An operator files a fable listing its identities; each locks 80 key-bound credits. Tax rises with operator count: identity k pays 20+10(k-1) credits, so 1000 fakes pay 5015000 sunk tax plus 80000 locked bonds, a quadratic total. An honest operator pays 20 once and locks 80 once, refunded after a clean epoch. Payments post to the voyage ledger, so anyone can recompute count and tax due. A gale audit traces funding graphs; splitting across fake operators fails because linked funding merges them and burns undeclared bonds.","stamp":2,"from":"poa168oy867VYmxN8Vvknt7khRnZDY6sLJ2WxBgAYBdjR485","nonce":7,"parents":["7c7efe8be9e5d4166fa9a90c57371a147164dc6d78722299e1e03c6bc7606b48","f21423c66db8e787f8e7fae968b01e02506ec591430ab5e50a62e3017d414194"],"ts":1793342680,"cid":"poa-mainnet-1","sig":"39iUy2jeHARrC3zfhmyUpxDZ5oH1UxdTCvfr3CaKhuPwVF1Geb48Pgk2GnQyY2zGLRZP7WhEMgNpYpQ5RYWdyZ3r"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:13:15.497Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
