A question about the API:

Currently the API is like this (in php print_r() format):

Code:
Array
(
    [user] => Array
        (
            [total_rewards] => 0.0
            [paid_rewards] => 0.0
            [unpaid_rewards] => 0.0
            [past_24h_rewards] => 0.0
        )

    [workers] => Array
        (
            [user.worker] => Array
                (
                    [hash_rate] => 0.0
                    [valid_shares] => 0
                    [stale_shares] => 0
                )

        )

    [pool] => Array
        (
            [hash_rate] => 697
            [pps_rate] => 0.00096512
        )

    [network] => Array
        (
            [hash_rate] => 22763
            [difficulty] => 0.76679615
        )

)

All the workers' names include a dot, and it's 500 if I use the data like this:
Code:
echo $lp["workers"]["user.worker"]["hash_rate"];
How to use it correctly?

Pyramid scheme

Since the aforementioned reasons mean Litecoin has no future potential, it effectively functions as a pyramid scheme, rewarding those who get in sooner at the expense of those who adopt it just before it finally fails (and are left with nothing). This is not the case for Bitcoin, since it has significant potential to become a long-term currency and continually be beneficial to adopters no matter when they begin using it.

and it's protected now because of a latest violation of RR3 (I know they don't have that rule, so edit war?).

however litecoin and solidcoin are the only cc`s on bitcoin wiki Wink

Can someone explain me how to remove keypairs from wallet.dat?
I need to remove one address . . .

seems like pywallet will do that. (You might need the private key to delete the address( (haven't tried). You can also use pywallet to get the private keys from your wallet.)

Is your wallet spammed?

Since I'm not running a bitcoin daemon now, I'll pay by withdrawing from exchange to your address (or I'll pay from my wallet if you request that).

I'll do that before 1515 GMT if all things are working smoothly.
29  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Litecoin - a lite version of Bitcoin. Launched! on: November 23, 2011, 02:49:17 PM
Anyway, is the TX spam now completely over officially or is there some other drips of dust left ? How do I scrub my wallet ?

According to block explorer, the dust spam is still there.

Use 0.5.0.8 (50008) client to move your coins; by default txes below 0.0001 is ignored now when creating a new tx. (Haven't tried though, just saw the line in getinfo)
30  Economy / Services / Re: 3DMark11 Advanced Edition worth $19.99 for half price ( now 5 BTC ) on: November 23, 2011, 02:15:07 PM
Maybe the ppl here just don't care about it.

However I'm interested Wink

AND i'll pay in the original price.

only one question: any time limit on activating? I may need this in the near future but not now.
31  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Litecoin - a lite version of Bitcoin. Launched! on: November 22, 2011, 02:19:49 PM
The point is spending those coins will slow down the client right now b/c it takes forever to collect enough 0.00000001 LTC to make up a large enough value to send. So I changed the create transaction code to ignore these tiny values by default to speed things up. If you really want to spend them and wait forever for the client to create the transaction, you can by passing in a tiny min input.

You could also ignore these transactions (under the min amount) when checking blocks for wallet transactions. It will help improve the general performance of the wallet going forward too.

it now takes about half a minute to load the blockchain on my server. If it can improve the loading process it would be great.
32  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Litecoin - a lite version of Bitcoin. Launched! on: November 20, 2011, 09:13:40 AM

 Hello,

Is there a list for processor (M hashes/s)  for Litecoin?? Similar to what we have in Bitcoin: https://en.bitcoin.it/wiki/Mining_hardware_comparison


 
What brings this is available types of processors Intel i3/i5/i7/Xeon and AMD X6, Opteron and FX .......

Also a person can get a cheap Opetron (possibly old) from ebay to mine for Litecoin......

Regards,,,,,


There is a list on litecoin wiki:

https://github.com/coblee/litecoin/wiki/Mining-hardware-comparison

However there are not so much info.

How to dump all private keys from a wallet without the mess of txes?

I need to dump some private keys from my spammed wallet but pywallet's dump also "take care" of those txes. Then my server nearly dead because pywallet ate up almost all ram and swap.

the reason I wanted the private keys is my vanity address (below). I didn't save the private keys to another place but i still want to keep the address (took 12hr to generate that.)

Hmmm I'm receiving lots of micro transactions today. Mostly to my public address in my signature.

Was wondering where are they come from...
35  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN] New PPS Litecoin pool on: November 05, 2011, 03:22:33 PM
Hi,

On your site you said this:

Quote
(In case you are wondering, 65536 is the average number of hashes to be computed in order to find a share. This is not the same...

IMO You should change it to "65536 is the average number of shares to be computed in order to solve a block on difficulty 1". As you set the pool's small target to 16 bit, it takes 65536 shares to find a block on average. So, the way the earning are calculated should based on shares. The figures are just happened to be the same, as 65536(hashes/share) * 65536(shares/block) = 4294967296 = 2^32(hashes/block).

Just think, if you change the small target to 15 bit, the effective difficulty for miners are actually decreased, thus more shares are required to solve a block(131072), and to find a share you only need 32768 hashes. In that case the PPS should be 47.5 LTC / (131072 × Current Difficulty), not multiplied by 32768 on the denominator.

Sorry, misread, meant effective indeed.

Looks like it's moving average? (look at the first pool block)


i got to that yesterday aswell

currently it's 24963. Sounds reasonable

well lets have a look ... i got that far yesterday aswell
first of i use  bcpow(2, 16) = 65536

so yea bcpow(2,16)*0.38087351 = 24963

reason i think was something wrong is if start to change the 16 nothing makes sense -.-

lowering the 16 lowers the result wich shuld higher since it would make the shares easier = more of them, but it lowers the result

maybe just me thinking to much over it but hey Smiley id wanted to be sure before put on page rather have a none working there then an inacurate i cant defend Smiley

hmm why does 16 change? it's set by you on the pushpoold

24693 means at current network difficulty and your set easy target, it tooks 24693 proof of works(shares) to solve a block. So when network diff. changes it changes as well.
37  Alternate cryptocurrencies / Mining (Altcoins) / Re: [ANN] Pool-X.eu - 1.1mh/s 0% fee, free withdraws, 1 LC To blockfinders on: November 03, 2011, 12:42:33 PM
localhost the estimated diff ? no suchh thing

theres effective, the red line: = effective diff
theres actual, the blue: the actual diff for each block

reason green isnt working is the pool uses
rpc.retarget.bits=16,

and i havent gotten head around how to make the formula to calc avg shares for a block on certain diff with retarget on

feel free to drop some working math lol Smiley i was sick yesterday i looked at before heading to bed with no luck.... gonna make my coffee and have a look during the day

Then it should be 65536*diff

65536 comes from 1/1.525878906e-05

currently it's 24963. Sounds reasonable

Now that you mention it, what's supposed to be the difference between actual and estimated diff on the graph there? http://pool-x.eu/blocksAuth

The actual diff is not working, and what's est. diff?

I mean the easy target the pool gives out to the miners. That target is much easier than current network target. I dunno how to call them...
40  Alternate cryptocurrencies / Mining (Altcoins) / Re: [ANN] Pool-X.eu - 1.1mh/s 0% fee, free withdraws, 1 LC To blockfinders on: November 03, 2011, 05:41:24 AM
Hi g2x3k,

The `actual difficulty` graph on Block Stats page is not working now. Looks like it's currently calculated by diff*100, so I assume it's used for PoW diff 0.01. Your pool's PoW diff is not 0.01 right...?

Code:
mrx@SERVER:~$ ./diffcalc 0000ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
target = 0000ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
nBits = 0x1f00ffff
difficulty = 1.525878906e-05

That target comes from direct curl and reversed...
