Ethereum’s Arrow Glacier network upgrade delays the network’s difficulty bomb until June 2022. Many previous updates have also extended the deadline for the difficulty bomb. The difficulty bomb will, by design, make mining on Ethereum uneconomical and difficult to do. This feature motivates the development of Ethereum 2.0 and will force miners to change over to the new Proof of Stake blockchain.
The update contains one Etherereum Improvement Proposal (EIP) delaying the difficulty bomb. An EIP is a proposed change created and reviewed by the Ethereum community. Arrow Glacier is particularly exciting as it looks to be the last extension of the difficulty bomb before Ethereum 2.0’s release.
