Alpenglow is not on mainnet yet. The community test cluster is where validator operators evaluate the new consensus design under real-world conditions before any broader rollout.

What Builders Should Do Right Now
1. Build against 150ms finality assumptions
If you're designing application architecture today that will ship in Q4 2026, model your UX and confirmation flows against 150ms rather than 12.8 seconds. Don't design for the current network if your launch is after mainnet activation.
2. Audit your RPC infrastructure for throughput
