According to Ethereum developers, including Tim Beiko of the Ethereum Foundation, the Gray Glacier hard fork went into operation yesterday without any problems, delaying the difficulty bomb.
In the next few days the Sepolia testnet will also be subjected to the Merge, the penultimate phase before the official merger.
According to Etherscan, Gray Glacier’s hard fork was started on block number 15050000 at 12:54 pm Italian time yesterday. The hard fork will delay the difficulty bomb by approximately 700,000 blocks or 100 days, allowing developers to complete the long-awaited Merge until mid-October.
Ethereum Foundation community manager Tim Beiko promptly highlighted yesterday on Twitter that 20 blocks from the fork, all monitored notes remained synchronized, stating:
“20 blocks after fork, everything seems fine: all monitored nodes except @OpenEthereumOrg, which doesn’t support fork, are in sync. No blocks on the old chain so far!”.
Even Nethermind, developer of the ecosystem, confirmed on Twitter the success of the hard fork, adding that the difficulty bomb was successfully delayed.
The Gray Glacier hard fork was successful
The Nethermind nodes are in place. The block time will drop back to 13 seconds.

The difficulty bomb is a mechanism designed to gradually discourage Ether miners (ETH) from the proof-of-work (PoW) activity on Ethereum, before any Merge between the network and the Beacon Chain based on proof-of-stake (PoS).
This will result in increasing the difficulty level of the puzzles in the PoW mining algorithm, with resulting in longer block times and lower rewards from mining. The mechanism would also make Merge significantly more complicated for developers to complete due to the gradual slowdown in block creation.
It was therefore necessary to postpone the difficulty bomb, as it would have slowed down the creation of new blocks to such an extent that it was almost impossible to introduce new updates to the network.
The difficulty bomb has been postponed on multiple occasions, due to numerous Merge delivery delays in recent years. The previous postponement, Arrow Glacier, occurred in December 2021, postponing the bomb to mid-2022.
Beiko also shared on Twitter a post from the Ethereum Foundation on Thursday, announcing that the Sepolia testnet will hold a Merge dress rehearsal in the coming days, the second of three public testnets to achieve the goal:
“After years of work to bring proof-of-stake to Ethereum, we are now well underway in the final phase: testnet implementations!”.
“With Ropsten already transitioned to proof-of-stake and shadow forks continuing on a regular basis, Sepolia is now ready to merge. After Sepolia, only Goerli / Prater will need to be merged before proceeding to the mainnet.”he added.
Sepolia, the second of the three public test networks, is merging. If you are managing a node on your network, it’s time to switch to an EL / CL combination.
The hashrate has been volatile, so we could hit TTD over the weekend.

On the Ethereum Foundation website, it is vaguely estimated that the official merge will take place in the third / fourth quarter of this year, with the latest post adding that “The date for the Ethereum mainnet proof-of-stake transition has not been set. Any source that claims otherwise is likely a scam. Updates will be posted on this blog.”
