Mina Protocol announces Mesa mainnet upgrade for September 3, featuring 90-second block times and increased zkApp throughput.
Tech & Launches ·
Mina Protocol announced Mesa, a mainnet upgrade scheduled for September 3, 2026, that will reduce block times to 90 seconds and expand zkApp throughput capacity. The upgrade also aims to establish a more streamlined process for rolling out future protocol changes. The upgrade was confirmed via the protocol's official channels.
Mesa represents an incremental optimization of Mina's consensus and execution layers. Shorter block times reduce latency for transaction finality, while higher zkApp throughput allows more zero-knowledge application transactions to settle per unit time. These mechanics could strengthen Mina's position among protocols emphasizing privacy and zero-knowledge computation.
What remains unclear is whether the 90-second target will be sustained under peak network load, how zkApp throughput scales in practice relative to current capacity, and what specific changes to the upgrade pathway will ease future iterations. Market adoption of zkApp infrastructure following the upgrade is also an open question.
