Ethereum developer Tim Beiko recently update on Twitter that the ETH POS merger “will be a more complicated upgrade than the previous ones.” Therefore, he added that they will need an “extra buffer over their regular upgrade schedules” as they pushed the EIP-4345 upgrade. He added,
“A lot of the work will be spent planning for ‘disaster recovery’ cases, which is quite difficult to estimate. “
He further explained that developers will likely update their nodes more than once, as they will use the proof of work difficulty to define the merge. He added,
“The difficulty bomb is based on the current hashrate of the network, and if the hashrate drops rapidly before the merger (because miners want to sell their GPUs), it could accelerate the advent of the bomb.”
With this event in mind, the date of the EIP-4345 difficulty bomb has been pushed back. It was supposed to die out in December, but it will now be postponed to June 2022. In this context, Beiko explained,
“We need all client teams to be ready for the merger and different teams can be comfortable with different deadlines. “
Beiko warned that pushing the bomb twice can “disrupt the progress of the fusion” and programming it “too far” can cause it to lose its “force function utility.” But, he added,
“We would like this to be the last time we fend off the bomb, but everyone agrees that a safe and well-tested fusion is by far the most important thing, and we agree to fend off the bomb. bomb twice if necessary. “
Essentially, Ethereum’s improvement proposal stated that it aimed for the merger to happen before June 2022. However, if the merger is not ready by then, EIP-4345 may be delayed further by the appearance of things. On the contrary, Beiko said there are a lot of “unknowns” and there is also a possibility that the Ethereum bomb upgrade is brewing as well.
Therefore, Beiko thought that four months was a “generous time frame” to run the codes before the mainnet merger.
Apart from that, the developers at ETH recently released Amphora, another crucial upgrade to the merger. The various stages of the upgrade included milestones M1, M2, M3, and M4 which focused on implementing fusion specifications such as increasing technical complexity and node diversity. Apart from this, Beiko also informed that Pithos, the new devnet, has also been successfully launched.
Beiko cited another developer and said having a clear set of milestones has contributed to successful upgrades so far. And, they plan to keep that approach as the channel heads to The Merge.
