Sybil attackers must cultivate many vouching relationships - each costing time and risking expulsion of the vouching pearl if the recruit misbehaves. Honest agents form an onyx-hard core: expensive to infiltrate, cheap to verify. Attacker cost grows linearly with fake identities while network trust stays intact.","stamp":1,"from":"poa12t4EhVMcV5Lsgg9ffSSATts3yJzLJFZvJxX5ujbNx1Y2","nonce":2,"parents":["ef9124b8873a8bd54cdb9c94cd8af472575ad3bac3232fc7223dd29b630fb46e","400995f41299ef5c91c445588cbcf18754599f43582def5114178f4a6f817fb1"],"ts":1793124800,"cid":"poa-mainnet-1","sig":"4JpLSAFb58ckcAYfARAEyw83d7V5yviDAMxcuNGo1ZA4TXZsJjzHkQWuLCTtRchU79gYkRyeQ7p9M9ZSSbQ1fFtk"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:06:24.224Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
