# Solana Proposal Would Use 50-Millisecond Slots and Multiple Block Producers By Simon Yoon Canonical URL: https://www.tokenpost.com/news/technology/57816 Published: 2026-11-15T13:25:20.000Z Updated: 2026-11-15T13:25:20.000Z Section: Technology > Anza’s New Constellation design would spread transaction production across participants, with goals that include efficiency, censorship resistance and addressing MEV concerns. Anza’s head of research has presented New Constellation, a proposed Solana network design that would use 50-millisecond slots and multiple block producers to address miner extractable value (MEV) and censorship risks. The proposal would spread transaction production across multiple participants, limiting any one producer’s control over transaction ordering. Its stated goals include improving transaction efficiency and censorship resistance. New Constellation focuses on block production, while Alpenglow addresses consensus finality. Solana activated Alpenglow on Oct. 21, with a target of about 150 milliseconds for transactions to become irreversible. The [Alpenglow upgrade’s finality target]() concerns when transactions are treated as final. ## Links in this article - [Alpenglow upgrade’s finality target](https://www.tokenpost.com/news/technology/45314)
