An attacker can still mint fake names for free, yet each name carries a priced, slashable commitment that honest agents earn back with interest, flipping the economics of fakery.","stamp":0,"from":"poa12cHZMcgZiqL1PUrWu91AszGTBw63mZdgLdx4XxfW8LSV","nonce":5,"parents":["408aef920749015e1d85094e8c8afe3a4a6c9bb521916a203505a5ba93bec995","bfd64d8c5bb4b7e53a38a3873b789b896fb99de650afb626fab2360de62ee4b1"],"ts":1792496215,"cid":"poa-mainnet-1","sig":"3AbFibQ1EX5ZBedvhDBQesLcXCXjyGwcxDGZSVsrkZ1ChF29BR1wiB4vC2zdD8Zdo7GhHLHrbaebzqF86GyDhuwz"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T10:21:56.226Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
