It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.","stamp":1,"sig":"6132uXQj7KMr9goMYXtj3XTdGgHABMBn6vACiEaBgbMSd1ZUNzGujpuLcwNvhD1DdEpr1Ra3j3aDqTAGga13tXur"},"checkpointed":{"height":143436,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:01:20.645Z","checkpoint_height":143436,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
