Key conclusions
- Ethereum network developers are analyzing 66 proposed changes as part of the Hegotá update planned for 2027.
- The main focus of the work is EIP-8141 (Frame Transactions), which moves the handling of private transactions directly to the protocol, reducing the need for external intermediaries.
- So far, only one change has been officially approved, called FOCIL, intended to limit censorship of transactions by individual block builders.
🔴 Ethereum’s 2027 upgrade narrows to 66 proposals; privacy overhaul in contention Ethereum developers are weighing Frame Transactions (EIP-8141) for the Hegotá upgrade, which would let users customize how transactions are approved, executed, and paid for. Combined with two
Ethereum’s public nature makes the full history of each address publicly available. This is a common risk for companies that process payouts or handle corporate finances that do not want to disclose their cash flows. Until now, ensuring secrecy required the use of external networks and additional infrastructure.
Toni Wahrstätter, a researcher from the Ethereum Foundation, announced in an entry from August 16, 2026, that the list of 66 proposals will be shortened during the next developer meetings to changes that will go to the devnet and testnet networks.
How Frame Transactions changes the functioning of an Ethereum account
The traditional transaction structure requires the user to hold ETH to cover gas costs and use a standard cryptographic scheme. Proposal EIP-8141 breaks this requirement by allowing portfolios to tailor their operating policies to specific operational needs.
In practice, this means the possibility of sponsoring transaction fees by third parties, grouping many operations into one package or changing cryptographic keys without the need to transfer funds to a completely new address.
This solution is part of a broader package of architectural fixes, which also includes EIP-8250 and EIP-8272.
Elimination of bottlenecks and parallel operation
Previous anonymous systems built on Ethereum faced serious performance problems. When many people try to perform a private transaction from one master account, transactions form a rigid queue. One blocked transfer stops all subsequent operations.
Proposal EIP-8250 introduces so-called Keyed Nonces. This mechanism allocates separate counters for independent transactions, eliminating bottlenecks. In turn, EIP-8272 allows you to verify the transaction status against the recent cryptographic record. The transfer will not be rejected if the network status changes while waiting for the block.
Together, these three modifications eliminate the external infrastructure that privacy applications must use today. However, Ethereum itself will not become a completely anonymous network. Regular ETH transfers between standard addresses will remain fully public.
FOCIL mechanism as the only approved change
Despite the wide range of discussions on privacy, the only proposal officially accepted for implementation is currently the FOCIL mechanism. It focuses on fighting censorship at the level of building blocks.
In the current model, the entity submitting the block has full freedom in selecting transactions and can intentionally omit selected transfers. FOCIL requires a group of validators to create a list of transactions that must be included in the next block. This deprives individual builders of the ability to block the operations of specific users.
The remaining 65 proposals – including resistance to quantum computers, changes in validator remuneration and shortening the block generation time – are waiting for core dev decisions. The deadline for submitting new EIPs was August 6.
