Ethereum developers are racing to introduce native privacy to the world’s largest smart contract blockchain, as investors warn that delays could weaken ETH’s case as the cryptocurrency’s default payment layer.
While Ethereum is struggling to gain investor attention amid the current wave of FUD and questions surrounding its identity, pressure is increasing as the market moves towards privacy-focused assets.
Despite Zcash posting double-digit gains over the same period, ETH has fallen about 30% this year and recently traded near $2,000.
This disconnect has turned privacy from a long-standing goal of cypherpunks to a product deadline for Ethereum.
The network still dominates stablecoin payments, tokenization, decentralized finance, and layer 2 activity, but its default transparency remains an issue for users and institutions who don’t want real-time visibility into their balances, counterparties, or transaction history.
Tom Dunleavy, head of venture at Vallis Capital, said he is bullish on Ethereum’s privacy push, but only if developers act quickly.
According to him:
“I’m very bullish on Ethereum’s privacy push, but it has to happen within a reasonable period of time, 12 months or less, otherwise it doesn’t really matter. Ethereum is now competing more than ever on the product side, and its competitors are very well-funded, very motivated, and have all the connections that Ethereum lacks. Get out or die.”
The warning comes as Ethereum’s market position is already under pressure. GSR Research said that while blockchain revenues are shifting to competing networks such as Solana, Tron, and Hyperliquid, the ETH to Bitcoin ratio recently reached its lowest level since mid-2025.
This trend is also reflected in CryptoQuant data, showing a sharp pullback for retail and mid-sized Ethereum holders.
According to the company, the balance of wallets holding 100 to 1,000 ETH has nearly halved over the past three years, from a peak of 16.2 million ETH in 2023 to around 8.75 million ETH today.
Larger holders are also starting to reduce their exposure. Wallets holding between 1,000 and 10,000 ETH, which were the driving force behind Ethereum’s 2024 rally, reportedly began reducing their positions late last year.
These outflows are not directly attributable to the demand for privacy. But they add pressure to Ethereum’s broader story at a time when privacy-focused assets are gaining market attention and investors are wondering what could restore ETH’s momentum.
How privacy became a cryptocurrency market transaction
Ethereum’s push for privacy is consistent with broader market wisdom that financial confidentiality will dictate the next major crypto cycle.
Grayscale Research recently published an analysis claiming that the digital asset sector is in the midst of a “third wave” of increased public attention regarding financial privacy.
The company says this change is being driven by the proliferation of stablecoins and blockchain-based applications, as well as rapid advances in artificial intelligence. Grayscale warned that these AI tools introduce new and highly sophisticated financial surveillance techniques.
On a public blockchain, balances, counterparties, and transaction history can remain visible indefinitely.
Grayscale researchers emphasized that the demand for privacy is not limited to users seeking complete anonymity. Rather, it reflects a general preference for secrecy in economic life.
Individuals generally do not want their spending history to be made public by default, while businesses require confidentiality around supplier payments, payroll, and financial flows. Financial institutions are similarly new to real-time mapping of wallet structures.
However, implementing these features comes with significant commercial trade-offs.
Grayscale noted that historically stronger privacy protections have led to weaker market distribution, creating friction with centralized exchange support, regulatory compliance, and wallet integration.
Despite these hurdles, Barry Silbert, chairman of Grayscale Investments, echoed the report’s findings, declaring that the “era of privacy” in digital assets has officially begun.
This change in narrative is already evident in the crypto market, with Zcash’s market capitalization surging over 900% in the past year and approaching $10 billion. Even Monero, which has frequently come under regulatory scrutiny over its use in illegal markets, has doubled in value.
Ethereum co-founder takes action to protect privacy
Over the past few weeks, Ethereum co-founder Vitalik Buterin has called on developers to “accelerate the reality of cypherpunk privacy” after years of privacy research and debate, pushing the issue to the forefront of the network’s technical agenda.
His near-term roadmap focuses on three areas, including account abstraction and FOCIL, keyed nonces, and access layer privacy work.
Together, these are designed to make private Ethereum activity harder to censor or link to, and less dependent on trusted infrastructure.
FOCIL stands for fork-choice-enforced inclusion list and is designed to address transaction censorship.
Transactions can now be stored in a public memory pool before they are completed, allowing block builders and other intermediaries to see pending activity. That creates room for exclusion, front-line attacks, and surveillance.
FOCIL allows a committee of validators to propose a list of transactions that they are expected to include in a block builder.
If the builder ignores these transactions, the block may be rejected by the network. This mechanism is designed to make it difficult to censor transactions involving 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 like programmable smart contracts and support features such as social recovery, multi-signature authorization, and fee sponsorship.
That flexibility is important when it comes to privacy, as wallet activity can be structured to reduce obvious behavioral patterns. It also makes it easier for applications and intermediaries to pay fees on behalf of users without forcing all actions through the same exposed account model.
Keyed nonces target narrow but important metadata leaks. Currently, Ethereum accounts use a single counter called a nonce to prevent the same transaction from being executed again. Because this counter increments sequentially, observers can use it to link transactions that may appear to be separate.
The proposed fix splits the account counter into different replay domains. This allows different types of activities to use different nonce keys, making it difficult to relink private actions to the same account through a simple sequence.
Finally, the most ambitious part of its broader push may be Kohaku, an Ethereum Foundation-backed open-source toolkit designed to build privacy features into the wallets people already use. This project goes beyond private transfers by targeting access layer leaks that put users at risk before transactions are resolved.
Even if a transaction is private, information can be leaked when the wallet queries the blockchain. Most wallets rely on remote procedure call providers to check balances, read smart contracts, and send transactions, allowing these providers to know your IP address, wallet ID, and requested data.
Kohaku is designed to reduce that risk by providing wallet developers with privacy and security components that they can integrate into their existing products. Its roadmap includes private sends, more secure key management, private reads, and a reference wallet for developers and power users.
The toolkit can also connect wallets to shielded protocols already running on Ethereum, such as Railgun and Privacy Pool, which is in development.
The ultimate goal is to provide private money transfers and DeFi access without forcing users to adopt niche tools or leave the wallets they are already using.
Ethereum researcher soispoke.eth said that if the proposals are shipped together, the integrated package could enable blockchain networks to offer native, trustless and censorship-resistant private transactions, as early as next year.
Why ETH needs to include privacy features
Cryptocurrency lawyer Gabriel Shapiro said these privacy measures could help Ethereum compete in institutional tokenization, as companies require confidentiality around tokenized securities, financial flows, and DeFi interactions.
This argument is central to the Ethereum investment case. The advantage of this network is its breadth, including stablecoins, lending markets, decentralized exchanges, tokenized assets, layer 2 networks, and developer infrastructure.
However, this coverage may not be sufficient if all financial interactions remain visible by default.
For educational institutions, public payments without privacy can be a liability. Companies don’t want competitors to map their suppliers. Funds do not want their trading routes exposed. Banks do not want their customers’ tokenized securities activity to appear on the public ledger.
Ethereum has the infrastructure to serve these users, but the market is looking for evidence that privacy can extend beyond a research topic to wallet-level products.
That’s why Dunleavy’s 12-month warning stands. Zcash already has the clearest privacy statements, and Monero remains a leading privacy asset despite exchange and regulatory pressures.
At the same time, while competing blockchain networks such as Solana, Tron, and Hyperliquid are gaining market attention, Bitcoin remains the most sought after by institutional investors.
Still, while Ethereum has the deepest application base of any cryptocurrency, with more than $350 billion in assets tokenized on the blockchain, the market no longer treats its lead as permanent.
If Hegota introduces privacy products available within the next year, this feature could strengthen ETH’s role as a payments infrastructure for both individuals and institutions.
However, if these upgrades remain technical promises, current privacy deals are likely to continue to reward assets that made confidentiality a core feature from the beginning.
