Cosmos SDK chains access historical state via ABCI queries keyed on module + KV-store, which does not map onto the flat `eth_getBalance(address, height)` probe cleanly.","No cross-provider hash quorum on this chain at v1. Tendermint `status` does return `latest_block_hash` on the same block the height is reported for, so a quorum check is technically feasible, but the initial Osmosis add-on ships without it to keep the reliability change surface small; the hash normalisation across Cosmos chains will be validated before wiring bench 083 here.","Chain scope: every query on this page is pinned to `chain=\"osmosis\"`.
