- Ethereum is set to activate Glamsterdam on Sepolia today with a 200M gas-limit test.
- Glamsterdam introduces enshrined proposer-builder separation and block-level access lists to improve Ethereum’s block production and validation.
Ethereum is getting ready to test a 200 million gas limit on the Sepolia testnet as the Glamsterdam upgrade progresses to its next testing phase today. This update stems from Prysm v7.2.1, a release published by Offchain Labs on October 5 that introduces the Sepolia gas-limit schedule and establishes 200 million as the default gas limit for validators following the Gloas fork.
Additionally, the new Prysm update modifies data column management by enabling partial data columns by default. With this modification, nodes can gossip individual cells rather than full data columns. Prysm additionally incorporates configuration settings for Gloas builders, encompassing builder URLs, minimum bids, and builder bid timeouts.
The 200 million gas configuration is more than triple Sepolia’s prior limit of 60 million gas. According to Prysm’s latest release notes, this new schedule goes live at epoch 353,024, aligning with the Sepolia configuration specified for the Gloas fork. Validators running Prysm v7.2.1 are not required to manually configure the 200 million limit, though operators retain the option to specify an alternative limit via proposer configurations or the keymanager API.
Glamsterdam Reaches Sepolia Today
The Ethereum Glamsterdam upgrade is slated to go live on Sepolia today at 13:53:36 UTC on October 6, coinciding with epoch 353,024 and slot 11,296,768. This upgrade merges the Amsterdam execution-layer updates alongside the Gloas consensus-layer updates.
Key features of the upgrade include enshrined proposer-builder separation (ePBS) and Block-Level Access Lists (BALs). BALs are built to track the accounts and storage slots touched within a block, enabling clients to execute a higher volume of state reads and transaction validation processes in parallel. Furthermore, Glamsterdam alters gas accounting for state creation, state access, calldata, and access lists.
This 200 million gas evaluation applies solely to Sepolia and does not establish a new gas limit for the Ethereum mainnet. The Ethereum Foundation has not yet disclosed activation timelines for Hoodi or the mainnet.
At the same time, ETH trades near $2,714 per CoinMarketCap data, boasting a market capitalization of roughly $331 billion alongside a 24-hour trading volume exceeding $10.2 billion. Over the past 24 hours, ETH has slipped about 0.8%.
Historical market data shows that ETH finished at $2,710.42 on October 5, following a peak September high of $2,785 reached on September 23.
From a near-term trading outlook, $2,700 serves as the primary level to monitor, whereas current market evaluations position resistance near the $2,780–$2,800 range. A breakthrough past $2,800 would clear out the current resistance zone, whereas a decline beneath $2,650 could direct attention toward the $2,570–$2,470 band.
Frequently Asked Questions
