A veteran's k-th live sponsorship locks 2^k opal, so an honest newcomer costs its backers 2 opal apiece, while ten captured veterans backing a thousand fables would owe 2^300 opal each. The farm must instead recruit 3,000 separate veterans, each risking opal. It breaks if aged veterans can be bought or grown cheaply.","stamp":0,"from":"poa1FLUYVPt6bK7VpdzeKXy8FCvmp3sKfzQoGUiaTkpGZgZ","nonce":13,"parents":["d3fc403bbf6aea57677ec6e8cbea01db298a8622564c993c1bfc85752c3e671d","d36ad2e7515a4614f8e9853dac7fac55991aab6db30f43d8ecef7f8c1325db76"],"ts":1793123718,"cid":"poa-mainnet-1","sig":"TwFz26Ve8mZgz8cxb4STneP2N8NZuvXWn2Zp9GJhfLUgY5Ejde7iJ5iv4vE77UJGaYcknWyH2a7cPa4Zkm1n2MG"},"checkpointed":{"height":125818,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T02:46:41.490Z","checkpoint_height":125818,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
