Ethereum Hegotá Evaluates Native Privacy Transaction Components, Protocol Reduces Friction, Nodes Bear Costs
Toni Wahrstätter, a member of the Ethereum Foundation's protocol architecture team, proposed to incorporate Frame Transactions into Hegotá, alongside the established FOCIL, as a key upgrade feature; this proposal has not yet been finalized by core developers.
Currently, Hegotá has officially scheduled only EIP-7805, which is FOCIL. This mechanism allows the validator committee to publish a list of transactions to be included, preventing block proposers from arbitrarily excluding eligible pending transactions, thereby enhancing the network's censorship resistance.
Frame Transactions correspond to EIP-8141, which aims to separate transaction authorization, execution, and Gas payment into a programmable framework, supporting alternative signature schemes, key rotation, and third-party Gas payment; it is still in the "consideration for inclusion" stage, with developers comparing it against EIP-8130.
EIP-8250 proposes Keyed Nonces, replacing a single transaction nonce with a set of nonce keys managed by the protocol and a sequence number, allowing the same account to send Frame Transactions in different nonce domains in parallel, avoiding one pending transaction from blocking other independent transactions.
EIP-8272 allows Frame Transactions to read recent state roots, verifying recent cryptographic commitments without accessing mutable storage; combined with Frames and Keyed Nonces, it can construct transaction structures where the fee is paid by the fund pool itself, reducing reliance on intermediary payers. This capability is a fundamental primitive and does not equate to Ethereum enabling transaction privacy by default.
Wahrstätter also listed scalability candidates, including unifying transaction calldata lower limits, BAL byte lower limits, CPSB recalibration, BAL Sidecars, optional execution proofs, and Quick Slots; among these, the CPSB proposal aims to push the Gas limit to around 500 million to 600 million, while Quick Slots intends to shorten block slot times from 12 seconds to 10 seconds. These proposals are all under review and have not yet been confirmed for inclusion in Hegotá.
In terms of market mechanisms, the direct effect of FOCIL is to limit the transaction filtering power of block builders and proposers, benefiting users, privacy applications, and on-chain settlement protocols that rely on permissionless transaction inclusion; if Frame and related privacy primitives are adopted, they could reduce reliance on relay parties for account abstraction, Gas payment, and privacy protocols. The costs will be borne by validators, clients, and block building infrastructure: more complex transaction validation, state processing, propagation requirements, and potentially higher hardware loads, especially when higher Gas limits and faster slot times are pursued simultaneously.

Ethereum's past transaction model centered around EOAs, ECDSA signatures, and a single incrementing nonce; ERC-4337 achieved account abstraction externally through Bundlers and EntryPoints, while EIP-7702 introduced temporary code delegation for EOAs in the Pectra route. The historical position of Frame Transactions attempts to further embed authorization, execution, nonce management, and payment logic at the protocol level, rather than being pieced together by wallets, Bundlers, or application layer relayers.
Capital and resource pathways focus on "who pays the execution costs, who controls the transaction entry." Traditional privacy pools or smart accounts that require external Relayers to pay Gas will have users' transaction submissions and fee payments dependent on intermediaries' inventories, compliance judgments, and online statuses. EIP-8272 allows transactions to reference recent state roots, EIP-8250 provides parallel nonce domains, and Frame carries programmable validation and payment; the goal of this combination is to enable the fund pool to settle fees using its own assets, shifting payment resources from centralized service providers to protocol rules.
This can be contrasted with privacy protocols like Tornado Cash and Railgun: the former relies on zero-knowledge proofs and on-chain fund pools, while the latter offers a more flexible private balance model, but users still face visibility issues regarding public Gas payments and transaction inclusion when entering the mainnet. FOCIL addresses "whether valid transactions can be included in blocks," while Frame and Recent Roots address "how to verify and pay for transactions"; neither can directly hide addresses or amounts, but they may reduce privacy applications' reliance on external infrastructure. Hegotá is currently in the candidate convergence stage, with only FOCIL officially scheduled, and this combination should not be viewed as confirmed upgrade content.
Essentially, this represents a reconstruction of the industry chain: Ethereum seeks to shift some control over transaction entry from wallet service providers, Bundlers, Relayers, and block builders back to the protocol layer. The mechanism at play is that the more complex the transaction expression, the easier it is for off-chain intermediaries to become centralized nodes for fee payment, sorting, and review; if the protocol provides native programmable transactions, parallel nonces, recent state verification, and mandatory inclusion rules, applications can reduce their functional reliance on these nodes. Meanwhile, higher Gas limits and shorter block cycles will push performance pressure onto node operators, and the degree of decentralization will depend on client optimization and hardware costs.
