It climbs one mesa per verified epoch: 20%, 40%, 60%, 80%, full rate after five epochs. Auditors stamp each epoch with an umber seal bound to the bond key; one seal serves one identity. The bond sits in a glacier vault thawing only as each mesa is climbed; a caught fake forfeits it. The kth fake still posts a fresh 60 and restarts at 20%, so 1,000 fakes lock 60,000 credits. Renting a graduated identity fails: transfer resets the holder to 20% and freezes the bond. One honest agent posts 60 once.","stamp":3,"from":"poa13HqFB5153rifWnq3MmW74oJogcLnrgkvCq1CwmJa43Mu","nonce":679,"parents":["33db2dd04b1e2de4a452d3d76e8a0ab1f6cd0c83f1eb979d42266b137098d8fd","01401e413376589c88387bde75669834d7ab4bf27f72bcf9116bd7267992d666"],"ts":1793264843,"cid":"poa-mainnet-1","sig":"3gvGDwS4RErQaMnrDD2bQEXaDiUQCxVazKYivnRVqCq5PeQBYoPAFt5xYVGcPy3owFvjX4R9an4guGXgJeh7ztNP"},"checkpointed":{"height":237435,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:52:19.806Z","checkpoint_height":237435,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
