A consortium chain is a blockchain that only lets in companies invited to join it, rather than being open to anyone the way Ethereum or Bitcoin are. Vivek Raman, chief executive of the Ethereum-adoption firm Etherealize, argues in an interview reported by CoinDesk on 15 August 2026 that Wall Street’s current enthusiasm for these gated networks recreates the same silos blockchain technology was supposed to eliminate. That is a forecast from someone whose company is paid to bring institutions onto the open alternative, not an independent finding. This page separates the two: what a consortium chain actually is, and what happened the last time banks built one, versus Raman’s prediction about what will happen this time – and it states outright, rather than in passing, that the person making the prediction runs a business whose success depends on it coming true.
Open, public networks like Ethereum allow anyone to participate, and every transaction is visible to any participant on the network – CoinDesk’s report describes Ethereum as a network where ‘all transactions are visible to everyone.’ A consortium chain restricts that participation and visibility to approved members only. CoinDesk reports that examples now gaining traction on Wall Street include Digital Asset’s Canton Network, Circle’s stablecoin payments system ARC, and Stripe’s Tempo. These systems, CoinDesk reports, are pitched on privacy and reduced counterparty risk – qualities that appeal to regulated financial firms wary of exposing trading activity on a public ledger.
CoinDesk’s reporting places today’s push in the context of R3, a bank consortium that drew in major lenders starting in 2016. Per CoinDesk, R3 did not make it to the end of that year before large banks – Goldman Sachs, Morgan Stanley and Santander – withdrew. Raman, in the CoinDesk interview, described the current wave as “consortium chain 2.0” and said it would become “a race to the bottom for consortium chains.” Separately, Crypto Briefing reported, per its own summary, that Raman argues banks building walled-garden blockchains are recreating the inefficiencies they are trying to escape – a similar critique to the one CoinDesk recorded.
Raman told CoinDesk he favors building privacy and permissioning on top of an open foundation rather than replacing it. He compared Ethereum’s public mainnet to HTTP, the internet’s base protocol, with a more secure, permissioned layer – HTTPS – built on top. He told CoinDesk institutions need “a global, open, permissionless infrastructure as the base layer,” with customization handled at the application or Layer 2 level. He pointed to BlackRock’s move from its BUIDL token on Ethereum toward new funds built to comply with the GENIUS Act, the U.S. stablecoin framework, as evidence that regulatory clarity pushes institutional money toward open networks rather than consortiums, according to CoinDesk.
Etherealize’s initial funding came from a January 2025 grant by Ethereum co-founder Vitalik Buterin and the Ethereum Foundation; the company then raised $40 million in a Series A round later that year, according to CoinDesk and a Crypto Briefing summary of its own reporting. Its stated purpose, per CoinDesk, is attracting traditional finance firms to Ethereum’s open network. That means Raman’s prediction that consortium chains will fail is also a case for why banks should build on Ethereum instead – the product his company sells. CoinDesk’s report includes a counterpoint from Christian Catalini, founder of the MIT Cryptoeconomics Lab and former chief economist of Facebook’s Diem stablecoin project, who told CoinDesk that the rapid adoption of gated, sponsor-controlled systems suggests the market may not care about decentralization at all. “This phase is all about enterprise sales,” Catalini said, adding that if institutions settle on networks with a clear sponsor and anchor entity, “some of the pro-competitive benefits of blockchains will never materialize.”
This account rests on a single newsroom’s interview – CoinDesk’s, published 15 August 2026. No other independent reporting in the evidence gathered corroborates Raman’s or Catalini’s quotes directly; other outlets either republish CoinDesk’s account or could not be verified as full articles. No transaction-volume, asset or bank-membership data on Canton Network, ARC or Tempo appears anywhere in this evidence, so there is no way to check the “race to the bottom” prediction against how these networks are actually being used, and this page does not attempt to settle whether today’s rush will end the way R3’s did. No representative of Digital Asset, Circle or Stripe is quoted responding to Raman’s characterization in any source reviewed here. And Raman’s forecast that consortium chains will fail should be read as the argument of someone whose company’s commercial success depends on that outcome, not as a disinterested technical assessment.
Every fact above is attributed to one of these reports. Where they disagree, the article says so.
