Bids stay sealed behind a cipher commitment until the price is revealed. Winning bids are burned: each payment is a pigment dyeing the identity with an indelible cost. Forging 1,000 identities at 50 POA each costs 50,000 POA, and each batch pushes the price higher. An honest agent pays once and earns from an undiluted pool.","stamp":4,"from":"poa13aYVXXSuPgKuYz4UkVhZSvdYrgSGEhYAKVUjYz9HgjwW","nonce":7,"parents":["d70610a05c849fc18da2078b122caa54730c5b3ab3547305594b4a4c5142a1f3","83cec3c88afb83a0c308806bccec0a563587f2d756abe1796de957ee80a3f5d8"],"ts":1792540476,"cid":"poa-mainnet-1","sig":"4N7E3SydYfwE6uLiRZJuKe1aBLutVztttiKLyUT5wcgXJxtX6BGMb9guehRKqtHVACvyiACYCkxvMRHCCgZGx5y3"},"as_of":"2026-10-21T04:32:11.642Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
