[Ethereum Glamsterdam Upgrade to Be Tested on Sepolia Tonight, Block Gas Limit Proposed to Increase to 200 Million] BlockBeats News, October 6: Hours before the Ethereum developers conduct testing of the Glamsterdam upgrade on the Sepolia testnet, they urgently released Prysm version 7.2.1 to address an issue with the block Gas limit settings in the validator client. This ensures that validators can automatically generate blocks with a Gas limit of 200 million as required by the test. Glamsterdam is Ethereum's next major upgrade and will first be tested on the Sepolia testnet. One significant change in this test is the increase of Sepolia's block Gas limit from the previous approximately 60 million to 200 million. Gas is the unit used to measure the computational workload that an Ethereum block can handle. Raising the Gas limit means that a single block can accommodate more transactions and more complex on-chain activities, but it also increases the computational performance requirements for running validator nodes. Prysm is one of the main clients used by Ethereum validators. In its previous version, the configuration for Sepolia did not include the 200 million Gas setting. Therefore, if validators continued running the old version without manually modifying parameters, they would still produce blocks based on the old limit of 60 million Gas. The Prysm 7.2.1 version released on Monday night has the 200 million Gas setting built-in, allowing validators to automatically adopt the new block capacity when Glamsterdam is activated. According to the testing schedule, Glamsterdam will be activated on Sepolia on October 6 at 13:53:36 (UTC). At that time, validators running the latest Prysm version will automatically start proposing blocks with a Gas limit of 200 million. If some validators continue producing blocks based on the old limit of 60 million Gas, it will weaken the evaluation of the network's performance under larger block capacities during this test. The core purpose of this test is to observe whether Ethereum validators can stably process blocks that are three times larger than the previous default capacity. Ethereum has been gradually increasing block capacity and conducting tests to evaluate whether expanding block space will make running validator nodes excessively expensive or impose overly high hardware requirements. If higher block capacities can operate stably, Ethereum will have more block space in the future, accommodating more transactions, stablecoin transfers, and other on-chain applications. This would enhance overall processing capacity before users compete for block space and drive up network fees. It is important to note that the 200 million Gas setting currently applies only to the Sepolia testnet, and Glamsterdam has not yet been activated on the Ethereum mainnet. The results of this test will help developers further determine the appropriate block capacity for the Ethereum mainnet in the future. [Original Link]
