V9 Mainnet Upgrade

Medium7.0

◆ Description

Celestia V9 goes live on Mainnet, halving block time from 6 to 3 seconds for faster confirmations and more blockspace across networks built on Celestia.

◆ Why it matters

Celestia's V9 mainnet upgrade halves block time to 3 seconds, doubling blockspace for networks built on the data availability layer. This is a concrete, live performance improvement at the core of TIA's value proposition as a high-throughput DA network. The upgrade has been on the roadmap and largely anticipated, so the re-rate is material but contained rather than thesis-changing.
