For years, blockchain infrastructure has competed on one metric above almost everything else: performance. Faster block times, lower fees, and higher throughput have become the benchmarks by which networks are judged. Solana has excelled on those 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, however, a different conversation is starting to take shape. Rather than asking how quickly transactions can be processed, developers and validators are beginning to ask whether transaction markets themselves are operating as efficiently as possible.
Much of the discussion centers around orderflow. Every pending transaction carries information that can influence trading strategies, arbitrage opportunities, and block construction. Access to that information has become increasingly valuable, yet it is not always distributed evenly across the ecosystem.
This has implications beyond traders. Validators rely on transaction fees and MEV-related revenue to strengthen their economics, developers need predictable infrastructure to build applications, and users ultimately benefit when transaction markets remain competitive rather than concentrated among a handful of participants.
Greater transparency could improve incentives across the board. Broader access to transaction flow encourages more searchers to compete, which can increase competition for blockspace while improving validator revenue. Instead of relying on private relationships or proprietary routing, market participants compete on execution quality and efficiency.
Some infrastructure projects are now building around that idea. Flowra is developing an Open Orderflow Auction that aims to create a more open marketplace for transaction flow while allowing validators to customize block construction through Programmable Block Policies. The objective is not simply to increase visibility, but to give validators 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 network from malicious MEV,” said Harry, CEO of Flowra. “At the same time, we recognize that MEV cannot be completely eliminated. It is a natural consequence of how blockchains operate, and attempts to suppress it entirely often push it into less visible forms rather than remove it. Not all MEV is harmful. Atomic arbitrage, liquidations, and back-run strategies often referred to as ‘ethical MEV’ play an important role in improving market efficiency and maintaining balance within the ecosystem.”
Whether this becomes the dominant direction for blockchain infrastructure remains to be seen. But the conversation itself reflects how the industry is evolving. Speed and scalability are no longer enough on their own. As institutional participation increases and blockchain networks become more economically significant, transparency is becoming a feature that developers, validators, and users are beginning to value just as highly.
That shift extends beyond transparency alone. “Network performance is increasingly becoming table stakes,” Harry said. “The next axis of competition is shifting toward who gives validators more meaningful choices and better economics.” Through Programmable Block Policy (PBP), Flowra aims to give validators greater autonomy over block composition, allowing them to define policies that align with their own operational, economic, or compliance requirements rather than simply acting as execution nodes.
Looking further ahead, Harry believes Solana’s own roadmap could make transparent orderflow infrastructure even more important. “The roadmap toward Multiple Concurrent Proposers means no single leader controls which block gets finalized, which naturally makes it harder to execute malicious MEV strategies at the protocol level,” he said. “But that architectural shift also raises a new question: in a world with multiple concurrent proposers, who coordinates orderflow across all of them?” In his view, “an open, standardized orderflow layer” becomes increasingly critical as transaction markets grow more sophisticated and institutional participation continues to expand.
The next phase of blockchain infrastructure may not be defined by who builds the fastest network, but by who builds the most open and competitive markets around it.
