Ethereum developer Hudson Jameson has published information about the upcoming Muir Glacier Ethereum hard fork, scheduled for January 2, 2020 at block 9,200,000.
The developer clarified that the launch date may change, depending on the mining speed and time zones. In addition, node operators and miners are advised to update the SOFTWARE before December 30, and information about the approximate launch dates can be tracked on the Etherscan website.
Users who store ETH on cryptocurrency exchanges, as well as on hardware, mobile, and web wallets, will not be required to take any action, otherwise they will be issued with appropriate instructions.
The Muir Glacier hard fork is designed to delay the activation of the “complexity bomb” by another 4 million blocks (for a period of about 611 days). It is likely that after this period, the problem will become irrelevant due to the transition to PoS, although this is not the first time such a postponement of the activation of the “bomb” has been carried out. Previously, the issue of changing or removing the “complexity bomb” was discussed, but given the short time frame, the developers decided to use the proven method of delaying activation.
Last week, Ethereum developer Danny Ryan (Danny Ryan) announced a security audit of Ethereum 2.0 at the zero phase stage, which is scheduled to take place in February. As part of this audit, the system will be checked for vulnerability to DoS attacks, as well as for misuse of resources, which may create unwanted chains.
Recall that in October, Vitalik Buterin spoke about plans to launch Ethereum 2.0 and what to expect from this historic update.
