Wall Street's Private Blockchain Revival Could Backfire, Ethereum Advocate Warns
A new wave of private, permissioned blockchain networks is sweeping across Wall Street, and at least one prominent voice in the crypto industry is sounding an alarm. Vivek Raman, co-founder and CEO of Etherealize, argues that the resurgence of so-called consortium chains risks recreating the very silos and inefficiencies that blockchain technology was designed to eliminate. The debate comes as major financial institutions weigh whether to build on open, public networks like Ethereum or retreat into gated systems controlled by corporate sponsors.
Raman, whose firm is dedicated to bringing traditional finance onto Ethereum, described the current enthusiasm for consortium chains as a potential replay of a failed experiment from nearly a decade ago. In 2016, banks including Goldman Sachs, Morgan Stanley and Santander joined R3, a blockchain consortium that promised to streamline financial processes. The initiative unraveled before the year was out, with the major lenders withdrawing from the system.
"It's like we're having consortium chain 2.0," Raman said. "This is going to end up being a race to the bottom for consortium chains. You're going to have consortium chains versus consortium chains."
A consortium chain is a blockchain that restricts participation to approved members rather than being open to anyone, as Ethereum or Bitcoin are. Proponents pitch these gated networks on privacy and reduced counterparty risk, qualities that appeal to regulated financial firms wary of exposing trading activity on a public ledger. Current examples gaining traction include Digital Asset's Canton Network, Circle's stablecoin payments system ARC, and Stripe's Tempo blockchain.
Raman's critique centers on interoperability. He argues that a fragmented landscape of competing consortium chains would undermine the liquidity and connectivity that open networks provide. He compared Ethereum's public mainnet to HTTP, the base protocol of the internet, with permissioned layers like HTTPS built on top.
"We strongly believe, and always have done, that you need a global, open, permissionless infrastructure as the base layer," Raman said. "Then you can build all the permissioning on top of it. Whether that's at the app layer, whether that's the L2 layer, that's where you should have the customizability."
Raman pointed to BlackRock's recent moves as evidence that regulatory clarity pushes institutional money toward open networks. The asset manager began with its BUIDL token on Ethereum and has since developed new funds compliant with the GENIUS Act, the U.S. regulatory framework for stablecoins. "When we have regulatory clarity the institutional money goes toward open networks because that's the rails that no one owns," Raman said.
Not everyone shares Raman's assessment. Christian Catalini, founder of the MIT Cryptoeconomics Lab and former chief economist of Facebook's Diem stablecoin project, offered a counterpoint. He noted that the rapid adoption of gated, sponsor-controlled systems suggests the market may not prioritize decentralization at all.
"This phase is all about enterprise sales," Catalini said. "So there's this really interesting tension just now, right as the real money is about to come in, and it's not clear which way we will land. If we land on these networks that are more curated and have a clear sponsor and anchor entity shaping their rules, then some of the pro-competitive benefits of blockchains will never materialize."
Raman's warning should be understood in context. Etherealize was seeded by a grant from Ethereum co-founder Vitalik Buterin and the Ethereum Foundation in January 2025, and it raised $40 million in Series A funding later that year. The company's stated purpose is attracting traditional finance firms to Ethereum's open network, meaning Raman's prediction that consortium chains will fail is also a case for why banks should build on Ethereum instead.
The debate over public versus private blockchain infrastructure is unfolding against a backdrop of significant volatility in digital asset markets. Bitcoin has declined 47% over the past twelve months, according to Strategy (MSTR) Chairman Michael Saylor, while the S&P 500 index rose 22% over the same period. That performance gap has intensified scrutiny of crypto-linked investment products and the broader institutional adoption narrative.
Strategy itself has become a case study in financial engineering around digital assets. The company's STRC preferred stock, part of its digital credit suite, posted a 9% return over the past year while Bitcoin fell sharply. The instrument carries a 12% variable annual dividend paid semi-monthly, with the rate adjusted monthly to encourage trading near its $100 stated amount. Strategy's digital credit products overall returned between negative 27% and positive 9% during the period.
The stability offered by such structured products has come at a cost. Strategy's total annual payment obligations to holders of its structured products have surpassed $1.2 billion. To fund these payouts, the company has been selling portions of its Bitcoin reserve since August 2026, including $104 million worth of coins in recent transactions.
The parallel narratives underscore a broader question facing the crypto industry: whether the future lies in open, permissionless networks that prioritize decentralization, or in curated systems that offer the control and privacy traditional finance demands. Raman's argument is that the former is the only sustainable path. Catalini's observation suggests the market may not care about the philosophical distinction.
What is clear is that the stakes have grown considerably since R3's collapse in 2016. The tokenization of real-world assets, the emergence of stablecoin regulation, and the entry of major asset managers like BlackRock have transformed what was once a niche technical debate into a strategic decision with billions of dollars at stake. Whether today's consortium chains avoid the fate of their predecessors remains an open question, but the outcome will shape the architecture of institutional crypto for years to come.
