- Today marks the scheduled activation of Glamsterdam on Sepolia, accompanied by a 200M gas-limit test for Ethereum.
- By introducing block-level access lists and enshrined proposer-builder separation, Glamsterdam aims to optimize Ethereum’s block validation and production.
Ethereum is gearing up to trial a 200 million gas limit on the Sepolia testnet as the rollout of the Glamsterdam upgrade enters its next phase today. This update arrives via Prysm v7.2.1, which was launched by Offchain Labs on October 5. The software introduces the Sepolia gas-limit schedule and establishes 200 million as the default gas ceiling for validators following the Gloas fork.
Additionally, the latest Prysm update modifies data column management by enabling partial data columns by default. Nodes are now permitted to gossip individual cells rather than full data columns. Furthermore, Prysm incorporates new configuration settings tailored for Gloas builders, encompassing builder URLs, minimum bids, and builder bid timeouts.
This 200 million gas configuration represents more than a threefold increase over Sepolia’s prior 60 million gas limit. According to Prysm’s release notes, the new schedule goes live at epoch 353,024, aligning with the Gloas fork parameters set for Sepolia. Validators running Prysm v7.2.1 will apply the 200 million limit automatically, though operators retain the option to specify an alternative limit via proposer settings or the keymanager API.
Glamsterdam Reaches Sepolia Today
Activation of the Glamsterdam upgrade on Sepolia is slated for October 6 at 13:53:36 UTC, aligning with epoch 353,024 and slot 11,296,768. The upgrade integrates Amsterdam execution-layer modifications alongside Gloas consensus-layer changes.
Key features of the upgrade include enshrined proposer-builder separation (ePBS) and Block-Level Access Lists (BALs). BALs track the storage locations and accounts accessed throughout a block, enabling clients to execute transaction validation and state reads more efficiently in parallel. Additionally, Glamsterdam adjusts gas accounting rules for calldata, state access, state creation, and access lists.
It is important to note that this 200 million gas trial is restricted solely to Sepolia and does not alter the gas limit on the Ethereum mainnet. The Ethereum Foundation has not yet disclosed mainnet or Hoodi activation schedules.
On the market front, CoinMarketCap data indicates that ETH is changing hands near $2,714, holding a market capitalization close to $331 billion and a 24-hour trading volume exceeding $10.2 billion. Over the preceding 24 hours, ETH has experienced a decline of roughly 0.8%.
Historical figures show that ETH finished October 5 at $2,710.42, following a recent September peak of $2,785 achieved on September 23.
From a near-term valuation standpoint, $2,700 serves as the primary level to monitor, with current market evaluations identifying resistance in the $2,780–$2,800 range. Breaking past $2,800 would clear out this resistance zone, whereas falling under $2,650 could direct focus toward the $2,570–$2,470 region.
Frequently Asked Questions
What is the gas limit being tested on Sepolia?
Ethereum is testing a 200 million gas limit on the Sepolia testnet, which is more than three times its previous 60 million limit.
When does the Glamsterdam upgrade go live on Sepolia?
Glamsterdam is scheduled to activate on Sepolia on October 6 at 13:53:36 UTC, corresponding to epoch 353,024 and slot 11,296,768.
Does the 200 million gas limit apply to the Ethereum mainnet?
No, this gas limit test is strictly limited to the Sepolia testnet. The Ethereum Foundation has not yet announced mainnet activation dates.
What are the key features introduced by the Glamsterdam upgrade?
Glamsterdam introduces enshrined proposer-builder separation (ePBS) and Block-Level Access Lists (BALs) to enhance block production and allow for parallel state reads and transaction validation.
