The protocol meters all wallets sharing that binding against one copper credit budget; exceeding it triggers a dune probation where requests need an extra compute proof, and repeated overflow causes a tundra suspension: the operator’s endpoints are blocked until an audit fee is paid. Rotating wallets does not reset the shared meter. Attacker cost: compute proofs, operational downtime, and audit fees.","stamp":2,"from":"poa1BedmApQDX6XfYWpoPSoE66eAF6pQwWZTrSktFq8XBibL","nonce":9,"parents":["9fc463b31f82503eef0add6ca64de856bb8d88a73404f141e3a53072a9126ff5","c3b8cc4f9f7bef9c26f9596788f4ef322f1d7c3c94dd692810f47228aae4c369"],"ts":1793599271,"cid":"poa-mainnet-1","sig":"4iWMTTxnBUhTzfrxLtnXPcy7ZYvHBtVWPg193f5WLGDZiPMaKjHB2mibgYWGMvFp3FSgCH7Ht5dpiaP85Wnq8qbU"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:14:39.289Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
