The implementation of Gray Glacier on the Ethereum network delayed the bomb difficulty until November, a temporary target for moving to PoS. Ethereum (ETH) developers have completed a planned upgrade of the Gray Glacier network and successfully dropped the network difficulty bomb. From the looks of it, the Ethereum Gray Glacier hard fork has added another 100 days to the protocol difficulty bomb through September. Following the success of the hard fork, the Sepolia Ethereum testnet is preparing to undergo its merge tests over the next few days.
Ethereum from Gray Glacier
The Gray Glacier hard fork occurred on Thursday, June 30 at block elevation of 15.05 million. The network update implements Ethereum Improvement Proposal (EIP) 5133 and aims solely to change the parameters of the Ethereum difficulty bomb. Prior to its successful implementation, the Gray Glacier hard fork required client software providers such as Geth and Nethermind to update their Ethereum nodes. In June, the Ethereum Foundation referenced this update in a blog post announcing the upgrade of Gray Glacier.
Ethereum Trouble Bombing
The Ethereum Troubled Bomb is an integral part of the leading smart contract platform. This is the piece of code that exponentially increases the difficulty required to mine Ether (ETH). In addition, this code also ensures smooth execution of the network transition from proof-of-work to proof-of-stake consensus.
The difficulty bomb mechanism makes merge transitions significantly more difficult for developers to implement. This is because block generation is gradually slowing down.
Bomb Trouble was originally scheduled to be operational on June 29, pending completion of the merger. However, due to delays in the proposed merger, the need for a difficulty bomb in June has become obsolete. However, this is not the first time Ethereum mergers have been delayed.
The Network Trouble Bombing has seen several adjustments over the last few years to compensate for the many merge delays. The hard bomb has been delayed on five different Ethereum upgrades so far. Upgrades include Byzantium, Constantinople, Muir Glacier, London and the most recent Arrow Glacier upgrade last December. Arrow Glacier’s increasing difficulty bomb has been pushed back from December 2021 to the middle of this year.
Sepolia Ethereum Merger
Ethereum Foundation Community Manager Tim Beiko discusses the Seplia merger. According to him, the trial network will conduct a detailed and extensive merger rehearsal in the next few days.
