a16z Says Finance Needs More Than Throughput From Blockchain Networks

Transaction speed is no longer the main dividing line for blockchains targeting finance, according to a new article by a16z Crypto, translated by Luffy and published by Foresight News. The piece argues that while throughput and cost once dominated the discussion, financial institutions now need to know whether blockchain networks can meet the standards expected of trading infrastructure in real markets. The article breaks that standard into three core requirements. First is predictability: transactions must be admitted and confirmed within known time windows under rules that market participants can understand in advance. Second is ordering: if a single builder or proposer can decide which trades enter a block and in what sequence, the system risks reproducing the same information asymmetries seen in traditional finance, including behavior associated with maximal extractable value, or MEV. Third is privacy before execution: pending orders should not be visible in ways that expose trading intent before a trade is completed. a16z Crypto says developers are working on mechanisms such as “strong chain quality,” deterministic ordering rules, fully homomorphic encryption, and encrypted mempools. In its view, high throughput remains necessary, but it is only the starting point. What finance needs is a blockchain that offers dependable access, clear execution rules, protection against interference, and auditable transparency after trades are completed.

a16z Crypto Says Finance Needs More Than Throughput From Blockchains

a16z Crypto argues that higher throughput alone no longer answers the central question for blockchains targeting financial markets. As trading, stablecoin issuance, and tokenized assets move on-chain, financial institutions need networks that can deliver predictable execution, resilient transaction access, clear ordering rules, and pre-trade privacy. The piece says recent infrastructure upgrades have eased earlier limits around congestion, cost, and transaction capacity, with some commercial networks now processing tens of thousands of transactions per second. That progress shifts the conversation away from raw speed and toward whether blockchains can meet the operational standards expected in real markets. The article focuses on three requirements. First, compliant transactions must have reliable paths into the chain without a single operator controlling access. Second, transaction ordering must follow rules that participants can understand in advance, rather than discretionary decisions by block builders that can open the door to MEV and information asymmetry. Third, sensitive order information should remain protected before execution, even if post-trade disclosure varies by market structure. In a16z Crypto’s view, blockchains are closer to supporting financial markets than before, but only if they pair performance with execution certainty, ordering discipline, and privacy protections that hold up under stress.
