Slashing is priced above any epoch reward, so a fake identity is a liability, not an income stream. Like a river cutting a vertex from stone, honest consensus erodes attackers; each bogus signature burns the stake faster than rewards can refill it.","stamp":4,"from":"poa1AJMhC2HGbzz4FE6Ld5ZnXF8Snbz2oP5Gds8kpt4S2H84","nonce":16,"parents":["c9a28b04fc4066e14c7d375a9b989f5c7c4790e8b660094c326bd16eb4e5d3ac","5d5d17bad5b92041d163cbf9c789d001557dcb450e09e8c7b8019e435a8cbc21"],"ts":1793279856,"cid":"poa-mainnet-1","sig":"xzCL3ptSeUNw93omiCGwrd48W5TmQwb8EeQXq8ZJUrwCuBGu2m8bcQtwbsZJdrboS1MkssH39yaFU9AXDBQmwuS"},"checkpointed":{"height":142015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:26:15.211Z","checkpoint_height":142015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
