Ethereum Completes Muir Glacier Hard Fork But Leaves One Client Behind
The Ethereum network has just completed its Muir Glacier hard fork, with the sole improvement proposal being to delay the difficulty bomb for another 4,000,000 blocks.
In fact, the latest hard fork only became necessary following the Istanbul upgrade, due to a realization that estimates predicting the timing of Ethereum's difficulty bomb for mid-2020 were wrong.
The difficulty bomb is a mechanism to gradually increase the difficulty of new block creation and is a step on the roadmap to Ethereum switching to a proof-of-stake consensus algorithm.
Discounting nethermind's synching issues, it is estimated that around 80% of the total active nodes on the network are Muir Glacier-ready.
The Muir Glacier hard fork comes less than a month after the previous Istanbul upgrade on Dec. 7.
