ECC in Intel core 7-8th gen

Hello. Im trying to build home NAS. Looking at mainboards with either c236 or c246 chipset. It supports ECC memory. Intel ARK shows MAANY Intel Core, Pentiums series supporting ECC memory.
But MANY forums and so on always say "oh only Xeons support ecc". Intel forum itself dont give clear answer. I dont want to buy ECC mainboard, ecc ram and then cpu that would not work... Maybe when Intel states ECC supported they mean that cpu works but ecc feature is not used? Xeon is too overpriced for me and i only use it for file sharing not to mine bitcoin :D
Can anyone confirm that 7,8th gen intel cpus support ECC feature?

AMD Threadripper 3970x - My adventure so far (Will edit as I go)

I own a gaming community called Unknown Skies gaming (For a little Context) and we are planning a server upgrade. Currently we have a Dell R620 with Dual E5-2690 V2's Running @ 3.3Ghz, has 196GB Ram. The game we host on this rig is called Empyrion Galactic Survival.
The reason for the upgrade is currently the server just isnt high end enough to continue supporting our target playerbase of 100 players, and Performance has dipped due to the game being alpha and the devs are not doing much to improve server side efficiency. Back in 7.0 we could host 150 players on this machine, now it struggles with 60... Yeah big change in 2 years.
After a lot of research... I can clearly see Intel Xeon Gold 6154 CPUs (2 of them) do not outperform even the R9 3950x according to passmark. The price of these used intel servers is stunningly high on the used market... Dual 18 Core XG 6154 Processors with 128gb ram (Dell R740 I think, feel free to correct me) cost right around 10,000$ USD Used give or take 1000$ or so... And get stomped on by an 800$ Single Socket CPU... Thats new and has a warranty... I get that it doesnt support as much memory... But Dang...
So I looked into threadripper... HOLY SHAT!! The 3970x hits 60k+ in passmark... And the ENTIRE system with a custom cooling loop is less than 6 Grand? Thats nuts to me! Amazing Deal! Im sad all my servers and rigs are intel hahahahaha.
What we need, What im aiming for, and my thought process - Feel free to leave thoughts and suggestions..
AMD Threadripper 3970x (Because High Per thread throughput matters due to shit code, and more players on a playfield means more cpu usage on that thread, Lots of threads matter as every playfield opens a new PlayfieldServer.exe and is its own instance so the more spread out players are, the more cores you need to spread out workload. 32 cores 64 threads... NICE)
Corsair Vengeance LPX 256 GB (8 x 32 GB) DDR4-3200 Memory (Each player uses around 1-3gb ram, 2 on average, goal was 100 Players)
ASRock TRX40 TAICHI ATX sTRX4 Motherboard (Thought this was a solid selection given the options I saw)
EVGA 1000 W 80+ Gold Certified Semi-modular ATX Power Supply SHOULD be sufficient with a closed loop water cooler, all SSD's and not requiring a gaming GPU (Plan on a 1050ti / 1050 at most)
Case im using is a modified 4U rackmount case with 3x 120mm fans going in the front, radiator behind those. Could NOT find one that I didnt have to modify. Went with El-cheapo option cause imma be drilling it and modding it internally - Rosewill Server Chassis Server Case Rackmount Case for Bitcoin Mining 4U off ebay I think it will work, and if not I have a file server that would LOVE the home LMAO. So it was well worth the Chance.
Water cooling Solution I settled on was a Thermaltake Floe TR4 Edition. I thought about using a Custom Cooling loop, but by the time I priced everything out the way I would do it... It came out to like 500$ ish LMAO. The above cooler From what I can tell should be sufficient, and should fit in the case i chose. Tight fit, but should fit.
Im excitedly looking forward to the build :) Anyone have any experience with any of this and care to chime in?

inherited 24U of servers, etc in co-lo... another revenue stream or another business idea?

A client/buddy is sun-setting their business so I have inherited about 24U of their servers (server & workstation grade components) and networking equipment (all 10 Gbe ready) in his co-lo. I can keep them in his cabinet/co-lo and run them for the next year or so, but he asks that I keep my bandwidth usage low, about 10% of his plan's bandwidth (100 Mbps, I believe, so only 10 Mbps). Servers are of the Intel XEON X5600 and 12/24/26xx v1/v2 series, 48 to 192+ GB RAM and up to 30 TB of raw storage. Any ideas that can leverage these servers, yet is low bandwidth/traffic friendly so I can add another revenue stream for my one man MSP business? Or maybe another startup/business idea (MSP related or not)? I'm up for trying anything that brings in even the smallest amount of recurring revenue (except bitcoin mining, pr0n related or anything illegal).
P.S. - All of my clients are small and all are using cloud services for their IT needs, so I don't need nor want to use the servers for this part of my business (their needs are met, doubt any would pay more for whatever I can drum up with these newly inherited resources).

My Beginnings

My Current Rack Setup

So, this is the first time I've ever done a post like this to homelab and I wanted to give as much detail as possible.
For this, i'm going to work my way left to right, top to bottom.

Andreas Antonopoulos gets "Satoshi's Vision" completely wrong and shows his misunderstanding of the system. He thinks 1 cpu 1 vote means 1 user 1 vote, a common mistake from people on the Core side.

In this video at the 6m20s mark Andreas Antonopoulos speaks about Satoshi's vision. He speaks about "1 cpu 1 vote" saying that Satoshi designed the system to be decentralized as possible, but Andreas completely misunderstands the meaning of 1 cpu 1 vote. He is falling into the common trap of conflating 1cpu 1 vote with 1 user 1 vote.
Andreas, haven't you even read nChains paper about POW and Theory of the Firm? A cpu is an economic resource:
One of the little-known aspects of bitcoin is the nature of the proof of work system. There are many people, especially those who support a UASF or PoW change that believe a distributed system should be completed as a mesh. In this, they confuse centralised systems with centrality. The truth of the matter, no matter which proof of work system is implemented, they all follow a maximal growth curve that reflects the nature of the firm as detailed in 1937 by Ronald Coase (1937).
The bitcoin White Paper was very specific. users of the system "vote with their CPU power" [1]. What this means, is that the system was never generated to give one vote per person. It is designed purely around economic incentives individuals with more hash power will have provided more investment into the system. These individuals who invest more in the system gain more say in the system. At the same time, no one or even two individuals can gain complete control of the system. We'll explore the nature of cartels in a separately, but these always fail without government intervention. The reason for cartels failing comes down to the simple incentivisation of the most efficient member. The strongest cartel member always ends up propping up the weakest. This leads to a strategy of defection.
No proof of work-based solution ever allows for a scenario where you have one vote to one person. The anti-sybiling functions of bitcoin and all other related systems based on proof of work or similar derivatives are derived from an investment based strategy. Solutions to the implementation of ASIC based systems are constantly proposed as a methodology of limiting the centralisation of proof of work systems as it is termed. The truth of the matter is that the mining function within any proof of work system naturally aligns to business interests. This leads to corporations running machines within data centres. On the way that democracies and republics have migrated away from small groups of people individually voting for an outcome towards a vote for a party, the transactional costs associated with individual choice naturally leads to corporate solutions. In this, the corporation mirrors a political party.
In this paper, we address the issues of using alternate approval work systems with regards to either incorporating alternate functions in an extension of simply securing the network against the use of proof of work systems to create a one person one vote scenario in place of economic incentivisation. We will demonstrate conclusively that all systems migrate to a state of economic efficiency. The consequence of this is that systems form into groups designed to maximise returns. The effect is that bitcoin is not only incentive compatible but is optimal. No system can efficiently collapse into an order of one vote one individual and remain secure. In the firm-based nature of bitcoin, we demonstrate that the inherent nature of the firm is reflected within mining pools. Multiple aggregation strategies exist. The strategies range from the creation of collective firms where members can easily join or leave (mining pools) through to more standard corporate structures
Proof of Work as it relates to the theory of the firm. that are successful within any proof of work system. The system was determined to be based on one- vote per CPU (Satoshi, 2008) and not one vote per person or one vote per IP address. The reasons for this is simple, there is no methodology available that can solve byzantine consensus on an individual basis. The solution developed within bitcoin solves this economically using investment. The parties signal their intent to remain bound to the protocol through a significant investment. Those parties that follow the protocol are rewarded. The alternative strategy takes us back to the former and failed systems such as e-cash that could not adequately solve Sybil attacks and decentralise the network. Bitcoin manages to maintain the decentralise nature of the network through a requirement that no individual party can ever achieve more than 50% of the network hash rate.
In all proof of work systems, there are requirements to inject a costly signal into the network that is designed as the security control. To many people, they believe that the cryptographic element, namely the hashing process is the security feature of bitcoin. This is a fallacy, it is the economic cost that is relevant to the overall system and not the individual element.
The benefits of a hash function are that they are difficult to solve in the nature of the proof of work algorithm but are easy to verify. This economic asymmetry is one of the key features of bitcoin. Once a user has found a solution, they know it can be quickly broadcast and verified by others. Additionally, the hash algorithm provides a fair distribution system based on the amount of invested hash rate. The distinction from proof of stake solution as has been proposed comes in the requirement to constantly reinvest. A proof of stake system requires a single investment. Once this investment is created, the system is incentivised towards the protection of the earlier investment. This leads to a scenario known as a strategic oligopoly game.
The solution using a proof of work algorithm is the introduction of an ongoing investment. This is different to an oligopoly game in that sunk cost cannot make up for continued investment. In a proof of stake system, prior investment is crystallised allowing continued control with little further investment. Proof of work differs in that it requires continuous investment. More than this, it requires innovation. As with all capitalist systems, they are subject to Schumpeterian dynamical change (Shumpeter, 1994). The system of creative destruction allows for cycles of innovation. Each innovation leads to waves of creation over the destruction of the old order.
This process creates continued growth. Proof of work-based systems continue to grow and continue to update and change. Any incumbent corporation or other entity needs to continue to invest knowing that their continued dominance is not assured. In bitcoin, we have seen innovative leaps as people moved from CPU-based mining into GPU-based systems. This initial innovation altered the software structure associated with the mining process in bitcoin. That change significantly altered the playing field leading to novel techniques associated with FPGAs and later ASICs dedicated to a specific part of the mining process.
The error held by many people is that this move from a CPU-based solution into more costly implementations could have been averted. A consequence of this has been the introduction of alternative proof of work systems into many of the alt-coins
These systems have been implemented without the understanding that it is not the use of ASICs that is an issue. It is that the belief that individual users can individually mine in a mesh system will be able to be implemented as a successful proof of work. In the unlikely event that a specialised algorithm was implemented that could only run once on any one machine CPU, it would still lead to the eventual creation of corporate data centres for mining. In the section above, we showed using Arrow’s theorem how only a single use proof of work system can be effective. If we extend this and look at the Theory of the Firm (Coase, 1937) we note that in a system in Litecoin and Dogecoin for example. A00137:
Proof of Work as it relates to the theory of the firm. of prices, reduction could be carried out without any organisation. One issue against this arises from the cost of information. Interestingly, as we move into a world of increasingly more information, it becomes scarce information that is important. As the amount of information becomes more voluminous, the ability to uncover accurate and timely information becomes scarcer. The ability to specialise in the coordination of the various factors of production and the distribution of information leads towards vertical integration within firms. We see this first voiced in Adam Smith’s (Smith, 1776) postulation on the firm:
Everyone can choose to either seek further information or act on the information that they already have. This information can be in the form of market knowledge, product knowledge, or expertise, but at some point, the individual needs to decide to act. There is a cost to obtaining information. The returns on obtaining more information hit a maximum level and start to decrease at a certain point. The entrepreneur acts as a guiding influence managing the risk associated with incomplete information compared to the risk of not acting but rather waiting to obtain more information.
In the instance of bitcoin mining, the firm can increase in size through the integration of multiple specialist roles. Even given the assumption that any one process can run on but a single CPU, we come to the scenario of high-end datacentre servers. The Intel Xeon Phi 7290f implements 72 Atom CPU Cores. Each core runs two threads. Even taking the control system into account, this leaves 142 processes able to run per system. With four cards per RU this allows for datacentre implementations of 5,964 mining processes to run on a pure CPU-based proof of work implementation. One person can manage a small number of mining server implementations within a home or small business environment. In large data centre-based organisations such as Facebook, a single administrator can run 20,000 servers
The effect of this would be one individual managing 2,840,000 individual CPU-based mining processes. This alone is outside the scaling capabilities of any individual. This can be further enhanced as cost savings through the creation of large data centres, management savings and integrating multiple network and systems administrators is considered. As we start to add additional layers we come to a maximum where it is no longer profitable to grow the firm in size. Right up until that point, the firm will grow.

UK Review of Shadow (Fortnite, Forza, Overwatch)

hey guys, This offers you a dedicated computer (Windows 10) in the cloud with:
all for £27 a month. I thought I would try it out and share my experience with anyone that is interested in gaming but doesn't want to fork out £1500+ on a gaming computer. I tested this on a Samung tablet (integrated GPU), Android phone and a desktop computer. After creating an account and downloading the client, I logged in to see the Windows 10 setup screen (What you would see when you build your own Win10 computer).
Once logged in, I tested the bandwidth and consistently got over 980mb in the speed test! I test Fornite on this tablet and was able to play on EPIC settings at 60FPS. Now in terms of input lag, I didn't notice anything of significance. I was able to log in to Shadow from my Android phone and continue the same game of Fornite.
Forza 3 was ultra smooth on the highest settings and I was able to pair my Xbox 1 controller to Shadow to play it. I tried online multiplayer gaming with Overwatch and again was able to play on highest settings with no visible lag and even won a match!
In summary, I would say
Benefits

Rebuttal: EOS does use Public-Key Cryptography (Per the Whiteblock paper) and has close to 4000 PTS (Max)

Introduction

Early November 2018, articles hit the news that EOS is "not a blockchain":
The Research was comissioned by Consensys. From Consensys' homepage, we learn that
ConsenSys is a global organism building the infrastructure, applications, and practices that enable a decentralized world.
If we have a look at the About Page, we learn that
Our focus is on the ecosystem, the growth of the Ethereum network (emphasis mine), and global integration of the benefits of blockchain and tokenization.
The study was done by Whiteblock, the "Scalable Blockchain Testing Platform". If we have a look at the prnewswire press release, we learn that:
Blockchain organizations such as Cosmos, Ethereum Community Fund, Amis, Maker DAO, IMToken, PlatON, Status, Loom Network, Coinfund, 1KX, Transference Fund, Web 3 Foundation, Grid+, MixLabs, Ledger Capital, Enterprise Ethereum Alliance, Google, Microsoft, ConsenSys and Bo Shen - Founding Partner of Fenbushi Capital & Cofounder of Bitshares, along with academic institutions such as Duke, USC, and MIT have committed to contributing resources to develop comprehensive reports based on Whiteblock's raw data (emphasis mine).
So at least a few pro-Ethereum entities have provided resources to Whiteblock. Can we expect impartiality from Whiteblock's research?
Additionally, if we have a look at the report, it was co-jointedly written by two scientist from Whiteblock and two scientists from Consensys:
https://www.screencast.com/t/8niRZaRScVJ
So we have the same party requesting an independent study of a concurrent blockchain and participating to the redaction off the final report. Conflict of interests, anyone?

About EOS and Cryptography:

EOS uses public key cryptography to sign transactions, per the EOS Whitepaper:
https://content.screencast.com/users/ChristopheK/folders/Jing/media/4bf5fb89-c851-450b-abe9-cf50e5691d8f/2018-11-07_0849.png
https://github.com/EOSIO/Documentation/blob/masteTechnicalWhitePaper.md#context-free-actions
Here an overview of an EOS transaction, which includes signatures:
https://steemit.com/eos/@dan/eos-developer-s-log-stardate-201707-9
So this means that EOS transactions signed with a private key are verified using the corresponding public key. This is how in cryptocurrencies, value is transmitted from the owner to the receiver using public key cryptography:
https://en.wikipedia.org/wiki/Public-key_cryptography
If you don't understand this, please read the Bitcoin whitepaper:
https://www.bitcoin.com/bitcoin.pdf
Section 2, transactions:
We define an electronic coin as a chain of digital signatures. Each owner transfers the coin to the next by digitally signing a hash of the previous transaction and the public key of the next owner and adding these to the end of the coin. A payee can verify the signatures to verify the chain of ownership.

Cryptographic Validation

EOS blocks are signed with cryptographic keys:
https://eosio.stackexchange.com/questions/717/what-block-hash-function-and-transaction-signature-method-does-eos-use
The Whiteblock paper says:
This becomes apparent from the substantial reliance on architecture where cryptographic validation is not necessarily instantiated, though rather implemented in proximity.
What does not necessarily instantiated mean? This looks like a rather vague statement where the author isn't sure himself about what he writes.
I think the main beef Consensys/Whiteblocks has with EOS' architecture is that it doesn't do things the way Ethereum does, and hence is deemed "bad".

About the EOS Max Transaction Rate (TPS):

Whiteblock states that their testnet didn't support more than 250 TPS:
As observed in the section on performance, the transaction throughput in the system does not exceed 250 TPS even in optimal settings with 0 ms of latency and 0% packet loss.
To me it seems like it speaks more of Whiteblock's ability of setting up a test net than anything else, because EOS Mainnet already passed several thousands of transactions previously, with the record being close to 4000 TPS (3996 TPS to be exact):

Server Hardware

The servers they have used have, I kid you not, 5-year old specs.
The CPU, an Intel Xeon E5-2667 v2 was released on Sep 10, 2013 (Wikipedia).
The Server, a Dell Poweredge 720, also seems to have been manufactured around that time. You can find videos from 2013-2014 about the server on Youtube.
No wonder they didn’t make it past 250 TPS.

Use of Virtual Machines

While running as block producers, the servers also hosted a set of virtual machines, seemingly to host the clients:
https://content.screencast.com/users/ChristopheK/folders/Jing/media/8b0ac74e-083f-48f2-9897-9153833c74a4/2018-11-04_0910.png
Needless to say, running virtual machines in addition to the block producer software on the same physical machine degrades performance.

Performance Test Inputs

Page 13 features tables with input variables getting changed for each test case. Oddly enough, most tables specify that two TWO input variables were changed for each test case. How from this you can deduct which variable has an influence on the output is a mystery to me.
https://content.screencast.com/users/ChristopheK/folders/Jing/media/db889932-697e-45ec-93a0-54b4e63b999f/2018-11-04_1055.png
However, I think this is an oversight due to sloppy copy-pasting among the tables, and most likely the Network Latency has been kept constant for test series B - F.

History

Edit: added link to Whiteblock paper, spelling, less aggressive tone.
Edit 2: Added server info
Edit 3: Added virtual machine info, links to server hardware, spelling
Edit4: Added introduction, information of performance test inputs
Edit 5: Updated sections About EOS and Cryptography and Cryptographic Validation, About the EOS Max Transaction Rate (TPS)
Edit 6: Some formatting
This post is still work in progress.

Can anyone help me calculate the hash rate of my friends server? I want to buy it, but it may be a bad deal. Noob help needed!

Any help would be greatly appreciated. I am looking to buy a server from a friend, and possibly mine bitcoin with it. I cannot find any way to calculate the hash rate of the server, so I would appreciate any help I can get. Here it’s stats:
Intel Xeon D-1520
4c / 8t
2.2 GHz
32 GB DDR4 ECC 2133 MHz
SoftRaid 4x2TB SATA
I know there isn’t a way to calculate the exact hash rate of this setup, but it would be amazing if someone could give me an estimate.

Wanted a GTX1080 but only had a budget of £27...

I wanted to ascend but I dont have the money to pay £1k upfront. I came across this service called "Shadow". This offers you a dedicated computer (Windows 10) in the cloud with:
all for £27 a month. I thought I would try it out and share my experience with anyone that is interested in gaming but doesn't want to fork out £1000+ on a gaming computer. I tested this on a Samung tablet (integrated GPU), Android phone and a desktop computer. After creating an account and downloading the client, I logged in to see the Windows 10 setup screen (What you would see when you build your own Win10 computer).
Once logged in, I tested the bandwidth and consistently got over 980mb in the speed test! I test Fornite on this tablet and was able to play on EPIC settings at 60FPS. Now in terms of input lag, I didn't notice anything of significance. I was able to log in to Shadow from my Android phone and continue the same game of Fornite.
Forza 3 was ultra smooth on the highest settings and I was able to pair my Xbox 1 controller to Shadow to play it. I tried online multiplayer gaming with Overwatch and again was able to play on highest settings with no visible lag and even won a match!
In summary, I would say
Benefits
Negatives

So my college have that IBM cluster, could it be useful to mine?

My college have an IBM cluster for the students to make some tests and I'm thinking about using it to mine. I just have to say it's about my research, but i need to know how to use it to mine, can someone help me out? (I'm new in this bitcoin issue, I've read the FAQ but I need more answers).

Estimating the marginal cost of a transaction on the Bitcoin (Cash) network

Recently, the mempool has not been clearing with every block found. Should we immediately raise the block-size? Perhaps put plans to make the easy relay of sub satoshi/byte transaction on hold?
Assumptions:
Step 1: find the price of storing a transaction
Searching NCIX:
Calculate the price per TB, assuming 1 is 6 drives are used for parity (30 bays usable storage)
Estimate the UTXO premium:
As you can see. miners have a strong incentive to offer free UTXO consolidation transactions: and require bulk UTXO fanning transaction to pay a fee of 494.86sat/kB -- about 0.5 sat/byte. ((0.01249USD/kB)/(2523.96USD/BCH)*100,000,000sat/BCH)
Fees are no where near that high due to the block subsidy. For an 8MB block: 1,250,000,000 satoshies/ 8000 kB -> 156,250sat/kB; or more conventionally: 157satosies/byte.. Note that the block subsidy per kB goes down with larger block-sizes.
Step 2: Estimate Bandwidth costs
Disclaimer: I am not too familiar with commercial bandwidth plans
Exercise to the reader:
Re-do these calculations for hobbyist hardware and internet connections. You probably have to assume a smaller block size: such as 100MB.
Disclaimer: I later learned the site I was using for prices (NCIX) was bankrupt. Not sure how much that would skew prices.
