On January 2, the Ethereum network hosted the Muir Glacier hard fork. The first block was obtained by the Sparkpool pool.
</p>The upgrade was activated onblock #9,200,000, putting aside the so-called «difficulty bomb» for 4 million blocks (approximately 611 days).
Many criticized the decision of the developersto carry out updating on holidays. According to Ethernodes, support for Muir Glacier has not yet been announced by Coinbase, Bitfinex, Poloniex, and some other exchanges. At the time of writing, 14.5% of the nodes have not updated the software to the latest version.
The Ethereum community did not expect that«difficulty bomb» will begin to affect the block generation time so quickly, but the calculations turned out to be erroneous. In order not to delay the Istanbul hard fork to incorporate the corresponding changes, the developers proposed a separate upgrade.
</p>«Difficulty bomb» on the long road to Ethereum 2.0 has been delayed for the third time.
Recall, on December 31, the developers of the Parity client discovered a bug that prevented the correct synchronization of full nodes with the Ethereum network.
