Re: Official FutureBit Apollo BTC Software/Image and Support thread
4. When node complete (should take 2-3 days), if I shut down, will Node still be in place (will it update blockchain from where left off).
5. What can we do with Node? Any advantage for newbie or are we just helping the network in the background

Yes, if a node goes down and starts back up, it will sync the blockchain from where it left off.
More nodes are always better to decentralize the Bitcoin network, but I think you should be able to run "Apps" on the controller as well.

None of the software does an auto pay out. That will all be done manually.
If you know what the pool is about and understand how the client works in its original form and how the actual cracking software works in its original form, you can conclude how easy it would be to manipulate work done, i.e. your percentage of work done to receive more than your fair share or flat out take the private key and claim all the BTC for yourself.
Some people have already tested the programs. I can see how many people use a different cracking software to try and run with the client software. But without the version on github, they can run their program all day but receive zero credit because it is "fake" work/not validated. That is because there are 2 fail safes built into the software that detect bad actors and does not give them credit. One on the client side and one on the cracking side. If either are exposed, then the pool is worthless.
If you have ever ran TDs 64 bit pool and actually watch what is going on when your machine is running the program, which by the way, it is also closed course (hmmmm, I wonder why), you can see the vulnerabilities in it. But you have to pay attention...
I will discuss options with NotATether in private to see if their is a viable solution.

Mmmm okay, alright, just make sure you're safe against decompiling / changing parameters (you mentioned changing percentage reports) and recompiling and stuff like that.
Security by obscurity is possible but hard to achieve imho and every non-obscure security mechanism should always be considered if in any way possible
Re: GekkoScience NewPac / Terminus R606 (BM1387) Official Support Thread
Why on earth do so many folks point to Amazon, eBay et al for components? God only knows what quality they are - odds are, not the best...
There are plenty of real component distributors in the world such as Mouser, DigiKey, Newark, etc. that sell top-quality components made by trustworthy manufacturers and sold at a very decent price.
Stuff from Amazon et al are so cheap for a very good reason...
Well that's just a way for me to say that it's available pretty much everywhere, but ofc I always use high quality components myself There are plenty of real component distributors in the world such as Mouser, DigiKey, Newark, etc. that sell top-quality components made by trustworthy manufacturers and sold at a very decent price.

Re: GekkoScience NewPac / Terminus R606 (BM1387) Official Support Thread
EDIT:
I hopefully optimistic. Took it apart for a closer inspection. Tried the USB cable in it and noticed it had some free movement. Also noticed that on the port itself is some sprung tabs which locate on pockets on the cable. I nudged them down a bit and the cable grips really nicely now. Plugged it all back in and shes on her way upto 700m V5 on the first try!! Just keeping my fingers crossed she stays stable now.

It's a regular Micro-USB Port though, right? I think it should be easily replaced with a spare from Amazon and a heatgun by anyone experienced enough. Maybe better as a long-term solution
Just a quick response for now, will discuss more later:
Here is the problem, it has to remain closed source or people running the program could change a few lines of code and steal the bitcoin that everyone in the pool is working hard for. That is the only reason why it is closed source.

Wait, so the client controls the 'payout' or how could one's modification of the client on their side change how other contributors are paid out?
I think it should be possible to code it in a way that the client, which people run, is open source, so e.g. it can be compiled by users themselves and malware for example can be ruled out etc., but the server side software remains closed (similar to when mining with a pool where the pool software is closed and the client software like cgminer is open).
Or are you worried of someone modifying the client and distributing that version so that benefits go to them?
In that case, it should be the same way as when downloading Bitcoin core: you have a GitHub page where people are always pointed to, always recommended not to get it from anywhere else and on the GitHub they can either read and compile the source themselves or download and verify signed binaries that have been compiled for them by you.
Re: Official FutureBit Apollo BTC Software/Image and Support thread
That's perfectly fine, using a 600W bequiet PSU here. (A PSU's efficiency sweet spot is around 50-60%, so consider that for your choice)
Alrighty! I was wanting to get a new PSU for my workstation anyway due to new GPU, so might just take out the modular 550W PSU from it and run the Apollo on it. Then I'll also have headroom for some stick miners or another Apollo etc. in the future.
The cool thing of the Apollo 200W PSU is that it's so compact and passive, but I guess it will still be possible to tuck the whole setup away nicely even with a full size ATX PSU.
Re: Official FutureBit Apollo BTC Software/Image and Support thread
It can run in turbo and is rated for that, but there is little headroom, OCP will kick in at about 210-220 watts.
Next gen PSU will be able to run at ~300 watts.
Next gen PSU will be able to run at ~300 watts.
Great to hear, thanks a lot! In case I want to get something more powerful right away though, regular ATX PSU's come to mind at first. Anything wrong with a single rail Seasonic PSU? I should be able to just connect a PCIe cable to it and use it for the Apollo right?
Re: Official FutureBit Apollo BTC Software/Image and Support thread
Better to not run at 100% of the PSU capacity though. I run turbo but use an off the shelf 500W PSU.
Also correct, yes, maybe FutureBit has more info about the actual rating of their PSU's - maybe the product pages just say 200W but there's a little headroom built in still?
Re: Official FutureBit Apollo BTC Software/Image and Support thread
Do the stock PSUs work with Turbo mode? What has everyone experience been?
They should! Turbo mode is 200W, eco is 125W - the PSU is rated for the full 200W.Is there a thread yet for the "S1/3/5 upgrade kit" that I see in sidehack's signature?
In my head, upgrading these old inefficient bois would be something like getting one for dirt cheap and building a new hashboard to go into it, with new, efficient chips, so the miner developer (GekkoScience) doesn't have to develop and produce the whole shell, cooling assembly, controller & PSU stuff and just has to develop the hashboard & make sure it physically has the same footprint.
Sounds like a very nice idea to me, if that's what you guys are doing / planning to do

Re: Is it possible to solo mine a whole block solely on insane luck?
It doesn't. With lottery, there are just higher chances for the winner to be different each time.
Oh right, correct, thought I missed something there heh, thanks!
Re: Is it possible to solo mine a whole block solely on insane luck?
Yeah, of course! Nothing changes about the average time needed to mine a block at a given hashrate, but it’s certainly possible to get an outlier.
It is also possible to find it after the double amount of that time. We may consider both occasions possible, but their “center” which comes more often than those two, is 4,722,366,482,869. That's the rule.Of course I fully agree
It’s really very similar to lottery, where you’d on average need to play for multiple lifetimes to win it, yet people do win it from time to time.
Hmm, I wouldn't say that it's similar. Each person is allowed to buy as many tickets as they want, but they usually buy less than five and they never buy around half of the total tickets to maximize their chances. In Bitcoin, pools do so and you stand no chance on winning this “lottery” if they pass on you that far.Specifically, three pools at the moment own 45.14% of the hashrate.
The existence of pools doesn’t change your previously mentioned number though does it? Even if theres more hashrate in a bunch of places and its not evenly distributed, the amount is still the same and shouldnt change the chances of solo miners.
Re: Is it possible to solo mine a whole block solely on insane luck?
Of course you could. But, it's not accurate to say that since you found a block after 1 hour of mining, it takes around an hour to accomplish it. The seconds I wrote are the average that you'll need to mine one block. If you mine more than just one block, sum their required time and divide by the total blocks you mined, you'll see that it'll approach the number 4,722,366,482,869.

You are wrong :v. If you dont have to spent money on electricity then its profitable for you :p prove me wrong. People cant make profit because they have to spent huge money every month on electricity
I don’t have to provide you an example calculation, that has already been done. Even when electricity is not free, as long as it’s in the single digit cent range and you got the miner as close to MSRP as possible, it will work out.
I have no idea how people buy miners at MSRP, but if you could get an S19 for 2500$, esp. if you got it at launch time (as early as possible due to difficulty ever increasing), it would have repaid in a few short months.
Re: Is it possible to solo mine a whole block solely on insane luck?
Even if we assume that you generate 1 billion hashes per second, it'll take you around 4,722,366,482,869 seconds to finally solve a block, given that the difficulty remains the same. That's 54,657,019 days. 
That's just statistics though. You could wait for that many days and get nothing or you could indeed get lucky and get a block after 1 hour of mining at 333MH/s with a block eruptor.
Bitcoin is not yet fully payment system like fiat. Bitcoin is high volatile and common people of Afghanistan would not like it. Well devolped countries should choose bitcoin for payments purpose than off course some small countries will also adopt it.
The thing with volatility of BTC is, that many other currencies are also highly volatile.
After the ~20.000$ ATH in Dec. 2017, I remember comparing the falling price to the (at the time) rapidly devaluating Turkish Lira, and unsurprisingly, Turkish people wouldn't have lost anything (I think they were even gaining) when comparing BTC to TRY since they were falling at a similar rate and TRY was crashing even a little harder.
Another example is that central american states often have massive inflation on their local currencies, so they resort to USD or BTC.
Also, the volatility isn't really an issue if you get paid monthly in BTC and use it to pay for expenses, since you roughly "sell" (by buying stuff) at the same time at which you "bought" (got your paycheck). Some months you may even profit off the volatility, e.g. during bull run - get paid on 1st of month and stuff you buy at end of month will be highly discounted for you, basically. Some months you might take a little loss instead if e.g. you got paid on a "price spike" day and the value of the BTC you earned subsequentially falls. But it should even out in the long term really.
My 2 sats: Especially, if you somehow manage to get new miners at MSRP (as I found here: https://www.coinwarz.com/mining/bitcoin/calculator) and have <10ct/kWh electricity price, you should easily make more profit by mining other than holding. For example an S19 Pro for 2,5 grand.
But right now, where they go for up to 4x that price, it's a quite thin line to walk on where it can be slightly more or slightly less profitable than just holding.
Speaking just economically, this seems to be the case simply because 10K for a S19 Pro seems to be the highest still (in specific cases) profitable price - would scalpers price it higher, nobody would buy it, would they ask less, people would resell for ~10K. Simple economics

Right, it uses CUDA. From what I've read, not even experienced programmers have created a reliable "bitcrack" using openCL or openCL coupled with AMD cards. If someone knows of a program that actually works and actually finds keys, I will look into that program to see if we can adapt it for the pool
Gotcha, sounds good! Unfortunately haven't touched GPU programming for a couple years now, let's see if someone with more experience happens to hop into the project ^^
It's got the pinout and a decent description of what everything does. That's pretty much enough.
Hey sidehack - interesting, so you don't have datasheets either, great job re'ing those chips, respect! Just wondering: for the PCB design, did you then measure the pin sizes and spacings manually or did you find a document that I haven't found yet, specifying exact sizes?
