Ethereum developers are evaluating a set of proposals for the blockchain's next major upgrade, Hegotá, that could make private transactions easier to execute without relying on external services. The upgrade, expected to ship in 2027, currently has 66 proposals under consideration, with a privacy-focused package drawing particular attention.

The core issue stems from Ethereum's transparent nature: every address is permanent and carries a visible balance, allowing anyone to trace an address's full transaction history. This poses challenges for use cases like payroll or treasury management, where financial privacy is often desired. Currently, applications built on top of Ethereum handle this by using cryptographic proofs, but getting those transactions onto the blockchain still requires extra infrastructure, sometimes routing users through relayers—third-party services that submit transactions on their behalf.

The centerpiece of the privacy package is Frame Transactions, or EIP-8141, which would allow an account to define how a transaction is approved, executed, and paid for, rather than forcing all users through the same process. For an ordinary user, this could mean a wallet where someone else covers the fee, multiple actions are bundled into a single payment, or the cryptography approving a transaction changes without moving to a new account. Toni Wahrstätter, an Ethereum Foundation researcher and co-author of the proposal, highlighted the package's potential in a recent social media post as developers began narrowing Hegotá's scope.

Two related proposals aim to address issues that arise when many people transact privately through the same account. Keyed Nonces, or EIP-8250, would let transactions use separate counters instead of queueing behind a single one, preventing a delayed transaction from holding up others. EIP-8272 would allow a transaction to prove itself against a recent cryptographic record without depending on information that might change while it waits. Together, these three proposals could remove some of the outside infrastructure that privacy applications currently need.

Despite the potential, Ethereum itself would not become private. Sending ETH between two normal addresses would remain as transparent as it is today. The hiding is still performed by applications, which would simply require less external machinery to do so. Frame Transactions is not guaranteed to ship; it has been marked as considered for Hegotá, but that falls short of approval.

So far, only one change has been approved for the upgrade: FOCIL, a censorship-related measure. Currently, the entity assembling a block decides which waiting transactions to include and can omit some. FOCIL would allow a group of network operators to compile a list of transactions that must be included, removing that decision from any single builder. Other proposals under consideration would speed up block production, alter validator earnings, and prepare Ethereum for quantum-resistant cryptography.

The deadline for new proposals passed on August 6. Core developers will decide in upcoming meetings which of the remaining proposals will advance to implementation, devnets, testnets, and ultimately a realistic chance of shipping in 2027.
