Bitcoin cash now has 32 MB blocks and smart contracts.
The controversial hard fork of bitcoin hard forked again several days ago in an effort to add new functionality to the cryptocurrency protocol and further differentiate it from its predecessor. But in the process – executing at block 530350 – a portion of the bitcoin cash community was left behind.
At the time of writing, between 16 percent and 17 percent of bitcoin cash nodes are running old software and because of the way upgrading by hard fork works (whereby changes are not backwards compatible), those nodes are now running on a completely separate network. As such, if any user running one of those nodes were to make a transaction, the new, larger bitcoin cash network would not recognize it.
Critics of bitcoin cash argue it’s a bad sign that so many nodes haven’t upgraded, since those users are now completely cut off from the rest of the network.
