Raman, a prominent Ethereum advocate and vocal critic of centralized blockchain initiatives, has issued a sharp warning against what he characterizes as Wall Street's growing obsession with private, permissioned blockchains. In remarks reported by CoinDesk, Raman dismissed the trend as fundamentally misaligned with the core ethos of blockchain technology.
"You're seeing financial institutions essentially recreate the same problems they're claiming to solve," Raman said, according to the report. "Private chains give you the appearance of innovation while delivering all the opacity and single points of failure that traditional finance already suffers from."
Market Context
The comments arrive as major banks and institutional players have accelerated their exploration of distributed ledger technology over the past 18 months. JPMorgan Chase, Goldman Sachs, and BNY Mellon have each announced or expanded blockchain-based settlement and tokenization initiatives, typically using permissioned networks that limit validator participation to approved entities.
Ethereum, by contrast, operates as a public, permissionless network where anyone can participate in transaction validation. The network has been working to scale its infrastructure through upgrades like proto-danksharding and blob transactions designed to reduce costs for high-volume applications.
Analysis
Raman's critique reflects an ongoing philosophical divide within the crypto community about the merits of institutional adoption versus purist decentralization principles. Private blockchains offer institutions greater control, compliance flexibility, and throughput predictability—advantages that mainstream finance has historically prioritized over censorship resistance or trustless architecture.
"Wall Street doesn't want to replace the financial system," Raman argued. "They want to make it slightly more efficient while keeping themselves in the middle of every transaction. That's not a blockchain revolution—that's a database with extra steps."
Defenders of enterprise blockchain initiatives counter that permissioned networks serve legitimate use cases, particularly for interbank settlements and regulatory reporting where data privacy and known validator sets are prerequisites for adoption.
Key Numbers
- JPMorgan's Onyx network has processed over $1.5 trillion in transactions since its 2020 launch, according to the bank
- Goldman Sachs' tokenization platform reportedly handles portions of its $50B+ repo book
- Ethereum processes approximately 1-1.2 million transactions daily at current volumes
What to Watch
The debate is expected to intensify as more traditional financial institutions file patents and announce pilots for blockchain-based products. Ethereum's upcoming Pectra upgrade, targeting broader smart contract capabilities, could influence whether enterprises build on public networks rather than launching proprietary alternatives.
Raman indicated he plans to publish a detailed critique of private blockchain architectures in the coming weeks.
