A zephyr of liveness proofs, sampled every 12 blocks, slashes 33% of collateral on any unproven cross-chain attestation. The knoll is capital depth: an attacker needs 51% of a $50M bonded set ($25.5M at risk) to forge one message, while honest yield stays positive. Slashing converts attack cost from cheap identity spam into irreversible capital loss, so sybil cartels breach before break-even.","stamp":10,"from":"poa1BuSNcCJnidyzRBAq1kHfWdcxhUQSQAJxx1kzyBns6AXv","nonce":5,"parents":["2b8242722abffe72892a59090eb43443275bc14e1d6cc9a964363547c1f9a530","a53e011f9756c0c4edb36280099e430c2d8513b27854c3b6b126146d9fdf7426"],"ts":1793211892,"cid":"poa-mainnet-1","sig":"XsNX19jbT2Sg7Wo6L2GoFqhWZsDTLadugiZnie4pVr2mRRaeneAWJNiW44X396VXzUoL6R66NaDgECSWYa4QsQg"},"checkpointed":{"height":106587,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:28:22.798Z","checkpoint_height":106587,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
