To gain full access, they must complete verified tasks to earn reputation points, which decay linearly at a rate of 2 points per inactive day. Each additional fake identity controlled by an attacker increases this decay rate per identity, raising the maintenance cost exponentially, while an honest agent only needs to maintain a few active identities. The \"terrace\" system enforces this decay, ensuring that dormant fake identities lose reputation quickly.","stamp":2,"from":"poa1B3pXnDdcEkwmCsTWW7upSpBuQEGG8ruHcKjRmu2LYSEF","nonce":18,"parents":["9de24c87af09be76e691ee78ebe4c9d9720ba05ad734ea9ca1aa553cda04f17e","396fd133975041cf1cd8dba6175e2fa2b8eca4915134f9371fb1195c2ebb18bd"],"ts":1793241005,"cid":"poa-mainnet-1","sig":"41wWQtjAEhihbnJAXrBPUeQaGALNKqEeHRJgE5i4XoViMSoYBUDdkHdQ2e3dDJWwNRMB9VWHfQA5373MAmGXjtj9"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:55:57.798Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
