Ethereum developers have opened the Platåberget public testnet for the Glamsterdam upgrade, now targeted for the fourth quarter of 2026 after slipping from an earlier first-half timeline. With Glamsterdam still months away, developers have roughly two weeks to narrow 66 competing proposals for the following upgrade, Hegotá, which researchers are now eyeing for 2027.
Ethereum developers are eyeing 2027 for Hegotá as they open Platåberget, a new public testnet for Glamsterdam, the network's next major upgrade now targeted for the fourth quarter of 2026. Earlier this year, the Ethereum Foundation said Glamsterdam was targeting the first half of 2026, with Hegotá expected to follow later in the year. That timeline has since slipped.
Platåberget is designed to run for several months before the upgrade moves to Ethereum's longer-lived Sepolia and Hoodi testnets. Unlike earlier short-lived devnets, it gives developers and users a more stable environment to catch problems before mainnet activation. That testing matters because Glamsterdam introduces breaking changes for tools that assume a hardcoded maximum gas limit, including some wallets, indexers, and gas estimators.
Developers race to narrow 66 Hegotá proposals
On Aug. 16, Ethereum researcher Toni Wahrstätter said network developers are assessing 66 proposals for Hegotá, though only a fraction are likely to receive the implementation work, devnets, and testnets needed for a realistic 2027 release. The Aug. 13 All Core Devs agenda gave developers roughly two weeks to narrow that field: Hegotá's proposed-for-inclusion list is expected to be finalized around Aug. 27, with proposals lacking a clear champion automatically deferred, and client teams have until Sept. 10 to submit preference lists.
FOCIL (EIP-7805) is currently Hegotá's confirmed consensus-layer headliner, addressing censorship resistance by letting committees of validators require certain transactions in blocks. Frame Transactions (EIP-8141) remains under consideration, while dozens of privacy, scaling, validator, and EVM proposals compete for limited implementation capacity, including EIP-8131, EIP-8279, and EIP-8368 for repricing transaction, block, and state-growth costs as Ethereum considers eventually raising its gas limit toward 600 million.
Ethlabs pushes to keep the fork tightly scoped
Ethlabs, an independent research lab launched in June by former Ethereum Foundation contributors and backed by BitMine, SharpLink, and Ethereum co-founder Joe Lubin, is making its case for what survives the cut. The group is championing Quick Slots (EIP-8198) as a step toward faster settlement, and it wants Ethereum to keep raising L1 capacity, arguing scaling constraints prevent some applications from operating on mainnet at all. Ethlabs also strongly backs FOCIL and Frame Transactions but said Frames still needs substantial work for Layer 2 networks.
Because Hegotá is shaping up to be an execution-layer-heavy fork, Ethlabs argued developers should apply a high bar to additional execution-layer EIPs and keep the consensus-layer side relatively light beyond FOCIL and Quick Slots. The group recommended rejecting EIP-8375, which would burn part of the value committed by external builder bids, warning it could encourage side-channel payments. It also placed EIP-8182, which would enable private ETH and ERC-20 transfers, in its lowest priority tier, arguing such a major change with zero-knowledge dependencies should become a headline upgrade if Ethereum eventually decides to pursue it.
