In the Ethereum blockchain, the Muir Glacier hard fork was held to transfer the ” complexity bomb»

On block 9,200,000 in the Ethereum blockchain (January 2 at 11:30 Moscow time), the Muir Glacier update was deployed, delaying the activation of the “complexity bomb” by another 4 million blocks.

According to Ethernodes, as of the morning of the third of January, 99.5% of Ethereum customers synced with the update. Muir Glacier was first proposed by developer Eric Conner in November as part of EIP 2384. The update is intended to delay the activation of the “complexity bomb” for another 4 million blocks – about 611 days.

After this period, the problem may no longer be relevant due to switching to PoS. The final decision to postpone the activation of the “complexity bomb” was made
a month ago, and the update deployment date was set
in late December.

If the Muir Glacier update had not been implemented, the cost of transactions on the Ethereum network could have increased significantly. As fewer blocks are mined each day, the cost of including transactions in blocks increases.

“Imagine we mine a block every 13 seconds – that means we can create about 6,500 blocks a day,” Conner says. “Once we get to the 20-second interval, we will only be able to mine 4,300 blocks a day. If we assume that the network is fully used, the competition will grow day by day. This will lead to higher fees and make transactions more expensive for users of decentralized applications.”

On December 8, the Ethereum network was successfully activated
hard fork Istanbul-this system-wide update was the third for the network in 2019. Earlier last year, The network hosted St hard forks. Petersburg and Constantinople. Istanbul became the eighth hard fork of the network overall. The second part of Istanbul should be the last planned hard fork before switching to Ethereum 2.0, if the developers do not face new obstacles.
