On January 2, the Ethereum network hosted the Muir Glacier hard fork. The first block was obtained by the Sparkpool pool.</p>
Upgrade activated on block # 9,200,000, postponing the so-called “complexity 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 the “bombcomplexity ”will begin to affect the time of generating blocks so quickly, but the calculations turned out to be erroneous. In order not to delay the Istanbul hard fork to include the appropriate changes, the developers proposed a separate upgrade.</p>
The "bomb of complexity" on the long journey to Ethereum 2.0 is postponed 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.
