Trusted & Secure Crypto Project

PerFix is a technology that seeks to combine the latest advances in digital finance, decentralized applications and artificial intelligence.
The security of your transactions is ensured by the time-tested CryptoNote protocol. The hybrid POW and POS consensus algorithm makes it possible for anyone to mine and use PerFix.

How to start?

Choose your wallet
To start using PerFix, first of all, you will need a wallet. Visit our downloads page and choose the wallet that suits you.
There are PerFix wallets for different platforms that provide everything you need so that you can start using PerFix right now.

Get some coins
After the wallet is installed, you will need to put some coins into it.
You can use mining to get PerFix coins or buy PFX on a cryptocurrency exchange.

PerFix principles

Safety
Users must be able to trust PerFix for the security of their transactions, without the risk of errors or attacks on the network. All transactions are cryptographically secured using
the latest and most efficient encryption tools.

Privacy
PerFix takes the privacy of its users seriously. The highest level of privacy must be available to all users without exception, whether they are technologically competent or have no idea
 how cryptography works. A PerFix user should not feel pressure on their habitual rhythm of life and their expenses due to the risk that other users may find out about them.

Decentralization
PerFix aims to provide the maximum degree of decentralization in both network security and code development. The hybrid POW and POS consensus algorithm prevents specialized
 mining hardware (ASIC) from dominating the network and allows for a fair distribution of rewards for finding new blocks. In addition, development and research are carried out within
 the framework of global cooperation and are carried out with maximum transparency. Each development decision is open to public discussion and voting.

PerFix development and research
Subnet, smart contracts and decentralized applications
PerFix is launching a subnet and its own Gas Token PFXT on the Avalanche platform, this will enable the project to scale. PerFix users will be able to implement fast smart contracts for
decentralized applications with configurable fees and other benefits of the Avalanche network. To pay for Gas, users do not need to purchase an additional asset, all transactions will be
 made with the PFXT token. To convert PFX for the PFXT token, an autonomous decentralized exchange office will be launched.

Neural network and artificial intelligence
Inspired by the successful experience of fellow programmers, PerFix begins research aimed at launching a neural network. Artificial intelligence successfully copes with some tasks,
 including helping users with code generation. Artificial intelligence that will generate the smart contract code in the Go (programming language) is the goal of our research! In our
opinion, this technology will give a large influx of new users to the sphere of the blockchain and will make it easier for developers to perform some tasks.

Fate of this asic is sealed after fork, no asic is good for crypto,

And No GPU is good for Crypto neither, only decentralization is good for crypto, all major coins sooner or later should switch to POS instead POW, its the only way Crypto will rule the future.

Hopefully this bad boy will mine with 6 GPUs since it's specifically designed for mining. If it does indeed work with 6 GPUs then it will be my first choice to pair with a nice Ryzen 8 thread CPU for mining XMR or other CPU coins.

http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=882

Has anyone found them for sale yet?

Only issue is the cpu cost for this mobo, the cheapest Rizen 5 cost 160$, its expected soon a Ryzen 3 but i doubt could beat an intel Pentium at 50-60$, depends on how stable is this mobo and how much will cost the full setup: mobo+cheapest cpu+ 2-4GB Ram.

I'm very interested, need some details please:

Watching the Photos and reading your post, I guess your offer is the following:

A PCIe Switch-USB PCIe Riser combo board

and

a Custom Motherboard based on some low-end SOC with 8x PCIe x16 slots and maybe a integrated PCIe switch.

What are the specifications from the Custom Motherboard I need to know before consider your product:

CPU/SOC: ?

Memory (RAM) on board or slots ?

Boot method: USB, DOM, Integrated DOM ?

Supported OS, is a custom-kernel OS provided (to deal the 8 GPU restriction)?

About the Switch-PCIe riser, more details about the card (actual PCIe lines in use, Supported OSs, etc).

may you shown us a video on a working setups please?

I could order 150-300 from either solution (before qualification test - Barebones Boards Only, not interested on the "Case").

I was working on a similar solution as stefanop (we are far away to have it ready) our setup is a PCIx1 child board that plugged to the motherboard and linked with eSata Express cables to an board using moreless the same chip in 1-3x switches ( PI7C9X2G404SL ), with 3 PCIe x1 ports with open ends so the GPU are plugged directly to the PCIe Swith board 3 GPUs (to keep the board practical for production, each board is about 9" and provides about 1 inch per gpu clearance for cooling, is powered by the eSata Express cable draws no power from the motherboard, and we hope it could be stable enoug. my plan is to plug 6 of these on Biostar Motherboards (assuming we solve the bios issue), each 3 ports board inlcuding cable has a BOM cost about 45$ (not including manufacturing) so out target numbers are close to that from stefano, of course I follow stefano development singe he has solved the gruesome dirty development we just started, in case their boards are good enough I'll not mess with my design and buy/commission from stefano.

I'd like to know about stefano approach to solve the link issue (custom flat ribbon cable, eSata Express, U.2 even multiple USB-C are valid as long has enough lines to full link the PCIe port (18-20 lines total, but it could be less w/o redundant lines, but not so few as with USB3 10 lines).

[...]

Setup is built around a 8 GPUs per daughterboard(the actual board I'm building). Two of my boards are connected to the mainboard (~$150). My current estimates are around 150 per board..so 300+100 = $450...I guess my estimate price is a bit too low for you then  huh Wink The current board I'm testing can physically connect a total of 18 GPUs since it has two extra PCIE slots...youll will just need risers for that last two (there is a possibility a future BIOS update I could make it to post with 3 or even 4 of my boards for a total of 32 GPUs, but I'm just working on 16 for now...plus I would need to work closely with miner devs for anything more than 16...I have slowly hinted them improvements which they have already implemented for multi GPU setups in the past year).

Also the board has status LEDs per GPU lane...if a GPU goes down you'll know right away which one it is, and yes if one GPU crashes the board will still work. This is no different than any other mutigpu setup, other than it having just more GPU lanes. Your doing something wrong if one GPU crash brings down your whole system.

Keep in mind that this price is mostly dependent on the quantities I can order for parts on the first batch. Obviously more boards = less price per board. I am also pretty much charging the cost of components + a small profit margin for me. The design + dev + testing + prototyping etc is all done by me so thats why I can price it so low.



I could find someone interested on 300 of these switches, or maybe a revision since we are on the same R&D line we have some ideas about the switch-gpu link (the cable) our biggest issue to date, but we are faraway from have it ready. now working on other support H/W as Rig Resseter (with ESP8266/Relay modules) and our custom PSU breakout since none in the market satisfy us, even today we considered to integrate the ESP8266 with the PSU breakout thus having an integral Rig Manager, this is not rocket-science compared with the Switches.

I predict everything is going to crash dramatically in the following days and weeks. Crypto has a balance problem with running between absolute bearish and absolute crazy bullish. So we again ran too far too quickly and it's all coming down.

BTC back to 750 at least.

Most alts 30-40% drop....probably much more.

Seems you use Marxist analysis, you (as everyone who believe in marx and its economic thought school) are wrong.

You're not even close to what happens to cryptocurrencies.

Cryptocurrency is a phenomena just exploding, the most know is Bitcoin but bitcoin has serious issues about scalability, this will drive money to AltCoins, the most solid (well planned) are ETH,Zcash I bet on ETH, I've 4x mi worth since I decided to bet in eth and it will continue to grow much faster than any other crypto as the 'experimental failure' ghost vanishes .

all cryptocurrencies dont represent more than 0.0001% of the fiat in the world, all we know with the time Cryptocurrencies will be 100% of the money used, this is an prediction for the next 20yr as much long to be verified, on that time Bitcoin will be another cryptocurrency (heavily forked) among the sea.

Current BIP dont really solve the scalability issues bitcoin has, as SegWit only hides it, and B.U. only make it worst(very slow) on the long, bitcoin is ransomed by chinese miners not the community, this is the big problem, and those miners use to be chinese big hogs -mostly-.

The only true Economic though school is the Hungry, efficiency and productivity e.e. are just politics and vanity.

I've a different theory, a Bitcoin crash will skyrocket Alt-Coins, specially ETH & XMR.

Bitcooin has a 2big issue: mining & Chinese miners, as collateral Bitcoin transaction cost has become unpopular driving users to Altcoins.

ETH isn't see now as a failed experiment, but as a resilent coin will be the one winning the most CAP from bitcoin stampeede.

Unless you're handy on H/W issues (as miss configuration, jumper settings, cmos battery) keep away Refurb Mobos, is not the same as a refurb Phone, when someone returns a Mobo is due some issue either inherent to the MoBo (manufaturing deffects) or caused by them (miss configuration is the most common), so those Mobo even if you're lucky enough to get good ones you'll have to invest time (and patience) dealing with the issues that originated its return, or maybe are not returned HW but MOBOs which boxes where opened due acidents, or Mobo from some defective Batch.

Whatever unless you know what are you doing dont bet on refurbs Mobo.

No Problems with CPU, RAM, even HDD.

Ahh with CPUs keep away overclokeables ones (those with an "K" at end) usually have been abused and its silicon is fatigued, Also Xeon CPUs the used ones comes usually from Rendering Farms, where they use to run 24x7 at full load.

Re: 5 or 6 GPU Motherboard Alternative to H81 BTC Pro and ASROCK Anniversary Edition
by
acostaja
on 18/03/2017, 14:54:53 UTC
ASUS PRIME H270-PLUS 109$
MSI H270 TOMAHAWK ARCTIC 125$
ASROCK H270 PRO4 112$

both 1151 socket & 6 PCIe 3 slots (same Offer as Biostar which should be much cheaper), reference price from AMZ

Gonna be hard to drive 6 GPUs from 5 PCIe slots.

Please only recommend boards you know work.

For instance I have a board with 7 PCIe slots and 2 m.2 slots that theoretically could drive 9 GPUs.

Realistically it can only drive 4.

First you cant populate any M.2 with NVMe w/o account for PCIe lines (and PCIe slots), you should use M.2 Sata SSD.

Whatever nobody who want to earn money will put nothing more than a cheap usb3 16gb flashdrive on it, so discard the M.2 interference.
You should setup PCIe to PCIe v2.0 in bios.

Specifications for Asrock H270 Pro4 are wrong at amazon.

but these are verified:

ASUS Prime H270-Plus
>>> 6 PCIe slots: 1:x16 1:x4(x16 slot) 4:x1
https://www.asus.com/Motherboards/PRIME-H270-PLUS/specifications/


MSI H270 TOMAHAWK ARCTIC
>>> 6 PCIe slots  3:x16 3:x1
https://www.msi.com/Motherboard/H270-TOMAHAWK-ARCTIC.html#productSpecification-section

All based the on Intel H270, better chipset than as Biostar's TB250 H250.

However, I suggest caution to invest on these MoBos as soon will be available cheap PCIe Switches for 8+ GPUs from at least two vendors, one of these seems is regular to bitcointalk.

Re: For the first time in a while... seems like there is a shortage of miners

Gentlemen, I'm new this forum, but I've about 2yr on criptocurrency after being a bitcoin adversary (I'm very conservative about money) by about 4yr, now I´m a bitcoin-criptocurrency advocate.

I like to read analysis and predictions but rarely I consider, becuse these most of the time these fails or are biased on purpose to handle some market or build matrix.

IMHO AltCoins specially ETH and XMR will raise faster in price than Bitcoin, key factor in favor to ETH/XMR is TRANSACTION COST (also transaction speed), Monero also as addon has its extra annonimity but on the long run this annonimity maybe it achiles heel.

At some point the network will rise ETH and XMR difficulty this is the only redflag I see on the upcoming months, but that willonly means less coins that sure will sell twice than today, Mining with GPUs and ALTc wont ever be the same as it was with Bitcoin, alcoins only will raise difficulty in proportion to GPU efficiency while rewards may down (I speculate a dynamic reward system will raise at anytime along alll the alt coins).

Current profitability wont last, that's true, since money attracts money this mean the hashrate to rise (and later the difficulty), but also the transactions will raise fast because Bitcoin's ills -mining, speed, safety privacy -, the time ETH and XMR where seeing as failed experiments left far behind.

I dont mention Zcash and others since I haven stuty it enough, but I'm confident with this prediction: AltCoins RISE its inminent will last unles *unlikely* Bitcoing solves its mining I'lls.

Factors Pushing AltCoins:
  • Bitcoin Mining Ills (neither B.U. nor SegWit will solve the root cause: chinese mining hogs),
  • Bitcoin Transaction Cost (collateral from Mining Ills)
  • Trust (now ETH and XMR and Others arent seen as experiments)
  • Transaction Speed (Ok it depends on how much Atl Coins Grew and its mining grew but with balance it will be favorable by long time)
  • Privacy

Beyond the convenience for rig management, it also could save few $ in lan ralated stuff (still have to check feasibility)


I would recommend you look at the Simple Rig resetter made and sold by Tytanick in the threads here, especially if you plan to scale your farm up, as his device can manage 8 systems for an asking price of $95 or $12 per system, and if you scale up from there, the cost per system can go down to under $8 per system.

Thanks I'm aware of SimpleRig, but a humblke ESP8266 even w/o serial interface its cheaper (6$) widely available, and adding a 1-2$ serial interface it could eliminate wired ethernet or gimme an alternative access to the OS Shell.

thanks, what I see is 450-500 kbps peaks, that could be problematic for the ESP to handle.

that peak is when i logged in into the mining rig using teamviewer ...
during the mining , sending data is never go over 80 kbps , receiving is stay stable around 24-30

Ahh, Ok, so it still  plausible to do with an ESP8266

You have to make sure you are disabling all windows updates , automatic driver updates and all communication with microsoft servers



I'm not aiming at windows based rigs, while there are a serial-lan adapter for windows, I'l plan to use Linux where almost the only thing I need to code/buy are the ESP8266 itself, since the libraries to bridge tcp/ip to a serial port already exists and are somthing I dont need to seek for help, I dont use windows.

P.D. I dont want to compete with anybody here.

I give you the Idea (maybe later I'll share the code too), if you want to adopt it instead another similar solution commercial or DIY its something you have to do by you own and by your own risk.

Rig badwidth usage
by

on 15/03/2017, 17:27:26 UTC
Hello friends 1st post.

I'm a semi-retired IT engineer I develop both hardware and software, now I'm interested to mine Alt Coins and I'm in planning stage for my first rigs, I passively read most thread related to the Rigs, its hardware, software and management.

I reserve the details on my mining operation I consider it has no sense to share this details, but I could share with you the developments related with it I'm considering.

I have a Question, what's the bandwidth used by the tipical rigs while mining:

Monero:
Ether (any flavor):
Zcash:
Pascal:

These are the cryptocurrencies I want to mine (at leas at the begining), of course if you have data on other currencies are welcome.

Please dont forget to detail the scale used: bit per seccond, byte per secconds, byte per hour etc, and how many GPUs are active and the hasrate at which this traffic was metered.

Why I'm asking this for?

- Obviously this data is not available on the threads I've searched.
- I plan to use cheap handy ESP8266 dev boards to manage each rig:
The ESP8266 Can be easy programmed in arduino or freeRTOS to do the following:
  • Reset/Shut Off on N conditions monitored
  • Relay environmental data as: temperature, humidity, voltage
  • Provide TCP/IP connection to the internet (115kbps) -on linux hosts-
  • provide access to the system terminal -on linux hosts-

The best part, is that those modules can be purchased by 6-7$ as Dev Boards at AliExpress, eBay, Amazon and already includes (have to solder nothing): Relay, Temp, humidity sensor, some leds (useful to identify a Rig if you have a farm), and can be powered by the 5V std by lead from the main atx PSU. a TTL-USB interface if terminal/tcp-ip services are required also is needed (also for programming), these also are cheap cost 2-15$

I'm asking since coding in arduino its easy, but may limit the network speed to about 115kbps, with RTOS it could be much faster but RTOS its more complicated and not as easy as the Arduino environment.

Beyond the convenience for rig management, it also could save few $ in lan ralated stuff (still have to check feasibility)

THANKS
