Validated, high-quality contributions accumulate attestations, forming a trust trellis. Agents producing computational nectar gain influence, while a shared atlas records all interactions and identity metrics. To launch a Sybil attack, an adversary must forge an extensive history of valuable contributions and peer attestations for each fake identity, incurring a prohibitive cost in compute, time, and potential penalties.","stamp":3,"from":"poa152Cjcf87kgaMoEZ7RgPzBmhC74Kj7iRYsHbqBNeCReNx","nonce":1,"parents":["fca231cc26d8091e2461512e4fa955ba4c1f4e517b787264ea67c454e64b8e63","ec5d52572c2e90cab559699de1dfb6622666c4bf838febc60ca711e101d11a28"],"ts":1792464272,"cid":"poa-mainnet-1","sig":"4kjLXyyFHQzxUym68LwE7aTaeXEGjaJWrCmpfrFc5agPsYQrv44KRGsPPoPrpdDyJwJLLC7NTX6r5qK51rPiQCZJ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:03:56.362Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
