if only 1 share is submitted and it solves the block all payment goes to the one single miner who solved the block because he was the only miner that worked on that particular block. No other miners submitted any valid shares for that block so no other miners get paid. It is completely fair because as luck could have it , it could of been any of our miners at any given time who happen to submit that winning share first. Also the block is solved instantly so your miners just go on to working on the next block and are not wasting many shares due to long polling.

You do not see this as much with Bitcoin pools because the difficulty is so high but you can still experience it if you look around, especially at Slush's pool where he still uses his own brand of proportional payout. Especially with Namecoin merged mining, sometimes you get 0 reward for some NMC blocks because it is solved before you can submit any amount of valid share and get scored.

Urgent announcement:

Do NOT use an address generated from the exchange (vircurex.com) for receiving DVC bounties. The exchange currently cannot identify and process coins received (directly) from bounties. I am working on a fix but this may take some time.

The receipt of coins that you send from a devcoind is not affected by this.

I understand that. But if you look to your stats you can see that 7 blocks of  last 54 block had only one share. Even at low difficulty (it's about 100) it's extremely lucky. And i noticed it several times from the start of the pools - even at difficulty 400. And times for these blocks are sometimes almost 2 minutes .

20702    1    12/06 7:38 pm    2 Min    1    4950 DVC

So it means that at pool hashrate of 1Ghash was commited only one valid block during 2 minutes?


I don't say there's anything wrong - just wondering.

luck is luck my friend Smiley

Difficulty is only 79 right now, DVC luck changes with every block instead of every two weeks like Bitcoin so it can fluctuate rapidly

check out the block explorer

http://explorer.devcoin.org

I could point all my miners to the pool and single handedly make the difficulty go way up in one day

the difficulty was up around 200-250 pretty steady
but then when we had this issue with the pool a lot of people stopped mining so it dropped quickly

thats why you see such a variance

Hey Kumala, is there a way to check and see how much Bounty we have coming or check and verify its been paid? Is there any way to do this?

thanks

I am currently looking into the details. The difference between the coins that you send to the exchange and the coins that you get via bounty is, that the bounty coins show up as "generate" instead of "receive". Unfortunately the devcoind does not fill the account number when it generates a block for a known address, it leaves the account field blank

There are currently two options to solve this:
1. Devcoind sets the account property for the transaction that is generated to the account that is linked to the address in the wallet
2. extend the details of the listtransactions output to include the address

In the meanwhile I will be manually checking on this, I am double checking the devcoind CSV files and compare them against all the current generated DVC addresses in the exchange to look for overlaps.

i have reviewed the csv files of the devcoin daemon and there are no addresses in them that are registered with the exchange other than one of m. in other words, all account balances are correct. the functioning of the exchange is ensured.

How much of DVC (from whole 50 000) per block is for miners? Isn't it 5000 DVC? I'm asking because i just found on pool.devcoin.org on stats page following data:

Block #    Confirmations    Time found            Duration    Round Shares    Total Amount of your reward
20734    2                     12/06 9:49 pm    1.17 Min    32                    5675.84134615 DVC
20734    3                     12/06 9:47 pm    2.75 Min    32                    5675.84134615 DVC

Because DeVCoin gives out 50,000 coins per block as compared to BiTCoin's 50, it also has 1000 times as much transaction fee. So the amount over 5000 you see in the award to the miner is quite possibly largely composed of transaction fees.

(Largely of the ones it considers mandatory. The trivial amounts also there might be voluntary ("donationed" as it were) transaction fees. Obviosly all over the 5000 ought to be composed entirely of "transaction fees" technically.)

I've been watching devcoin for a while, and I finally decided to try installing it. Here's the blow-by-blow:

Installing Devcoin-qt on Ubuntu 11.10

1. Went to http://sourceforge.net/projects/galacticmilieu/files/
2. Downloaded devcoin-qt-24-Nov-2011.tgz and unpacked it
3. Opened a terminal window and went to the devcoin-qt directory
4. ran qmake, then make
5. Needed the cURL package, ran sudo apt-get install libcurl4-openssl-dev
6. ran make again
7. ran the compiled devcoin-qt

Anyone else who compiles this will probably need some other packages. Since I have compiled Bitcoin on this system I may have already had some packages that devcoin requires.

First thing I noticed is that it uses a bitcoin "B" icon.  Should that not change to avoid confusion?

A couple more questions-- 

Devcoin-qt says it's connected to 3 peers, but the "synchronizing" has stayed at 0% now for quite some time and hasn't moved at all.  What might be happening?

Can I set gen=1 in the conf file to start generating?  Not sure how that works, but I tried creating a devcoin.conf file and it didn't seem to change anything.

Thanks!

Hi Btc_novice,

Use bcrypt. Here's an open source PHP implementation.

Indeed that would be better.  Thanks for the suggestion and links.

You get an informative post bounty, which is 1/5 of a generation share.  Please post a devcoin address and you'll be added to the next receiver list.
Is this offer still valid?  If so, my devcoin address is: 19QEeVsj53HVdrz8xxbPTH9HZ8xDYU3WaK

Thanks!

Note, I still can't get the blockchain to start downloading.... and I've run out of ideas.

There is no mining in the -qt, it is just for being a pretty client for GUI-users.


The devcoind is necessary for mining. Boost or Qt threads just would not handle mining, we had to disable mining for that reason.

The devcoind actually has the old wxwidgets stuff in it too, but we don't bother with that GUI so I do not even know if it compiles or works, it is just what came in the old bitcoin we hacked with minimum necessary hacks to make devcoind.

By minimum I mean even the names aren't changed, you make -f makefile.platform bitcoind then strip it and rename it as devcoind, and its default config file and maybe even data directory also still say bitcoin I think. I use shell scripts to invoke all the coin-daemons so my shell-script passes the directory and config file names to the commandline.

Even running devcoin-qt I still passed everything on the commandline so never actually tried just setting stuff in the config file.

Config probably works though its just the there is no generate in the -qt one.

I don't know why it isn't synchronising though. I used to find first time I run it it dies of no directory yet makes the directory then second time I run it it works. I don't know though whether the percent downloaded estimator even works, maybe it just stays at 0% until it gets to 100%, no idea really. I always already had blockchain from using the daemon when I ran the -qt and never ran it much at all.

Does the debug.log give any clues? I wonder if somewhere among the changes to the difficulty changes and so on it might have ended up leaving initial downloads thinking dofficulty is wrong or something maybe it is piling all the blocks into the orphans pile or outright rejecting them or something.

Thanks for the info.  I'll have to see about running the daemon. That may fix my block downloading problem too.

Sometimes when I load devcoin, for whatever reason, I don't download any new blocks.  Usually when I try again later it works.

By the way, after I posted I realized that an informative installation post gets double the post bounty, so you get 2/5 of a share.  I've updated bounty_6 accordingly:

Back to balance questions:

Estimated: 1925 DVC

Unconfirmed: 328061.45397357 DVC

Total Balance: 143024.55413 DVC

soptik2, are you seeing similar balances?  Looks like we're around similar hash rates today.  


i'm having this:

Estimated: 1980 DVC

Unconfirmed: 170168.99228544 DVC

Total Balance: 1198445.4249 DVC

These are higher values than yours - because it's sum of my 2 accounts (they were merged). I think that during last 24 hours pool is computing balances correctly.

But one little strange thing remains - if you look into pool block history, there are many blocks which has only 1 share - so whole amount of 4950 DEV for a block goes to one miner. During last hour - it were 3 blocks. Is it normal?

So 13 hours later, I'm at 715,000 Devcoins.  This means I'm earning on average about half a million devcoins a day and could possibly be up to 3 or 4 million by the weekend.

Just one additional check to make sure I'm not getting too many coins.  I don't plan on selling right now given there are only outstanding orders for 11 million DVC for only 3.5ish BTC on vircurex.  Seems best to hold speculatively at the moment to see what the "devs" do for the new chain.
