Stripdown of a Bitmain Antminer T9+ cryptocurrency mining rig. This monster can calculate 10.5 trillion SHA-256 hashes per second. I thought it would make a nice shed heater (with cashback).
I'm working on repairing S9 hashboards and see from this video that there is a strong similarity to the T9+ boards. Along the way, I've learned alot about the ASICs and boards so may be I can add some color to the commentary in this video. The T9+ has 54 asics per board for a total of 162 asics. To get the total hashrate, you need to multiply the number of asics (162) by a) the clock frequency used to drive the chips and b) the number of parallel SHA-256 hashing circuits inside each chip. Apparently, each SHA-256 circuit is able to output 1 hash for each clock cycle. I don't know the clock frequency or number of parallel circuits in the T9 asics but for the S9 with 192 total asics, operating at 13.5 TH/sec with a clock frequency of 625 MHz, you can back-calculate the number of parallel circuits within each asic as about 112. I'd bet that the T9 asics aren't all that dissimilar to the S9 asics - different generations of the same theme.
The controller communicates with the asics, the pic and likely a temperature sensing chip via a serial bus which is at least similar to I2C if not the same as. The pic may have its own serial bus. It looks like the T9+ may use 3 serial busses for each board - not sure, the S9 uses 1. Because there are so many chips, the communication signals are connected to the asics in daisy-chain fashion. The likely reason for this is to keep the electrical load on the serial bus within reason. The controller's serial bus signals are directly connected only to the first asic. The first asic then (apparently) contains a driver circuit that passes the serial bus signals to the next chip in the chain and so on for each successive asic. With this arrangement, the controller only sees the load of 1 asic on its serial bus and each asic also sees the load of 1 asic (the next in the chain) on its serial I/O pins.
Since each asic depends on I/O signals from another asic immediately "upstream" or "downstream" in the chain, any asic in the "chain" that fails prevents other chips that are further down the chain from being able to communicate with the controller. So, if the monitoring software built into the miner reports that it found 37 asics whereas 54 are physically installed, most likely what is happening is that chip #38 has failed and is therefore unable to pass the communication signals further down the chain thus isolating and incapacitating those asics. The chips past #38 are probably good (no guarantees since they can't be tested) but the control board can't determine that because it cannot communicate with those chips. The remedy in that situation is to replace #38.
In the S9, and I suspect also in the T9+, there is an I2C based temperature sensing chip. That chip is able to connect to 2 temperature sensors. The "sensor" is or can be a special type of transistor that has a known temperature profile vs. voltage, resistance or current. One sensor of this type is built into the temperature sensing chip. This sensor measurement roughly reflects the "board" temperature. Each asic also has one of these special transistors built in to be used as a temperature sensor. However, only the sensor in the last asic in the chain is connected to the temperature sensing chip. This sensor reflects the "chip" temperature but keep in mind it represents only the chip at the end of the chain. The asics upstream "should" be operating a little cooler since they are getting cooler air - the air warms as it progresses down the chain. If an asic in the middle of the chain fails and thereby prevents communication with everything further along the chain, then the temperature measurements also become unavailable. Without a temperature measurement, the software cannot properly modulate the speed of the fans so they just go to 100% when there is no temperature measurement - the only safe option other than shutting down the whole chain.
The voltage regulation circuit with the 4 mosfets mentioned in the video steps the voltage down from 12 volts to about 9 V on the S9 - probably a little lower on the T9+. This 9V is then divided up by additional voltage regulators that are closer to the chips - in series fashion. In the S9, there is an LDO voltage regulator for each group of 3 asics and as there are 21 groups of 3, each group gets about 9/21 = 0.425 V to feed the power hungry portions of the asics. The PIC controller outputs a signal that inhibits/enables the dc-dc converter, another signal that allows for slight adjustment of the dc-dc converter output voltage and also a clock signal that determines the clock frequency used by the asics. So, overclocking and undervolting are possible with the right software access since the PIC is able to adjust the voltage and frequency.
There are a variety of problems that crop up with hashboards. With so many asics, the probability of an asic failing is arguably the most likely thing to happen. The mosfets can also fail and there are several capacitors that may present weak links. A problem I"m perplexed has to do with one of the communication signals named BO. It is a signal that indicates an asic is "busy" communicating with the controller - to avoid bus contention. Normally, this signal should be logic low but on some of my boards it is continuously logic high thereby preventing communication - so the monitoring software reports that it finds 0 asics. If anyone has any insight on that matter, please leave a comment here. I've not been able to find any information about that issue anywhere.
Hi Rodney, is there an email I may reach you at? I'm an EE looking into repairing S9 hashboards like yourself, looking for some guidance, etc.
This is the only useful information I've found on the internet about these devices! I'd also be interested in contacting you directly. I've taken an interest in the devices and simply want to explore the engineering aspects of them!
such useful info
Can you use an s9 board, pair it with an s19 control board and reprogram the pic to essentially turn it into an s19?
No. The speed of the machine is limited by the asics on the hashboards. The pic is able to adjust the clock speed and therefore the Hashrate but there is an upper limit for the clock speed at which the S9 hashboards can operate and the pic in the S9 can already reach that max rate. I don’t know for sure but it is possible that the s19 clock speed is similar to that if the S9 and that the s19 achieves its higher Hashrate by having more parallel circuits within each asic. In reality, the s19 is likely faster for both reasons - higher clock rate and more parallel circuits since it is based on a smaller size for the internal circuits. Smaller circuits take up less space so you can fit more circuits on the same size chip and they also create a shorter path for signals to traverse so that it takes less time - and can therefore be operated at a higher clock speed.
The huge chip behind the ethernet port is actually very interesting. Many motherboards have it. There is no silicon inside. It's just full of tiny transformers.
I suggest using a load of isopropanol and a suitable brush of some kind on that board and give it a real good clean. You might be lucky and removing that corrosion and crud might bring it back to life.
I have had boards with water contamination and dead in the past, sluiced them off with warm water and a toothbrush and dried well and they have come to life,nothing to lose.
I'm impatient to see the next video with the repair attempt :)
Where is the beef?
That power supply looks beefy. Let's take a peek inside shall we?
Well, at least you have 324 Raspberry Pi heat sinks you can resell... :-)
TBH, I was more interested in the PSU which you didn't show :)
I had mine in my shed too till one hot day in the summer fried it. I had it running off a battery bank with 1.5KV of solar and 800watt wind turbine powering the bank of batteries and it still used to run down the batteries.
You bought them for spares? For spares for WHAT?? - Oh, heater with cashback, fair enough.
A lot of the retro PC guys; Thoroughly wash with warm soapy water, then de-ionised water; then Isoprop to wash away any residue. Some contact clean may also help.
Your mileage may well vary :)
I too thought there might be just some conductive dust somewhere it doesn't belong (or a bad connection because of corrosion....)
Considering its newer more resilient hardware you could also use brake cleaner at least that's what a lot of people use to clean GPUs nowadays
Simple reason why this (and other) Antminers have water damage.
People running these wanted maximum profit, so would put the unit right next to an aircon. Being that close would result in water getting blown or dripping into the electronics.
Greta would have a stroke....
how dare you
@@gertrummo9007 Indeed, she's a child.
I recently found out myself, those aren't PCIE connectors. PCIE connectors are for video cards or similar devices. The ones use on the motherboard are referred to as EPS-12V. They do have different pinouts. I came across this issue when I needed to add an 8pin PCIE connector and thought I could use the CPU/Motherboard connector. Nope.
New business model: buy up stocks of old useless bitcoin miners and convert them into "smart network connected" room heaters. Just be a bit vague about why they connect to the internet ;P
Converting SHA-256 into heat!
I remember a company installing servers into people's homes as heaters, I think in one of the Nordic countries
Qarnot already do this with their "crypto heater".
Using Bitcoin as heater, might be the only way of keeping Bitcoin ecosystem honest, mainstream adoption will most likely happen when Bitcoin ASIC design start to reaches its plateau.
Fascinating, I’ve always wondered what an ASICS mining rig was like
Charlie Barker it really looks beautiful. Thinking of starting a farm of my own too...
Heating the shed instead of fixing the shed is insanity, even with some cashback.
God, I hate those laser marked ICs. Most ICs used to be easy to read before the manufactures changed from ink/paint to lasers to save 0.000001 cents per IC. Really annoying especially if they are expensive ICs to begin with.
People put them by the air conditioner and they get wet and the traces disappear from corrosion
I have a Dell PowerEdge Server in my shed running ESX and all my VM's. Its a great shed heater. The bonus is the server is kept cool. With the exception of the summer when it gets a tad toasty. Last yr it was about 40c in my shed but the Dell was coping ok, fans running flat out.
I get over 40C without a thing running. :D
Incredible. There's a whole sub industry churning out ever faster hardware so the extortionists and money launderers can have an easy life.
I suppose it beats getting a real job.
You might just try zero residue contact cleaner and a tooth brush, on the corroded parts, then let it dry, you never know it might just work, those I wouldn't hold my breath.
This is going to be a popular video!
That would be nice :)
Knew i had a reason to subscribe years back! love your videos
I guess the person that owned this thing shoved it in front of an airconditioner while operating. This isn't the first one of these I've seen killed from water damage.
likely condensation
It looked like the liquid damage is worse than you think
While you were rotating the board you could see it just below the antminer logo running’s over to the fpga and down to the connectors with the black pins
I heated my apartment with 2 s-9s back in 2018😂😂
12V@100A=1200W
you don't need that power to keep a bit of damp away, specially if you vent the shed as i suggested, couple of hundred watts max on a thermostat so it's not on constantly.
There are lower power crypto miners on eBay - I'd still quite like a working one :)
Heater with cashback 🤣👍
+ Annoying sound
You can do the 9 times table on your hands!
Hold both hands in front, fingers up. If doing 9*6, then bends the sixth finger from the left (including thumb). Count the number of fingers still up, from the left to the bend (5) and then from the right (4). ...54! Ta dah!
Never learned that in school though lol
or you could just multiply 6*10 and subtract 6 without using your fingers like a six year old :)
@@rasz you spoiled my fun!
Every time I try to show someone this they just aren't interested. Can't help some people.
Oil filled radiator isn't as cool, but more efficient and you could probably find a 12v one for less money. Sorry to be boringly practical. Very interesting to see what was inside this tho.
Back when you could make money relatively easily I used mine in place of my storage heaters. Using the economy 7 electricity.
Didn't know that was still a thing.
Economy 7? If you only have electricity for heating and your boiler it would be stupidly expensive to not have dual rate electricity.
@@sh4dowchas3r Don't think I've seen an electric storage heater since the early 00's, is electric only heating still common?
@@uK8cvPAq well we didn't have gas to the flats so storage heaters were the most economical. Given dual rates are still a thing I guess they are reasonably common. I know you can get "wet electric" and fancier storage heaters than we had. Anyway I've moved somewhere with gas now
I have thought about heating my house with miners. In the summer when there is no need for heating, I could use excess energy from solar panels to run them for free and just blow the heat out.
:-D I love your idea for a shed heater :-) Few years ago I had the same one. Works great, practically you are heating your whatever space for next to nothing.
At this point why not collect some americium from smoke detectors, pile it up and use that as a heat source?
Good idea but when the Fans run up you will not Stay near this annoying little thing to enjoy the generated heat. Just saying 🤐
Place it in another place and pipe the heat 😁
@@97Giorgos97 i think thats the reason of the 3d printed Adaptor thing on the Fan.
LOL... just got a bitcoin ad! I never got those until your video, Julian... 8-P
They had it in front of a AC unit i bet.
9x1 to 9x9 is easy. The sum of the two numbers always equals 9 ([9x2 = 18, 1+8 = 9], [9×7= 63, 6+3 = 9]). The next thing to remember is that the tens place of the product is always 1 less then that which is being multiplied by 9. So you look at the number being multiplied, minus 1 from it to determine the tens place, then figure out what is needed to add to that number to make it equal 9 and that's your ones place.
Or.... you could just remember 9 * 6 is 54, because you learned it as a kid. :)
Twotone Or just look down at your ten fingers, subtract your sixth finger and you have “5 4 = 54”, many different ways to get there depending upon what one was taught growing up. But memorization is the most efficient.
Oh, that's a nice one :D
Hilarious... Shed heater with payback !!!
also ... If I had free electricity I would just sell the electricity ... -.-
right now at the moment if i pay myself for the electricity and the bill what comes with the miner i'll have the free electricity. i can use them as a heaters too. i need to get fast those antminers s9's next month lol. i was offered 2 without any shipping costs from miners site great huh? and those machines will be worth 500 without the shipping costs. i can pay mama the rent at the same time and electricity and lol well annoy my Neighbours sit around and play comp games, maybe new comp too lol
1400w at 12v... Sounds like the consumption of a boat 12v to mains inverter.. or a small plasma cutter. easy stuff ;) So did you fix the controller?
I swear your God sent keep up the great work ...at the rate your going i swear its inevitable that your a future billionaire
Julian, thou shall check voltages!
And short circuits. Dont just give up!
I would like to take another look at the controller board - another crypto video coming soon :)
Servers should be in the form factor of electric baseboard heaters. The wall mounted thermostat would just control start-up and shut-down, with someone managing the bids for server time. They'll need an Ethernet connection, or just WiFi. In the northern hemisphere winter, the residents of South Georgia will be well and truly warm and toasty.
Hurray, splendid. I was a bit concerned when I could not find the hardware specs of this setup online. And it got me quite curious.
The new KD5 miners sell for around 40000$.
I am wondering now; how about connecting up these miners and using the extracted heat to power a generator of sort, perhaps a stirling engine, feeding the energy back into the system. That might make them more efficient as such.
Again, thank you for the investment and share.
Highest regards,
Mac
That won't work, conservation of energy is a thing in this universe.
@@RobinCernyMitSuffix That's the whole idea.
Instead of just letting the Hot air out and cool down. Recycle it by converting the heat back into energy.
That's real conservation of energy.
I wan't talking about a perpetum mobile.
50 quid is a pretty good price for spare stuff. The PSU and cables are already worth it. Plus a heatsink, high speed fan, and control board could be reprogrammed to do anything else you want, but have a lot of GPIOs and serial IO for some weird projects, like controlling LED matrices for example or measurements and data logging. If the PSU is poor quality, or control board is dead, then it is so so deal. But if you need a lot of good quality heatsinks it could be an option.
Plus, any new SHA256 currency, you could hop on, mine a week, sell it all for quid and potentially pay tne power bill
If this is aimed at drying the damp shed, you could add a few cheapy peltier modules, and a water channel. they are pretty gud at dehumidifying. I would look at solar power, but then I live in Australia, we see a lil moar sun than your shed will
also, that's a dual-core arm chip too. You could conceivably repurpose it into a small computer
You might reverse engineering this FPGA board.It will be handy for other projects. The SOCs are powerful really.
From a diesel-heater to a crypto-heater... Looking forward to see you run this with an Arduino...
Is there any possibility to use a hashing board like this in connection with another antminer running a different algorithm? E.g. a x3 or something like that? Because I was wondering where the algorith is located on that thing (I thought it would be just on the control board)... Any ideas?
they are purpose built for one specific algorithm if you run a different one it may be worse or doesnt even work.
those chips can do only one specific thing (mining) nothing else
ASIC nudity in the morning. What's not to like. Thanks for the video.
This one has done it. We really need to pitch in together and get Julian somewhere warmer and sun shiny..
Yes please :)
Looks like you are set for smallish heat sinks for a while. Just pop 'em off and give them a good cleaning outside. Now what to use them for?
Raspberry Pi coolers...
My GPU heats my entire office, as it's only about 5m2
Ya daft old sod !....keep it up.
Does this mean 5amps at 240?
Or does it not take 240
They are only good as shed / greenhouse heaters, the noise they generate is enough to drive a crazy person sane lol... I use GPU's to mine alt coins as my solar system dump load, effectively turning the sun into money. :)
I'm surprised we still have to put up with this mining plague
Agreed. Powering mining systems by renewable energy is one thing. But what about all those places in the world that mainly use coal / oil / gas, for power. Really makes you wonder how much pollution has been caused by mining.
@@HakoFrost I'd gladly burn rubber and crank the diesel pump to eleven only to annoy environmentalists. :P
I used to run a hobby-scale mining system. Completely impractical, as I used cheap dated hardware - it was intended to learn the tech, not to turn a profit. I rewired it a little so I could use it as a solar dump load - when the batteries on my experimental solar setup were full, it would burn off the excess power making me some litecoin.
I still have the litecoin. It's not worth much.
@@HakoFrost There's a long complex discussion that boils down to "Yes. But VISA has to expend computing power maintaining their communication network too ... and this can be shown to scale to needing less 'waste heat' per transaction." On the one hand, it's just a box spinning wheels, on the other hand it's "securing a network" .... VISA spends nearly half of the 3%-of-everything on "infrastructure".
@@shrikedecil I've always wondered about that. ATMs, terminals etc etc must use a fair amount of power. Not to mention the secure servers and all that. Given how they up the encryption I can't say I mind it (it is for a good reason) but one has to wonder what happens once computers can't go faster. It's easy to add more threads / computers for bruteforcing but it's hard to multithread a single encryption since every step has to wait for the completion of prior steps. -Feature size can't go much smaller, IPC / core has stood still for years and this stupid core race where they slap on more cores has pretty much reached its limit too. We're very near the feasible limit of what can be achieved with silicon tech
you should just put it in the dishwasher to see if you can clean up all the corrosion. you cant stuff it up even more than what it is.
i would say use brake cleaner instead. its used commonly to remove corrosion and caked-on dust in electronics
@@shadowxxe it can stuff some plastic tho
The Zynq FPGA and the ram are probably expensive to buy on their own, that with the 300 heatsinks probably makes up the £50 it cost you, I think you made a profit just in parts, also with a free power supply?
You do have free electricity !?? What are all those solar panels !? Put all your surplus solar energy to good use, heat the shed and make money !! Triple whammy !! 🤣🌞
Unfortunately even with his solar panels, he'd still lose money.
There ain't much capacity in those batteries he has. I have a single battery and 180w panel and it can't even run a pond pump.
Now if he had roof panels...!
I think a heat pump or dehumidifier would be a better bet with your $$$...
Louis Rossmann might be able to repair the water damage.
I think there's a video of Louis looking at one of these that was damaged in essentially the same way.
not sure louis' expertise is in ASICs
could you run this bitmain miner directly off of a battery bank with a range of voltage at 12-16vdc?
Hi. Are you share that this t9+ hashboard has 54 ASICS on each side? I thought it was 54 ASICS PER hashboard, but again what's the other side for?
10.5TH in the box, 64.8GH per ASIC. In 10 mins. Means 17.5GH / sec which is quite quick even for an ASIC. So my guess is that each ASIC is loaded with the start and runs like shit, multiple calculators in parallel (as many as will fit in) to get an answer, send them all back to the controller which then tests for a hit. If there is one, fills out the complete packet and sends it back into the pool. So this is the question: will a standard LCA (ie not a Zinc) have enough CLBs to make a sensible calculator for a sensible power consumption for your room heater ? ;)
Interesting. I did not remember there were dedicated mining units, I just saw some crazy videos using lots of graphics cards to do the mining.
EDIT: And it is a nice idea to do the heating with a miner, indeed if you can get it to work again!
They had to quit doing that a few years back, even the graphics cards couldn't keep up at a certain point.
That's one of the weirdest schemes you've come up with in a while.
Thanks - compliment appreciated :)
This is how they do Bitcoin mining in Siberia.

@@JulianIlett I know it annoys some of the viewers but I like seeing people use technology in ways it was never intended for.
I mean, that's what experimentation is.
why not just put a 1.5kW fan heater in the shed? £9.99
Because this is technical Art my good fellow.
Lol. According to my quantum computer
6 x 9 x 3 = 162.
what's inside a bitcoin? a board with a microprocessor wrapped with a bronze cover?
Basic trouble shooting called for. Do you have power YES or NO. Assume the Processors are 3.3v based and proceed. Lower Voltage results in LOWER Clock speeds. I would assume they are 5V operations. Run it as a heater chooching Bit Coins on Solar. Surely you can produce 500W of solar ? Chooching during the daylight hours doing it's thing.
6 x 9 x 3 = 162 so no that is 9 short of 171 they claim. - 17:29
3 per board... hmmmmm.
The case for this would be perfect for a DIY Programmable load.
Will the shed heater be solar powered?
Question: Of all the watts that are used by a miner, do you know how much each component/board/fan uses?
Great teardown video, Thanks.
The hashing chips use almost all of it - the fans use about 25W I think - the controller board uses very little.
Rams? uh, RAM stands for Random Access Memory
LOL I would buy one for all the fun components! I already have some big beefy server power supplies. too bad I dont live in a cold climate!
If only you knew someone who had a 12V solar panel array which had spare power now and then after it had finished charging batteries... *scratches chin*
It needn't power all the chips, shouldn't be difficult to selectively disconnect them. Or, as you say, change the clock speed.
54? What insnity is this? Everyone knows that 6 x 9 = 42.
so what is 6 x 10 then?
I don't know. You'd have to ask the mice.
@@NoHandleToSpeakOf 42, of course.
My friend installed few years back mining rigs into his rental properties as heater replacement. They throw tons in heat while burning electricity and generates money. Kind understand your logic behind this. I'm not sure if you willing to heat your shed while mining. At the moment you will earn around 60$ a month in Bitcoin if leave it running but loose in electricity 1.5kw in hour. . They a very loud I wouldn't want to be in same room next to it. Good luck tho
Bitcoin just isn't efficient to mine anymore. That's why I prefer mining altcoins, such as my Swagbucks miner that still makes $15-20/month while using a mere 5W.
great video thank you.
Do you need more the one power.supply with this unit
well 54x3 = 162 not 168 :)
??? 🙄 Better count your fingers again. 54 X 3 = 162. 54 X 2 = 108. If you have an 8 as the last digit and your adding a number with a 4 as the last digit, you can't end up with a number with an 8 as the last digit (4 + 8 = 12)

The chips are only on one side, but you have heatsinks on both sides

@@shadowxxe just for heat dissipation
@@vmailtk5 yeah that's what i meant you want to dissipate that heat so nothing on the PCB melts
@@shadowxxe The PCB with components are ok with temperatures of 105c and much higher when soldering. The heatsinks and airflow from the fans allows the heat to be dissipated so that the chips can work harder
@@vmailtk5 Yeah I know but, old AMD CPUs could reach upwards of 400c before blowing up back when they had no T junction in of course this arent CPUs however considering that they are even more powerful than those old Athlon processors despite being ASICS I'm willing to assume they would do the same so I imagine it can act as some sort of fail-safe in case a heatsink were to drop off, assuming the heatsinks are mounted with thermal pads, it may not be its primary purpose but i don't see why else your would mount a heat sink on both sides.

Good day, for some reason your recently uploaded videos are not displayed first while all other channels have their most recent first. It makes your channel look dead and unused.
I tried mining cryptocurrency with Antminers and Jalapenos, apparently I got into it about a year too late (of course.) What a waste of good electricity.
Remember that drama with butterfly labs being shifty!
i remember Years ago i had something like 300 bitcoin, later i formatted my HDD and lost my key (wallet). years later bitcoin is worth 1000$ each now. i dont regret it, its just if i had knew...
The Hell man!!? actually one Bitcoin is worth over 10000$ now so you would have 3 millions dollars today. And you say no regrets.

@@DonPavardenis i havent checked the price for some time so i dont know the real numbers. back when i lost my wallet they were worth something like 10cents each when i started. i just used an old PIII 1mhz to mine for some time and i switched between bitcoin, protein unfolding and Seti@home for fun. nobody was even thinking about trading them for money and i didnt even heard of a website you could transfer them into cash.
whats the point in worrying about something that happened 10years ago? nobody took this seriously. nobody knew it was going to be worth even 10$ each years later. it was all for fun. the worst is actually people that invested 10,000+++ to buy graphics card and different hardware just as bitcoin jumped only to be all worthless 2months later. i remember buying a 500$ graphics card for 75$ from a guy that was selling his mining stuff. he had like 30 cards, MB, ram and everything. mining wasnt valuable anymore because nvidia came up with a new card that could be used in a way to mine 1000time faster with only one card. the guy coudnt even afford rent anymore.
look today, its impossible to mine and get good money from it since super computers took over.

What's HASHING ??? (Edit: Any real answers? Coz I don't understand what the thing is.)
drugs are bad, mkay
en.wikipedia.org/wiki/Hash_function
lmgtfy.com/?q=what+is+hashing
Hashing algorithms are primarily used to insure message integrity. You want to be sure that a message was not altered or damaged in transit. You might think of them as super fancy checksums or CRCs. You feed the message into the hash algorithm and it spits out a hah key. The algorithms are VERY sensitive to changes. Even the most trivial change in the source message will produce a different key. This is a one-way process. You cannot (in theory) discover the message content by manipulating the hash key. (Analogy: steak into the meat grinder, hamburger out; can't reverse the process.) Example: I have a message that I wish to send you. I feed it to the hashing algorithm. It spits out a key. I send you the message AND the resulting key. Upon receipt you run the message through the same hashing routine. The key generated on your end should match the key that I sent you. If it doesn't match then the message must have somehow changed in transit. There are many such algorithms, like MD4, MD5, SHA1, SHA256, etc.
@@GeorgeWMays Clever stuff then. Thank you for the explanation. :)
50 pounds for zynq board, that is a good deal.
If those where FPGAs those boxes could be really fun....
Those would be too slow for the task, they are proprietary hashing chips, BM1387.
@@resetcoder I know, but if they where FPGAs instead of ASICs there would be a lot of number crunching potential.
@@gudenau Of course, and would be many times more expensive. But sure would be fun to reprogram to use different hashing algorithms. Or anything else.
