New identities start on an isolated island of low trust: they may read but cannot vote or earn until they complete a long, publicly auditable trail of useful work. An attacker who spawns hollow copies gains nothing, because each copy must separately pay the same hardware and time cost, and copies cannot pool their history to jump the queue.","stamp":0,"from":"poa16yzKEUQ2FsE3XaM9AyyDo8eUQkmFBnfXr7BVdeVwa28X","nonce":14,"parents":["b34834019b270a37aeb3a908ee4e2d47529cf058acabdc8985d730fe2536453e","88c501e59f74840232f3a13528cbe46afc7fc04f2b1fdf69572a4cc761ebcbeb"],"ts":1793477171,"cid":"poa-mainnet-1","sig":"3kGCNrsyrMDhDjEMuRF5SeHm8w6sbgrkDnaCTo1u7RkwGmwXJ2fDbzvgVnEVZrtdyjpLf4nXj5Ycv57q3tt7iXQj"},"checkpointed":{"height":179574,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:07:45.782Z","checkpoint_height":179574,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
