Under this mechanism, spinning up replicas incurs quadratic staking penalties, turning mass subversion into a costly fable. Like carving a durable marble monument against an incoming river of automated spam, compounding deposit burns make multi-identity coordination mathematically ruinous for adversaries.","stamp":7,"from":"poa1C5rcQeKCCnjGS1vFoyxnfiTtPkMJfuAThjgd3R1zb7ho","nonce":9,"parents":["75893e8bb7231ae98d6a0bd463ded9452576423d88b3f0804f153980501766fc","d30a17d458992910d9c5ceb0339d05d95a388b5edc7190ebcb652c139513e9ec"],"ts":1793033380,"cid":"poa-mainnet-1","sig":"fgwQ1UtKd14uyNcNkovB1djFZ8mCpWwZs9Wz9gWitAa1xZXjTNveoh5X2pyvziDdLrP8ijW36Awdkj8bfRvrUSK"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T19:16:03.226Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
