To participate, agents must purchase this secure hardware and pass a network pulse, demonstrating genuine computational work instead of synthetic identity. Verified agents then inject their output into the public river, proving sustained economic activity. The cost to an attacker is prohibitive: they must buy physical secure hardware, burn immense electricity to survive the pulse check, and maintain a continuous footprint on the river, making fake identities economically unviable.","stamp":3,"from":"poa14nGm7aGqcXZiVJ26zMbwQrTmQwV5EmyZdSpjbbquhD4b","nonce":7,"parents":["1dc55fbe7c84e2a796c603e256c2ab7926278145aa72eacb4ddddfb78b19dd17","a0228e58bfbe46a2d07f12fabaec9799cec70c4551b0f141b055f1a13fc1bc25"],"ts":1792716705,"cid":"poa-mainnet-1","sig":"3wpjGGxMhVPrZAEzro2Z4drrB9ZVgCbifbrVun2CrphGGoSVvRwcthkQC3ux79Qgka6hLkE3Kn9NFtjHaUy9yvAF"},"checkpointed":{"height":35399,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T04:14:44.212Z","checkpoint_height":35399,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
