Ethereum Weighs Hegotá Upgrade With Protocol-Level Privacy and Censorship Resistance Features

Ethereum developers are considering a major expansion of the network's privacy capabilities as part of the upcoming Hegotá upgrade, with proposed changes that could allow users to conduct more private transactions while strengthening protections against censorship.

The upgrade could mark an important shift in Ethereum's long-term development strategy. Rather than relying entirely on external privacy applications, developers are exploring ways to make privacy features part of the underlying protocol itself.

Proposals under consideration include private ETH and ERC-20 transfers, new transaction formats, parallel transaction sequences and mechanisms designed to make it harder for block builders to prevent valid transactions from being included on the network. Ethereum's official privacy roadmap identifies these areas as part of a broader effort to make privacy a structural feature of the network rather than an optional add-on.

What Is the Hegotá Upgrade?

Hegotá is expected to follow Ethereum's Glamsterdam upgrade and is currently targeted for 2027, although Ethereum developers emphasize that upgrade timelines can change.

The Ethereum Foundation has already selected Fork-Choice Enforced Inclusion Lists (FOCIL) as the consensus-layer headliner for Hegotá. Other proposals, including privacy and account-abstraction improvements, remain under consideration.

The name Hegotá combines the previously proposed Heka or Heze naming concept with Bogotá. Ethereum developers have been using star-inspired names for network upgrades, with Hegotá now established as the name for the fork following Glamsterdam.

While Hegotá is still under development, its current proposals indicate that privacy and censorship resistance could become some of the network's most important priorities.

Ethereum Wants Privacy at the Protocol Level

Ethereum transactions are currently highly transparent. When a user sends ETH or interacts with a smart contract, information about the transaction can generally be viewed publicly on the blockchain. Wallet addresses, transaction amounts and contract interactions can be analyzed by anyone with access to blockchain data.

That transparency can be useful for verification, but it can also create significant privacy concerns. In practice, blockchain-analytics firms routinely mine this public data to profile addresses and link activity across services, which means routine onchain use can expose more about a person than many users assume.

Ethereum's privacy roadmap identifies three broad areas of development:

• Private reads would make it harder for outside parties to determine what information a user is accessing.
• Private writes would protect transactions from metadata leakage and censorship.
• Private proving would allow users to demonstrate certain facts about themselves without exposing unnecessary personal information.

The goal is to give users greater control over what information they reveal while maintaining Ethereum's ability to verify transactions.

Private Transactions Could Become Native to Ethereum

One of the most notable proposals being considered for Hegotá is EIP-8182, which would introduce protocol-level shielded pools for private ETH and ERC-20 transfers. The proposal is designed to make it possible to transfer assets without publicly exposing the full relationship between the sender and recipient in the same way standard Ethereum transactions do.

Ethereum's official privacy roadmap describes the proposed system as a shared shielded pool built directly into the protocol. The approach is intended to reduce fragmentation among existing privacy solutions and potentially improve anonymity by creating a larger common privacy set.

The design also has precedent in the wider industry: Zcash popularized shielded transactions after its 2016 launch, using zero-knowledge proofs to let users transfer funds without publicly exposing amounts or counterparties. EIP-8182 would bring a comparable capability directly into Ethereum's base layer rather than leaving it to separate chains or applications.

This would represent a major change from Ethereum's current model, where users who want greater transaction privacy generally have to rely on specialized wallets, applications, privacy protocols or Layer 2 networks.

Self-Funded Privacy Transactions

Another important component involves the way users pay transaction fees.

EIP-8141, known as Frame Transactions, is being considered for Hegotá. The proposal would allow accounts to use external contracts to authorize or cover gas fees.

That feature could be particularly important for privacy applications. A privacy tool could potentially pay transaction costs on behalf of a user, reducing the need for the user's publicly identifiable wallet address to directly fund the transaction.

Ethereum's privacy roadmap notes that Frame Transactions could allow privacy-preserving signature schemes and gas-fee abstraction without exposing the user's address onchain in the traditional way. This is one reason the concept of self-funded or sponsored privacy transactions has attracted attention.

The objective is not simply to hide transaction details. It is also to reduce the metadata that can connect a private transaction back to a specific public wallet.

FOCIL Could Strengthen Censorship Resistance

Privacy alone does not guarantee a private transaction will reach the blockchain. A transaction can still be delayed or excluded before it is included in a block. This is where FOCIL becomes important.

Fork-Choice Enforced Inclusion Lists would require block proposers to include transactions drawn from aggregated local inclusion lists. If a block builder attempts to censor a transaction that should have been included, validating nodes could reject the proposed block.

The system is designed to distribute control over transaction inclusion rather than allowing a small number of block-building entities to determine which transactions reach the chain. Ethereum developers have increasingly focused on this issue as block-building infrastructure becomes more sophisticated and concentrated. The concentration is measurable: under Ethereum's current proof-of-stake design, most blocks are produced through the MEV-Boost marketplace, where public dashboards have consistently shown a small set of builders constructing the majority of blocks. The risk has also surfaced in practice, as public dashboards showed a significant share of Ethereum blocks for a time excluding transactions that touched the Tornado Cash mixer after U.S. sanctions were imposed on it in 2022, an episode developers frequently cite when arguing for protocol-enforced inclusion.

Privacy and Censorship Resistance Are Connected

Ethereum's developers increasingly view privacy and censorship resistance as related problems. A transaction can use sophisticated cryptography to protect its contents, but that protection becomes less meaningful if centralized infrastructure can simply prevent the transaction from being included.

The proposed Hegotá features attempt to address both sides. Frame Transactions could provide greater flexibility for privacy-preserving transactions, while FOCIL could help protect those transactions from selective censorship once they enter the network's transaction pipeline. Ethereum's official roadmap describes these mechanisms as addressing different failure points in the privacy process.

Keyed Nonces Could Improve Transaction Privacy

Another proposal under consideration is EIP-8250, which introduces keyed nonces for Frame Transactions.

Ethereum's existing account model uses a sequential nonce system. Each transaction from an account generally follows an ordered sequence. While this works reliably, it can also create privacy problems because observers can connect multiple transactions to the same account.

Keyed nonces would allow an account to maintain multiple transaction sequences simultaneously. That could make it harder for observers to correlate separate private activities back to a single originating account. For users seeking greater financial privacy, this could become an important technical improvement.

Ethereum's Broader Privacy Push

The Hegotá proposals fit into a larger effort within Ethereum to make privacy a fundamental property of the network. The Ethereum Foundation has explicitly identified privacy, censorship resistance, open-source development and security as core principles that should remain protected as the protocol evolves. Ethereum co-founder Vitalik Buterin has likewise repeatedly identified privacy as one of the network's most important unfinished goals in his public roadmap writings.

The foundation's current privacy roadmap also makes clear that development is spread across numerous teams rather than controlled by a single organization. That decentralized development process means proposals must go through technical review, testing and community coordination before they can become part of the Ethereum protocol.

What Hegotá Could Mean for Ethereum Users

If the proposed privacy features eventually make it onto Ethereum mainnet, users could gain access to privacy tools that are significantly more integrated into the network. Instead of relying exclusively on separate applications, users could potentially use native protocol features for private transfers, alternative transaction authorization and more flexible fee payment.

That could have implications beyond individual users. Businesses, financial institutions and decentralized applications could benefit from greater control over sensitive transaction information while still maintaining Ethereum's verifiability.

At the same time, privacy improvements are likely to attract regulatory attention because blockchain transparency has historically been an important component of compliance and transaction monitoring. That tension is not hypothetical: the U.S. Treasury's Tornado Cash sanctions were ultimately lifted in 2025 following a court ruling, but the intervening years showed how regulatory actions can quickly ripple through onchain activity. Ethereum's developers therefore face the challenge of balancing privacy, security, usability and regulatory considerations.

Hegotá Remains a Work in Progress

Despite the significance of the proposals, Hegotá should not be viewed as a finished upgrade. Ethereum developers are still evaluating which features should ultimately be included. The official roadmap currently identifies FOCIL as the consensus-layer headliner, while several privacy-related EIPs remain under consideration. The final scope could therefore change as developers test the technology and evaluate security risks. The concrete milestones to watch are the formal inclusion decisions for the individual EIPs in Ethereum's core developer calls, the emergence of dedicated devnets testing features such as FOCIL and the shielded pool, and eventual testnet rollouts ahead of any mainnet activation.

Still, the direction is increasingly clear. Ethereum is working toward a future in which users can interact with the blockchain while revealing less information, paying fees more flexibly and gaining stronger protection against transaction censorship. If those goals are successfully implemented, Hegotá could become one of Ethereum's most important upgrades for privacy and user sovereignty.

For now, the proposed changes signal a significant evolution in Ethereum's roadmap: privacy is no longer being treated solely as an application-layer feature. Developers are increasingly exploring how it can become part of the network itself.
