Home » Ethereum Ethereum’s Bellatrix upgrade hiccups jangle nerves… but it’ll be right on the night Reading 2 min Views 7 The Bellatrix upgrade was the last major upgrade before the Ethereum Merge, which will transition the network’s consensus mechanism to proof-of-stake. The Bellatrix upgrade preparing Ethereum for the Merge was successfully completed on Sept. 6 – however concerns were raised over an almost one in ten missed block rate across the last 600 slots. The Bellatrix upgrade updated Ethereum consensus layer clients at epoch 144896 on the Beacon Chain prior to the upcoming Merge scheduled for sometime next week . However, 5% of the validators dropped offline during the hard fork, which contributed to the 9% missed block rate, according to Gnosis co-founder Martin Köppelmann. This led some observers to question the network’s readiness for the big switch to proof of stake. Missed block rate in the last 600 slots: >9%Historically this rate has been around ~0.5%. It shows that Bellatrix caused some issues for some validators. Nothing dramatic but still a number to keep an eye on. — Martin Köppelmann 🇺🇦 (@koeppelmann) September 6, 2022 Köppelmann added that the 9% figure was 1700% higher than the historical missed block rate of 0.5%. The issue may be related to the 25.6% of clients that Ethernodes cites at “not ready” for The Merge. Percentage of Ethereum Clients that are Merge ready. Source: Ethernodes. Partner of Cinneamhain Ventures Adam Cochran said he hoped the “big spike” in missed blocks would get debugged before the Merge proper, adding that “we really don’t want to be seeing unexpected issues at this late stage.” But not everyone is concerned. Anthony Sassano, founder of the Daily Gwei said that having only 5% of validators falling off the network was actually an “an amazing result” and confidently stated “there’s not actually much that can go catastrophically wrong.” with the Merge. So to recap, post-Bellatrix, a few stats: – network participation rate is 94.94%– number of active validators is 403766– number of offline validators 17743– and client diversity for consensus layer clients page will be updated tomorrow so we can check again then — Christine Kim (@christine_dkim) September 6, 2022 The Bellatrix upgrade is one of the last steps prior to the Merge and enables Ethereum consensus layer clients to execute transactions on the Beacon Chain. The Ethereum Merge will transition the network to a proof-of-stake consensus mechanism, which is set to make the network more efficient and secure.
