ARK pushes back against a16z’s TradFi-not-DeFi claim

ARK pushes back against a16z crypto’s claim that traditional finance wants permissioned blockchain rather than DeFi. ARK Invest’s Lorenzo Valente argued public chains already beat private initiatives, citing tokenized assets on open networks, while Sentora’s Jesus Rodriguez said institutions will adopt DeFi rails with compliance layers.

Key Takeaways

• ARK Invest research director Lorenzo Valente disputed a16z crypto’s view that TradFi will favor permissioned blockchain over DeFi.
• Valente said public blockchains have already outperformed private initiatives, pointing to tokenized assets on Ethereum and other open networks.
• a16z crypto argued banks and asset managers will borrow blockchain primitives while keeping systems permissioned and institutionally controlled.
• Sentora co-founder Jesus Rodriguez said institutions are likely to use DeFi infrastructure with compliance, custody and enterprise controls on top.
• Valente argued crypto-native firms such as Circle and Coinbase are best placed to build next-generation financial infrastructure.

Why did ARK push back against a16z’s TradFi thesis?

The clash centers on how traditional finance will enter crypto rails. According to Cointelegraph’s report, ARK Invest’s director of research rejected the idea that incumbents will stop at closed, permissioned chains.

In a Wednesday X post, Lorenzo Valente said public blockchains have already outperformed private blockchain initiatives. He cited the growth of tokenized assets on Ethereum and other open networks as evidence that open rails are winning where it counts.

Valente also cast doubt on the notion that legacy banks will lead the rebuild. He said crypto-native firms such as Circle and Coinbase, rather than incumbent financial institutions, are best positioned to build the next generation of financial infrastructure.

That stance is a direct challenge to the “blockchain yes, DeFi no” framing. It also feeds a wider debate tracked across Fintech & Crypto Alerts on BlasterPost: whether institutions will truly open up, or merely wrap familiar controls around selective tech.

What did a16z crypto actually argue?

A day earlier, a16z crypto argued that traditional financial institutions are not embracing DeFi. Instead, the firm said they are selectively adopting blockchain technology that fits existing compliance, governance and operational requirements.

In its X post, the venture firm said banks and asset managers will build “programmable financial infrastructure.” That stack would borrow blockchain primitives such as tokenization and atomic settlement, while remaining permissioned and institutionally controlled.

In short, a16z’s thesis separates useful blockchain features from open, permissionless DeFi markets. The claim is that TradFi wants the tooling, not the open-finance model.

How does Sentora frame institutional DeFi adoption?

Sentora co-founder Jesus Rodriguez also pushed back against a16z’s thesis. He said institutions are likely to adopt DeFi’s underlying infrastructure while layering compliance, custody and other enterprise controls on top.

That middle path still puts DeFi rails at the core. It suggests controls can sit above open infrastructure, rather than replacing it with fully private chains.

Cointelegraph summarized ARK’s dispute as arguing that institutions will increasingly rely on DeFi rails, not just permissioned blockchain infrastructure. The exchange leaves a clear market question: will tokenized finance scale on public networks, or behind institutional walls?
