The problem bomb-delaying Grey Glacier arduous fork went reside on Ethereum on Thursday and not using a hitch, based on the community’s core devs together with Ethereum Basis’s Tim Beiko.
The Sepolia testnet can also be set to run by its Merge trial over the following few days and is the second final testnet to undergo the trial earlier than the official Merge.
In accordance with Etherscan, the Grey Glacier arduous fork was initiated on block quantity 15050000 at roughly 6:54 am EST on Thursday. The arduous fork will now delay the problem bomb by roughly 700,000 blocks or 100 days, giving devs till mid-October to finish the long-awaited Merge.
Ethereum Basis neighborhood supervisor Tim Beiko promptly went to notice on Twitter in a while Thursday that at 20 blocks previous the fork, all monitored notes remained in sync, stating:
“20 blocks previous the fork and it is wanting good: all monitored nodes besides @OpenEthereumOrg, which doesn’t help the fork, are in sync. No blocks on the previous chain thus far!”
Ethereum ecosystem developer Nethermind on Twitter additionally confirmed the success of the arduous fork, including that the problem bomb had been efficiently delayed.
Grey Glacier arduous fork is profitable
Nethermind nodes are positive. Block time will return all the way down to 13 seconds.

The problem bomb is a mechanism put in place to progressively disincentivize Ether (ETH) miners from proof-of-work (PoW) mining on Ethereum forward of the community’s eventual merge with the proof-of-stake (PoS)-based Beacon Chain.
That is performed by growing the problem degree of puzzles within the PoW mining algorithm, thus leading to longer block occasions and fewer ETH mining rewards. The mechanism would additionally make the Merge considerably extra sophisticated for devs to finish as a result of its gradual slowing of block-creation.
Pushing again the problem bomb was required, as it could have slowed down new block creation a lot that it could nearly be unimaginable to introduce new community upgrades.
The problem bomb has been pushed again on a number of events as a result of Merge experiencing quite a few delays over latest years. The earlier Arrow Glacier delay occurred in December 2021 and pushed the bomb again till the center of 2022.

Sepolia Merge
Beiko additionally shared a publish on Twitter from the Ethereum Basis on Thursday saying that the Sepolia testnet will do a costume rehearsal of the Merge over the following few days, marking the second of three public testnets to take action:
“After years of labor to deliver proof-of-stake to Ethereum, we at the moment are effectively into the ultimate testing stage: testnet deployments!”
“With Ropsten already transitioned to proof-of-stake and shadow forks persevering with commonly, Sepolia is now prepared for the Merge. After Sepolia, solely Goerli/Prater will have to be merged earlier than shifting to mainnet,” the publish added.
Sepolia, the second of three public testnets, is merging In the event you run a node on the community, now could be the time to improve to an EL/CL combo

On the Ethereum Basis web site, it vaguely estimates that the official Merge will undergo throughout Q3/This autumn this yr, and the newest publish additionally provides that “the date for the Ethereum mainnet proof-of-stake transition has not been set. Any supply claiming in any other case is more likely to be a rip-off. Updates shall be posted on this weblog.”
