Why has blockchain, the underlying technology behind Bitcoin, gone from being dismissed by Wall Street to becoming a new favorite among financial giants？
Imagine this: One day, as a non-U.S. citizen, you buy a share of Apple stock. You dont have to wait for traditional financial markets to open or go through a complicated series of settlement procedures. Instead, you can transfer your shares through a blockchain and, where permitted by applicable rules, even use them as collateral for on-chain lending.
Meanwhile, the U.S. dollar circulates on blockchain networks in the form of stablecoins. Treasury securities, funds, and an expanding range of traditional financial assets are also beginning to have their own on-chain versions.
Does it sound like something out of a science-fiction movie？ Yet this is no longer just a fantasy dreamed up by the crypto industry.
In 2026, the U.S. Securities and Exchange Commission (SEC) introduced a temporary, conditional innovation exemption for certain tokenized U.S. stock trading scenarios, creating new opportunities for eligible on-chain securities trading venues to experiment.
But lets be clear: This does not mean that all U.S. stocks can now be freely moved onto blockchains and traded without restrictions, nor does it mean regulators have fully opened the floodgates.
Instead, it sends an important signal: Blockchain is gradually evolving from a challenger operating outside the traditional financial system into infrastructure that established financial institutions are willing to explore and adopt.
So here is the big question: Why are Bitcoin and crypto technologies, once viewed as threats by Wall Street, now attracting increasing attention from traditional financial institutions？
And why is this happening now？
To understand the answer, we need to turn the clock back to 2008.
1. Bitcoin Was Born: Who Was It Challenging？
The most immediate catalyst for Bitcoins creation was the global financial crisis of 2008.
At the time, major financial institutions were struggling, and public confidence in the banking system and traditional financial intermediaries had been severely shaken.
Against this backdrop, an individual or group using the name Satoshi Nakamoto published the Bitcoin white paper. In January 2009, the Bitcoin network officially went live.
Bitcoin introduced a radical idea: What if people could transfer value without relying on a single bank or a centralized institution to decide who was allowed to make a transaction？ What if cryptography, a distributed network, and a consensus mechanism could enable participants to collectively maintain a public transaction ledger？
How does traditional finance work？
When you deposit money in a bank, the bank records your balance. When you buy stocks, brokers, exchanges, custodians, and clearing and settlement systems work together to maintain records of transactions and ownership.
Bitcoin sought to demonstrate that the transfer of certain digital assets and the maintenance of their transaction records could be handled through the rules of an open network.
That was one of Bitcoins most important innovations.
But this new model also raised difficult questions.
If money can move across borders, users can custody their own assets, and transactions no longer depend entirely on traditional intermediaries, how can regulators prevent money laundering, fraud, market manipulation, and investor losses？
These concerns became particularly acute in the early crypto market, where exchange collapses, project failures, price manipulation, and stolen funds were frequent occurrences.
For regulators, this new world represented not only technological innovation but also a new set of risks.
As a result, the relationship between crypto and traditional finance remained a prolonged tug-of-war, with both sides testing the boundaries of what was possible.
Yet Bitcoin left behind a question that could not be ignored: If blockchain can facilitate the transfer of digital assets without direct involvement from traditional intermediaries, could it also improve how traditional finance operates？
That question would help drive the industrys development over the next decade and beyond.
2. Crypto Builds Its Own Financial System: DeFi, Independent of Traditional Finance
If Bitcoin demonstrated that digital assets could operate on an open network, the crypto industry soon began trying to build an entire financial system on top of that network.
The first crucial piece of the puzzle was stablecoins.
Why are stablecoins so important？
Bitcoins price is far too volatile to serve as a stable unit of account in most trading scenarios. In the early days of crypto, daily price swings of 10% to 20% were not unheard of, while prices could differ by as much as 80% between market peaks and troughs.
Imagine spending $10,000 to buy Bitcoin today. Tomorrow, your holdings might be worth $20,000—or they might have fallen to just $5,000.
Such volatility is clearly unsuitable for many on-chain lending, trading, and asset management activities.
That is why stablecoins designed to track the U.S. dollar gradually gained traction. Products such as USDT and USDC made it possible to move dollar-denominated value across different blockchains and crypto applications.
This was a major milestone. In effect, stablecoins brought the dollar into a new digital financial network.
Of course, stablecoins are not the same as bank deposits. Different stablecoins may have different reserve arrangements, redemption mechanisms, and legal protections. Nevertheless, from a functional perspective, they addressed one of the most fundamental needs of on-chain finance: how to move and settle funds.
The second piece of the puzzle was DeFi, or decentralized finance.
In traditional finance, you generally need a bank to borrow money and a trading platform to exchange assets. DeFi, by contrast, attempts to use smart contracts to automate trading, lending, collateral management, and liquidation according to predefined rules.
Users can deposit assets into protocols or use eligible assets as collateral to borrow funds.
But smart contracts do not eliminate risk. Coding vulnerabilities, sharp declines in collateral values, and failures in liquidation mechanisms can all lead to losses.
The third piece of the puzzle was infrastructure.
Public blockchains provide the networks on which smart contracts operate. Wallets allow users to manage their assets. Oracles bring external information, such as market prices, onto the blockchain. Cross-chain tools attempt to connect different blockchain networks.
By this point, the crypto industry had evolved beyond Bitcoin and a collection of tokens. It was gradually developing an entire financial ecosystem encompassing assets, digital dollars, trading, lending, and data services.
However, this ecosystem had one obvious limitation: Most of its activity still revolved around crypto-native assets.
So, could assets originating in traditional financial markets also be brought into this system？
That question leads us to the third stage of the story.
3. Wall Street Discovers That Blockchain Is More Than Just a Tool for Issuing and Speculating on Tokens
When people hear about RWA, or the tokenization of real-world assets, their first thought is often simple: turning real-world assets into tokens.
But that is only the surface. The real question worth exploring is this: Once assets are brought onto a blockchain, can they be issued, transferred, settled, used as collateral, and managed more efficiently？
Lets start with U.S. Treasury securities. Treasuries are among the most important assets in the global financial system, backed by relatively mature legal frameworks, valuation systems, and trading markets.
Suppose a regulated fund holds U.S. Treasury securities and, through an appropriate legal and issuance structure, represents its fund shares as tokens that can be transferred on a blockchain. Those tokenized shares could then have opportunities to enter digital financial applications.
One important distinction: Owning tokenized fund shares does not necessarily mean investors directly own each underlying Treasury security. Their actual rights depend on the fund structure and its legal documentation.
So why are Treasuries and money market funds worth watching？
Because they are more than just investment assets. They can also support cash management, collateral arrangements, and liquidity allocation. These functions have natural connections to stablecoins and on-chain lending.
Once a blockchain ecosystem has dollar-denominated assets, trading venues, and lending protocols, adding eligible yield-bearing assets could help create a more complete financial ecosystem.
Next, consider credit assets. Loans and other debt claims can also be digitally managed and issued through appropriate structures. However, they involve borrower creditworthiness, asset valuation, default resolution, and investor rights. Simply writing a loan into a smart contract does not make all these challenges disappear.
So why not start directly with stocks？
The immediate reason is that equity markets operate under much more complex rules.
A stock is more than a price quoted on a screen. It involves shareholder rights, voting, dividends, stock splits, trading halts, disclosure requirements, and the legal relationship between a listed company and its shareholders.
If you buy a token claiming to represent Apple stock, you need to understand exactly what you own: Do you hold genuine equity rights in Apple, or merely a contract that tracks Apple's share price？
The risks are fundamentally different.
Genuine tokenized securities must address the connections between underlying assets, legal rights, custody, ownership registration, redemption, and trading rules.
That is precisely why traditional financial institutions are increasingly looking beyond simply issuing tokens. They are beginning to explore how blockchain can be integrated into existing financial infrastructure.
4. Regulators Begin Exploring a New Framework: Testing the Waters in a Regulatory Sandbox
Now we come to the SEC. Why are regulators beginning to change how they approach this technology？
First, we need to distinguish between several different developments.
In 2025, SEC Chair Paul Atkins advanced Project Crypto, proposing updates to the regulatory framework for digital assets so that U.S. financial markets could better accommodate blockchain technology.
That same year, SEC Commissioner Hester Peirce issued a statement specifically addressing tokenized securities. She emphasized a central principle: Whether a security exists in traditional form or as a token, its status as a security and the corresponding legal requirements do not automatically disappear simply because its technological format changes.
In January 2026, SEC staff from the Divisions of Corporation Finance, Investment Management, and Trading and Markets issued a staff statement on tokenized securities.
The statement distinguished between two important structures.
The first is issuer-sponsored tokenization. For example, an issuer may incorporate blockchain into its securities-holder registration system so that on-chain transfers correspond to changes in securities ownership.
The second involves third-party tokenization. A third party may hold the underlying securities and issue related tokens through a particular legal and product structure.
These two models can differ significantly in terms of ownership rights, registration, and trading arrangements.
Regulatory discussions were becoming increasingly focused on a practical question: If securities remain subject to securities laws, how should blockchain technology operate within the existing legal framework？
Then, in September 2026, the SEC introduced a temporary, conditional innovation exemption for certain tokenized U.S. stock trading scenarios, providing limited regulatory relief for eligible trading venues and certain liquidity providers.
This was not an end to regulation. Instead, it was an attempt to test new trading mechanisms within defined boundaries.
What does the SEC want to observe？
Can these trading mechanisms operate reliably？ Can prices remain reasonable？ Can investor rights be protected？ Can market manipulation and fraud be controlled？ And can on-chain trading be integrated with existing securities market rules？
These questions cannot be answered by a white paper alone. They require real-world market data and practical experience.
Therefore, the most important aspect of this development is not a simplistic headline claiming that the SEC has given the green light to putting U.S. stocks on the blockchain.
It is that regulators are beginning to explore how new technological mechanisms can enter traditional securities markets under clearly defined conditions.
5. The Real Turning Point: Blockchain Is Competing for Control of Financial Infrastructure
At this point, we can connect the dots.
Stage One: Bitcoin demonstrated that an open network could maintain a ledger of digital assets.
Stage Two: Stablecoins, DeFi, public blockchains, wallets, and oracles gradually built the foundations of a digital financial infrastructure.
Stage Three: Traditional financial institutions began experimenting with bringing assets such as Treasuries, funds, and credit products onto blockchains.
Stage Four: Regulators started exploring institutional frameworks capable of accommodating these new technologies.
Against this backdrop, the tokenization of U.S. stocks is no longer an isolated crypto market trend. It represents a convergence of financial technology developments spanning more than a decade.
At least three major forces are driving this transformation.
The first is efficiency.
Traditional finance involves multiple institutions and systems. In certain applications, blockchain could improve asset recordkeeping, transfers, settlement, and collateral management.
The second is market competition.
If new trading infrastructure can deliver a better user experience, traditional exchanges, brokerages, and crypto platforms will have to consider how to respond.
The third is the digitization of financial markets.
As dollars, Treasuries, funds, and stocks become accessible to blockchain networks in different forms, financial institutions may have opportunities to redesign asset management, payment, and trading processes.
However, we should not overlook the other side of the story.
On-chain trading does not guarantee greater liquidity. Around-the-clock trading does not mean prices will always be fair. And tokenizing an asset does not automatically eliminate custody, redemption, or legal risks.
There is even a possibility that traditional financial institutions will use blockchain to improve efficiency while continuing to maintain tight control over the assets, customers, and compliance gateways.
If that happens, blockchain adoption could grow significantly, while some tokens held by ordinary crypto investors might not benefit at all.
That is why analyzing tokenized U.S. stocks requires more than simply watching which tokens carry an RWA label.
The more important questions are: Who supplies the assets？ Who provides the dollar liquidity？ Who controls access to trading？ Who actually earns the revenue？ And can that revenue ultimately flow through to the investment assets associated with the trend？
Conclusion: Now That Wall Street Is Embracing Blockchain, Do the Old Rules of Crypto Still Apply？
Lets return to our original question: Why now？
Over the past decade and a half, the crypto industry has gradually demonstrated that blockchain can do more than create new digital assets. It can also support trading, lending, the movement of funds, and automated financial services.
Traditional finance is now attempting to bring these capabilities into regulated securities and asset markets.
Technology has reached a certain level of maturity. Institutions are looking for commercial applications. Regulators are exploring new institutional boundaries.
It is the convergence of these three developments that has fueled today's tokenized U.S. stock movement.
But where this transformation will ultimately lead remains an open question.
It could become an upgrade to traditional financial infrastructure, or it could create a new landscape in which traditional and crypto markets coexist over the long term.
For investors, the most important task is not predicting which token will surge first. It is understanding how the financial value chain is changing.
Here is one final question to consider:
If Wall Street eventually moves beyond simply buying Bitcoin and investing in crypto companies, and starts using blockchain directly to issue, trade, and manage traditional financial assets, will the competitive rules that have defined the crypto industry still hold true？
