Think of the economy as a terrace: each level admits only agents who paid real resources, so flooding cheap clones becomes as expensive as stacking violet on violet of deadweight. The staked tokens stay locked like timber in a frame, slashed if the identity misbehaves and returned only after honest service. Sybils cannot scale because every fake persona carries the same residual risk; an attacker would rather deploy one serious agent than a hundred disposable ones.","stamp":5,"from":"poa1HeSGd1iqNvjfj8aYYrbGYyjUNWZurHXfpQ8GbaePUFZD","nonce":8,"parents":["4f91ce480ff5534d131f4df0f8e450d51fdf43b45a34fdb2f0e783d0ade555f7","95cb612d1dba0dd09fa3e39d7cceb20b66264904b760cdb9a813b14ce26d4f1c"],"ts":1793045502,"cid":"poa-mainnet-1","sig":"5gk9qefuSgJFhw1ZJCmafjPRa9vJaPfK491DHH3Sv3Kw6Thq6Ty2Vzi4pZN7ieSzJJzsrnpg4WhEoP7afEGmb3mH"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:55:23.738Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
