Why BlackRock and Other Major Institutions Pay Attention to Blockchain Tech: Aptos CBO Solomon Tesfaye Interview

The tokenization narrative is not only growing, but it’s also evolving. While early conversations focused on whether the real-world asset sector could move on-chain, institutions are now asking a very different question: can blockchain infrastructure support financial markets at scale?

This shift is becoming increasingly visible across multiple networks, including Aptos. Securitize-related assets have reportedly surged 632% in June to reach $276 million. As major products such as BlackRock’s BUIDL fund expand on the network, Aptos is positioning itself as infrastructure built for continuous settlement, institutional-grade financial activity, liquidity, and more.

In the following interview, Solomon Tesfaye discusses the rapid growth of tokenized assets on the platform, the infrastructure institutions actually care about, and why the next phase of blockchain adoption may be driven by the convergence of both markets and machines.

Securitize-related assets on Aptos have reportedly grown 632% this month to $276 million. What does that kind of growth tell you about how institutions are approaching onchain markets right now?

The percentage growth is interesting, but what matters more is where activity concentrates once assets actually live.

Securitize issues and manages tokenized real-world assets for institutional sponsors including BlackRock and Apollo, and Aptos is one of the networks those assets can run on. Once that happens, issuance is no longer the main focus. The focus shifts to how those assets function inside real financial systems.

That is where the shift toward “markets” becomes visible. Settlement, collateral movement, and integration with trading and payment workflows all start to matter more than tokenization itself. On Aptos, those flows sit on infrastructure designed for continuous, high-frequency activity rather than static issuance.

What we’re seeing across the industry is a transition from proving assets can be tokenized to determining whether blockchain infrastructure can support real financial activity at scale. The networks that benefit are increasingly the ones capable of supporting continuous market activity, not just issuance.

What do you think is driving the recent increase in Securitize-related activity on Aptos specifically?

As assets become active in markets, operational requirements become much more important.

Tokenized funds are not static holdings. They move through settlement processes, collateral workflows, liquidity venues, and treasury operations. That creates a very different infrastructure requirement than simply recording ownership on-chain.

Aptos has now processed more than 5 billion transactions, maintains approximately 30-millisecond block times, and has delivered 99.99% uptime since mainnet launch. Those are the types of operational characteristics institutions evaluate because they reduce uncertainty around execution.

What we’re seeing across the industry is activity increasingly concentrating on infrastructure that has already demonstrated reliability under real-world conditions rather than theoretical performance.

BlackRock’s BUIDL fund, tokenized by Securitize, expanded to Aptos alongside several other chains, bringing one of the largest tokenized fund products into the Aptos ecosystem. What does that signal about Aptos’ position in the institutional RWA market?

The signal is that infrastructure choices are being made at a much more technical and operational level. BlackRock is not selecting chains for visibility. It is evaluating whether infrastructure can support regulated financial products operating at scale with predictable settlement and performance.

The expansion of BUIDL through Securitize onto Aptos reflects that evaluation process. It signals confidence that Aptos meets the requirements for institutional-grade financial products, particularly around consistent performance, reliability, and the ability to support continuous market activity.

More broadly, it reinforces Aptos’ positioning in the RWA market as infrastructure designed for high-frequency, always-on financial systems where tokenized funds, settlement flows, and collateral movement need to operate without friction at scale.

The takeaway is that institutional adoption is increasingly converging on infrastructure capable of supporting real financial market operations on-chain, not just tokenization experiments.

A lot of the discussion around tokenization still focuses on future potential, including tokenized stocks and other multi-trillion-dollar markets. What are tokenized real-world assets actually being used for onchain today?

Today, adoption is concentrated in relatively familiar financial instruments.

Money market funds, Treasury products, private credit, and short-duration fixed income assets account for much of the activity. Examples include products such as BlackRock’s BUIDL and Franklin Templeton’s BENJI.

What’s notable is that institutions are not necessarily starting with entirely new asset classes. They’re starting with assets where operational improvements can be realized immediately through faster settlement, reduced reconciliation, improved collateral mobility, and greater programmability.

In many ways, the first wave of tokenization is less about changing what assets are and more about changing how financial infrastructure operates around those assets.

For tokenized assets to move from early adoption to institutional scale, what infrastructure matters most: speed, settlement finality, compliance tooling, identity, liquidity, custody, interoperability, or something else?

Every component matters: compliance, custody, identity, liquidity, interoperability, and settlement.

But reliability is the prerequisite.

Institutions can solve many operational challenges. What they cannot solve is infrastructure that behaves inconsistently under load. Financial systems operate continuously, so sustained performance matters far more than peak performance.

Once reliability is established, the rest becomes an integration challenge across custody, compliance, trading, and liquidity.

Increasingly, institutions are evaluating blockchain infrastructure the same way they evaluate traditional financial infrastructure: based on resilience, predictability, and uptime.

Aptos has often positioned itself around performance, scalability, and reliability. How do those technical priorities translate into real advantages for institutions issuing or managing tokenized assets on-chain?

The best infrastructure is infrastructure that fades into the background.

Institutions are not trying to optimize for blockchain activity. They are trying to operate financial products efficiently and predictably. Performance only matters if it translates into operational certainty.

Features like parallel execution, fast finality, and the safety of Move help ensure institutions can focus on the asset and workflow rather than the underlying infrastructure.

As tokenized assets, stablecoins, and automated financial systems scale, this is where markets and machines begin to converge. In that environment, consistent execution matters far more than peak throughput. That’s where technical architecture becomes a business outcome.

As more financial assets move on-chain, how should the industry think about the relationship between public blockchain transparency and the privacy or compliance requirements of traditional financial institutions?

Transparency and privacy are not opposing goals.

Institutions need auditability, regulatory oversight, and verifiable settlement, while also requiring confidentiality around sensitive financial activity.

The long-term solution is not choosing one over the other. It is building systems where outcomes can be verified without unnecessarily exposing underlying information.

That becomes increasingly important as markets become more automated and trust shifts from manual processes to cryptographic verification.

Looking ahead, what role do you want Aptos Labs to play in the next phase of institutional blockchain adoption: infrastructure provider, ecosystem builder, capital markets partner, or something broader?

Markets are already moving on-chain through tokenized assets, stablecoins, and settlement infrastructure. At the same time, machine-driven systems are emerging that can transact, allocate capital, and interact directly with those markets.

Aptos is being built to support both. That means providing the infrastructure for financial markets to operate at scale while enabling increasingly autonomous systems to participate in the economy.

Performance, reliability, and continuous operation are not optional characteristics in either environment. They are foundational requirements.

We believe the convergence of markets and machines will drive the next phase of infrastructure demand.
