-- Zennet --
Entirely new software and architectures
Combined with the industry's most solid technologies
Creating a public decentralized Supercomputer
The Zen Protocol presents a novel reward mechanism
While the Blockchain makes it frictionless
We will make it possible to utilize and monetize
all hardware in the world. That's big.


Zennet initiative is a public, distributed, and decentralized Supercomputer. It lives in the world of distributed and decentralized Blockchain applications, and in the huge field of Big Data and High Performance Computing. The latter has captured the most attention and investments in the software market over the last few years, experiencing huge growth. HPC and Big Data are used in countless industries, including medicine, government, and marketing. Big Data alone is at least a $30 billion industry this year.

http://zennet.sc/images/infogr/p1.PNGhttp://zennet.sc/images/infogr/p2.jpg


Zennet is here to power this expansion with everyone's computational resources around the globe. Its most significant impacts on this market are drastically reducing costs and bringing new magnitudes of speed to HPC consumers.

http://zennet.sc/images/infogr/p3.PNGhttp://zennet.sc/images/infogr/p4.PNG

Computation power is traded on Zennet's open market platform. Anyone can rent computation power and use it to run arbitrary tasks. Anyone can monetize their hardware by offering unused computation power for sale.    
Zennet allows Publishers who need computation power to run arbitrary computational tasks. Computation power is supplied by Providers for a negotiated fee. A free-market infrastructure brings Publishers and Providers together. Publishers can hire many computers and run whatever they want on them safely, thanks to cutting-edge virtualization technology. Payment is continuous and frictionless, thanks to Blockchain technology, among other technologies that shall be discussed later on.    

http://zennet.sc/images/infogr/p5.jpghttp://zennet.sc/images/infogr/p6.jpg

The network is 100% distributed and decentralized: there is no central entity of any kind, just like Bitcoin. All software will be open source. Publishers pay Providers directly, there is no middleman. Accordingly, there are no payable commissions, except for regular transaction fees which are paid to ZenCoin miners.       
It is a totally free market: all participants are free to pay or charge any rate they want. There are no restrictions. Hence, we put additional focus on customizability. We allow advanced participants to control all parameters and conditions of their nodes in a versatile way. On the other hand, simplicity and automation are made possible by making the client software implement automatic risk-reward considerations by default. In addition, we present a novel pricing model.       
Following is a sketch summarizing the general idea of the communication protocol between publisher A and provider B:        

Zennet presents new economic aspects, both to the traditional economy and to the world of cryptocurrencies. ZenCoin has a real intrinsic value, as it is fully backed by the right to use a certain amount of computation power. Most of the power-calculating resources are in the hands of the common people, and most of the time they are free.

Many questions may naturally arise. The above description is extremely summarized. Please take some time to read the About Xennet article at http://zennet.sc/ It contains an interesting table presenting Xennet's benefits over Amazon Web Services, the largest computational resources rental firm.

Please stay tuned, share your thoughts and check Xennet Bug Bounty Announcement.

Great question. Please see the detailed table at http://xennet.io which compares Xennet to AWS.

Guessing Windows Server OS won't able to work in this right but maybe in a few years when computers are much more powerful?

It will work on Windows and even on mobiles!
Docker will be executed inside a virtual machine (Virtualbox, QEMU etc.).
The VM will run Xennet-OS that will split containers to each publisher.
Therefore, cross-platform.

Note that since QEMU is a fully user-space hypervisor, it is compatible with any os and architecture able to compile C.

This is by far one of the most interesting projects i saw lately and i will keep my eye out for this one for sure!

I do have a question: What determines the precedence order when several equal entities wish to hire computational resources at the same instance?
If 2 different people for example both offer to pay the exact same price for the exact same resources, put their offer at the exact same time in the system, which one gets the computational power first? (assuming there is a limitation in the available computational power in total and its not enough for both tasks at the same time). How is it decided in a case of a complete tie in demands?
Hope my question makes sense... Smiley

Very good question!

The ultimate theoretical answer is that it's up to the providers and publishers choice. But of course Xennet will be predefined with settings so non-technical users will still be able to rent their computers and get paid, in (probably almost) one click. Yet, the client will be highly customizable. My current plan is to let a JS scripting ability on the client for inputting complex user-defined filters and preferences.

The practical answer for when users do not handle this situation manually and relies on the client's defaults, requires me to highlight several points:

1. As you stated correctly, publishers publish (over the blockchain) a request for providers to connect, including their IP address, and providers connect to them.

2. Some not-very-necessary-for-this-answer background: The publisher do not state a price for a unit of CPU/RAM/etc or time. They state how much they would pay for standard programs, i.e. some common phoronix-test-suite benchmarks. The providers also state their price in terms of canonical benchmarks. Then, the linear-algebra algorithm determines how to decompose those prices into the prices per CPU instruction, RAM fetching etc., and determines the bill at runtime. The algorithm knows how to (optimally!) compensate over the variance between the different kinds of hardware. It's a bit sophisticated and advanced-math mechanism, see our docs for more details. For our case, what needs to be concluded is that not only the publisher's requirements determine a match, but also the performance of each provider, while each having various models of hardware.

3. Each provider will tend to serve several publishers in parallel. If each provider serves 10 publishers, then the risk of both provider and publishers decreases by about x10, since if a publisher do not pay, the provider lost only 10% (note that payments occur every few seconds in a frictionless manner thanks to the Micropayments algorithm, so there will never be a big loss by all means), and if the provider is gone, the publisher loses only the work of 10% of a PC, not 100%. Hence, back to your question, the desired behaviour is to serve both publishers in parallel.

4. Your question still remains if we have many (say 100) publishers with the very same parameters. It is indeed a realistic case: for example, many researchers use Gromacs for molecular dynamics simulation, and they can even work on the same institute with the same terms. So how will Xennet handle this?

5. Same rationale of 3, i.e. reducing risk, points to another risk-decreasing behaviour: say I do have 100 identical publishers. On such case the client will just pick publishers randomly. This is a risk-reducer since it spreads the risks among all nodes.

6. Note that if from that identical publishers, some of them either have richer history than others (seen at the ledger), or, if my specific node served one of them in the past and kept some reputation measurement for this publisher (will be done automatically by the client), it will prefer the one with more reputation.

I hope I addressed your question.
Please (you and everyone) do not hesitate to ask any kind of question about Xennet.


P.S.
"one of the most interesting projects i saw lately" just one? show me another with the same magnitude of redemption Smiley

Thank you for the detailed answer!
It gives a lot of confidence in this project to see that you really gave much thought to all the fine details.
If i have further questions i will definitely ask away.
Oh, and I stand corrected - this is the most interesting project i have seen lately! it's a keeper!  Wink
Will surely keep an eye out for more info on development and hope to participate in your scheduled pre-sale!
