Log of AMA with Skycoin

boldninja Let's all give a warm welcome to @synth from SkyCoin.net and for taking the time to do this AMA
synth *hello
mike Hi Synth
jakethepanda Hey @synth
thrice.pi Hey synth
dr10 Hi
boldninja I think we can start - you guys know the drill. Give him some time to respond (no more than 2-3 questions on backlog so he can catch up)
dr10 How would you - shortly & in easy words - sum-up the advantages of SkyCoin to magazines and non-crypto people?
mgaruccio Can you explain a bit about the mesh net? Is it just an mpls network between nodes or is there something deeper going on?
michaelthecryptoguy Whassup @synth
tranzer hi synth. I have a question - are those coins that are not in circulation in any cold wallets since only a portion is currently available according to CMC? What would you say is the 1 unique feature that Skycoin has?
synth It is very difficult, because Skycoin is a very large project and already has +6 years of development. Different parts of the project have different objectives.
The cryto, coin part is about solving the problems with the existing consensus algorithms. Being able to do +300 transactions a second, transactions in seconds instead of minutes (faster than credit cards), eliminating miners, eliminating block rewards (eliminating inflation) and eliminating 51% attack and the other problems with mining.
then there are other repos and experimental projects under github.com/skycoin such as a meshnet and distributed VPN prototype, where people will be paid coins for forwarding traffic. Also prototypes of distributed social media application, with peer to peer data replication and different experimental projects. Research into immutable data structures for next generation internet. Some of them are very radical.
dr10 How does the Network consensus algorithm Obelisk work and differ from widely known algorithms like Proof of Work and Proof of Stake?
mgaruccio So how much exists today? Could I build an app on the platform if I wanted to?
mike In terms of the rate of progress, what is currently your greatest limiting factor - like funding, manpower, currently available technology?
synth
Can you explain a bit about the mesh net? Is it just an mpls network between nodes or is there something deeper going on?
It is not actually a meshnet. It is software defined networking, it is much more powerful than just meshnet. Its a new type of networking and new completely new protocol and networking namespace, independent of the existing internet.
It supports source routing, while the existing internet does hot potato routing, so never achieves optimal latencies.
It supports multi-homing, which IPv6 does not (Which is critical for when we have gigabit or terabit networking and multi-redundant bandwidth paths)
It has default oppurunistic crypto, both link layer and end to end; so everything is encrypted by default, unlike the current internet.
It has store and forward networking and will operate in Africa or even under conditions where latencies are in the minutes or hours and packet loss is excessive. Where existing protocols cannot operate reliability. It is much more robust than IPv4/IPv6 or TCP/ip
It has improved privacy. If a packet takes a route that is 10 hops, each hop only knows the previous node in the route and the next node in the route. It is not like IPv4 where each packet gives the source and destination. The privacy level is something that does not exist on the current internet.
IP addresses are replaced by public key and no one can read traffic to a destination, without knowing the private key of the public key that identifies the destination. The system does not need 3rd parties or certificate authorities. The design is a revolution.
are those coins that are not in circulation in any cold wallets since only a portion is currently available according to CMC?
The coins are locked into 100 addresses, each with 1 million coins each. And they are released sequentially.
There is a complicated locking procedure and releasing new coins requires unamious consent and a shared secret among a group of developers. Anyone in the shared secret group can block distribution of more coins (to stop the problem that killed NXT). So by design the coins were supposed to be difficult to distribut, there had to be a good reason or justification before a distribution would be approved.
mike What are the hardware requirements to operate a wireless Skywire (the name for the protocol described above) Node?
arc-over-water nxt i think is doing ok..
synth
How does the Network consensus algorithm Obelisk work and differ from widely known algorithms like Proof of Work and Proof of Stake?
PoS and PoW use miners. Miners receive new coins every block as a block reward. So miners are making money and will fight to control the network. An everyone will suffer because the newly created coins represent inflation.
Skycoin was designed to eliminate mining and eliminate the inflation. No block rewards, no new coins. And we needed to develop a new consensus algorithm to do that and there are only a few methods that work, for these constraints. The consensus algorithm is based upon Ben-Or's randomization procedure for achieving consensus in a distributed system, with some improvements for detecting adversarial or malicious nodes who are trying to prevent the consensus process.
There are white papers on skycoin.net about the specifics. I would call it "network consensus" and it uses a sort of Web of Trust (WoT), where if the people creating blocks are doing a bad job or attacking the network, then the community can get rid of them. At the same time, the people who control the network, do not have any real power to attack the network except by slowing down transactions and being annoying, so even if they become malicious the only issue is how to get rid of them and select new people.
mike Any idea when Skywire will be released and ready to test on hardware nodes (testnet or mainnet)?
mgaruccio So if there is no block reward what is the incentive to run a node?
vega What will be the actual function of Skycoin (the coin itself)? Will the coin be used as currency, as transfer of value in and between all these various developing functionalities, semi-separate projects to tie them all together or it's function will be more limited?
michaelthecryptoguy Do you have an idea on the specs of a node that would be required? In the beginning? What about with 10,000 users? (edited)
synth
nxt i think is doing ok..
There were three people that each owned 30% of the coin. One decided he wanted out and began dumping. NXT was over 150 million I think. When he started dumping, it basicly killed NXT.
Skycoin's distribution was designed to stop dumping by the founders and early people.
After Skycoin gets to 30% of the total coins distributed, there will probably a hard time lock on the remaining coins, so that a maximum of 5% of the remaining coins can be released per year. So the distribution for the other 70% of the coins will take a minimum of 14 years (and could be longer).
We cannot even sell the rest of the coins, because if we sold 10% of the total now at $5 per coin, it would be 50 million or something and we cannot spend or even use that amount of money. Not at this stage.
Ethereum spent 30 million or 70 million in their first year or two after the ICO and then nearly went bankrupt. Silicon Valley wages and offices etc. We have been very conservative and have kept costs down and kept them responsible. Now we have coins like EOS and they want to raise a billion dollars and have not produced anything yet, do not hav a blockchain and I have no idea what they would spend that money on, but they are throwing $350,000 parties in time square for marketing/PR etc...
arc-over-water what prevents you from selling? anybody can spend that amount of money?
nxt is a newer platform than sky, market value is $220 million plus $166 million, I get what you are saying but the evidence is wrong. Community is huge and active in Nxt. But you say it is killed, i dont get it?
synth
What will be the actual function of Skycoin (the coin itself)? Will the coin be used as currency, as transfer of value in and between all these various developing functionalities, semi-separate projects to tie them all together or it's function will be more limited?
Yes. Bitcoin has no purpose. An altcoin does two things - check your balance - send money to other people
Two features - check balance - send
For a coin to have value, people need to be forced to buy it to consume specific services. There has to be stuff for people to spend the coin on, that there is demand for.
So Bitcoin is really just a purely speculative asset. It generates no cashflow and its value is determined by perception or social convention.
Ideally, Skycoin would start off as a "better Bitcoin" (faster, more secure, new algorithm, simplier, etc), then over time we would build up an ecosystem and have some type of backing and tie the coin's value into the network and usebase.
The mesh netork (skywire) is good, because it gives something for people to do to get coins and it allows people to consume the coins. You can run your internet traffic through a VPN that tunnels over Skywire and maybe it will be a nominal amount (actually absurdly small amount of money), but there would be real economic activity and a real userbase and community using the coin. Not just speculation.
Later on the scope is much wider.
arc-over-water So the skycoin wallet will be a VPN for our internet usage?
synth
nxt is a newer platform than sky, market value is $220 million plus $166 million, I get what you are saying but the evidence is wrong. Community is huge and active in Nxt. But you say it is killed, i dont get it?
What I am saying, is that NXT would be a lot further along than it is now and probably around where Ethereum is, except for that mistake in the distribution and keeping it too concentrated. It set them back by years. They did not consider what the impact on the price would be, over the long term, when one of the early whales started selling off or decided he wanted out.
arc-over-water But they did the same again with IOTA, same lead dev.. Its over a $Billion
they released and let the market price distribute
synth
So the skycoin wallet will be a VPN for our internet usage?
The VPN is just one application, that uses bandwidth over Skywire. There are several things in development.
This is a BBS like 4chan, that is completely distributed, with CXO. https://github.com/skycoin/bbs
It will run over Skywire also, This is like building a whole new internet from scratch. The apps that run on it are going to specialized and privacy focused, etc GitHub skycoin/bbs Contribute to bbs development by creating an account on GitHub.
mike So Skycoin is a Proof of Resource coin where its value is actually backed by provision of a useful service, in this case private and secure networking? Are there plans to add decentralized storage and even distributed processing to it?
arc-over-water so these 100 separate million coin accounts will be 100 ICOs or how is the distribution patterned? is it written into the code or up to the devs?

synth
So if there is no block reward what is the incentive to run a node?
running a consensus node does not cost anything. You can run it on a raspberry pi.
The important thing is that if the people doing consensus are doing a bad job, that the community can get rid of them and replace them. The other important thing, is that they can be audited and determined automatically if they are obeying the protocol.
the miners in skycoin are not very powerful and cannot do anything except slow down transactions. They are unable to spend other people's money without their private keys, so the consensus/mining nodes are almost irrelevent. It is not like Bitcoin where the miners can hold the network hostage or act selfishly (driving up the transactions fees for their own personal benefit and delaying any innovations that would improve bitcoin for everyone, etc).
So Skycoin is a Proof of Resource coin where its value is actually backed by provision of a useful service, in this case private and secure networking? Are there plans to add decentralized storage and even distributed processing to it?
We have decentralized storage, which is called CXO. But only the bandwidth is monetized by Skywire. We do not nickle and dime and try to attach a coin cost to every API call. Everything that should be free is free. So its a different philosphy.
On top of CXO we also have distributed social media applications (simmilar to Steemit)
CXO is very similar to IFPS, but simplier and designed for our internal infrastructure and with our crypto standards, instead of being a mismash.
mike Is it possible for Skycoin to choose the best paths and route around bad or slow nodes as damage to the network, in effect reducing their impact on consensus?
looks like you answered the question above while I was typing...
tranzer How many tx/s can skycoin handle? What are block times?
thrice.pi 300 right? ^
arc-over-water on your website it says you will have a NON- Turing complete lisp language?
synth
so these 100 separate million coin accounts will be 100 ICOs or how is the distribution patterned? is it written into the code or up to the devs?
We will have a distribution page, up on the website soon. Its complicated.
Skywire, is designed to pull coins out of circuation, through a sort of tithe on network activity and it does automatic buy backs effectively. So the distribution will actually peak and then decline. But one distribution is from the locked coins, and the locked coins are freed, then circulate, then end up at the foundation (from the skywire tithe are pulled out of circulation), but still count towards the free float.
The coin holders also receive a coinhour dividend and there will be a market rate conversion between coin hours and Skycoins and coinhours are the actual currency for the Skywire network. If you do not have enough coin hours, then you sell Skycoin for CoinHour at the market rate, to purchase bandwidth; but if you have a lot of coins then you have enough coin hours for downloading movies or VPN or whatever you are doing and it is essentially free.
So there is a dual level economic structure. Both with coin buybacks to pull coins out of circulation and with a dividend or incentive to encourage users to hold the coin if they are using the network.
arc-over-water so there will be two currencies, holding one reserves the other
synth
Is it possible for Skycoin to choose the best paths and route around bad or slow nodes as damage to the network
Yes. This is very important.
The person dialing a connection, chooses the path of the connection!
You can choose the lowest latency path for video games or Skype, and choose highest throughput paths for video downloads etc. Or can choose paths through specific nodes or facilities or countries, for security concerns and to minimize the number of points that the traffic could be intercepted at.
mike Will Skycoin still have the node subsidy plan for setting up and registering the mesh nodes like originally planned?
dr10 When do you plan to be able to present your planned technology and services to the masses? When can they use what you try do accomplish?
synth
on your website it says you will have a NON- Turing complete lisp language?
That is probably an error. LOL. We will have a new website soon.
There is no scripting language on the skycoin blockchain. Each transaction is constant time (for efficiency and security and to achieve the highest transaction rate and to keep the coin simple).
However, we have a language called CX in development, which is a next generation language that is beyond "smart contracts" and the toy things on ethereum. It uses immutable datastructures and is something completely new. Most of the skycoin "smart contracts" will probably be off blockchain or in personal blockchains and we do not want to shove all the data onto the main chain, because forcing everyone to download everyone one elses contracts it the world is just spamming the blockchain to death. There are better ways to do it.
Will Skycoin still have the node subsidy plan for setting up and registering the mesh nodes like originally planned?
Yes. We are going to get from 20% to 30% distributno of the coins, through network incentives for people running Skywire nodes, consensus nodes and services.
I think this is going to be massive for marketing. And it is the best way to get the coins out to the users, instead of all the coins being held by whales
samuelvihollandia I read how you suggest Skycoin could be used for VPN connections, is this the largest use case you see?
arc-over-water Maidsafe has been working on the redesign of the net for about ten years, what are you doing the same and what different?
synth
I read how you suggest Skycoin could be used for VPN connections, is this the largest use case you see?
No. This is just something easy, that we have working. Its not the largest applicatoin at all.
80% of internet traffic right now is bitorrent and the bitorrent sites are being systematically shutdown and driven off the internet. They wont go away, but will jut go underground. What.cd (largest music tracker, with 800k people) was just shut down, bakabt (largest anime tracker) has gone closed registration, Nyantorrent etc...
User communities of millions of people will be migrating from the clearnet (the existing corporate shit-net) to the "new internet". We are going to see people migrating by the millions, whole user communities of millions of people.
arc-over-water Are you a corporation or foundation or charity? Registered? I am not sure i have seen anything about who you are? What is the dev team size? Background? - Maidsafe is open and clear so is IOTA and Stellar etc. Can you let us know who you and your team are? Especially you are talking about 15 year and up obligations..
techbytes Do we need to hold skycoin to run Skywire nodes or consensus nodes like masternodes from other coins?
synth
Maidsafe has been working on the redesign of the net for about ten years, what are you doing the same and what different?
Maidsafe is in version 2 or 3. Maidsafe will not have a real coin until version 9. Each version takes them about two or three years. Maidsafe will not be "done" or ready for atleast 18 years at this rate.
Skycoin has been in development for ~6 years and the meshnet for 4 years and it will be finished in a few months. To the poin that people can start using it.
Skycoin is similar to maidsafe in the objective, but has a different approach and architecture and primitives. We did not try to do everything, but focused on a smaller, tractable core and got that done.
There will be multiple projects in this space, but few teams are able to plan on the time horizon necisary for building a new internet or able to design each of the components of a system this large, or figure out how to do it so that it is useful at each stage of construction of a project that may take a decade. (edited)
mike Can you see a way for Ark and Skycoin to build on each other in a synergistic manner? I'm all for not reinventing the wheel, especially when it looks like it will be replaced with antigravity like Skycoin.
I see Skycoin as essentially replacing TCP/IP and providing mesh network type functionality at the hardware level, Ark would run on top of it as a top level application layer.
arc-over-water are you up to date on Maidsafe, they are nearly out of Alpha and its more like release early next year? But that being said, Maidsafe says once it is released it is like a virus or AI type, so does Tau Chain, and also Autonomic by HunterMinerCrafter, are we heading towards AI with Maid, Sky Tau and Autonomic?
dr10 smartbridge now! :kappa:
mike So Skycoin would act as a sort of global decentralized cloud server to build on top of.
To communicate, it is more like sharing encrypted files to selected recipients than it is sending messages or hosting sites on a specific server.
synth
Are you a corporation or foundation or charity? Registered? I am not sure i have seen anything about who you are? What is the dev team size? Background?
I think there are over ~60 people who have worked on Skycoin or have made major contributions. Its really a project from the darknet.
Many of the contributors are anonymous. Some of them have security clearances and were in the military industrial complex and one of them worked at the San Diego Naval Defence Research Lab and a lot of the idea for the networking protocols came out of public sector academic researched, funded from there.
We also have a lot of very very early Bitcoin people, hardcore crypto people that predate Bitcoin and an Ethereum core developer, etc..
On the Chinese side we have an early investor in Alibaba and telecom investor. And are doing pilot with china aviation group (owns four publicly traded airline companies) and apparently now Sinopec (which is 2nd largest publicly traded corporation in world).
Then we have people who are part of israeli and US intelligence and are probably doing some sort of money laundering or phychological operations background, who just showed up for some reason. This group seems very interested in the "applications" of these coins and how to improve tranaction privacy and the specifics of the CoinJoin protocol implementation. We got a lot of advice from people experienced in forensic accounting and what they wanted to see and where they felt Bitcoin was deficient and where it leaked metadata.
Then a bunch of PHD level people doing research into distributed database consensus algorithms and another group doing programming language research.
Then a lot of people from the deep darknet, anon, frog twitter and cipher punks and bitorrent communities. (really should be listed as two seperate groups). And people from the Russian darknet community. We have like eight Ivans. (edited)
I see Skycoin as essentially replacing TCP/IP and providing mesh network type functionality at the hardware level, Ark would run on top of it as a top level application layer.
Yes. The key functionality is two things - connecting to people by public key (networking) - distributing self validating, immutble data peer to peer (transactions, blocks etc... content addressible storage)
And you can build almost anything on those two building blocks. The whole internet will eventually be rewritten on top of those primitives and it will replace many of the existing protocols.
arc-over-water Who is the entity that is funding this? I think you have done 2 ICOs? How much did you receive? The first was 10c and the second was @ 50c per coin, released 6 million, is that correct?
samuelvihollandia Are you planning to enter a different exchange market soon?
arc-over-water Have you personally been in Sky from the start? What members have? Who allocates the ICO money etc... I hope you understand that decentralization with investment is a two edged sword, we invest in people but we cannot know these people.... So... we question.. (edited)
thrice.pi with all these outside parties that helped to build skycoin and bring it where it is today who are the main core team who will help to keep all these cool features running. Will these outside parties be recruited for the long haul?
synth
Who is the entity that is funding this? I think you have done 2 ICOs? How much did you receive? The first was 10c and the second was @ 50c per coin, released 6 million, is that correct?
The people who funded the project for the first four years, were early bitcoin and deep crypto people; who were unhappy with the fact that Bitcoin and the other alts did not seem concerned about the core issues at all. They gave us over 1200 bitcoin I think, over several years and did not ask for anything in return.
The early Skycoin devs were doing academic research, architecture and new algorithms. Prototyping and simulation. The later stage people were more project managers and doing implementation.
We did four ICOs for small amounts, to fund development and to allow developers working on the project to buy in. The first ICO I remember was at $0.10 per coin and the price now is about $4.00 per coin, so its up ~35x or 40x, but when you consider the Bitcoin price going from $100 to $3000, the increase has not been so much. lol (edited)
arc-over-water With the price up 35x in about 1 year, is it not now time to cool the run up and release another ICO? At what amount of coins released and what procedure?
mike Would Intel Edison or Joule, or Samsung Artik 10 work well as a Skywire wireless node? They have 2 Gb-8 Gb RAM, 8-64 Gg eMMC storage, 802.11n wireless, bluetooth, and some with Zigbee?
synth
Have you personally been in Sky from the start? What members have? Who allocates the ICO money etc... I hope you understand that decentralization with investment is a two edged sword, we invest in people but we cannot know these people.... So... we question.
I think there wer three different groups that merged together in first three years, that had similar objectives. Because the code was in different language. There was python, C code and then eventually golang and the golang code became the basis for the current codebase.
The way the coin allocations work, is that it requires unamimious consent for releasing coins and it has to be for a specific, ear marked purpose and can be blocked by any of the devs.
Then there is a pool of coins in bitcoin for various project managers to allocate. And that is an operational fund for paying developers, contractors, marketing etc. Then different people have different responsibilities.
Then we also have corporate funding and sponsorship and some companies paying our full time devs etc, which helps a lot.
arc-over-water Silicon Valley (TV SHOW) recently had their decentralized web running on a network or refrigerators? So i would guess, smart phones, smart gadgets? Home gadgets etc could add services and receive rewards from Sky?
mike best would be a totally open source and publicly audited manufactured system on a chip for the nodes to prevent any backdoors. Even chip designers now don't really know what they're putting into the chips since they just drag and drop black boxes known as IP cores into the ASIC designs.
synth
With the price up 35x in about 1 year, is it not now time to cool the run up and release another ICO? At what amount of coins released and what procedure?
I think the Skycoin price has been doubling every 40 days, for as long as I can remember. However, it will still be years before it is in the top 20, its still a long way to climb. It took bitcoin years to go from 0 to $1, even though it was growing at 1% per day the whole time for six years.
best would be a totally open source and publicly audited manufactured system on a chip for the nodes to prevent any backdoors.
we are going to use arm
arc-over-water IOTA is also working on their own hardware for nodes etc, Trinary asset is JINN
synth all intel and AMD systems have remote management engine backdoors. So they are not safe for storing large amounts of coins.
We also have alpine linux and special version of linux, that is 6 MB and has everything that is needed for running our toolchain. It will not have any binary blobs in the kernel or anything that we cant compile from source. It does not have systemd and does not have gli, but uses musl. And does not have openssl.
mike so looks like the Samsung Artik 5 and 10 can run it no problem, they're ARM based. 25x35x4mm package for the Artik 10, Artik 5 is smaller, less powerful but has 2 separate antenna ports, nice for mesh networking with an omni and a directional antenna.
earlyarkinvestor how does Ark compare to Lisk?

mike nice! looks like an ARM based server rack
let me know if you need any help with it, see you're on solidworks, which I run as well.
synth this is the skycoin cluster; it has 8 CPU boards; 4 cores per CPU, 2 GB of ram per CPU and 64 bit ARM processor. Only one program will run on each individual board, so there is compartmentalization and a physical gap so that compromising one process on a system does no allow all other processes on the system to be compromised
mike looks like 2 ethernet ports per board.
synth and the hardware does not have the qualcom backdoors and is actually chinese equipment; and the backdoors are normally at the kernel level because they are not at hardware backdoors yet
lol
mike do they have SATA ports, maybe M.2 for storage?
synth and we will hav an ARM openwrt router eventually too
this model does not have SATA, but we have a model with SATA; you could hook up 16 2 TB drives, lol and download half the piratebay to your cluster (edited)
the skycoin infrastructure is cluster based and designed for running across +300 computers, with one "node" deployed per computer. Eithe a CXO storage node, or a skywire SDN/meshnet node, or a VPN end point node or a consensus network, or skycoin node, etc. We have multiple node/application types.
so this is a "personal cloud' by itself
its not like StoreJ where you have other people storing your stuff; you are going to have ~5 clusters and 300 computers and can store your own files, on your own internet, on your own hardware. You do not need to go outside of your own network.
mike Have thought it'd be nice to have a board with an array of M.2 sockets to run SSD arrays without all the cables, have the busses shielded in circuit board.
synth yes, i think there will be m.2 eventually
these actually use a microSSD for storage, and its 48MB/s
mike any idea on the pricing on your ARM boards in quantity? We are looking at Intel for Bitseed V3, but ARM would be good to stay with, especially using your boards if there is SATA.
arc-over-water Do you have a general idea of usable functions to be released next in what order? The first release was the Coin and wallet, then the ICOs and can you give a general future with dates if you can
synth the boards are $30 each and the memory for solid state, is actually more than the the cost of the CPU/RAM/board now. Which is sort of insane.
mike so you have microSSD, what's maximum size? we shipping 1with Tb hard drives right now
synth Bitseed mike is going to help with this; so we can pool the boards and do a custom PCB
mike yes, that's where we see the price jumps, is in RAM and eMMC costs.
and it's hard to find low cost boards with SATA
synth try the orange pi
the price goes up 30% for SATA
mike yes, very nice specs.
synth eventually, we will make one that has custom PCB and is a pluggable blade server, I think.
mike I like the Samsung Artiks for the tiny form factor for drone routers, cubesat/picosat possibilities.
but like the fact that you are controlling much deeper down the supply chain with your boards.
synth we only need ram, CPU, then microSD slot; and that is it. so the wifi and all this other stuff is just crap and its junk. We only have communication, storage and computation. So should be minimialist.

[Build Help] $1500 gamer, multi-screen capability, with some scryptcoin mining/protein folding/video editing on the side

I tried this in /buildapcforme and didn't get any response, but I don't think I need help from scratch since I already have an idea of what I want in terms of parts, so here's a shortened copypaste:
Uses:
Budget: As cheap as possible. I'll go over no more than $2000 if need be for the triple-monitor capability.
Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?
If there's any specific features you want/need from the rig, please list them.
Do you have any specific case preferences such as a window or LEDs, or do you have a preference for low-noise components?

With that build, what are your thoughts on the 2x R9 280x's? I'm having trouble finding comparable benchmarks, other than this which only compares it to lower-scoring GPUs. I see them as providing a fair amount of number crunching capability (aka mining), as well as being still top-of-the-line graphics for gaming. I probably shouldn't concern myself with mining if I can get a better performance out of games with a single GPU for less $.
I've never SLI'd or CF'd and everywhere I see it mentioned, I notice people have problems with it or that it doesn't always work. What should I know about multi-GPU setups?
I notice a lot of budget builds use an AMD CPU. How much can I expect out of the 4770k over a similar AMD cpu like the FX-9590 or 8350 (a much cheaper one), aside from the marginal chance in benchmark scores?
I could save getting a cheaper PSU probably.
I live near a Microcenter. I'm guessing their prices are lower for pickups.
Sorry for the long post. I hope it doesn't scare anyone off! I'm just not going to drop $1,500 without properly educating myself first.
Thanks!

What entity manages .com, .net, .gov, .us, .cn domains?

For the longest time I still have not a clue how this works. I am not sure if this is the right subreddit or something like networking
This is all I understand so far about the web (or internet?), computers, and electronics in general (its super long just skip to bold part if you need to)
INTERNET:
Okay, but who manages the .info, .com, .net, .cn, .rs, and .gov top level domains?
There's obviously some domains that are specific to countries, and are most likely managed by that countries' government entity. E.G (.us for usa? .ws for russia, .cn for china) but aren't nearly as popular as the .net and .com domains.
.Org and .gov are US? government regulated top level domains to my knowledge, where .org is mostly nonprofit. U.S.A uses .gov domains for its government organizations
So I understand that some countries government manages that domain. But what about public top level domains, like .com, .info, .net, .ca?
Who manages the database for those? Who gives authority to godaddy for those domains for rent? Who mediates copyright conflicts for those domains? (E.G. say my name is Mike Cro Soft, and I wanted to rent a domain called mikecrosoft, but get DMCA'd / copyrighted by microsoft.com)
Like, what are the big organizations mediating internet protocols and legislation on a global scale?
Who or what has access to the biggest picture of the web, and its workings and backend?
sorry for the long wall of text, I've been missing some vital information on how the web? (or is it internet?) works
disclaimer: I don't take CS classes and did not major in computer science. So I might be really off in what i understand about the internet as a whole. Most of this is just what I learned from browsing reddit and youtube
Apologies in advance if i butchered a bunch of terms and how things work. I just wrote things as they randomly came to me
