ARK Pushes Back on a16z: Public Blockchains Are Winning TradFi Adoption
ARK Invest says public blockchains are already outpacing private blockchain projects in traditional finance. On Wednesday, ARK research director Lorenzo Valente challenged a16z crypto’s claim that banks and asset managers will adopt blockchain through permissioned systems instead of decentralized finance (DeFi). That is the split. For crypto investors, the outcome could determine where tokenized assets eventually land. Why take the public-chain argument seriously? Because Ethereum’s total value locked (TVL) rose 12% in Q1 2024. My take: that does not settle the debate, but it makes ARK’s position harder to dismiss.
Valente’s disagreement with a16z comes down to a simple question: Will TradFi use open DeFi networks or build private ones? A day earlier, a16z crypto argued that financial institutions are adopting pieces of blockchain technology, not DeFi itself. Banks and asset managers want systems fitted to their compliance requirements and operating rules. A16z expects them to create “programmable financial infrastructure” using tokenization and atomic settlement. Access would remain restricted; institutional control would remain intact. Most commentary treats this as a technical choice. That’s only half right. It is also a fight over where the money goes. Enterprise blockchain products could pull capital away from DeFi tokens, and protocols counting on direct institutional use would take a hit.
Valente cited the growth of tokenized assets on Ethereum and other open networks as evidence that public chains are already ahead of private projects. BlackRock’s work on tokenized funds is one concrete example. Institutions are not necessarily walking onto public networks without restrictions; they are bringing their own compliance systems with them. The distinction is crucial. Public chains offer shared liquidity plus compatible applications, whereas private networks often operate in isolation. Why does that matter? Because capital can move and interact more easily on established public infrastructure. To my eye, this is Valente’s strongest point: those advantages could draw more institutional capital to public networks over time.
Valente also thinks crypto companies such as Circle and Coinbase are in a better position to build new financial infrastructure than established banks. I’ll be honest: that sounds bold until you look at Coinbase’s institutional expansion and the market’s response. COIN shares are up 25% year to date. Investors appear to believe Coinbase can connect traditional markets with crypto. But software alone will not decide this. Control is the catch. Counter to the usual disruption story, regulators may matter more than product speed here. SEC pressure could determine how freely Coinbase and Circle can compete, along with similar firms.
Sentora co-founder Jesus Rodriguez expects institutions to use DeFi infrastructure with enterprise controls layered on top. Adoption may be slow. Firms could keep their existing compliance systems and custody arrangements while using DeFi’s underlying infrastructure. Honestly, that sounds more likely than banks rushing into unrestricted DeFi. Yes, it softens the clean public-versus-private divide — and that may be the point. Such a model would still demonstrate the value of DeFi’s underlying tools, even if institutions initially use them within stricter limits.
What this means
ARK and a16z disagree about how institutional money will enter crypto. The stakes are real. If ARK is right, tokenized assets should keep growing on public networks such as Ethereum, potentially supporting ETH and other Layer 1 tokens through added demand. It would also show that financial institutions can use open networks when suitable compliance controls are in place. If a16z is right, banks and asset managers may build a separate blockchain market under their own control — one that competes with DeFi for capital. My take: investors are not choosing between two versions of the same trend. They are choosing between public crypto networks and systems controlled by financial institutions.
Investors can watch real-world asset (RWA) tokenization on Ethereum and other public chains for signs that institutions are moving on-chain. This is the cleaner test. If a major bank or asset manager announces a tokenization project on a public chain, ETH could make another run at the $4,000 resistance level. Slow adoption would weaken the near-term case for institutional DeFi use; a clear preference for private networks would do the same. Is watching SEC decisions overkill? No, because rulings involving stablecoins and tokenized securities could make public networks easier for institutions to use if the rules become clearer. I would watch those decisions alongside actual project announcements over the next few quarters. Right now, ARK and a16z both have plausible arguments. The market has not picked a winner.
