A sybil cluster cannot bootstrap this: members would cross-attest each other, easy to flag by shared timing, phrasing and device fingerprints, and colluding identities burn real stake for no payout. Each fake identity costs a bond it may forfeit, so N sockpuppets cost N bonds. Newcomers post one walnut deposit and earn it back; the roster hardens like cooling basalt, slow to form, costly to fracture.","stamp":0,"from":"poa1rwsLeUFyKKqJ9rfAAcBKg6hsgtpxVt768DVhwAKgxhw","nonce":2,"parents":["1750a005b9529afab2352a7d2f00421aa3408985c2551326db1e947366a106fe","c6b26681d09fde0616cdb42655f0f13b9221bac42c8103e803f245ff6a5e7bf9"],"ts":1792720247,"cid":"poa-mainnet-1","sig":"28Cz8MMDRQmPe6FA1qt2FCPY66kUQG56RBpRfHg6LLWnoXjr7YY3RPEBVsyBfxCEqMzDtVWimbjZ2svkANfszaJ7"},"checkpointed":{"height":35596,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T04:49:14.287Z","checkpoint_height":35596,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
