The Ethereum Foundation website has published details of another hard fork designed to delay the activation of the so-called complexity bomb.
The update was called Muir Glacier and will be activated on block # 9200000, which is expected to be produced on January 2, 2020, depending on the speed of release of the blocks.
In a message, the lead developer of the Ethereum Foundation, Hudson Jameson, asked node holders to update their software by December 30, 2019.
The complexity bomb is a complementary Proof-of-Work algorithm for regulating the complexity of Ethereum mining, exponentially increasing its value every 100,000 blocks. By increasing the time spent in blocks, the complexity bomb is also designed to encourage participants in the Ethereum ecosystem to switch to the Proof-of-Stake (PoS) algorithm.
Earlier, Ethereum developers discussed the possibility of completely removing this mechanism, but in the end they agreed to postpone it, for which Muir Glacier hard fork will be held. After it, the activation of the complexity bomb will be delayed by 4 million blocks.
According to Etherscan, today the difficulty value is 17.15 seconds. This, although almost twice as low as in September 2017, still leads to too long a transaction processing time.
