Throughout a call on Thursday, Ethereum (ETH) builders talked about potential dates for the Merge – the huge and much-anticipated occasion when Ethereum strikes from the proof-of-work (PoW) consensus mechanism to proof-of-stake (PoS).
The dates talked about within the doc shared through the name embody September 15, 16, and 20.
Notably, an improve that can begin the complete Merge course of must occur first. This improve is known as Bellatrix, and about two weeks have to go between it and the precise Merge.
There was additionally a dialogue about dashing up the hashrate in order that the time between Bellatrix and the Merge can be shortened from 14 to 7 days, or a 10-days “compromise”.
There additionally must be a adequate period of time earlier than the Merge in case one thing with Bellatrix goes unsuitable, they stated.
All this stated, most builders appear to be in favor of seeing Bellatrix on September 6, which signifies that the Merge could comply with on the twentieth (or earlier). One other risk is to have Bellatrix on the primary day of September, then the Merge on the fifteenth.
The primary situation goes together with earlier estimates. In mid-July, developer Tim Beiko proposed September 19 because the tentative date.
Throughout this most up-to-date name, the builders additionally stated that they wish to keep away from having the Merge on a weekend, and a few stated to keep away from Friday for the Merge so to not hit the weekend.
There can be one other name subsequent week when the builders will focus on the tentative dates once more. Importantly, there isn’t any actual date for the Merge but.
In the meantime, the builders additionally mentioned the Goerli testnet Merge that occurred on Thursday. Although some points had been famous, together with a bug in one of many purchasers for which they are saying there’s a repair, the individuals within the name agreed that this merge was profitable. The testnet merge noticed the Goerli testnet merge with the Prater testnet, a PoS beacon chain, and represents the ultimate check earlier than the precise Merge takes place.
The 2 earlier testnet merges, Ropsten and Sepolia, had been thought-about profitable as properly.
At 8:00 UTC on Friday, ETH was buying and selling at USD 1,890, unchanged in a day and up 17% in every week.
Following the decision, Ethereum co-founder Vitalik Buterin tweeted that,
“The terminal whole issue [TTD] has been set to 58750000000000000000000. This implies the ethereum PoW community now has a (roughly) mounted variety of hashes left to mine.”
Buterin additionally shared a TTD prediction for the Merge, by border.wtf, which (on the time of writing) acknowledged that “round 872.3 TH/s within the community is required as of now” – and that the set TTD is anticipated round September 15.

This TTD has additionally been confirmed in a weblog submit by Danny Ryan, Core Researcher and ETH 2.0 Coordinator on the Ethereum Basis. Ryan, nevertheless, famous that this TTD is “tentative” and that,
“The TTD relies on Proof-of-Work issue and is thus a bit laborious to estimate exactly. The goal date is September 15, 2022, however this estimate may need even every week of error.”
Subsequent week, all estimates can be re-checked through the builders’ name, and “the TTD will both be confirmed or a closing adjustment can be made to higher hit the goal date.”
Ryan additional defined that the Merge itself consists of a sequence of two upgrades: the aforementioned Bellatrix on the Consensus Layer, and Paris on the Execution Layer.
Bellatrix upgrades the Beacon Chain to be “Merge conscious”, and it’s activated on the chosen epoch (144896).
He added,
“Paris is the Merge transition itself, by which Ethereum Mainnet hot-swaps its consensus from Proof-of-Work to the Beacon Chain’s Proof-of-Stake. The Paris improve prompts on the chosen Terminal Whole Issue (TTD).”
