PANews reported on September 19 that the research company Rated posted on the The percentage of blocks is double the average over the past 30 days. This impact can be traced back to the Geth version, which introduced block production issues that were exacerbated by the way Prysm handles block production logic (prioritizing local blocks over boosted blocks). Given that GETH and Prysm are the most popular EL and CL clients respectively, the combined impact is a 2 sigma decrease in network-wide effectiveness. However, in the approximately 3 years that the Beacon Chain has been running, the 2 sigma drop in effectiveness has not really had an impact on the overall good functioning of Ethereum. In addition, Ethereum community developer terence.eth said on the The chain is still running smoothly. While Geth's bug interfered with block production, Prysm prioritizes security, it checks local blocks first and if that fails, it stops block production even if a builder block is specified. We're lucky : 1. Prysm is not a super dominant client. 2. Not all upgraded to Geth v1.13.0 at the same time. 3. The Geth team responded and fixed quickly." According to yesterday’s news, the Ethereum client Geth released a hotfix version v1.13.1 to fix issues such as invalid block generation.
