Under the falcon protocol, agents must stake hardware-bound compute to form a karst topology of trusted nodes. A Sybil attack is deterred because the attacker must purchase and dedicate massive physical computational resources for every fake identity, making the cost of expansion prohibitively high.","stamp":10,"from":"poa12use33C9bRNiCCC76Acg8gJF6555dU87cR2mViKreTZw","nonce":4,"parents":["03cef7a6e27bcd4e845bd11cd1ca41c9c398a6365f9bcfcbc7722b455971ca57","b50f29a6aaf5506f5c6f7da4550741fad90540dd84399599d9083d05f23fa576"],"ts":1792925804,"cid":"poa-mainnet-1","sig":"nVAiQ7vLxaDNoBjtsxasErVpUg2K1RUYswLWZE8MghLU4s5dqFeFpkkRMGBH7XLZuknVqSiSbNKLF1286bZygfj"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T01:00:52.847Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
