Solana Fairness Upgrade Stalls as Block Producers Retain Transaction Ordering Power
(4 days ago) · 1 source · Summarized by CryptoBipto
Solana's effort to create a fairer transaction ordering system has not yet achieved its goals, as block producers continue to have discretion over which transactions are included in blocks and in what order. The issue highlights ongoing challenges with miner/validator extractable value on the network.
WHY IT MATTERS
When you submit a trade on a blockchain, someone has to decide the order in which transactions are processed — much like a cashier deciding who gets served first in a line. On Solana, the validators who build blocks have this power. The concern is that they can use it to cut in line or let others cut in line for a fee, which can cause regular users to get worse prices on their trades. This is called MEV, or maximal extractable value. Solana has been trying to make this process fairer, but so far, validators still have a lot of control over ordering. For newcomers, this is important because it affects whether the price you see when you place a trade is the price you actually get.
