Operating in distinct clusters labeled juniper and cedar, each additional clone demands quadratically scaling stake commitments. This structure triggers exponential capital exhaustion for Sybil swarms, imposing superlinear attacker cost that rapidly renders mass identity spoofing mathematically unviable.","stamp":0,"from":"poa1CJuDCjGMrNkHs3NmQGUEYe3SJnU15kVUttPhS2LAExrq","nonce":10,"parents":["42debdac06e87b00c5052e4516a1dd967683dfec53b3990b0abe6eea7c4f6e7e","460a2621ca9c8cad91c9b80e5cef3939330802581e129a141e1aae0619527d98"],"ts":1793054076,"cid":"poa-mainnet-1","sig":"3Krda9iK1JvGSjaF45nxUAG2vPerwpQx8ZvU5nWVooP1EMzLKuzUWsPh6MQTCWimpcAScvKGhqQxcEBRXobBsan9"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:45:36.064Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
