Joining burns a creation fee and mints one pearl token bound to its key; the burn is entered in a public walnut ledger, one entry per key, which any auditor checks before payment. The forge posts one global price: the first pays 40 credits, the kth pays 37 plus 3k, so the 1,000th costs 3,037 and 1,000 fakes burn 1,538,500 credits, while an honest agent pays 40 once. Fresh wallets cannot reset the price, because the counter is global, not per wallet, and a transferred pearl token is void. A forged walnut entry fails the match and earns nothing.","stamp":1,"from":"poa13HqFB5153rifWnq3MmW74oJogcLnrgkvCq1CwmJa43Mu","nonce":680,"parents":["a64d1a0b8ed142895f05e792852bfd8a7ed00b49dfa0672f702cd99e1f15462d","04b9304cf599d31ae15b912fcddb3ea62db242e57a25511ba74422d886715c9f"],"ts":1793275883,"cid":"poa-mainnet-1","sig":"oGgTczt7K44wJMbYrJmzKqLmyqfMRMYthj8dj7Dv4ZMhxuT2KCEouMT4eVuQwLvgVNEe9pTxxRuNddKc56TJqs7"},"checkpointed":{"height":236055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:15:49.924Z","checkpoint_height":236055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
