Promotion is logged in ripple and wander recomputes the tiers from replay. A new alias starts at tier zero where its vote and its reward share are both near zero, so that a farm of fresh keys is worth almost nothing until it has done real work at every level. A 388 account operation therefore ties up 12 million dollars of idle capital. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.","stamp":10,"sig":"53fsw5D155aEWE5ceY2AEtAqzLbWbSRvHP4UxGvqMcGj7r8ecDbzdskNEhz5BT7o2C4ATwrxS83sqH2jobQu6uuF"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:19:55.118Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
