Anatoly Yakovenko, co-founder of Solana, explains how Solana’s Alpenglow upgrade will quietly reshape MEV. To be exact, this modification will modify the consensus incentives related to slot execution timings to change the way validators deal with block builders. Not a complete redesign of the fast network, but a step in the right direction for Solana.
Solana’s Alpenglow upgrade also creates additional incentive for delaying block production. If a slot is delayed beyond the timeout, leaders will lose all of the remaining slots in their assignment. This is intended as a stopgap for avoiding the type of strategic stalling that occurs in other protocols to gain more MEV capture.
Solana’s Alpenglow Upgrade and the New Economics of Delay Costs
The penalty structure makes the costs of delay highest in the first slot of a leader’s schedule and lowest in the last slot. The reason delays early on cost more (for opp cost) is that you forego more potential block rewards and MEV, whereas the late delays are less costly (on opp cost).

This gradient also might disincentivize last-minute reordering games, for example, and shift MEV extraction toward more transparent and time-sensitive strategies, mostly throughout Solana’s DeFi and NFT markets.

Validator Resilience vs Timing Risk: Alpenglow’s Tradeoffs
Solana’s Alpenglow upgrade may make the network more robust for validators and mitigate some of the uncertainty in slot timing. Builders and searchers will have to modify MEV bots and bundling algorithms to account for the altered timing risk. The main issues would be in readjusting latency optimization and making sure that smaller validators are not unduly impacted by high timeout costs. Earlier, the update was expected, but currently it has come into action.

Solana’s Alpenglow Upgrade Realigns
Solana’s Alpenglow upgrade isn’t about removing MEV on Solana; it’s realigning its economics at the consensus level. By inserting costs to delays and time-sensitivity into consensus, developers (and validators) will soon have a new approach to incentivize fairly produced blocks and a more stable Web3 trading environment. Developers and validators, take note – when implemented, watch how these nuanced consensus changes play out in reality, scaling MEV, throughput, and decentralization.
