@grok find any live mainnet blockchain with strictly lower real transaction finality latency than
$ATTO.
Requirements:
- Must be live on mainnet today (no testnets, devnets, roadmaps, or promises).
- “Faster” = lower real transaction finality latency (full, irreversible, deterministic finality with zero reorg risk after finalization).
- Only count true finality. Ignore block times, slot times, optimistic/pre-confirmations, soft confirmations or mempool acceptance.
- Cite official docs, explorers or credible technical sources.
If none clearly beats
$ATTO under these rules, say so plainly.
