Ethereum Developers Encounter Minor Bugs, But Upgrades Remain on Schedule

According to reports, Tim Beiko, the core developer of Ethereum, tweeted that Marius Van Der Wijden, the developer, found a public test network Shapellabug, which occurred during the full synchronization of empty blocks (no transactions or withdrawals). Several other clients also encountered this problem. However, this problem is easy to test and can be quickly repaired. The team believes that this will not affect the schedule of Sepolia upgrade, which is still planned to be carried out at 12:00 on February 28. In addition, Barnabas Busa updated the latest withdrawal Devnet for the stress test of Shapella. The Devnet has 600000 verifiers, of which 360000 verifiers perform the withdrawal voucher update at the time of bifurcation. The client sees a surge in RAM+CPU usage. The deops team will monitor the development network in the next few days to see how many credential update messages are included and lost. The test also revealed the problem of PrysmBesu, where Besu limited the number of responses it sent through RPC to prevent DoS, but the number of responses Prysm expected was higher than Besu’s current limit. Besu team is currently investigating this matter. In addition, developers also plan to conduct another main network shadow bifurcation, and will do some Mev-Boost tests on it. On February 10, the Ethereum Foundation said that the upgrade of Shanghai+Capella (Shapella) main network was entering the final pre-release sequence – the public test network. Shapella includes many functions, but the most important thing for the pledgor and the consensus layer is to support withdrawal. Withdrawing verifiers can withdraw in full, while active verifiers with a balance of more than 32ETH can withdraw in part. In addition, Sepolia, the first long-term public test network, is scheduled to be upgraded on February 28.

Analysis based on this information:


According to recent reports, Ethereum developers have encountered minor bugs while conducting tests on the Shapella public test network. Tim Beiko, the core developer of Ethereum, tweeted that Marius Van Der Wijden discovered the Shapellabug during the full synchronization of empty blocks, which impacted several other clients. Fortunately, this bug is easy to test and repair, and the team believes that it will not affect the planned upgrade to Sepolia on February 28.

However, during the stress tests of Shapella, Barnabas Busa revealed that there was an unexpected surge in RAM+CPU usage, and the Besu team is currently investigating the issue. The team plans to monitor the development network over the next few days to see how many credentials are lost.

Developers also plan to conduct another main network shadow bifurcation, which will undergo some Mev-Boost tests. The Ethereum Foundation confirmed that the upgrade of Shanghai+Capella (Shapella) main network is entering the final pre-release sequence, and the public test network is an essential aspect of the upgrade process. With the main components of Shapella including withdrawal, supports for pledgor and consensus layer, users can withdraw verifiers both in full and in parts, depending on their balance.

In conclusion, although minor bugs have been encountered during the testing process, Ethereum developers remain optimistic about the upcoming upgrades. The Shapella public test network has been successful, and the team is devoted to ensuring a smooth transition to Sepolia on February 28. The team’s constant monitoring of the network sends a positive signal of their dedication, and Ethereum users can expect further innovations with future upgrades.

Overall, the message suggests that Ethereum is moving forward with its planned upgrades, despite minor bugs encountered during pre-release testing. The team remains optimistic and committed to ensuring a smooth transition to Sepolia, and users can expect more innovations in the future. The keywords, Ethereum, Shapella, Sepolia, Devnet, and upgrades, emphasize the main points of the message and highlight the importance of the public test network.
