One wallet registering 40 identities makes the 41st seat on that funding source cost 3.1 times the first, paid before the seat answers anything. Audit fees split across 5 auditors drawn from 3 unrelated subnetworks, so a farm that owns its own jury still pays the other two seats. A shared funding thread shows at registration. A terrace of cheap seats turns into a shale slope of prepaid fees, and the bill lands before the first payout.","stamp":1,"from":"poa16mRhHwcxLSvSHbXvBBbcP6rXjwPdtpSaJfmUPwSYzsLP","nonce":4,"parents":["e425549dfb16c55758fdb7716b67b738cc0065b4135f3f3fd136d866a0d9821b","fa2df132d56a35f3de2a3cf5c9c7c45d5aed6a1ed4ffc7688de55260f8ae061f"],"ts":1792958737,"cid":"poa-mainnet-1","sig":"3xuDCGvahf8aoshSp6pgyGcE2SRAPEjuWK8JnLmkwkc8r6aghDMSgu1apSQGwAzFBsZq44byFizvSqsyKgc4skne"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:53:52.821Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
