ZR Talks Ep. 12: Why Privacy Is Becoming Mandatory

Episode 12 of ZR Talks begins with Zenrock CTO Sasha Duke reflecting on a lifelong obsession with building software, but it quickly turns into a deeper conversation about where crypto is headed and what breaks if privacy is not rebuilt alongside it.

As institutions move onchain, the panel agrees the industry is still early. Sasha puts it plainly: "We're actually just in the extremely very early innings of this becoming mainstream." The rails exist. Real usage is only starting.

The Cost of Radical Transparency

That shift exposes a growing problem. Public blockchains reveal everything.

Jack Krevitt describes the reality of onchain finance today. "Every time you interact with someone on a blockchain, they know 100% about your financial history." That is not how money has ever worked. People do not share salaries, balances, or net worth just because they made a payment.

Sasha pushes back on the idea that privacy is about hiding wrongdoing. He frames it as safety and basic dignity. "It's quite scary actually how many people get targeted and even kidnapped" because their holdings are publicly visible. Privacy, he argues, is not new. "It's just how cash works."

Introducing Hush, the Privacy Layer of Solana

This is where Hush comes in. Hush is the first and only yielding privacy layer on Solana, designed to function as the privacy layer of Solana itself. Users shield assets into a shared pool, move value privately inside it, and unshield to any address with no onchain link between deposit and withdrawal.

Sasha explains the core mechanism clearly. Once a withdrawal is wrapped in a zero knowledge proof, "there is no way to link a specific deposit to a specific withdrawal event."

Privacy Without Sacrificing Yield

Privacy does not require sacrificing yield. Hush launches with JitoSOL so users can remain private while continuing to earn staking and MEV rewards. Jack explains why this matters. Privacy pools only work if people stay in them. If privacy comes with an opportunity cost, users leave and anonymity weakens.

Why Building Privacy For Scale Matters

The conversation also addresses compliance directly. Jack explains that privacy must coexist with real world constraints. Hush embeds screening at the protocol level so lawful users can transact privately without enabling abuse. "To give privacy for everyone who's abiding by the laws, you also have to make sure you're not giving privacy to people who are not."

As more real assets, income, and institutions move onchain, the need for privacy becomes structural. Adi notes that asset issuers and allocators do not want their full financial activity permanently exposed. Tokenization without encryption does not scale.

The episode closes on a principle that ties everything together. Jack frames privacy not as a feature, but as a requirement for real ownership and autonomy.

"Self sovereignty without privacy is not sovereignty at all."
