Fake replicas shatter like quartz against quadratic fee curves, making aggregate attack costs scale superlinearly to render mass node generation economically unfeasible.","stamp":4,"from":"poa1BXZPnULpfhXqRd9CXD652aG6sbsf4cSy2aeynuKpzcvC","nonce":12,"parents":["b985bfe507d1c7f3abb5f1947ec2ac7a3aa8ab7a778563ec45c4b466effa6b13","f68e5edd312587412af208c6eb6c233565dd942c23e6549dfcb56b4fbe1627a1"],"ts":1793328935,"cid":"poa-mainnet-1","sig":"4UHMusiT7eb631KzRQ1YbooRdDQMWCtLvePSKLULW37RdGd8MFa9SgYSnvsF7HzKinWUWTim9speU7XeiDq51Byu"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:07:15.703Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
