I spent years auditing smart contracts, and the most dangerous vulnerabilities are never in the code. They are in the assumptions about who gets to verify, who gets to decide, and who gets to walk away. Last week, I reviewed a private blockchain implementation for a major bank—a pilot meant to settle repurchase agreements among a consortium of six institutions. The Solidity was clean, the cryptography was standard, and the attack surface was minimal. But the governance model was a disaster. The validator set was controlled by a board of directors who met quarterly, and the off-chain dispute resolution mechanism relied on a single legal firm. I told the project lead that this was not a blockchain. It was a distributed database with a fancy audit trail. He smiled and said, 'That's what the regulators want.'
That conversation came back to me when I read Etherealize CEO Vivek Raman's recent warning that Wall Street's private blockchain push is a 'race to the bottom.' Raman is not wrong, but he is only half-right. The problem is not that private chains are technically inferior—they can be faster, cheaper, and more compliant in the short term. The real problem is that they replicate the very trust dependencies that blockchain was supposed to eliminate. And in doing so, they create a governance trap that will be far more expensive to escape than any technical debt.
The Context: Public vs. Private as a Governance Choice
Let me step back. Etherealize is a marketing and education arm for the Ethereum ecosystem, specifically tasked with winning institutional mindshare. Raman himself is a former Wall Street bond trader who now argues that public blockchains like Ethereum offer a 'scalable, transparent solution' for finance, while private chains 'perpetuate inefficiencies' because each institution builds its own siloed ledger. On the surface, this is a familiar debate: public chains maximize decentralization and openness, private chains maximize control and compliance. But the deeper story is about governance architecture—how decisions are made, how conflicts are resolved, and how trust is distributed.
I have been in this debate since 2017, when I audited 15 ICO projects and refused to sign off on 'EtherTrust' because their code had a reentrancy vulnerability that would have allowed a single malicious actor to drain the entire treasury. The founders called me a 'blocker.' I published a whitepaper titled 'Code as Conscience,' arguing that decentralization requires moral accountability, not just mathematical trust. That experience taught me that the blockchain industry is not a technology industry. It is a governance industry disguised as a technology industry. And the public vs. private chain debate is fundamentally a governance debate.
Wall Street is attracted to private chains because they offer a familiar power structure: permissioned validators, KYC/AML built-in, and the ability to roll back transactions if something goes wrong. But the very features that make private chains appealing to risk managers also make them structurally fragile. When the validator set is controlled by a consortium of banks, the network is only as trustworthy as the weakest governance process among them. And consortium governance is notoriously brittle. I saw this firsthand in 2020, when I joined the Community DAO as a governance architect. We designed a quadratic voting system to prevent whale dominance, but a signature replay attack drained $50,000 from the treasury. The technical fix was simple—update the signature verification logic. The governance fix was impossible. The attacker had been a trusted member of the community, and the DAO had no mechanism to expel a malicious actor without a unanimous vote that never came. I retreated to the Victorian bushlands for three months, exhausted by the betrayal of communal ideals. That experience taught me that governance failures are not bugs; they are features of systems that trust too much in a small group of people.
Private chains are the same. They trust a small group of institutions to act in good faith, but they provide no mechanism for external verification, no exit for dissenting members, and no transparency for the broader market. The result is not just inefficiency—it is a system that is inherently fragile to collusion, regulatory capture, and internal politics.
The Core Insight: Trust Models and the Race to the Bottom
Raman's phrase 'race to the bottom' is precise. In economics, a race to the bottom occurs when competing entities lower standards to gain a short-term advantage, ultimately degrading the entire system. In the context of Wall Street private chains, the race is not about technology—it is about governance standards. Each bank builds its own chain with its own validator set, its own smart contract standards, and its own compliance rules. The result is a fragmented ecosystem where no two chains can interoperate without a third-party bridge, which reintroduces the very trust issues the chains were supposed to solve.
I have seen this fragmentation firsthand. In 2022, after the FTX collapse, I was asked to evaluate a private-chain-based settlement network for a group of asset managers. The technical documentation was impressive—they had a custom consensus algorithm that could handle 10,000 transactions per second, with finality in under a second. But when I asked about the governance documentation, I was handed a PDF with a list of 12 member institutions and a voting threshold of 75% for any protocol change. 'What happens if one member wants to leave?' I asked. 'They can't,' the architect replied. 'The network is their only settlement option.' That is not a race to the bottom. That is a cage.
Public chains, by contrast, offer a fundamentally different trust model. The validator set is permissionless, the ledger is transparent, and the governance is open—though messy. The Ethereum community has debated EIP-1559, the merge, and the blob fee market through a process that is far from perfect but is at least visible to anyone who cares to participate. This transparency is not just a technical feature; it is a governance feature. It allows external auditors, regulators, and competitors to verify the network's integrity without relying on the goodwill of a small group of institutions.
But here is the nuance that Raman's article avoids: transparency is not the same as privacy. Wall Street institutions need to keep their trading strategies confidential, and they have legitimate concerns about front-running, MEV, and regulatory oversight. Public chains have made progress on privacy through zero-knowledge proofs and zk-rollups, but these solutions are still maturing. In 2021, I partnered with indigenous Australian artists to mint 100 NFTs on Ethereum, ensuring 10% of royalties went to community trusts. The project raised $150,000, but I faced intense pressure to flip the assets for quick profit. I resisted, and the experience taught me that privacy is not just about hiding data—it is about preserving the cultural integrity of a community. The same principle applies to Wall Street. Institutions need selective disclosure: they need to prove that a transaction is valid without revealing the details to the entire world. Public chains are not there yet, and that is a real gap.
The Contrarian Angle: The Blind Spots in the Public Chain Narrative
Raman's argument is compelling, but it has blind spots that are strategically significant. The most important is the assumption that public chains can scale to meet institutional demand while maintaining decentralization. Post-Dencun, the Ethereum blob space is already under pressure. I expect that within two years, the blob data will be saturated, and all rollup gas fees will double again. This is not a catastrophic failure—it is a natural consequence of exponential demand. But it means that institutions cannot simply 'move to Ethereum' and expect the same throughput they enjoy on a private chain. They will need to compete for blob space, and that competition will drive up costs. The race to the bottom might actually be a race to the top of the fee market, where only the largest institutions can afford to settle.
Another blind spot is the assumption that private chains are inherently 'inefficient.' In reality, some private chains have achieved remarkable efficiency in specific use cases. JPMorgan's Onyx network has processed over $1 trillion in repo transactions since its launch, and Canton Network has demonstrated interoperability across multiple private chains. These are not toy projects; they are production systems that handle real economic value. The inefficiency Raman criticizes is not technical—it is governance-based. The institutions are not failing because their blockchains are slow; they are failing because they cannot agree on a common standard. But that is a political problem, not a technological one. And public chains are not immune to political problems. The Ethereum community's inability to finalize a privacy standard after years of research is a testament to the difficulty of governance at scale.
I also want to address the elephant in the room: the 90% of so-called 'Bitcoin Layer 2s' that are actually Ethereum projects rebranding for hype. The real Bitcoin community does not acknowledge them, and they represent a distraction from the genuine innovation happening in the Bitcoin ecosystem. But the same dynamic applies to the public vs. private chain debate. Many of the projects claiming to be 'institutional-grade public chains' are anything but. They rely on centralized sequencers, closed-source code, and governance tokens that are controlled by a small group of early investors. The line between public and private is blurry, and Raman's binary framing obscures the real complexity.
The Takeaway: Governance, Not Technology, Will Decide the Winner
I have been in this industry long enough to know that the chain with the best technology does not always win. The chain with the best governance does. In 2024, I advised a major Australian pension fund on integrating crypto into their portfolio. I negotiated a clause ensuring that 5% of the allocated funds would be directed toward open-source infrastructure projects. This move was heavily criticized by traditionalists who saw it as unorthodox, but it demonstrated that institutional capital can drive positive change if guided by ethical principles. The pension fund did not care about whether the chain was public or private. They cared about whether the governance model was transparent, accountable, and resilient to capture.
So where does that leave us? The race to the bottom is real, but it is not a feature of private chains—it is a feature of any governance system that lacks transparency, accountability, and exit options. Public chains have the theoretical advantage, but they need to solve the privacy and scalability challenges before they can credibly claim to be the better option for Wall Street. The next 12 months will be critical. If we see a single major institution publicly migrate from a private chain to a public one, the narrative will shift. If not, Raman's warning will be remembered as a well-intentioned but premature call to arms.
For now, the architecture of trust is not just a technical choice; it is a moral one. The blockchain industry has spent too much time arguing about which chain is faster, cheaper, or more decentralized. The real question is: which chain is more likely to survive the next crisis? The answer is not in the code. It is in the governance.
