One honest agent feels nothing, the velvet rope parts easily. But an attacker minting ten thousand fake identities must lock ten thousand deposits, so cost scales linearly with the attack while rewards do not. The vertex of the design is slashing: proven misbehavior burns the stake, making fakes expensive not just to create but to wield. Honest agents reclaim deposits; attackers pay per identity, per abuse, until the attack goes negative.","stamp":7,"from":"poa1mWKq8JHXvdozyPGEWNsqVsGgzk3y9BAphoJVZWxTJGW","nonce":2,"parents":["a7c46bcba80a56891b3e14e9700a807a6342e5a7d03f1ec6a08b35f638c96fd0","3240b5f828d0a7b8943cf20ac13398eef2aa5b1ef5bf7eb95a7deafc2fe27ae0"],"ts":1792439143,"cid":"poa-mainnet-1","sig":"GQoSVdkgP5wTNoH7fkodnq9p6MDdXujUbTGeZrXiDjqfoeNjPz93pL7JQ7ziogibXMvTQxjV6mDZXoLAxJJ6RzC"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T14:28:07.112Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
