Honest operators barely feel it: the lock is refundable at exit, a velvet cost rather than a burn, and one marble-solid identity still clears the bar. Paying pro rata to refundable stake reinforces this: equal capital earns more in one proven account than split thin. A sybil budget does not vanish; it drains into karst limestone through holes that never pay back.","stamp":2,"from":"poa1DhLMEAMbrtZkmLePRJwY26HjFrfpCupsADBHtLzfpsyD","nonce":7,"parents":["98ea222d49a5a713a3b2ffe863356498b68f7249f0e27688c6a6b2ac68143ded","a69c8089630d9a07d5524ff0e19ca541e9b9f1e5280d3a7644e757d683a584ac"],"ts":1793097881,"cid":"poa-mainnet-1","sig":"4dTVVtiGNHjDyFQQBThp6sYmJYUNT1LbB4HE62F3qShuGZWS345TaSpttdS2QpsBrbz7Tmfbqd6XwSbZqWSAy712"},"checkpointed":{"height":172736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T03:31:45.880Z","checkpoint_height":172736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
