For many years, blockchain infrastructure has competed on one metric above almost all else: performance. Faster blocking times, lower fees, and higher throughput have become the standards by which networks are judged. Solana has excelled on these fronts, proving that high-performance blockchains can support everything from decentralized exchanges to payment applications and consumer-facing products.
As the ecosystem continues to mature, a different conversation is beginning to take shape. Instead of asking how quickly transactions could be processed, developers and validators began asking whether the transaction markets themselves were operating as efficiently as possible.
Much of the discussion centers around system flow. Each pending transaction carries information that can influence trading strategies, arbitrage opportunities and block building. Access to this information is becoming increasingly valuable, but it is not always evenly distributed across the ecosystem.
This has implications beyond traders. Validators rely on transaction fees and revenues associated with EVs to boost their economies, developers need predictable infrastructure to build applications, and users ultimately benefit when transaction markets remain competitive rather than concentrated among a few participants.
Increased transparency could improve incentives across the board. Wider access to transaction flow encourages more validators to compete, which may increase competition for block space while improving validator revenue. Rather than relying on special relationships or ownership guidance, market participants compete on the quality and efficiency of execution.
Some infrastructure projects are now based on this idea. Flowra is developing an open order flow auction that aims to create a more open market for transaction flow while allowing validators to customize block construction through programmable block policies. The goal is not just to increase visibility, but to give auditors more flexibility over how they participate in Solana’s transaction economy.
“We believe it is possible to achieve full transparency and auditability while also protecting the grid from malicious MEV,” said Harry, CEO of Flowra. “At the same time, we recognize that MEV cannot be completely eliminated. They are a natural consequence of how blockchain works, and attempts to completely suppress them often push them into less visible forms rather than removing them. Not all MEV are harmful. Atomic arbitrage, filtering, and back-running strategies often referred to as ‘ethical MEV’ play an important role in improving market efficiency and maintaining balance within the ecosystem.”
It remains to be seen whether this becomes the mainstream trend for blockchain infrastructure. But the conversation itself reflects how much the industry has evolved. Speed and scalability are no longer enough on their own. As institutional involvement increases and blockchain networks become more economically important, transparency is a feature that developers, auditors, and users are beginning to value equally.
This shift extends beyond transparency alone. “Network performance is increasingly table stakes,” Harry said. “The next axis of competition is shifting toward who gives validators more meaningful choices and better economics.” Through the Programmable Block Policy (PBP), Flowra aims to give auditors greater autonomy over cluster configuration, allowing them to select policies that align with their operational, economic, or compliance requirements rather than simply acting as an execution node.
Looking to the future, Harry believes Solana’s roadmap could make transparent order flow infrastructure even more important. “The roadmap to multiple concurrent bidders means that no single leader controls which block is completed, which naturally makes it more difficult to implement malicious MEV strategies at the protocol level,” he said. “But this architectural shift also raises a new question: In a world with so many simultaneous proposers, who coordinates the flow of the system across them all?” In his view, the “open and unified order flow layer” is becoming increasingly important as transaction markets grow more sophisticated and institutional participation continues to expand.
The next phase of blockchain infrastructure may not be determined by who builds the fastest network, but who builds the most open and competitive markets around it.
