Ethereum is for building bridges not walls
2026-05-09 –, Sladkovský Stage

Institutions built permissioned chains because they had no choice. Public blockchains like Ethereum offered no privacy and compliance was unsolvable. That's changing. FHE and ZK proofs fundamentally alter the calculus. The question now is whether we build bridges, or keep building walls that cost this industry its credibility.


I've spent the better part of my career at the intersection of traditional finance and emerging technology, first at fintech, then at Goldman Sachs, where I worked across structured products and capital markets, and later in Web3, leading engineering at one of the largest onchain treasury managers in the space.

That vantage point gave me a front-row seat to a recurring frustration: institutions that genuinely wanted to engage with public blockchain infrastructure kept hitting the same wall. The technology does not lack ambition, but it lacked two things they can not compromise on: privacy and compliance.

Canton was built as a response to this problem, and it proves the appetite to work onchain is real. But it is a walled garden, and walled gardens reinforce the narrative that crypto cannot be trusted with serious financial infrastructure.

I don't want that narrative to become permanent. It was earned, but the tools to change it now exist. FHE is moving from research to production. ZK proofs are being deployed in regulated contexts. Selective disclosure (the ability to prove compliance without revealing underlying data) is no longer theoretical.

My motivation for speaking on this is simple: I'm building infrastructure that depends on this being true. And I think the people in our conferences — founders, allocators, policymakers — need to have an honest conversation about what it actually takes to bridge institutional and public blockchain infrastructure, beyond the marketing claims on both sides.
