Raman argues that banks building closed, permissioned ledgers are trading away the openness that makes blockchain technology valuable in the first place.
Ethereum advocate Raman has raised concerns about a wave of private blockchain projects launched by large financial institutions. Speaking to CoinDesk, Raman described the trend as a 'race to the bottom,' suggesting banks are chasing blockchain branding without embracing its core principles.
Wall Street firms have increasingly explored blockchain technology over the past several years. Many have opted to build permissioned, closed-loop networks rather than deploy applications on public chains like Ethereum. These private systems typically restrict participation to approved institutions and limit visibility into transaction data.
Raman's critique centers on a tension that has long defined institutional crypto adoption. Public blockchains such as Ethereum offer transparency, decentralization, and composability. These features allow independent developers to build interoperable applications on shared infrastructure. Private blockchains, by contrast, often replicate traditional banking architecture. They add cryptographic record-keeping without changing who controls the network.
According to CoinDesk's reporting, Raman argues that this approach risks diluting the value proposition of blockchain technology altogether. Institutions can claim they are innovating with distributed ledgers, Raman suggested, while avoiding the accountability and openness that public networks require. The result, in Raman's view, is a competitive dynamic where firms differentiate less on technical merit and more on marketing.
This debate is not new to the crypto industry. Since the early days of enterprise blockchain pilots, developers on public networks have questioned whether permissioned systems deliver meaningful benefits over conventional databases. Proponents of private chains counter that regulatory requirements, data privacy rules, and compliance obligations make fully public infrastructure impractical for many financial use cases.
Raman's comments arrive as institutional interest in blockchain-based settlement, tokenization, and custody continues to grow. Major banks and asset managers have piloted or launched blockchain projects tied to tokenized funds, trade settlement, and interbank transfers. Many of these initiatives rely on private or consortium-based networks rather than public chains like Ethereum or Solana.
The Ethereum ecosystem has positioned itself as an alternative foundation for institutional finance, emphasizing its established security model and broad developer base. Advocates like Raman argue that building on public infrastructure would allow institutions to benefit from network effects already present in decentralized finance. Critics of that view maintain that public blockchains still face scalability, privacy, and regulatory hurdles that make them unsuitable for certain institutional workflows.
CoinDesk's report frames Raman's remarks as part of a broader conversation about the direction of institutional blockchain adoption. The comments do not target any single bank or project by name, based on available reporting. Instead, they describe a general pattern Raman sees developing across Wall Street's approach to distributed ledger technology.
Market Impact
Raman's comments are unlikely to move markets directly, since they represent commentary rather than a specific business or regulatory development. However, the remarks touch on a strategic question relevant to Ethereum's long-term positioning as institutional infrastructure. If large financial institutions continue favoring private, permissioned networks, that could limit direct capital flows and transaction volume onto public chains like Ethereum, even as blockchain adoption broadly increases.
The debate also carries implications for how tokenization and settlement projects are structured going forward. Institutions weighing private versus public infrastructure choices will shape which networks capture developer activity, liquidity, and eventual retail access to tokenized financial products.
Raman's warning highlights an unresolved tension in institutional blockchain adoption between control and openness. As more banks explore distributed ledger technology, the choice between private and public infrastructure remains a central question for the industry's future direction.
Frequently Asked Questions
What did Raman say about Wall Street's blockchain strategy?
According to CoinDesk, Raman described the growing use of private blockchains by financial institutions as a 'race to the bottom,' arguing it sacrifices transparency and openness.
What is the difference between a private and a public blockchain?
Public blockchains like Ethereum are open to anyone and allow transparent, decentralized participation. Private or permissioned blockchains restrict access to approved participants and limit visibility into transactions.
Why are banks building private blockchains instead of using public ones?
Institutions often cite regulatory compliance, data privacy requirements, and operational control as reasons for preferring permissioned networks over fully public infrastructure.
Does this criticism target a specific bank or project?
Based on available reporting from CoinDesk, Raman's comments describe a general industry trend rather than naming a specific institution or project.
