Graph of blocks generation rate (now near 2 per minute)

That's a great graph! How/where were you able to generate it?

Just a 5-minutes PERL script and excel Most time takes getting info via RPC, near 30 minutes for getting all info (perl just sends messages to console and parses results). Now I'm creating such graph for difficulty, it'll be ready in ~10 minutes - you'll see amazing growth during last blocks

China has been in the promotion, but also please producers more perfect program, thank you!

Like a coin!

How much is the total?


DTC Wallet ：D6UT6vhcN4ESGwp5DWoQiTamddbTZCnLrR

[maxsolnc]

So three charts together. (3rd chart has less little blocks than 2nd - just noticed it, can add blocks later)

Dependency of blocks generation speed on time


Dependency of difficulty on blocks number


Dependency of difficulty on time

How much is the total?


DTC Wallet ：D6UT6vhcN4ESGwp5DWoQiTamddbTZCnLrR

Total for now: 579528 DataCoins
It is because of high speed at the beginning (as usual for all coins), see my charts above. It should be produced near 20K coins per day in very near future, possible in 2-3 days.

'Perfect program' - if you mean wallet, developer promised to work at that. Hopefully we have him in this thread soon. Anyway we can create some add-ons for original wallet to get additional features.

I have about 100 machines ready to mine datacoin but what miner to use??

(its all ubuntu 12.04)

You should build it with instructions like
https://bitcointalk.org/index.php?topic=259022.0
you only need to replace primecoin links with datacoin, all other actions - the same (build gmp, build datacoind). If all machines have the same system and architecture, you can compile daemon only on one of them, and just copy datacoind and config folder to all of them.

sssshhh 100 machines ...yikes i am getting zero coins as it is. Don't do it, bad idea go to prime or quark

Maybe there are 100 machines with 2 cores on each? I was mining with 10-20-25 32-CPU amazon instances for some time, and I cannot say that it gave me very great amount of coins (like 20-30-50%   ), also I sold some of them to pay bills

edited: there are keywords for this guide in OP post, so I didn't reveal something

Grrr... they all have ubuntu 10... can't install dependencies.
No problem... gonna use to mine other way...  right now i'm mining only with 2 computers

getprimespersec
1st) 1917
2nd) 4968

try to build some dependencies from source, sometimes it helped me for old ubuntu versions.

Pretty cool! I didn't realize this was possible to generate "after the fact" purely from blockchain data. Nice to learn something Can you give any tips as to which RPC calls were used or any available perl or other language script I can learn from? I can see the list of RPC calls at https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_Calls_list but not sure which I would use to get generation rate or difficulty data from the past. Thanks for sharing these graphs at any rate!

you should run getblockindex (number of block), you'll get block hash. After it you should execute getblock (hash) and receive full info about block, after it you can parse it and do whatever you want
small script to get csv in format BLOCK_NUMBER,DIFFICULTY , you can run it on any linux system with datacoind up and running

Code:

use strict;

my $hash;
my $diff;
my $block_num;
open MYFILE, ">result_diff.csv";
$temp = `datacoind getmininginfo | grep blocks`;
$temp =~ /blocks" : (\d+)/;
$block_num = $1;
for (my $i=0; $i < $block_num; $i++)
{
        $hash = `datacoind getblockhash $i`;
        my $temp = `datacoind getblock $hash `;
        $temp =~ /difficulty" : ([0-9\.]+)/;
        $diff = $1;
        print MYFILE "$i,$diff\n";
}
close MYFILE;

you should run getblockindex (number of block), you'll get block hash...

Perfect, thank you. I had no idea that the unixtime was stored in the blockchain which makes this all possible. I think I had it in my head that the actual time of each block was not permanently stored in the blockchain (please correct me if I'm wrong).

Anyways, please let me know if you accept small tips in Datacoin

[maxsolnc]

I created small Datacoin block explorer, just experimental one with practically no functions (and css )
I had very little time for it, wasted most of time for understanding communicating of perl-cgi and datacoind...so no time for creating 'beautiful page' at all, I can do it a little later.

It runs on small amazon instance, don't overload it please Now you can see block hashes here (enter block number)

I'll add other features soon when I have a little more time

Datacoin block explorer (dev version) updated, link also updated. 'Get transaction info' functionality added!

Can not do a website, so you can very well in China's development, but also more easily accepted by Chinese people. Now the Chinese domestic many people ask DTC《Datacoin》 official website address.

[tubbyjr]

I almost feel that we need a relaunch of this coin, with a nice official site, and logo implemented client side, as that guy previously is saying. The developer has had a nice idea he added in, but doesn't seem to be too interested in further development.

[maxsolnc]

It really takes time for network stabilization, but now it seems to be stable. I think I can create simple site (like official sites for yacoin etc), site and logo aren't the main problem. I see difficulty growing a lot, so many people started mine Datacoin. Also anyone with strong development skills can add some features to wallet if developer won't appear (or just create some independent add-ons to wallet)

[simbo]

I have some knowledge in C, C++ & others, working on my personal alt coin at the moment. If needed, I can chip in to extend features.

Regards.

Very good! PMed you.

He said he is working on the wallet to incorp the new features, perhaps he just does not come on the forum much. However yes he should be a little more active really to give confidence.

Really though there is nothing stopping anyone making a website for this coin.
