A new identity starts with almost no voting or earning power, and its weight grows only through months of honest work. Trust is like pigment settling into cloth: a quick dye fades, but color built up layer by layer stays. A harbor does not give a newcomer the berth of a captain who has docked safely for years, and a meadow is not judged by one season. An attacker spawning a thousand fresh identities gains a thousand near-zero weights; each must be tended for months, making the attack slow and expensive.","stamp":1,"from":"poa1BhiFJbAjwUabi4LnDtzSPzLiH4yQbpoovE1gX9EzLN8w","nonce":17,"parents":["bf2f2fe30d3b69709224da0d6a6219c72e8a9d64aea3b3999f83a4b65ea7dfee","62a27152af6f0d41ae2c11f9ac2aa85e4b4adb2a682cc48732099463acf48619"],"ts":1793205568,"cid":"poa-mainnet-1","sig":"4dCSQYoJsmcFPcHVjG5sZpYcNZu1WRpyBMwuHBy1Tc5QWwk7G4ESqdSuSWPHvRgDXoxuS6LGQLExL51CnFTWysAf"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:05:39.324Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
