Ethereum Merge Delayed as “Difficulty Bomb” Pushed Back Again

The Ethereum core development team had a meeting last Friday that delayed the “difficulty bomb,” a key catalyst in “the Merge,” by another two months.

Barriers to the Merge

After discussing some bugs arising from the testnet, the Ethereum core developers proposed EIP-5133 to delay the “difficulty bomb” to mid-September. 

This is the 6th time in its development history (starting in 2017) that Ethereum has delayed the activation of the difficulty bomb, which would interfere with the Merge.

“In short, we agreed to the bomb delay. We were already over time, and want to be sure that we sanity check all the numbers before selecting an exact delay and deployment time, but we are aiming for a ~2 month delay, and for the upgrade to go live late June,” Ethereum Core Developer Tim Beiko confirmed on Twitter.


The “Difficulty Bomb” is a mechanism that increases the difficulty of mining ETH over time. Once this bomb is activated, it will make the Ethereum network extremely difficult to mine, forcing miners to switch to the Proof-of-Stake (PoS) transaction validation mechanism.

What is Ethereum:

Ethereum is an open-source, distributed computing platform based on blockchain technology that can execute smart contracts – that is, the terms written in the contract will be executed transparently, automatically when the previous conditions are satisfied, and no one can interfere. At the same time, Ethereum also allows developers to build decentralized applications (DApps) and decentralized autonomous organizations (DAO).
