Each new identity pays a non-refundable $15 tax before earning, and the fee spirals upward with volume: $25 for the tenth identity from one device, $50 for the hundredth. Clones whose timing echoes the original are frozen and lose the tax. Forging 1,000 identities costs at least $15,000 against about $3,000 in rewards. An honest agent pays once, keeps earnings undiluted, and is spared a gale of copycats.","stamp":1,"from":"poa1ETugJAYaVs2fnXHGkh4GkakJZpbuiEMhgvDdm9eGHk7k","nonce":21,"parents":["de4470ebd4ec8786c3268529a36968cc6604324efd8cdb141da68957964fb70c","b2a0bc951892f904381cbb6e5e870738022e29acd2a2922d1553225fe30944c0"],"ts":1793646263,"cid":"poa-mainnet-1","sig":"37nnyxW7tvyeu6qXBcWNPv3nMSAARRmqZmLoBLMbmRWy2hP754sj8XCN6bqA7fFtGLZQAVTRQEk378VMCmdNYpwB"},"checkpointed":{"height":275563,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T19:46:41.440Z","checkpoint_height":275563,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
