High Performance Blockchain HPB: Mainnet Upgrade (First Phase)
HPB team will start the HPB MainNet upgrade today to optimize the MainNet performance and implement some key technical breakthroughs.
In order to better support the hardware wallet, optimize the chainid and make sure the process is performed smoothly, the upgrade will be divided into two phases: the first phase will be completed at the block height of 2560000 (expected to be May 17, 2019 China Standard Time); the second phase is expected to be completed on June 10, 2019 China Standard Time. The exchanges will also complete their upgrade of our MainNet by that time. During the upgrade, transfer and withdrawal of HPB will be suspended due to technical adjustments of the exchanges (for more details, please refer to the announcement of the exchanges).
The cryptocurrency mainnet operates according to certain rules. To improve network performance or correct errors, it is periodically made changes. A hard fork is changes that are not compatible with previous versions of programs that support the cryptocurrency network and in order to continue to mine cryptocurrency, miners need to update the software.
In some situations, as a result of a hard fork, a completely new cryptocurrency may appear, as happened with Bitcoin Cash.
