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 |

This is the problem with the bitcoiners. None, none of the folks who commented on thread knew that blockchain and crypto coins are different things. Blockchain is great, crypto currency is bad, very bad. Such ignorant investors.
Quorum is business blockchain. Most business blockchain have no coins. They don't need coins or mining.
BTC was sold by talking about the greatness of blockchain. There are many application that run on blockchains. Some good some very bad. BTC is is VERY BAD application built on the good technology of blockchain. Many ICOs fall into this VERY BAD category.
In other words, blockchain is like the Android or Windows on your phone or device. Bitcoin is a malicious app built on that platform.
Now, folks please get out of hangover of "blockchain s great and so is bitcoin". They are entirely different.
JP Morgan Quorum is perfectly valid for their business case. It has nothing to do with any other silly coins.
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. |

In the near future, many medical blockchains will arise. As we all know that human condition is not steady. When a condition becomes bad, they will seek help to doctors or medical experts. However, some of the case deserves second opinion. Also, there are cases that answers is not at the exact place and exact time. For instance, an individual is diagnosed with a rare disease in Guam, the case is already existing but not on the said country – its in England. They want some second opinion by English medical experts who already mastered that kind of case. Well, obviously the patient doesn’t want to travel 7,500 miles in order to get his medication – so as the doctor.
With medical icos, data can be stored in blockchain and can be pulled out internationally by those medical experts. Not just this, it can save time and medical expenses it can also makes the mode of payment easier through the use of tokens.
Hello Earl, Is Medical icos a blockchain? Bcs I searched the net and couldnt find it. 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 the developer myself.
If you just started to learn about consensus algorithms and decentralized projects itself, chances are high your project will contain massive bugs and will be worthless. If you are really serious about developing a proper project, get a team of a few developer to build proper software. I mean proof of stake yes. I just wanted deepl explanation and how everything is related.
You can take a look at the github repository of ethereum. Proof of stake is pretty detailed explained in the FAQ: https://github.com/ethereum/wiki/wiki/Proof-of-Stake-FAQsEthereum version of Proof of Stake will be like Frankenstein's PoS monster, not really worth your time , unless you wanted bloated confused code running a Bastardization of proof of stake. Study Peercoin design as it is a hybrid of both PoW & PoS created by Sunny King. Then Study Rat4's Blackcoin Proof of Stake only project. Rat4's code is pretty rock solid. 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

The difference between POW and POS mode:
POW：
We are familiar with the working mechanism of bitcoin is POW, namely Proof of work, proof of work mechanism.
Proof of work mechanism (POW) is not difficult to understand, in many cases we are using POW. We just didn't understand it.
Without considering the verification condition. (whether central or non verification center.), We can think of anything with a probability of events accumulated are proof of work, Therefore, POW requires a certain amount of evidence, The proof can be recorded directly can also be based on probabilistic representation, in which the event of small probability cumulative work, The results show that the workload is equivalent to,
POS:
POS is the "Proof of stake," Direct proof that you hold share.In addition to mixed PPC, The real POS money is no mining process, It is in the block stated ownership certificate, after the shares that can be transferred, not mine. In the real world that is common stock equity, is the most simple. The stock is that used to record the equity, also represents the voting rights and the right to return, In a pure POS system, such as NXT, no mining process,
?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? |

Do we not owe it to ourselves to push bitcoin awareness more on social media?
Yes. Agreed. 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.
