Hi to all,
A Blockchain is a public (or at least shared) digital notary.
The easiest (hence probably the more meaningful) use case is to disrupt
existing notary systems (disrupt in its accurate definition: deliver
something that is initially less powerful, but evolves greatly faster).

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

In the Netherlands we have a national system called the LSP, which makes
medical data available to other clinicians.
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 "CT

Bitcoin is since a few weeks prohibited in China but it seems hard to kill.
But still, I don't think the use of blockchain in

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

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.

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

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

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

One problem with blockchain is that people think every blockchain is secure,
anonymous and decentralized – but that really depends on the specific
implementation.
You can probably still create a proof of something-that-is-not-work-or-space
that is reasonably decentralized, given you have enough
In other words:
What is BlockChain solving?
My answer: it solves non-repuduation without a third trusted party.
Correct?
