The IOTA mainnet has completed a major consensus upgrade, switching its protocol to Starfish in a move designed to boost network performance and resilience. The upgrade went live on April 28, 2026, according to a project announcement.
"The IOTA Mainnet just got a major consensus upgrade. Starfish is now live," the IOTA team said in a post on X, formerly known as Twitter.
The Starfish upgrade introduces a new consensus mechanism that allows the network to keep progressing even when some validator nodes are lagging. According to the project's technical documents, this change lets lagging nodes recover in parallel, preventing them from stalling overall network consensus. The primary benefits are expected to be improved liveness, greater resilience under network stress, and a potential increase in effective transaction throughput. This technical improvement is similar in scope to the regular upgrades performed on the Ethereum network to enhance its scalability and security.
For the IOTA (IOTA) token, the successful implementation of a more robust and predictable consensus layer is a significant milestone. It could strengthen developer and institutional confidence in the protocol, making it a more attractive platform for high-value enterprise applications, particularly in IOTA's target sectors of global trade and logistics. Analysts believe that reducing perceived protocol risk is a key factor in the long-term valuation for base-layer crypto assets.
