The debate over how traditional finance will integrate blockchain technology has intensified. ARK Invest’s director of research, Lorenzo Valente, publicly disputed a16z crypto’s claim that institutions will adopt permissioned blockchain infrastructure rather than decentralized finance (DeFi). In a post on X (formerly Twitter), Valente argued that public blockchains have already demonstrated superior performance compared to private blockchain initiatives, pointing to the rapid growth of tokenized assets on Ethereum and other open networks.
Valente’s comments come a day after a16z crypto published its own analysis, which asserted that traditional financial institutions are not embracing DeFi but are selectively adopting blockchain technology that fits their existing compliance, governance, and operational needs. According to a16z, banks and asset managers will build “programmable financial infrastructure” that borrows blockchain primitives such as tokenization and atomic settlement, while keeping systems permissioned and institutionally controlled.
The core disagreement
The disagreement between ARK and a16z highlights a fundamental divide in the crypto industry. On one side, proponents of DeFi argue that open, permissionless systems are more innovative, efficient, and ultimately better suited for global finance. On the other, advocates of institutional blockchain adoption claim that regulated entities require privacy, identity verification, and legal compliance that only permissioned systems can provide.
Valente struck back by citing the success of tokenized real-world assets on public blockchains. For example, the total value of tokenized US Treasury products has surged past $1 billion on Ethereum, driven by offerings from companies like Ondo Finance and BlackRock’s Buidl fund. These products rely on Ethereum’s public infrastructure but add institutional-grade custodianship and compliance layers.
“Public blockchains are winning,” Valente wrote. “Private chain experiments have largely failed to gain traction. The next generation of financial infrastructure will be built by crypto-native firms, not incumbents.” He specifically mentioned Circle, the issuer of USDC stablecoin, and Coinbase, the leading US crypto exchange, as examples of companies that are best positioned to lead this transformation.
a16z’s perspective
a16z’s argument is rooted in the realities of traditional finance. Banks and asset managers operate under strict regulatory frameworks that require know-your-customer (KYC) and anti-money laundering (AML) controls. Permissioned blockchains allow them to maintain control over who can participate in a network, which is essential for legal compliance.
The venture capital firm emphasized that institutions are not rejecting blockchain technology altogether, but rather adopting it in a way that preserves their existing business models. By using programmable, permissioned ledgers, they can achieve efficiencies like atomic settlement and tokenization without exposing themselves to the risks of open DeFi, such as smart contract vulnerabilities or unregulated trading.
a16z also pointed to initiatives like JPMorgan’s Onyx platform and the Canton Network as examples of successful permissioned blockchain deployments. These projects handle significant transaction volumes while maintaining institutional standards.
Sentora co-founder adds nuance
Sentora co-founder Jesus Rodriguez weighed in on the debate, offering a middle-ground perspective. He argued that institutions are likely to adopt DeFi’s underlying infrastructure—such as smart contracts and composability—while layering compliance, custody, and other enterprise controls on top. This hybrid approach could allow traditional finance to benefit from innovation without sacrificing regulatory requirements.
Rodriguez noted that many institutional DeFi projects are already exploring this path. For instance, the Tokenized Asset Coalition, which includes companies like Coinbase, Circle, and Goldman Sachs, promotes open standards for tokenized assets while advocating for regulatory clarity. Such efforts suggest that the line between permissioned and permissionless systems may blur over time.
Historical context and industry trends
The tension between open and closed blockchain systems is not new. In the early 2010s, financial institutions experimented with private blockchains, such as R3’s Corda and Hyperledger Fabric. However, these efforts often struggled to achieve network effects and interoperability. Meanwhile, public blockchains like Ethereum have attracted vast developer communities, leading to rapid innovation in DeFi, NFTs, and tokenization.
A 2023 report by the Bank for International Settlements found that central banks are exploring both permissioned and permissionless models for central bank digital currencies (CBDCs). But for commercial applications, the trend appears to be shifting toward public blockchains with added compliance layers. For example, the Depository Trust & Clearing Corporation (DTCC) completed a pilot using a public blockchain for clearing and settlement, demonstrating that institutional requirements can be met on open networks.
Tokenization of real-world assets is perhaps the clearest example of this trend. The total market for tokenized assets could reach $16 trillion by 2030, according to some estimates. While early projects like the Facebook-led Libra (now Diem) pursued permissioned models, more recent success stories—such as Ondo Finance, Matrixdock, and BlackRock—have chosen Ethereum or other public chains.
Why this matters
The outcome of this debate will shape the future of financial infrastructure. If ARK’s view prevails, we may see a gradual shift toward DeFi-based systems that incorporate institutional controls. If a16z is correct, traditional finance may build parallel permissioned networks that coexist with public blockchains but never fully integrate with DeFi.
Valente’s confidence in crypto-native firms rests on their ability to build compliance tools directly into their products. Circle, for example, has developed USDC with built-in compliance features that allow regulated entities to use stablecoins without violating sanctions. Coinbase offers institutional custody and staking services that bridge the gap between DeFi and traditional finance. These companies are already handling billions of dollars in transactions and are increasingly partnering with legacy institutions.
As the crypto market matures, the distinction between TradFi and DeFi may become less relevant. What matters is not whether a system is permissioned or permissionless, but whether it solves real problems for users and meets regulatory standards. The debate between ARK and a16z is a healthy sign of an industry wrestling with its own evolution.
The discussion also highlights the importance of regulation. Clearer rules around stablecoins, tokenized assets, and decentralized exchanges could accelerate adoption by giving institutions the confidence they need to engage with DeFi. The United States and European Union are both working on comprehensive crypto legislation, which could tip the scales in favor of one model or the other.
In the meantime, investors, developers, and institutions will watch closely as both approaches play out. The coming years will reveal whether traditional finance truly embraces blockchain on its own terms or if the open ethos of DeFi eventually wins out.
