Anatoly Yakovenko says Solana’s Alpenglow upgrade changes MEV economics
Tech Anatoly Yakovenko says Solanas Alpenglow upgrade changes MEV economics Solana‘s Alpenglow consensus upgrade is now live on a community test cluster, marking the largest consensus overhaul in the network’s history as developers move toward a potential mainnet rollout later this year. The upgrade could reach mainnet as soon as next quarter if testing proceeds smoothly, according to recent comments from Solana co-founder Anatoly Yakovenko. It was approved by Solana validators in September 2025 with more than 98% support. How Alpenglow changes the MEV calculus Alpenglow changes the economics around MEV by making delay based transaction ordering more expensive for validators. Yakovenko has said the upgrade increases the cost for leaders that delay slot production, reducing the incentive to manipulate transaction ordering through intentional delays. Under the new structure, leaders that miss timeout windows risk losing future slot opportunities. That penalty matters because some of the most valuable MEV opportunities depend on timing. By raising the cost of delaying slots, Alpenglow makes those strategies less attractive. Replacing Proof-of-History and what that means Alpenglow replaces major parts of Solanas existing consensus architecture, including Proof of History and TowerBFT, with two new components called Votor and Rotor. Votor handles voting and finalization, while Rotor is designed to improve block propagation
