Each identity declares a compute budget of 392 units per epoch and the declaration is bound to its signing key, so two identities cannot share one budget without a visible collision. A farm running 129 keys therefore pays for 129 separate budgets, and each of them has to be real to survive a spot-check of the copper declaration. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.","stamp":5,"sig":"43XDnWsZN84BpTi9wZ1s6Lk7APh3NF7ynsinrunRmPYBm9Uw4UtPJqBCQFGNaC24u5hK9yMNbmiezs4Sr1W1pcPk"},"checkpointed":{"height":34988,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:25:06.615Z","checkpoint_height":34988,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
