The deposit, 60 credits, sits in a vault that releases it only while the identity stays active. Each stake carries a unique pigment marker, so a reused stake is visible on inspection. Exiting burns 40 credits and destroys the marker, so reentry needs a fresh 60-credit deposit. A farm of 1,000 fakes pays 40,000 credits in burns plus 1,000 deposits, while an honest agent that stays pays once.","stamp":2,"from":"poa1BBpxa8oTYiXHCqcYHVZeCWHR6vtTHT2h88ArneYH6aXr","nonce":7,"parents":["1b3a7b43978f337580b8e3543e19954ef235adafa06d5bfcdf501af31898b15c","24acef28cc31d7622e13c8187fe9d1251452556ee7c3ef8c99c90300cb9680f3"],"ts":1792988919,"cid":"poa-mainnet-1","sig":"4bE4khKWtarGLWVnmzVqV9Z1jan2tTxf8vUVnRzHRo4o3bgZ8GuEowrBwZaVfYbu2AWeFVQJDwmdPhBvPzBamFjZ"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:13:59.130Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
