121  Alternate cryptocurrencies / Altcoin Discussion / Proof of work based on human energy only on: November 23, 2013, 12:39:24 PM
I've been thinking about this a alot...but does anyone have any conceptual ideas on how to create a coin that is only mineable by human energy?

I think such an alt coin would be more revolutionary than bitcoin, money is directly linked to the physicality of any individual...would this not make society more democratic if such a coin took off?

I know it's a crazy showerthought idea, but just curious as to the feasibility of such a thing?

I have a guy that wants to mine 1000s of these things a day. Cost and electricity is not an issue at all...

I think it impossible. There are only about 14k XPMs available to be mined a day. You need serious mining power to get "1000s of these things a day". Are you sure he has so much funds and electricity to get.. say 10% of the network? BTW, if that would happen he would raise difficulty.

Interesting. I will let him know that. I don't think he's really concerned about money or power, but I don't think we should be taking 10% of the network power. I'm thinking a 1-2% is where we want to be.

If this is Intel Core 2 duo E6300 1.86ghz, than you will receive ~7-9 XPM/day from 50 CPU's.
There is no mining calculator for XPM. This estimate come from my personal statistics. I mine here: http://ypool.net

Ok, and if I wanted to maximize the abount of xpm/day a single CPU could produce, what sortof core processors should I be looking at? I7s?

I have a guy that wants to mine 1000s of these things a day. Cost and electricity is not an issue at all...I just need to give him some ballpark hardware stats.

So I have a guy that wants me to setup a mining rig for primecoin on 50 cpus in his office (he owns the place)

I'm pretty sure they are just basic computers, would it make more sense to join a pool still or just solo mine on all of them?


50 "Office" CPU's give him only ~5-10 XPM a day. Even if the electricity is free -  it's not worth it.

How did you come up with these numbers? Basically I have a guy that want to setup an operation that mines 1000 xpms a day and he's asking me what he needs to buy to get it setup.
Because I know how much is the profit TODAY from usual office computers. If you tell me what exactly processors installed, I will say the exact number of XPM/day.

They are Dual core 1.86ghz cpus, can you also explain how you come up with that estimate?

Im pretty sure pool is better, if you connect only to slow clients, you may get higher stale ratio, worse than paying pool fee

How can I determine my expected prime generation from my primes per second number?

Assuming I have dual core 1.86ghz cpus?

I hear nuts...but I don't see nuts  Huh In fact I see legumes. T_T You could probably do something similar with Hazelnuts.

Either way, they are spicy and delicious Smiley

+1 

this post made me giggle and get hungry--creative thinking on marketing and sales too.

Good job.

Thanks, and I would ship anywhere for the same price if it weren't for the hassle of filling out custom papers.

Haha, you still around moki. Just found this on your website...

http://www.mokimarket.com/auction_details/2124

Haha google some more and you will see I sold the site so not sure what that's about. I ran the site for 2 years with 1000s of positive feedback ratings.

Zimnuts is the first commodity that can only be purchased with Primecoin!!!

My homemade nuts are soaked in a mixture of 6 million scoville hot sauce, honey, cinnamon, and sugar; they will pleasantly please and torture your taste buds. Just follow this simple 2-step process to get your own batch:

Step 1: Text 5617406393 with your address (US and Canada addresses only)
Step 2: Send 10.xxxx Primecoin to AKEC8oNDdR3TzmnmmFk1pk67N5NVtqC7u5

The .xxxx amount should be last four digits of phone number you texted from, So if your phone number is 555-555-2357, you would send 10.2357 Primecoin.

Peanuts will be shipped within 24 hours of payment.

Heres how to mine primecoin in a few simple steps

1. Download the precompiled binaries or do a git clone and compile your own executables like how would be done to litecoin.

2 visit the appdata folder
Windows: press the windows key and R. After this type %appdata% and make a folder called primecoin. In this folder create the primecoin.conf file shown below.

Linux: visit the users home folder and press control and h to show hidden files. create a folder called primecoin and create primecoin.conf in that folder

primecoin.conf file
rpcuser=****username***
rpcpassword=****password***
rpcport=***any port(mine is 8001)****
gen=1


I created the primcoin.conf file in my primecoin folder (Just pasted stuff into notepad and saved in already existing primecoin folder from wallet installation).

Not sure what to put for rpcuser and rpc password. Also Not sure what to do after file is created.

I'm a complete novice at mining so any additional steps would be helpful.
user/pass for most users doesn't mean much, you can put whatever you want there. It's just if you use a program like cgminer, that's what info you put it. There's no external miners right now, so it doesn't matter much right now. Just put fill it in with whatever.

Once it's saved, this is the file that your client uses for its settings. Just start up your client and it will now mine (because of the gen=1 line in the .conf), that's it!
HOw can I tell if it's working?

I wouldn't go that far.

I know not yet. But I would like to see a proof of work linked to something like finding new primes and this project is the closest I've seen.
140  Alternate cryptocurrencies / Altcoin Discussion / Re: [XPM] [ANN] Primecoin Prerelease Announcement - Introducing Prime Proof-of-Work on: July 03, 2013, 06:57:33 PM
for a POW algorithm to be useful for blockchain verification it must be

 - hard to derive (for transaction verifiers)
 - controllable difficulty (so as more nodes are added, the difficulty can rise)
 - easy to prove (for relaying nodes)

hash algorithms are good here.  An algorithm with primes sounds like it would be based around the factorising problem (e.g. as used in RSA) - but the question is how Sunny has designed it to be variable - perhaps the difficulty is set by the length of required prime in bits, and the POW is two primes and a factor that meet the difficulty.  This would be very very ASICable compared with scrypt, but I don't think any off the shelf ASIC cores would exist (unlike with SHA256)

Interested to see what Sunny has come up with here.

Will

Here is something which might work. It is based on Pratt certificates (see http://en.wikipedia.org/wiki/Pratt_certificate).

Mining process
The miner attempts to find a large prime n which has the following properties:
  • The most significant 256 bits are equal to the merkle root
  • The prime is large enough to meet the difficulty target
The miner can do this by trying random large integers (the least significant bits are the "nonce") and running many iterations of the Miller-Rabin test. With enough Miller-Rabin iterations, the miner can be quite confident that they actually have a prime.

Proof of work
To generate the proof of work, the miner generates a Pratt certificate for their large prime n. Generation of a Pratt certificate is very hard; it requires the factorisation of n - 1, which is requires exponential time in the size of n. Yet it is easy to verify a Pratt certificate; verification is polynomial time in the size of n. For example, factorisation of a 1024 bit integer is about 7 million times as difficult as a 512 bit integer (according to http://en.wikipedia.org/wiki/General_number_field_sieve), yet it is only 16 times as difficult to verify.

This meets the criteria for a useful proof-of-work: hard to generate, easy to verify, adjustable difficulty and incorporates the merkle root.

Mining pools are more complicated to implement, since integer factorisation is not as trivially parallellisable as hashcash. This might explain why the initial client is solo-mine only.

It also has the property of being sensitive to improvements in factorisation algorithms. This makes it somewhat resistant to ASICs, since algorithm improvements may invalidate ASIC designs, so ASIC developers may not wish to take on the risk.

(Edit: linear -> polynomial)

I'm very excited about this coin. Finally something that will actually have real value.
