Say hello to Hole\u0161ky, a new Ethereum testnet that successfully went live today after a configuration problem prevented the network from launching<\/a> two weeks ago on the 1-year anniversary of the Merge<\/a>.<\/p>\n Hole\u0161ky is intended to replace Ethereum\u2019s Goerli testnet \u2014 Ethereum\u2019s validator and staking-focused testnet \u2014 which will be retired in 2024.<\/p>\n A minor bug reported on today\u2019s<\/a> all-core-developers call, affecting some Prysm Ethereum clients, was not enough to derail the launch, according to Barnabas Busa, a software engineer at the Ethereum Foundation. Validator participation has been climbing in the hours since, Busa said, expected to reach 90% by Friday.<\/p>\n Goerli is still expected to be used for the Dencun upgrade<\/a>, featuring EIP-4844<\/a>, on its way to mainnet release.\u00a0<\/p>\n But before that step, the upgrade has been running a gauntlet of developer networks \u2014 or devnets.<\/p>\n Core developers discussed the imminent launch of Devnet-9, which will debut \u201cFriday or early next week\u201d according to project coordinator Tim Beiko. That\u2019s slightly delayed from the planned Sept. 27 start date projected on the previous developer call.<\/p>\n The Dencun upgrade initially aimed for a hard fork date in the fourth quarter of this year. However, due to the slower-than-expected progress of the Devnets, a 2023 hard fork now seems unlikely.<\/p>\n Busa told his colleagues on the call, \u201cwe probably need a Devnet 10 too,\u201d though it\u2019s expected to be \u201ca shorter-lived Devnet.\u201d<\/p>\n The new goal is for the first testnet launch to occur prior to November\u2019s Devconnect conference, taking place in Istanbul in mid-November.<\/p>\n If all goes smoothly, the mainnet could follow as early as January 2024.<\/p>\n Don\u2019t miss the next big story \u2013 join our\u00a0free daily newsletter<\/a>.<\/strong><\/p>\n
