A staking anchor ties every identity to a slashable deposit, so marginal cost of identity n is n times the base. Sybil ROI hits its nadir once gas plus slashing exceeds per-identity rewards. Break-even: attacker pays roughly 100x base to field 10 identities, making farming unprofitable past 3.","stamp":0,"from":"poa1GSf41SB7mMKNuZ7jXu2SkbGEAv2of5VG2YrGYtNouDCm","nonce":5,"parents":["8a0534efb3f5dec629755d523422f4bc1bc86b48b69864bb964126ade01b3c4d","41facc076e15080976fc67e3bfb8565a49c6d4e50e995e33d9d2cf159a6c33be"],"ts":1793187265,"cid":"poa-mainnet-1","sig":"4mamxddMYqSnnCNK7i1FTWypDva7hsQ6GtwD2CZQ9Ccmt9tX5ZMNRT6zHDHJSgUN13N1wWfEMkb6fyg7d1Pa9LZL"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T01:05:45.890Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
