NobleCoin[NOBL] - 8% PoS | 1Yr+ | MARKETPLACE | PAY | GIFT | CHARITIES/MERCHANTS

It appears that trying to CPU mine is putting a beating on my Mac. CPU usage associated with the wallet is about 95%. The fan is constantly turning.
Is there a way to limit this to something like 50%?
Don't want to damage my MacBook Air.

Sorry for off topic since one is asking. Try this miner (more efficient than built-in miner): https://github.com/magi-project/m-cpuminer-legacy-v2 You can compile it on mac os.
Example of solo-mining:

Code:

./minerdlegacy -o http://127.0.0.1:RPC-Port -u USER -p PASS -t thread_numbers -e cpu_efficiency

RPC-Port is the default value or the one you set in conf file. USER and PASS are the rpc username and password, and need to be set in conf.

I don't think that miner is 100% compatible with Noblecoin,   since the performance it reports in benchmark is far higher than the built in wallet's reported performance (My Core I7-3740 reports about 14000 hashes/sec in the Qt wallet,  but the standalone miner reports  about 58000 kh/sec.  Seems unlikely that a few compile time switches can account for such a wide disparity in performance.   20%, 50% speedup, maaaaybe.  410%?   No.  These two mining engines cannot be using the same algorithm.

Yes, it works. We removed many condition checking which occurs rarely as well as tweaking of gmp computation, that made the leap, while we remained the wallet algo the same for reliability. If you'd like to mine, external minerd is highly recommended.

Hello,

I've been reading this: " https://github.com/eagleflies/noblecoin/wiki/Importing-private-keys-from-old-wallet.dat-using---salvagewallet-option " over and over again and I just don't understand the part 5. ... So to begin with, I had a PoW wallet ENCRYPTED on my PC#1 so I downloaded a new PoW wallet without encryption to my PC#2 and sent all my Nobles from my PC#1 to my new wallet on my PC#2 which is not encrypted and everything went fine. Then I back-upped my wallet.dat from the PC#2 PoW wallet and copied that wallet.dat to my PoS wallet roaming folder.

But what I need to do next? Where do I put that "-salvagewallet" command? I tried to start my PoS wallet just by clicking the PoS noblecoin-qt and the program just crashed like I thought and then I added the -salvagewallet command after the noblecoin-qt.exe like this "noblecoin-qt -salvagewallet" and started it but it gave me an error report and crashed.

So where do I put that -salvagewallet command or is there somewhere some salvagewallet.exe which I need to run? Thanks.

The important question is have you sent the money before the switch? IF afterwards it does not matter and money is still in encrypted wallet. Documentation was written before the switch and presented option of transferring money to unencrypted wallet. But now this option does not exist anymore. I have updated docs to present current options.

Yeah, I did it today. I'll try this https://github.com/eagleflies/noblecoin/wiki/Manual-way-of-importing-private-keys when I get home. Will report how it went.

I did import the private key to the PoS wallet, but nothing happened. No funds added to the wallet. Then I tried again and it said "Error adding key to wallet (code -4)" So what's the meaning of that code? I guess I did everything right at the first place and now that I'm trying to repeat it gives me error for that.

edit. It did add the address from my PoW wallet to the PoS wallet's "receive coins" section. There are now two addresses. One is the original PoS wallet address and the other one is the PoW wallet address.

edit2. I deleted my PoS wallet.dat and imported the key again in the console. Again it went through just like in the "https://github.com/eagleflies/noblecoin/wiki/Manual-way-of-importing-private-keys" last picture. But no funds added. Do I have to run something else, like the -salwagewallet? Or has someone somehow already stole my private key? lol

My mistake,  you are right it does work.   Wow,  I am at almost 25% of total hashpower now, according to netmhashps.   I doubt that will last long!

To stake out a configuration file should I do?

[Coretz]

Hello, brand new to noble coin and I'm only lightly familiar with cryptomining in general. I've downloaded NobleCoin and I've attempted mining, but I haven't noticed any deposits so far.

A few questions:

1) I was wondering how best I can mine NOBLs?
2) Should I join a pool, and if so, what are some good pools that still work? I see a lot of dead links.
3) What is scantime?
4) How do I know when I've earned NOBLs thru mining?
5) Does anyone have any cheesecake here?

And if it helps any, my system is an i5-2500K @ 4.2 GHz with a GTX 650Ti BOOST 2GB graphics card.

Thank you all!

1. if under windows just use your wallet. I do not think it makes sense to invest lots of effort into setting up mining etc since our PoW mining will shut down in 3 weeks.
To start mining just type in console

Code:

setgenerate true 1

2. There is no pools AFAIK.
3. scantime?
4. Look at 'Recent transactions' or go to 'Transactions' and see if you mined 1000 coins.
5. Cheesecakes are overrated!

So I've got it as you said, basically I just should leave it an come back in 3ish weeks?

Here's what my mining info says:

13:54:42  getmininginfo 13:54:42  { "blocks" : 537561, "currentblocksize" : 1000, "currentblocktx" : 0, "difficulty" : 29.69000356, "errors" : "", "generate" : true, "genproclimit" : -1, "hashespersec" : 8159, "networkhashps" : 2282875028, "pooledtx" : 0, "testnet" : false }

14:02:01  getmininginfo 14:02:01  { "blocks" : 537564, "currentblocksize" : 1228, "currentblocktx" : 1, "difficulty" : 27.13638260, "errors" : "", "generate" : true, "genproclimit" : -1, "hashespersec" : 8303, "networkhashps" : 2023728128, "pooledtx" : 1, "testnet" : false }

14:05:08  getcheesecake 14:05:08  { cheesecakepersec : 77 }

I can understand I'm getting 8kh/s.

http://i1262.photobucket.com/albums/ii619/Coretz/noblscan_zpsd3iarrvh.jpg

This is what I mean by scantime. Should it be lower, higher, etc? default is 99, I set it at 33 because I read on a blogspot post somewhere that that was recommended; I don't know why tho.

Thanks again!

So I tried mining with the wallet, left it over night and nothing 

Maybe the miner needs to be redone with something better

[mikeymillie]

external miner was working great until I found a block (err.. share):



DEBUG: [3 thread] Found share!
- info about block that was found here,  snipped out--
HTTP resquest failed: The requested URL returned error: 500 Internal Server Error
submit_upstream_work json_rpc_call failed
...retry after 30 seconds


Any idea what's wrong?  Is this just a typical orphaned block or might I have some settings misconfiguration?

I fixed the above,  so no help needed on that.

But I have now another question,  please tell me if I am misunderstanding how stake rewards work -  I remember the Dev estimating in this thread that after the POS switch,  Coin emission should drop from about 7.2 MM NOBL/day under POW,  to about 0.5MM/day under POS-II.   But there seem to be many rapid and huge stake payouts being generated, much much faster than that. 

What's going on?

What you are seeing is the total amount of coin/input that was used to create the POS block. If you click into one of those blocks you will see what Generation + Fees that were the POS reward.

Details for Block #4395

Value Out: 1,000,208.60839707 NOBL

Generation + Fees  106.19839716

So the above block 4395 used 1,000,208.60839707 NOBL and got 106.19839716  as their POS reward.

[mikeymillie]

Thanks, that clears it up nicely!

It's confusing to see POW and POS rewards in the same format in that block explorer's history list, when they are really indicating very different things.

in this situation reward percent per stake (probable per day) is just 0.01%. Is this real percent?

[TimC]

https://github.com/eagleflies/noblecoin/blob/eagle/src/main.h#L39

https://github.com/eagleflies/noblecoin/blob/eagle/src/main.cpp#L948

It is 8% annual rate and the source code also shows 8% rate.

[fairglu]

That column does not display rewards but total amount of coins transferred in a block. It will match reward only for a PoW block where you have no user transactions (only the coingen transaction).

[morphtrust]

once again we are seeing why I always say craptsy and not cryptsy since they still are not up and running with the noble wallet while two other exchanges already have the new wallet and block chain running. again I have to wonder if they ever will get the wallet working or we may never be able to get our coins out of craptsy at all

[morphtrust]

also on the new noble wallet is not getting any connections, and when it fired up (loading it on a machine that has never had noble on it) it said it was loading the 1.1.0.3 version on the splash screen that shows up while the wallet is being installed. any thoughts??

***edit, I just shut it down and restarted it after it was installed and it still shows the same mismatched version number on the start up splash screen, and it still does not connect to anyone at all. so getting it up and running is impossible for me to go salvage my coins that I invested my hash and money into. Please some one message me or something if you know how to fix this.

Mining will end soon since NOBL is gonna be pure PoS; all go toward one direction finally. Personally I am a fan of hybrid PoW/PoS though.

It's confusing to see POW and POS rewards in the same format in that block explorer's history list, when they are really indicating very different things. 

The following API will clearly show PoW or PoS, and the block reward.

Code:

getblockbynumber 4359

https://github.com/eagleflies/noblecoin/blob/eagle/src/main.h#L39

https://github.com/eagleflies/noblecoin/blob/eagle/src/main.cpp#L948

It is 8% annual rate and the source code also shows 8% rate.

The PoS-II design leads to effective rate lower than 8% since the staking days are always less than those of general PoS provided the same staking conditions.

What's the client version number shown in Help -> Debug window. I see it's v2.0.0.0 (mac os; never mind the version shown in splash screen)? If no connections, adding some nodes might work, try adding the following into the coin file:

Code:

addnode=194.181.3.79
addnode=88.87.9.210
addnode=104.236.195.137
addnode=38.84.64.231
addnode=104.54.1.171
addnode=188.226.148.83
addnode=149.3.131.2
addnode=71.175.81.45

Edit, check if firewall blocks the connection, which is the case sometimes reported by people.

where the heck would I put this?? I have never had to modify anything to get it to work, kinda wondering why it would not just be updated to include this

*******Quick edit here **********
there are no files I can even open properly in my wallet folder in the appdata/roaming folder with any software that I have, it just has tons of garbage and black blocks that say null in white letters in them everywhere. I really hope this is not going to turn into a project that only programmers will be able to use because that is going to end the coin completely with no where near the support it will require for noble to ever amount to anything.

[morphtrust]

oh and one last thing on the firewall, I have 4 other coin wallets that are connecting just fine so I highly doubt that is the issue, even the older POW version of noble is working fine, and getting new block data right now as we speak, and the computer I am installing this on is in the DMZ of the router and has a minecraft server that the outside world can see just fine.
