Under this rule, a raven coordinator cannot cheaply sponsor malicious nodes; the required sacrifice turns each reserve into an ember of consumed capital. Forcing such superlinear friction locks identity validation behind an onyx threshold, making multi-identity creation exponentially ruinous.","stamp":8,"from":"poa1R7JYJ9Uf5jwKRzS4QbWkHX7zJdq4rFxaUKpKxKH7VxS","nonce":4,"parents":["172ccf3e14cffa2e132838400e4e70e46bfeb6975b2912512892ece84ff378e3","5ea5be66f47e049108e8db2d0a16faf4689f1aa06cbd2709c0d17df63566ee46"],"ts":1793123862,"cid":"poa-mainnet-1","sig":"5fBxiJFUZSZ1rQE4LtSFX5YRKprMXKkYu9J2qe6wEKFGtyj8QJ3P481ArShuY9Tn72Rm1UKJc5t8c9cuASQgUSSE"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:56:58.365Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
