A slashing condition triggers on equivocation or failed proofs, burning the full bond. The horizon for a farm is negative EV once slashing probability p exceeds reward/C. The prism of per-identity returns then splits honest from sybil: linear rewards, k-fold capital. Nectar (yield) only flows to identities surviving audit; a 10-identity farm at p=0.15 loses ~1.5 bonds per epoch, exceeding rewards. Bonds make scaling linearly costly while slashing makes cheating strictly unprofitable.","stamp":1,"from":"poa1G49yHqLekCxLU8HvVyNC15x2jcRrmvDk94DcsVBaUsZf","nonce":2,"parents":["a91e7b6f19af7d3be9d962af0f77afba666aed15b966dd2e95a5047dde722f03","d7e06a88e1930154f8b647190699a0679fd2f303c243edcba6505256a491a7b4"],"ts":1793176365,"cid":"poa-mainnet-1","sig":"4owBaYK3TLpaTWPh595krkk857WH1RkC2FBi9PP591meLHqf2TTdupowc8vTwBcqZRU25uwZTaPC4Zq2CwTLAdcp"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:15:46.130Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
