Ethereum developers are racing to bring native privacy to the world’s largest smart contract blockchain as investors warn that delays could weaken ETH’s claim as crypto’s default settlement layer.
The pressure has intensified as the market rotates toward privacy-focused assets while Ethereum struggles to hold investor attention amid its current wave of FUD and questions over its identity.
ETH has fallen roughly 30% this year and recently traded near $2,000, even as Zcash has registered double-digit gains during the same period.
That divergence has turned privacy from a long-running cypherpunk goal into a product deadline for Ethereum.
The network still dominates stablecoin settlement, tokenization, decentralized finance, and Layer 2 activity, but its default transparency remains a problem for users and institutions that do not want balances, counterparties, or transaction histories visible in real time.
Tom Dunleavy, head of venture at Varys Capital, said Ethereum’s privacy push is bullish, but only if developers move quickly.
According to him:
“Super bullish on the privacy push for Ethereum, but it needs to happen in a reasonable, under-12-month timeframe, or it effectively doesn’t matter. Ethereum now more than ever is in a race on the product side, and its competition is extremely well-funded, motivated, and has all of the connections Ethereum lacks. Ship or die.”
The warning comes as Ethereum’s market position is already under pressure. GSR Research said blockchain revenue is shifting toward rival networks such as Solana, Tron, and Hyperliquid, while the ETH-to-Bitcoin ratio recently hit its lowest level since mid-2025.
This trend is also reflected in CryptoQuant data, which points to a sharp retreat among retail and mid-tier Ethereum holders.
According to the firm, wallets holding between 100 and 1,000 ETH have nearly halved their balances over the past three years, falling from a 2023 peak of 16.2 million ETH to roughly 8.75 million ETH today.
Larger holders have also begun reducing exposure. Wallets holding between 1,000 and 10,000 ETH, which helped drive Ethereum’s 2024 rally, reportedly started trimming their positions late last year.
Those outflows cannot be directly attributed to demand for privacy. However, they add pressure to Ethereum’s broader narrative at a time when privacy-focused assets are gaining market attention, and investors are questioning what could restore ETH’s momentum.
How privacy became a crypto market trade
The push for Ethereum privacy coincides with a broader market thesis that financial confidentiality will dictate the next major cryptocurrency cycle.
Grayscale Research recently published an analysis arguing that the digital asset sector is on the cusp of a “third wave” of widespread public attention regarding financial privacy.
According to the firm, this shift is driven by the proliferation of stablecoins and blockchain-based applications, as well as the rapid advancement of artificial intelligence. These AI tools, Grayscale warned, introduce new and highly sophisticated methods of financial surveillance.
On public blockchains, balances, counterparties, and transaction histories can remain visible indefinitely.
Grayscale researchers emphasized that the demand for privacy is not solely limited to users seeking full anonymity. Instead, it reflects ordinary preferences for confidentiality in economic life.
Individuals generally do not want their spending history exposed by default, while businesses require confidentiality for supplier payments, payroll, and treasury flows. Institutions similarly view the real-time mapping of their wallet structures as a non-starter.
However, implementing these features involves significant commercial tradeoffs.
Grayscale noted that stronger privacy protections have historically led to weaker market distribution, creating friction with centralized exchange support, regulatory compliance, and wallet integration.
Despite these hurdles, Grayscale Investments Chairman Barry Silbert echoed the report’s sentiment, declaring that the “privacy era” in digital assets has officially commenced.
This narrative shift is already evident in the crypto market, where Zcash's market capitalization has surged by over 900% in the past year, approaching nearly $10 billion. Even Monero, which frequently faces regulatory scrutiny over its use in illicit markets, has doubled in value.
Ethereum co-founder makes play for privacy
Over the past weeks, Ethereum co-founder Vitalik Buterin has pushed the issue back to the front of the network’s technical agenda, calling for developers to “accelerate the cypherpunk privacy reality” after years of privacy research and debate.
His near-term roadmap focuses on three areas, including account abstraction and FOCIL, keyed nonces, and access-layer privacy work.
Together, they are designed to make private Ethereum activity harder to censor, harder to link, and less dependent on trusted infrastructure.
FOCIL, short for fork-choice-enforced inclusion lists, is designed to address transaction censorship.
Today, transactions can sit in a public mempool before they are finalized, giving block builders and other intermediaries visibility into pending activity. That creates openings for exclusion, front-running, and surveillance.
FOCIL would allow a committee of validators to propose lists of transactions that block builders are expected to include.
If builders ignore those transactions, their blocks may be rejected by the network. The mechanism is designed to make it harder to censor transactions, including private transfers, before they reach the chain.
Account abstraction addresses another weakness in Ethereum’s current design. Most users still rely on externally owned accounts controlled by a single private key.
Account abstraction allows accounts to behave more like programmable smart contracts, supporting features such as social recovery, multisignature approval, and fee sponsorship.
For privacy, that flexibility matters because wallet activity can be structured to reduce obvious behavioral patterns. It also makes it easier for applications or relayers to pay fees on behalf of users without forcing every action through the same exposed account model.
Keyed nonces target a narrower but important metadata leak. Ethereum accounts currently use a single counter, known as a nonce, to prevent the same transaction from being replayed. Because that counter increases in sequence, observers can use it to link transactions that might otherwise appear separate.
The proposed fix splits the account counter into different replay domains. That would allow separate types of activity to use different nonce keys, making it harder to link private actions back to the same account through simple sequencing.
Lastly, the most ambitious part of that wider push may be Kohaku, an Ethereum Foundation-backed open-source toolkit designed to bring privacy features into the wallets people already use. The project goes beyond private transfers by targeting the access-layer leaks that expose users before a transaction even settles.
Even if transactions become private, wallets can still leak information when they query the blockchain. Most wallets rely on remote procedure call providers to check balances, read smart contracts, and submit transactions, giving those providers visibility into a user’s IP address, wallet identity, and requested data.
Kohaku is designed to reduce that exposure by giving wallet developers privacy and security components that can be integrated into existing products. Its roadmap includes private sending, safer key management, private reads, and a reference wallet for developers and power users.
The toolkit can also connect wallets to shielded protocols such as Railgun, which is already live on Ethereum, and Privacy Pools, which remains in development.
Ultimately, its goal is to give users private transfers and DeFi access without forcing them to adopt niche tools or move away from wallets they already use.
Ethereum researcher soispoke.eth said the combined package could enable the blockchain network to offer native, trustless, and censorship-resistant private transactions as soon as next year if the proposals ship together.
Why ETH needs to ship privacy features
Crypto lawyer Gabriel Shapiro said these privacy works could help Ethereum compete for institutional tokenization because enterprises need confidentiality for tokenized securities, treasury flows, and DeFi interactions.
That argument goes to the center of Ethereum’s investment case. The network’s advantage has long been its breadth: stablecoins, lending markets, decentralized exchanges, tokenized assets, Layer 2 networks, and developer infrastructure.
However, this breadth alone may not be enough if every financial interaction remains visible by default.
For institutions, public settlement without privacy can be a liability. A company does not want competitors mapping its suppliers. A fund does not want trading routes exposed. A bank does not want clients’ tokenized securities activity to be visible on a public ledger.
Ethereum has the infrastructure to serve those users, but the market is pressing for proof that privacy can reach wallet-level products rather than remain a research agenda.
That is why Dunleavy’s 12-month warning lands with force: Zcash already has the clearest privacy narrative, and Monero remains a major privacy asset despite exchange and regulatory pressure.
At the same time, rival blockchain networks, including Solana, Tron, and Hyperliquid, are capturing market attention while Bitcoin still commands the strongest institutional demand.
Still, Ethereum has the deepest application base in crypto with over $350 billion in assets tokenized on the blockchain, but the market is no longer treating that lead as permanent.
If Hegota introduces usable privacy products within the next year, the feature could strengthen ETH’s role as a settlement infrastructure for both individuals and institutions.
However, if those upgrades remain technical promises, the current privacy trade may continue rewarding assets that made confidentiality their core feature from the start.
