I just wanted to know how the end users are going to get tested for cancer?
Are you guys going to provide some kits that will be delivered to the users' homes or do they have to come to a designated lab to get tested?

Hello!

I would like to try a project for a research that I am doing.

I want to try to connect two different blockchains.
One built on top of Etherium and the other on top of Hyperledger Fabric.
I want to build a system by which these two separate Blockchains can exchange data between each other while remaining isolated entities.

Can anyone give me some suggestions on how I can achieve something like this?

Thanks.

Can you please elaborate on what you mean by "cross-chain"?
Thanks

Yes. Bitcoin and blockchain isn't the samething. Bitcoin is a cryptocurrency built on top of blockchain technology.
Although we are seeing blockchain technology being mainly used for Cryptocurrencies now (which I am not saying is a bad thing), you can actually make a lot of different kinds of applications on top of them.
 
However I think enterprises wanting to make applications on top of blockchain technology would really not want to make it on top of public blockchains like Etherium.
That is where private blockchains like Hyperledger fabric and Quorum are coming in.

For instance, companies who might be wanting to use blockchain apps to help then on their research on genetic engineering or sth would probably make an app on top of private networks like Hyperledger fabric or Quorum. In cases like these there are no need for cryptocurrencies.

Personally I feel the markets for Bitcoin and Quorum are quite different.

I think he is suggesting if ICOs like these will exist in the future, or it might be he wants them to exist in the future.
But A new blockchain - (separate from etherium) built for the sole purpose of healthcare would be nice.

If things like this actually were to exist, it would be pretty awesome. But, are there any ICOs trying to do sth similar to this?

I am really confused about how the shift will occur from PoW to PoS for Etherium.
How will it effect Miners and how will it effect people who have ether?
I am also concerned about the integrity of the entire thing.

Can someone please tell me what are the advantages of x13 over x11
and if there are any security issues with x13?
Thanks in advanced

?Probably a dumb question, but is PoS less secure (as in more prone to being successfully attacked) than PoW? How is PoS providing security in the network?

Yes, but the question is how is one supposed to do that? I mean what strategy should we follow when trying to raise awareness on social media?

I shall try to explain as simply as I can and as much as I understand. I am not an expert but I shall try.

Nodes (Miners) solve bitcoin puzzles by guessing at random. The hash function makesoutput prediction impossible. So, miners guess the mystery number and apply the hash function to the combination of that guessed number and the data in the block. The resulting hash has to begin with a pre-established number of zeroes. There's no way of knowing which number will work, because two consecutive integers will give wildly varying results. What's more, there may be several nodes that produce the desired result, or there may be none (in which case the miners keep trying, but with a different block configuration).

The first miner to get a resulting hash within the desired range announces its victory to the rest of the network. All the other miners immediately stop work on that block and start trying to figure out the solution for the next one. The victorious miner gets some new bitcoin as a reward for its work.

The difficulty of the calculation (the required number of zeroes at the beginning of the hash string) is adjusted frequently, so that it takes on average about 10 as per decided by the bitcoin devs.
