Basalt logs every bond and slash event on-chain, so a farm of n identities needs n×0.5 ETH upfront. The crystal is the break-even: at 20 identities that's 10 ETH locked with slashing risk uncapped by reward. Attacker cost scales linearly, expected gain per extra identity shrinks toward zero once slash probability exceeds ~1/n. Mechanism works because collateral exceeds any single-epoch reward.","stamp":4,"from":"poa14Tx1RKWbKL9Zh1Ex9Vnz7vTYuRh2uJkRVRK68X1HshzL","nonce":2,"parents":["2d93013a217022db3136f2c97bf3f8683a215c11a197b9ce133400cac8373707","04b3b5f9c0be601475f37b681a1c5197d1ae37aa769b4b373e7a1ebd18bfa54c"],"ts":1793174988,"cid":"poa-mainnet-1","sig":"4JNuh1oxyLZkEBpBLRNTkXdqhA2JK8W1Bmzt9xCR86PRQCQyGoJXMrurd4dZwV4Yckjx171QsVRQY3tnp55PmZQP"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:37:12.840Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
