Ethereum has gotten really expensive to use (fees) and really slow (transactions take a long
time or fail (and then you still paid the network fees).
Stolen from the pinned comment: “Due to some recent changes and upgrades on the Ethereum
network, the cost to run the HEX smart contract code is increasing to a point where it negatively
impacts the HEX ecosystem. Rather than sit by and watch this happen, Richard Heart has
opted to take matters into his own hands and create an improved version of the Ethereum
network, which will be faster and cheaper than the original Ethereum network.
By doing this, the PulseChain network will be Ethereum compatible and will be able to make use
of many of the existing tools and infrastructure developed for the Ethereum network.”
