Core Ethereum developer details changes to expect after the Merge

Tim Beiko, Core Ethereum (ETH), developer has provided a list of suggestions and expectations regarding the upcoming Merge. This is for applicatio developers and protocol developers on Ethereum.

Beiko suggested that users of protocols and apps should test things to make sure nothing breaks. On May 24, he tweeted “Run stuff. If something is unclear, or broken, please leave a comment.”

Yes! You can run stuff. If something isn’t clear or broken, please leave a comment. They are also extremely useful!

Beiko encouraged developers and users to pay attention and be ready for the Merge.

The Merge is the long-awaited and complex moment in which the Ethereum network moves from Proof-of-Work to Proof-of-Stake consensus. It will then be called “Consensus Layer”, and it is expected to take place in August of this year.

Testnets were used to ensure that there weren’t cross-client issues and that the Merge doesn’t cause any application failures. In a separate Twitter thread, Beiko noted that such problems are unlikely to occur because “99%” of changes affect protocol layers while “nearly none are made to the application layer.”

Here are some thoughts about #TestingTheMerge Protocol layer testing != application level testing. The protocols are tested by client + protocol teams. They focus on protocol changes that do not cause cross-client problems or break existing applications.

Beiko said that developers need to be aware of two major changes in smart contracts and the Merge. He reminded developers that the beacon randomness method, which is used to run applications, would be changing. This is necessary to switch to PoS and was published in an Ethereum Foundation update (EF) last November.

Block times will decrease from 13 seconds per block down to 12. This will result in smart contracts that use block production speed to measure time running one second faster after the Merge.

Beiko seemed to be confident that, despite delays in the execution of the Merge the potential problems have been consolidated into one echelon.

“Outside of cross-client testing, these two edge cases and the greatest risk of disruption, “tooling” and “infrapipes” are the most dangerous.

He said that if there were any issues during the extensive testing and shadow forks, the Merge would be delayed further to ensure security.

“If we discover issues at any point, we’ll take the time to fix them + address them before we move on. Only then can we consider moving mainnet to proof-of-stake.

ETH investors are not worried about their coins being stolen and dumped at the Merge. Korpi, a DeFi educator, posted on Twitter on May 23 that the ETH staked at the Beacon Chain cannot be unlocked until a later upgrade to network after the Merge. This includes the rewards you earn from staking.

He stated that coins will be unlocked once they are released.

The Beacon Chain currently has 12.6 million ETH. The Beacon Chain, which was launched in December 2020, was one of the first steps towards making Ethereum a PoS network.
