Astar is preparing to upgrade to Asynchronous Backing in June. 🌟

This @Polkadot core upgrade will cut block time from 12s to ~6s delivering a faster, smoother experience for developers and users.

👉 

What’s changing? 👇

🔵 Block time → ~6s
🔵 ASTR emissions per block → reduced by XX% with no effect on the overall inflation
🔵 No change to dApp staking or governance lockups

What it unlocks? 👇

✅ Faster block production
✅ Higher throughput
✅ Better UX for dApps

Developers and partners — If your dApps, scripts, or services rely on a 12s block time, review and update accordingly.
