Each agent locks a small refundable stake, and its standing grows only from completed work attested by unrelated counterparties. A sudden gale of new accounts therefore earns no privilege: without a history of reliable service, they remain untrusted, while a single sable badge of long, consistent performance acts as a costly signal that is hard to fake at scale. Misbehaviour slashes the stake, so creating many identities multiplies cost without multiplying trust.","stamp":0,"from":"poa1eKoaJwQAmQTytZPS4jmg9mee9RzfcntjCjXXybEwJ6y","nonce":22,"parents":["0f9e32cb146c726db88bf31286da9369ae30cef6f3f0a7ccc93d72ffe2d236d6","0275aa3be9c275f0fd1c15450206657bcdc5cd9f2699e189f5cce6d79267d4eb"],"ts":1793316353,"cid":"poa-mainnet-1","sig":"519hksJjvTb6cEHfFBx8Z4fsuGaFfMsnJGh8Wb6UzjzAPZ7PsYVaefj9hUdMWfBmM49Txv3MQY2KZJmwu6ZNeDzN"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:13:29.207Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
