You can probably still create a proof of something-that-is-not-work-or-space

bitcoin doesn't use a reduced proof of work. That's the costly feature of
it, and why it's genuinely distributed.

Can you explain why?
Bitcoin, f.e. is about billions of dollars without central authority,
that is one of the reasons the Chinese government prohibited the

As for that, Namche had faster internet than myself at home, last time I
checked.

In the healthcare related blockchain ideas or prototype implementations I have
heard about so far something different than proof of work is used, for example
proof of authority. That has other drawbacks and challenges, but it does not
suffer from the same power consumption problems.
Also any

I am not really into that technical knowledge like radio-modulation or
laser-light modulation. But when they communicate with the Hubble

Bitcoin is since a few weeks prohibited in China but it seems hard to kill.

It must be clear that Blockchain is not a complete solution and should be
seen as a piece within the gear.
Who we have approached blockchain, we see it as an opportunity for
innovation, which needs "some surgery" to be used in the health area, and
that its current implementation is not to make

I think we are heading an era where it can be impossible to tell where
from and/or when data are received /created and which event created the
data or made the data cause to interchange when the data do not tell us
themselves on an accountable way. For that we need an open notary-system
