Ushuaia Live

◆ Description

The 21st protocol upgrade activates with higher DAL bandwidth, dynamic DAL attestation lag, and rollup-aligned PVM upgrades at 1:16 AM UTC.

◆ Why it matters

This mainnet upgrade improves Tezos' data availability and rollup execution path, which supports the chain's scalability narrative and gives active followers a concrete reason to update expectations. The market impact is real because the changes go live on-chain, but it stays contained since the upgrade is an incremental infrastructure step rather than a direct shift in XTZ demand or the network's valuation thesis.
