[XMR] Monero - A secure, private, untraceable cryptocurrency

[Drhiggins]

Just asked this on the mining thread but wanted to post here as these pages are viewed a lot more than the mining thread.

Has anyone here ever mined with a Raspberry Pi 2 Model B?    If so which mining software did you use or is there any support for mining with R-Pi?

Then I got to thinking is mining possible with multiple Pi's running in tandem.  So I'm wondering if mining can be done by linking the R-Pi's together with a program like Putty?

Any thoughts, links appreciated.

I just bought a R-Pi with a small case and 3.5" LCD that you mount to the case.  Setting up another Node with it as soon as it comes in.

I'm not understanding how you would link them together with Putty.  Putty is just an SSH/Telnet/etc client.  It's not something like OpenMPI or clustering software.

Pi's don't have integrated AES, so the hash rate is going to be abysmal.  Absolutely not worth it in any way.

But let's pretend...

Let's say you had 5000 of them, power is free, and Wolf's modified (non-AES) CPU miner would run within the memory constraints of a Pi.  I'd probably do a (i)PXE boot with a standardized image and build one server as a pool.  You'd get pseudo-linking/clustering via the pool.

So I was dicking around with the source code to try to visualize what some of the data created in generate_keys function looks like when running ./simplewallet, and I get this for the supposed SECRET_KEY:

(sorry the output is garbled, not sure why other than the wout function I'm using is looking for a \n character)

There appears to be 3 different times when generate_keys (in /src/crypto/crypto.cpp) gets called while running ./simplewallet

Yes at the end of outputting each index of "sec" there is a "endl" for new line. Not sure why the output is all jacked up.

Any input or tips would be helpful. (I'm finding that there are a ton of programming concepts I'm having to revisit while reading the source  )

Round #1 after running simplewallet (create secret_spend_key?)
"sec" is initialized as "" empty



Round #2 after running simple wallet (create view_key?)



Round #3 after running simple wallet (not sure why it gets run a 3rd time???)



Here is the code I was adding output statements to (I used wcout instead of cout as I was getting even more garbage characters with cout):

Code:

secret_key crypto_ops::generate_keys(public_key &pub, secret_key &sec, const secret_key& recovery_key, bool recover) {
    lock_guard<mutex> lock(random_lock);
    ge_p3 point;								

    secret_key rng;

	//output sec #1							

    if (recover)
    {
      rng = recovery_key;
    }
    else
    {
      random_scalar(rng);								
    }
    sec = rng;
	//output sec #2	
	
    sc_reduce32(&sec);
	//output sec #3	

    ge_scalarmult_base(&point, &sec);	
	//output sec #4	
							
    ge_p3_tobytes(&pub, &point);									

    return rng;
  }

My noob ass knows enough to sound stupid, thanks for the enlightenment    I'm just looking for ways to improve mining and do a little weekend tinkering while I have some time.  I am looking forward to the Wolf AMD GPU miner.  My 280x's could be pulling more especially after seeing some screen shots of some beta testers that have run it.  

For now I will just tinker with setting up my R-Pi as another node help the network out.

Well the strategy should be presence in south america, so we would need a native translation to esperanto

Huh... maybe Spanish would be more useful than Esperanto? 

Portuguese and spanish if you want to cover the southern continent of america 

i thought someone did do a portugese translation .....

This was adapted from a previous one that was outdated. We just need more content to attract the brazucas

<- That guy volunteered for the PT translation, atm just waiting for the multi-language backend to be ready.

i'l volunteering for a dutch translation and an attempt at a translation to Esperanto

backend would be useful... We could use transifix or something like that.

Transifex was suggested a long time ago. Read fluffypony comments about jekyll to understand some reasons for the delay. Many people have plans that are on hold now until next tagged release and website translations.

anyone have any testnet XMR they can donate/send to me?

Just do start_mining? The testnet difficulty must be pretty low so you'll get blocks within a few minutes I'd guess. You'll have to wait for them to mature though.

that's what I planned on doing but in the interest of saving time (not sure how many i wanted to mine) as I was waiting for the blockchain to download/sync i'd ask any testnet millionaires

Quite funny, i noticed that i am a Senior Member by now and secondly i just found out that i am the only full node in my country  
Both findings make me kind of proud yeeeaaahhhhh  

reminded by that graph that there's no presence in south america.

Well that's kind of sad if you take in consideration the naming of MONERO. Maybe we should host a VPS there....

based on that map,

shhhhhhh


don't tell the chinese en masse about Monero ....yet.

New Zealand, India, Spain, and Mexico need some Monero love. Others too of course, but those were obvious to me.

I'm not sure how accurate that map is. I have been running a full node in Italy now for a little more than a month and it has yet to show on the map.
(yes, it's working, > 30 INC connections)

[tankist0]

I'd like to announce a product request, something like http://bitseed.org/product/core/

Instead of running Monero node on a home PC or VPS, I would prefer a dedicated router-sized device, which consumes less power and has no additional overhead. With built-in updates management, i2p capability and equipped with SSD - that's what I'm looking for )) Hardware developers, can U here that?

Could you check your node's IP on this site https://www.iplocation.net/ and tell me which country it reports for "Geolocation data from MaxMind" (the last one from the list) ?

Thanks!

and how much would you be willing to pay?

how much would you be willing to pay if it could also mine (~200 or 250 or 500 h/s)?

how much would you be willing to pay if it could mine and also ran the pool software (so, you'd have your own private pool)?

how much would u pay if it could run additional decentralized software?

and why ssd?

Run a node on a Raspberry Pi. It's way more inexpensive than the device you linked to. You can get even get external storage for it.
