Building Bridges: The New Trust Layer for Finance

Recorded live at Ledger’s Paris headquarters during Ledger Op3n, this episode of The Ledger Podcast features Eric Saraniecki, co-founder and Head of Network Strategy at Digital Asset and one of the architects behind the Canton Network. 

Over more than a decade building infrastructure at the intersection of traditional finance and blockchain, Eric has developed a rare perspective grounded in the operational realities of the institutions that move the world’s capital. 

The conversation covers everything from the fundamental fragmentation of financial plumbing, to why privacy is the true differentiator of institutional blockchain, to what 24/7 settlement could mean for global GDP.

“The friction in our capital markets plumbing today is ultimately a tax on productivity and on humanity.” — Eric Saraniecki

The Reconciliation Problem: Why Finance Is Slower Than It Looks

“Something that looks simple to you, the user—send Sébastien some money in a different country—under the hood is many, many systems linked together, built by totally different people.” — Eric Saraniecki

Eric opens by explaining how friction within the financial system is structural. When assets settle, they move across a patchwork of systems that share communication standards but no common logic, meaning every handoff requires reconciliation. He uses the analogy of texting your wife to pick up milk: she can confirm she got the message, but whether she acted on it is a separate question that requires its own verification loop. 

In finance, that loop is called reconciliation, and it is repeated at every node in the chain. Canton’s founding insight was that the destination could not be a single shared ledger. Banks, registers, and exchanges have their own infrastructure requirements, their own governance, and their own regulatory obligations. The goal was to give them the composable interoperability of DeFi while letting each participant remain sovereign over their own environment. 

Privacy Is the Bug That Became Canton’s Core Differentiator

After a decade of building for institutions, Eric identifies privacy as the most consequential unsolved problem in blockchain design. He traces the issue back to the earliest conversations in the space.

“Everyone would always be like, ‘This isn’t really achievable without privacy.’ So the transparency has always been a bug. And yet everybody has replicated that design feature.”  — Eric Saraniecki

For retail crypto, public transparency is acceptable. For institutions moving repo transactions, collateral, or payroll, it is a dealbreaker. Eric is careful to distinguish privacy from anonymity: the goal is not to hide everything from everyone, but to create asymmetric, conditional visibility, where each party in a transaction sees exactly what they need to see and nothing more. 

A bank regulator needs to verify circulation; a counterparty does not need to see the bank’s full balance sheet. Designing those layered, composable privacy guarantees without sacrificing interoperability is, in his words, “a very tricky thing to get right.” Canton’s architecture addresses this directly, and Eric credits it as one of the network’s leading competitive differentiators.

Bringing Banks Onchain: Heterogeneity as a Feature

The conversation also covers Canton’s track record of onboarding major financial institutions, including BNP Paribas and HSBC. What accelerated adoption was Canton’s architecture of heterogeneity: the network does not ask institutions to conform to a single configuration, because no single configuration fits all of them. 

“If you show up and go, ‘There’s one way to do this’, it’s very difficult. The more your products and capabilities match their ability to get the outcome they require, the faster you’ll get to market.”  — Eric Saraniecki

Sébastien draws a parallel to Ledger Enterprise’s own institutional approach of building security infrastructure that adapts to the operational policies of each client rather than forcing them into a predetermined mold. The two companies’ partnership, which includes a deep engineering collaboration, emerged from a shared conviction that privacy and self-custody are prerequisites to institutional adoption.

Advice for Institutions: Do Something, and Partner

Eric’s closing message to financial institutions still on the sidelines is terse and deliberate: “Do something.” But the more nuanced half of his advice is to partner rather than build everything internally. He pushes back on the institutional tendency toward in-house development. Even when a team has the technical capability, the ROI calculus rarely favors reinventing infrastructure that specialists have refined over a decade. 

Key management, node operation, data pipelines, custody security, and policy frameworks are all areas where hard lessons have already been learned in crypto, and where partners like Ledger have built depth that no internal team can replicate quickly.
