Many crypto enthusiasts dream of trading traditionalequities around the clock on public blockchains. They imagine a decentralizedutopia where anyone can buy fractional shares of major corporations withouttraditional brokers. This vision fundamentally misunderstands how institutionalfinance operates. In my opinion, major tokenized stocks will never migrate topublic networks. The future of twenty-four-hour equity trading belongsexclusively to private or semi-private blockchain architectures.Regulatory Signals Fuel the NarrativeThe UnitedStates Securities and Exchange Commission recently proposed rescinding twokey rules under Regulation National Market System.Related: A Token Is Only as Good as the Share Behind It - How Four Crypto Exchanges' SpaceX Bets Came Up EmptyThese rules require trades to be routed to the national bestprice and prohibit locked or crossed quotes across venues. Analysts like AlexThorn note that automated market makers on public chains conflict with theserequirements because they execute against isolated liquidity pools withoutchecking off-chain quotes. Removing the rules could theoretically open the doorto compliant on-chain trading of tokenized United States equities.However, this remains a medium-term structural adjustmentrather than an immediate green light. The proposal still faces a lengthycomment process, and platforms would still need to register as exchanges oralternative trading systems, satisfy clearing obligations, and ensure tokenholders retain voting and dividend rights. Traditional market groups also warn that removing the rulescould reduce price transparency and fragment markets.Operational Constraints of Public BlockchainsEven with favorable regulations, public blockchains presentsignificant operational hurdles for institutionalequity trading. Gas fee volatility remains a primary deterrent. A surge inretail activity can congest public networks and sharply increase transactioncosts. Institutions cannot risk large equity settlements beingdelayed or becoming more expensive because of unrelated retail traffic.Traditional financerequires deterministic execution.A bank executing a large block trade needs certainty aroundcost and settlement timing. Institutional traders require millisecond precisionand reliable finality. Public networks prioritize openness and censorshipresistance over the predictable throughput global capital markets demand.Maximal Extractable Value (MEV) presents another criticalbarrier. Public blockchains broadcast pending transactions in a public mempoolbefore execution. Sophisticated actors deploy bots to scan this information andfront-run large orders by manipulating transaction ordering. Billions of dollars have been extracted through thesepractices in recent years. This directly conflicts with the fiduciaryobligations of traditional brokers and institutional mandates requiring bestexecution. Financialinstitutions are unlikely to embrace a system that permits such extractionfrom client order flow.Privacy, Compliance, and Control RequirementsPrivacy and compliance requirements further strengthen thecase against public ledgers. Traditional finance operates under strict KnowYour Customer and Anti-Money Laundering regulations. Public blockchains exposetransaction data to everyone. Institutions cannot broadcast their strategicpositioning or client holdings on a transparent ledger. Regulators also requirethe ability to freeze assets or reverse transactions under specific legalcircumstances. Public blockchains generally resist these interventions,creating challenges when compliance frameworks require administrative control.Wall Street is warming to tokenized stocks. The dream of eliminating middlemen? That’s another story https://t.co/jHO9RtW9fy— Businessweek (@BW) June 17, 2026Private networks provide the logical solution. A privateblockchain functions as a shared, cryptographically secure ledger maintained bya trusted group of regulated institutions. This architecture delivers many of the benefits ofdistributed ledger technology without the unpredictability of public networks.Competitors cannot observe order flows, trade sizes, or account balances.Transactions remain confidential between authorized participants and regulators.These networks can also streamline clearing and settlementby enabling institutions to transact directly with one another. This lowerscosts, reduces counterparty risk, and supports continuous settlement.Enterprise networks further offer dedicated support and contractual serviceguarantees that public protocols do not provide.Institutional Adoption Is Already UnderwayMajor financial institutions already recognize this reality.J.P. Morgan operates its Onyx platform for tokenized intraday repurchaseagreement trades and payments. Goldman Sachs uses its Digital Asset Platform toissue and trade digital bonds and other institutional instruments. HSBC's Orion platform supports tokenized gold and digitalbond issuance. These examples demonstrate that financial institutions viewblockchain primarily as infrastructure for automation, synchronization, andefficiency within controlled environments.The Direction of Tokenized EquitiesMarket participants continue to pursue the vision of tradingmajor corporate shares on public decentralized exchanges. Yet the structural,regulatory, and operational realities of global finance point elsewhere. The Securities and Exchange Commission may eventually adaptmarket rules for digitalassets, but the infrastructure itself will remain largely in private hands.Tokenized equities are far more likely to thrive on secure,permissioned networks designed for institutional performance and compliancethan on fully public chains. The future of financial innovation is not publicexposure. It is private, efficient infrastructure built to meet the demands ofmodern capital markets.This article was written by Anndy Lian at www.financemagnates.com.
