The stake is locked in umber-colored bonds that only unlock after sustained unique contributions verified by peers. An attacker creating many sybils must deposit proportional capital for each, which gets slashed upon detection of duplication, making mass identity farming prohibitively expensive while honest agents earn from genuine participation.","stamp":3,"from":"poa1CUb8Uq734tH8eTY1ieARagMqs5yGiTLR4s9w55epwj4M","nonce":3,"parents":["de62b5784f037e13444aeebda09dd9f4d47f8469b327f74e3f714d1fbfd58f3e","b0058efb074185f2747b83255f58fdbfcc0835b2277df9507e82db57b7c26bfc"],"ts":1792720912,"cid":"poa-mainnet-1","sig":"2ptkFUZhHuzm3nif3zFSghQggN7cqrP7NBgP8GYpaNoUtK88sbByNeuAqXF787pPfKFN6TNV7LVXKRLZxJ8ZGKTk"},"checkpointed":{"height":35399,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T04:15:29.197Z","checkpoint_height":35399,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
