Privacy: The Non-Negotiable Foundation for Next-Generation Blockchains

Forget scalability wars and meme coin mania—the real battle for blockchain's soul is being fought in the shadows. The next generation of distributed ledgers won't be judged by transactions per second, but by their ability to keep those transactions confidential.

The Transparency Trap

Early blockchains sold us on radical transparency—every transaction visible, forever. It was a feature, until it became a bug. Wallet addresses became pseudonymous profiles, spending habits turned into public ledgers, and DeFi positions broadcast to competitors. This isn't financial innovation; it's a gold-plated fishbowl.

Zero-Knowledge Everything

The tech is already here. Zero-knowledge proofs let you verify something is true without revealing the 'something.' Think proving you're over 21 without showing your driver's license, or confirming a transaction is valid without exposing amount, sender, or recipient. It's cryptography that actually delivers on crypto's original promise—trust without exposure.

Regulation's Double-Edged Sword

Privacy tech arrives just as regulators sharpen their knives. The EU's MiCA framework demands identity checks, while the SEC eyes everything that moves. Next-gen chains must walk a razor's edge: private enough for users, transparent enough for compliance. The winners will bake in selective disclosure—privacy by default, auditability when required.

The Institutional On-Ramp

Wall Street won't touch a public ledger. Corporate treasuries, hedge funds, family offices—they need confidentiality that makes Swiss bankers blush. Privacy isn't a niche feature for the paranoid; it's the entry ticket for the trillion-dollar institutional capital waiting on the sidelines. The first chain to solve this gets the keys to the vault.

Beyond Financial Secrecy

This isn't just about hiding crypto punts. Medical research on-chain needs patient privacy. Supply chains require confidential pricing. Voting systems demand anonymous verification. The next internet—the decentralized one—can't be built on a technology that exposes everything by design.

The Bottom Line

Privacy isn't an add-on. It's not a Layer 2 solution or an optional plugin. It's the foundational layer for everything that comes next. Chains that treat it as an afterthought will become digital relics—transparent, traceable, and utterly irrelevant. The future belongs to those who understand that in the digital age, the right to obscurity might be the most valuable right of all. After all, what's the point of disrupting finance if you're just building a panopticon that even central bankers would find excessive?

Privacy Isn’t a Trend. It’s an Ideology

Many are speculating about the reasons behind Zcash’s recent price surge, and the news feed is preoccupied with price movement and predictions of the “privacy meta”.

The public endorsements from mert, ansem, Arthur Hayes, and cobie has undeniably fueled renewed interest, but we have been building in the privacy ecosystem for over ten years.

Regardless of the price outcome of one particular token, privacy isn’t a passing trend. 16z’s 2025 State of Crypto report highlighted a sharp rise in Google search interest for privacy-related terms. Many of today’s crypto enthusiasts, whether from the 2021 bull run or the 2024 memeeuphoria, remain unaware of the big ideological and technical differences that have long shaped the privacy coins ecosystem.

However, privacy coins aren’t built equal.

Privacy Was Always a Feature, Not an Afterthought

The word cryptocurrency literally means “hidden” or “secret” money. However, Satoshi outlined the challenge of wallet tracking in the original bitcoin white paper. He also argued that crypto would be more powerful with strong privacy.

It’s important to note that privacy is not about hiding everything. It’s simply the ability to choose what you want to make public and when. Think about how public trading companies operate, they only reveal their financial data in quarterly reports, and it’s critical they don’t disclose this information beforehand. The same principle applies to individuals and organisations in crypto.

Sygnum Bank’s latest report shows 57% of institutional investors now allocate to crypto for diversification, with LAYER 1s (L1s) absorbing 69% of the capital allocations led by BTC and ETH and rising on-chain activity.

But as institutional adoption grows, so do concerns around transaction privacy, counterparty confidentiality and operational security, areas transparent L1s weren’t built to address.

What Privacy Projects Learned From Monero and Zcash

The two foundational privacy technologies in crypto have historically been CryptoNote and zk-SNARKs. Early privacy coins almost always relied on one of these approaches. Today, however, mainstream L1s like ethereum and Solana are beginning to integrate optional privacy layers, pushing confidentiality into the broader ecosystem rather than leaving it to niche chains.

Monero, the flagship CryptoNote asset, uses ring signatures, stealth addresses, and confidential transactions to hide sender, receiver, and amount by default. Architecturally, it resembles Bitcoin, no smart contracts, no tokens, minimal scripting, and a singular focus on private, fungible peer-to-peer cash. It sacrifices programmability to guarantee privacy.

Zcash, the leading zk-SNARK implementation, encrypts transactions using zero-knowledge proofs so the network can verify validity without revealing data. It also mirrors Bitcoin’s model, offering two address types: transparent “t-addresses,” which function like Bitcoin, and shielded “z-addresses,” which provide full privacy. But because privacy is opt-in, most users remain transparent: roughly two-thirds of transactions still expose all details, shrinking the anonymity set and weakening privacy for everyone.

When privacy requires extra steps, fees, or technical knowledge, most people simply don’t use it, and their transparency harms the anonymity of those who do.

Vitalik’s new Kohaku framework, an attempt to offer default-like privacy with selective disclosure, still relies on opt-in shielding.

However, he noted that relying on backdoors or enabling governments to obtain data by issuing a subpoena is unsafe. He argues that data rarely stays with “trusted officials.” It leaks, it spreads, regimes change, and information collected for safety today can be weaponised tomorrow. The only durable solution is minimising centralised data collection and keeping control in users’ hands.

That’s why privacy by default without any hidden access points for authority is the only path forward.

Build Different

As mainstream L1s experiment with partial privacy layers and optional shielding, it is increasingly clear that a fully private, programmable, multi-asset foundation offers the strongest long-term path for real-world adoption, especially in a world where on-chain surveillance and data risks continue to grow.

A new class of privacy-first multi-asset ecosystems is emerging, built on the simple premise that privacy is not a niche feature, it is a birthright. Unlike earlier systems such as Monero, which offered strong confidentiality at the cost of asset flexibility, these next-generation networks combine cryptographic privacy with the ability to create, hold, and trade entire portfolios of private assets. They enable confidential stablecoins, wrapped private Bitcoin, tokenized securities, and community currencies to coexist and exchange hands without exposing addresses, balances, or behavioural patterns. Privacy happens by default, not as an opt-in chore, avoiding the same failure that defines the modern digital world, where most people choose convenience over protection and, in doing so, shrink the anonymity of everyone else.

And here’s the thing: on Ethereum, the network that pioneered tokenization, ERC-20 tokens are now collectively worth more than ETH itself, with 51% of the network’s secured value allocated to tokens versus 46% to the native asset. Tokens have become as significant, if not more so, than the chains that host them. Stablecoins move billions daily, wrapped assets let Bitcoin holders access DeFi, governance tokens give communities skin in the game. If tokens represent such a massive share of blockchain value and economic activity, then private tokens are the logical next step, and the ability to trade them in private DEXes without KYC, without MEV bots front-running your orders, without broadcasting your financial behaviour to the world, completes the circuit.

But the significance goes beyond financial privacy. When privacy veil tears, whether through loyalty cards that map your life, algorithms that predict your child’s future before you do, or platforms that quietly assemble your digital autobiography, what’s lost isn’t just transaction data.

Privacy-preserving, multi-asset, composable blockchains restore that agency. Through features like auditable wallets, users can choose when to reveal and when to remain unseen, keeping control of their digital identity instead of surrendering it by default. And as mainstream networks experiment with partial or opt-in privacy, it’s becoming clear that only systems designed for confidentiality. The new system can meaningfully protect people in a world where surveillance grows faster than safeguards. If the veil is to be repaired, it won’t be through regulation alone, but through technology that returns privacy to its rightful place as the baseline, not the exception.
