The cryptoasset (virtual currency) community plans to implement a major upgrade of Ethereum on the 15th, which could temporarily disable many features related to Ethereum in the hours before and after the upgrade. The upgrade will change the way transaction orders are processed and reduce power consumption by about 99%. It is assumed that virtual currency users will not be affected by the upgrade, but they should be aware of bugs and other glitches as well as scams after the update.
