Key Takeaways
- Zcash positions itself as a privacy layer that complements Bitcoin’s monetary design, but its effectiveness might depend on wider shielded adoption.
- Optional privacy could weaken the anonymity set and limits Zcash’s ability to work as a reliable safety system during periods of high surveillance.
- Market cycles have pushed Zcash’s narrative forward faster than real privacy usage, which highlights the gap between speculation and practical protection.
- A private-by-default model remains the central requirement for Zcash to fulfil the insurance role outlined by Naval Ravikant.
Naval Ravikant, the AngelList co-founder and early-stage investor, accelerated a long-running debate about digital privacy when he said Bitcoin is insurance against fiat, and Zcash (ZEC), the native cryptocurrency of Zcash, is insurance against Bitcoin.
The statement captured a growing tension in crypto.
Bitcoin (BTC) can protect holders from inflation, currency devaluation, and state monetary control. But it also exposes every transfer on a permanent public ledger. Analytics companies and regulators built entire frameworks around those traces. The system offers monetary freedom at the cost of transactional openness.
Ravikant’s framing positions Zcash as a hedge against that visibility. Zcash uses cryptographic privacy to remove the traces that sit at the center of Bitcoin’s design. The idea creates a layered protection model where Bitcoin shields users from fiat risk and Zcash shields them from Bitcoin’s transparency.
As of November 2025, Zcash’s shielded supply has reached 4.9 million ZEC.
Quinten van Welzen, Head of Strategy and Communications at Zano, told CCN why the privacy debate keeps returning, why optional privacy models struggle, and what privacy coins must solve before the insurance narrative holds real weight.
This article explains how Zcash’s transparency can create new risks in the Bitcoin economy, and how privacy technology connects to evolving market narratives.
Zcash’s Dual Address System: Transparent vs. Shielded Transactions
Privacy and monetary structure shape what insurance means in the cryptocurrency space. Zcash protects confidentiality through zero-knowledge proofs (ZKP). Bitcoin protects monetary stability through hard-capped issuance and decentralization. Each reduces a different form of risk. A system that functions as insurance must lower exposure to a specific threat. In crypto:
- Bitcoin lowers exposure to fiat inflation through fixed supply.
- Zcash lowers exposure to surveillance through private transactions.
- Both create layers of protection rather than one single shield.
This distinction sets up the practical question: Do users actually benefit from the privacy insurance that Zcash offers? The answer might depend on how often users choose the private option in real transactions.
According to Quinten van Welzen, “Zcash uses two address types: transparent t-addresses that behave like Bitcoin, and shielded z-addresses that use zk-SNARKs to hide sender, receiver and amount. Today the shielded pool consistently holds between 25–30% of supply, and roughly two-thirds of transactions still occur transparently.”
He noted that “the gap between trading enthusiasm and actual shielded usage shows that optional privacy does not translate into privacy adoption at scale.”
Privacy also depends on user behavior. Van Welzen told CCN that most privacy systems fail when they rely on optional features.
He said “when privacy requires extra steps, extra costs, or deeper technical understanding, users tend to fall back to whatever is simplest.”
His point shows that insurance in crypto depends on usability. A design that protects users by default becomes a stronger form of insurance than one that requires them to opt in.
Balancing Visibility and Protection: The Insurance Dilemma in Zcash
Bitcoin’s structure delivers open verification, but that same structure can expose activity that anyone could trace.
As of July 2025, balances held by illicit entities in Bitcoin (BTC), Ethereum (ETH), and stablecoins totaled nearly $15 billion (a 359% year-over-year increase) highlighting the rising traceability of transparent chains.
This tension explains why privacy became a central theme in the current Zcash narrative and why the debate over transparent blockchains keeps resurfacing.
Van Welzen told CCN that speculation often grows faster than real privacy usage.
He said “a lot of the renewed interest is memetic and narrative driven, similar to Bitcoin’s appeal. Zcash has the 21 million cap, proof-of-work (PoW), and a cypherpunk framing as ‘encrypted Bitcoin’.”
And continued, stating that “the price surge and the listing of ZEC perpetuals on Hyperliquid amplified trading activity. But real privacy usage still lags because opt-in models don’t work for most people. What looks like rising privacy demand at the market level is often traders speculating on the narrative rather than users engaging with privacy features.”
This split between visibility and protection shapes the insurance argument around Zcash. Bitcoin exposes all activity by default. Zcash promises privacy, but optional features slow adoption. The result is a market where enthusiasm moves fast, while real privacy behavior grows at a slower pace.
What Zcash Insures Users Against
The privacy limitations of Bitcoin frame Naval Ravikant’s argument that Zcash acts as a form of insurance. Bitcoin secures monetary policy, but its transparent ledger exposes every transfer, which can potentially allow investigators to map identities over time.
This tension grows as surveillance expands across the crypto economy. Ravikant’s framing treats Zcash as protection against that visibility.
Van Welzen explained the idea to CCN. He said “Satoshi highlighted the challenge of wallet tracking in the original Bitcoin white paper, and he argued that crypto is more powerful with strong privacy. Zcash positions itself as ‘encrypted Bitcoin’, which speaks directly to that concern at a time when on-chain surveillance from firms like Chainalysis and even independent investigators is expanding.”
His point reflects how public data allows deep analysis of user behavior.
In November 2025, Zcash (ZEC) surged 1,500% to a peak of $750 per coin, outperforming Bitcoin (BTC), which traded near $125,000 amid broader market pressures and ETF inflows.
Van Welzen added that “Zcash offers a parallel system where users have access to strong cryptographic privacy instead of relying on heuristics and best efforts on a transparent chain. The realism of the ‘insurance’ framing depends on adoption of shielded usage. If most activity continues to happen in transparent addresses, the practical strength of that insurance is limited.”
The Limits of Optional Privacy in Crypto Design
The discussion around Zcash’s insurance role also connects to broader questions about privacy architecture.
Optional systems rarely achieve meaningful protection because the responsibility shifts to the user.
Van Welzen argued that this structure creates a weak anonymity set and limits real-world effectiveness.
The lesson appears consistent across the privacy space. Van Welzen’s considers that:
- User choice: Privacy collapses when protection depends on optional behavior because only a small group opts in.
- Low participation: Anonymity weakens when few users choose shielded activity, which reduces protection even for those who do.
- Default settings: Privacy by default solves the structural problem by securing all activity automatically.
These limits shape the next question: whether Zcash could function as a real fallback if Bitcoin’s transparency becomes a liability.
Could Zcash Ever Become Bitcoin’s Real Backup Plan?
A backup plan could protect users the moment surveillance pressure increases. That would require automatic privacy and a large anonymity set. Van Welzen told CCN that Zcash does not meet those conditions today because most activity remains outside the shielded pool, which limits the system’s strength during periods of stress.
Trading patterns reinforce the gap. Zcash outperformed Monero and Litecoin in volume, yet shielded usage stayed flat.
Van Welzen noted that this reflects speculation rather than real engagement with Zcash’s privacy features.
Key constraints shaping Zcash’s fallback potential reflect Van Welzen’s concerns:
- Small shielded pool: The anonymity set is too small for a real fallback because most of the supply remains transparent.
- Transparent activity dominating usage: Two-thirds of transactions still use t-addresses that behave like Bitcoin.
- Speculative interest without matching privacy use: The recent surge came from narrative trading, not from increased shielded activity.
Therefore, Van Welzen warned that a fallback chain must deliver immediate confidentiality, and optional privacy cannot provide that during moments of heightened surveillance.
The Roadmap to Default Privacy: How Zcash Can Fulfill the Insurance Promise
Van Welzen told CCN that Zcash’s current structure falls short because privacy still depends on user action.
Zcash can only deliver the “insurance” role described by Naval Ravikant if privacy becomes the standard path rather than an optional feature. The system needs a large anonymity set, seamless shielded usage, and protections that operate without extra steps.
He said, “Across the space, we have seen that optional privacy does not work in practice. Users generally do not opt in, even when it protects them. When only a minority use the private path, their anonymity set becomes smaller, which also weakens the privacy of those who did try to shield themselves.”
His point shows why Zcash must shift from optional shielding to a model where privacy is activated by default.
Van Welzen also highlighted what this future requires.
He said, “The most important design shift is to make privacy the default rather than a special mode. Privacy by default means that everyone benefits from strong cryptographic protections automatically, without needing to learn complex tools or make a decision for every transaction.”
He pointed to selective-disclosure designs like Zano’s Auditable Wallets and Vitalik’s Kohaku framework as examples of architectures that keep privacy strong while still allowing controlled transparency when necessary.
Privacy by Default: The Shift Zcash Must Make
Zcash’s future depends on whether its privacy layer can function at full strength without user intervention. A network that relies on manual shielding exposes most activity and weakens its own anonymity base. This limits Zcash’s ability to act as a reliable protection system in moments when transparent chains become risky.
Van Welzen described the structural constraint directly. He said “the shielded pool is the core of the ‘safety layer’ idea,” and the imbalance reduces the collective privacy of the network and restricts the protection Zcash can offer during periods of heightened scrutiny.
A meaningful shift requires privacy to operate automatically across the full network. Van Welzen outlined the requirement clearly: “shielded usage must become the default experience rather than the specialised one” because “privacy systems only work when the anonymity set is large.”
Selective-disclosure systems such as Auditable Wallets and Kohaku-style frameworks support this direction by allowing transparency when necessary without weakening the underlying protection.
Zcash’s ability to stand as a credible insurance layer depends on this change. Only a private-by-default design can transform its cryptographic tools into consistent, dependable protection during real-world stress.
FAQs
Naval Ravikant is the co-founder of AngelList and an influential early-stage investor known for shaping discussions around decentralization, digital freedom, and crypto governance. His views carry weight in the industry because founders, investors, and policymakers often treat his commentary as a signal for long-term technological direction.
Zcash would need a larger shielded pool, broader wallet support for private-by-default transactions, and consistent real-world usage that reflects its privacy design. These conditions would expand the anonymity set and strengthen its role as a protection layer.
Privacy systems weaken when users avoid shielded transactions. When only a fraction of activity takes place in the private layer, the anonymity set becomes smaller, which makes network-level privacy less effective.
