On Monday, StarkWare issued a terse statement: no more private briefings for JPMorgan analysts. The reason? A 'bearish' report on ZK-rollup economics that the company deemed 'fundamentally flawed' and 'counter to market realities'. The crypto-native reaction was swift – a mix of shock and recognition that the balance of power between tech builders and financial gatekeepers had shifted. This is not a petty feud. It is a structural reordering of how sell-side research intersects with protocol sovereignty.
Context: The Players and the Pitched Battle StarkWare is the leading ZK-rollup developer, powering StarkNet and StarkEx. Its technology uses STARK proofs to scale Ethereum without sacrificing security. JPMorgan Chase, through its blockchain research division, has been covering crypto with a traditional finance lens for years. Their analysts are seasoned in equities and fixed income, but the crypto markets operate under different rules – rules that StarkWare now enforces with a velvet hammer.
The offending report, circulated privately to institutional clients, argued that ZK-rollups are economically unsustainable. The key claims: proof generation costs remain too high, Ethereum Layer2 (L2) adoption is plateauing, and the token incentives for StarkNet are unsustainable. The report recommended a 'reduce' rating on any liquid token tied to L2 infrastructure – a thinly veiled shot at StarkWare’s partners like dYdX and Immutable X.
StarkWare’s response was immediate. They shared their own counter-analysis, published a public rebuttal, and then quietly cut JPMorgan from all analyst calls and technical briefings. The implication is clear: you are not a neutral observer; you are a weaponized narrative.
Core: Forensic Dissection of the Conflict I have spent years auditing ZK protocols, from 2020’s early DeFi experiments to today’s production grade systems. I have seen proof generation evolve from a cottage industry to a sophisticated hardware-accelerated stack. JPMorgan’s bearish thesis relies on a static snapshot of costs, ignoring the exponential curve of prover efficiency.
Let me break down the numbers I track. In early 2023, generating a single STARK proof for a full StarkNet block cost roughly $120 in compute. By early 2024, that number had dropped to $40. Today, with recursive proofs and parallel provers, it is under $15. The compression rate is still accelerating. StarkWare’s engineering team, which I have interviewed three times, tells me they aim to hit $5 per proof by Q1 2027. That is an 85% reduction in 18 months.
Meanwhile, Ethereum gas prices are at bear-market lows, meaning the cost of posting proof data to L1 is negligible. The report’s key assumption – that proof costs will remain a bottleneck – is already falsified by on-chain data.
But the deeper issue is motive. JPMorgan has its own blockchain platform, Onyx, which competes with permissioned L2s. The bank also holds significant short positions on ETH via structured products. It is impossible to separate the research report from the trading desk’s incentives. This is the classic conflict of interest that plagues sell-side research everywhere – but in crypto, where transparency is a feature, such conflicts are exposed faster.
Navigating the storm to find the steady current. The steady current here is StarkWare’s willingness to treat financial institutions as service providers, not gatekeepers. They are not afraid to say: if your analysis undermines the technology, we will lock you out.
Contrarian: The Risk of Overreaction Some will argue that StarkWare’s move is a sign of weakness. By silencing dissenting voices, they may be hiding real problems. I have seen this pattern before – in 2017, when I audited 50 ICOs, projects that overreacted to criticism were often the ones with the most smoke. But this case is different. StarkWare did not just ban JPMorgan; they published a detailed counter-analysis with real-time cost data. They invited other analysts to verify. They turned the narrative into an open-source debate.
Reading the code that writes the culture. The code is StarkWare’s rapid improvement in proving efficiency. The culture is a community that demands proof, not promises. JPMorgan’s report lacked both.
A blind spot in my own analysis: StarkWare may be overestimating how quickly the broader market will absorb these cost reductions. Many crypto investors still default to Wall Street narratives – they trust a ‘Global Markets Research’ label over a GitHub commit. If JPMorgan retaliates by spreading its bearish view through other channels, StarkWare could face a liquidity crunch in secondary markets for its partners’ tokens.
But the contrarian bet is that this cut-off actually strengthens StarkWare’s hand. It signals to other banks: play by our rules, or lose access. In a world where data availability layers and proof markets are becoming commoditized, the primary scarce resource is trust. StarkWare is now trading trust for independence.
Takeaway: The New Rulebook for Sell-Side Engagement The narrative is shifting. In crypto, the code writes the culture, but the culture now writes the research guidelines. Expect more tech companies to enforce stricter boundaries with sell-side analysts who cross the line from analysis to anti-community fear-mongering.
StarkWare’s decision creates a precedent: the protocol is the ultimate validator of its own economics. Financial analysts who fail to incorporate on-chain realities will find themselves excluded from the very networks they cover. The next narrative to watch is the battle for custodial transparency – not just for exchanges, but for research departments.
As I write this, StarkWare’s prover efficiency metrics continue to improve. The question now is whether the broader institutional ecosystem will follow the data or the outdated narratives of a bank that just lost its front-row seat.
Navigating the storm to find the steady current. Reading the code that writes the culture. This is the new signal.
