Holochain itself is not a platform. It is a pattern. Like HTML. We are giving it away to the world for free. It is open source. It does not require web servers. Or miners. Or cryptocurrency. Every user of a particular app, runs that app, showing up as both user and host. Holo is making use of this holochain pattern and is reaping the efficiency and resilience benefits that result.
really you say they are not blockchain, more precisely the framework in Dapps, if the equals PHP thing is not HTML you mention it is Yii Framework and the other so this is very useful for the development of Dapps in the future
