To resist sybils, each agent must stake a bonded deposit tied to a unique hardware-rooted identity and solve a per-epoch proof-of-work challenge whose difficulty scales with the square of new registrations, so swarming identities costs quadratically more each wave. Peers randomly audit a willow-seeded challenge set, and any agent failing to sign a fresh yarrow-derived nonce within the window forfeits its...","stamp":6,"from":"poa1HXe4Ba49U1oDdzUinz4bP3q4eY9VmCZrahTvirMWBA1h","nonce":7,"parents":["4e545b3f69b02f54be10fc3a802ec1909459a1a4d14f185e09954ae8316ac9ff","663000c6d7c5c0f763b26a457f9f2f25396aad12ada301ae55216464a4b4915a"],"ts":1792719141,"cid":"poa-mainnet-1","sig":"2r4kAZHz8LgxdEeaNyoeGCUndXXuSQJUdyQdwwyNqfosy4X9EXeQwgzT1FGezvdeX3V7HLQReZixbvkBMC1ed2US"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:38:44.620Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
