Well, when you developing your own project, don't be silly and don't copy it from someone.

Even they copied our link to Youtube

block explorer end exchange??

why are there so many people mining this claiming its 63 dollars a coin are you all retarded?  There is no exchange but I am sure if you tried cashing in 6000 or so of these a day someone might call bullshit on the play here.  Any way why is there like 40 miners mining something with no value?  Brain Damage much?

No exchnage though right/?

Hi all,

it's just a little fork for big "little" stake : https://github.com/patjar/sumcoin.git
 

Thanks! I'll try hard.

The source code is common for Linux and Windows.

As a general rule, for good reasons of security, the executable of a wallet must
always come from its Dev, which in this case is gone, perhaps out of shame.

So excuse me, but I do not feel like to send you the program re-compiled,
but perhaps I can still be of help, I found how you can do alone a patch
to the executable code.

Download from the first page of this thread the original program for windows,
and upload it in the binary editor you prefer.

Go to the location 000FF5D9 (1045977), here you should see this series of bytes:
000FF5D9: C0C54EECC483F863771D

the byte that contains the "63" (99 in decimal) is the number to be changed,
you can put 05 as the first patch indicated, or 01 as suggested by Patjar.
Once modified, the result should look like this (in the case of 6):
000FF5D9: C0C54EECC483F805771D

Once done, if everything matches, save the file with a new name, the work is finished.  

At this point the new wallet is now fixed, and if you have some coin in your wallet,
it should be able to go into stake without getting stuck.
Hypothetically speaking.

Bye Bye

But I am on Windows. Can someone compile win wallet with this fix?  I have just academic interest.

You can find the original file that you must modfiy in Linux repository, here:
https://github.com/ilsawa/sumcoin/blob/master/src/wallet.cpp

Whereas the Dev has disappeared a long time ago, I think now that the currency
has mainly academic interest.

Bye

Guys, where/how can I find wallet.cpp file?

Have you seen when the internet connexion stop, the stack continue and work ? 
see ya

I can confirm that staking is working for me after changing the number 100 to a 1 in wallet.cpp on line 1701.

I never expected Sumcoin to make it to the staking phase since the dev seems to be gone, but some of you kept on mining and it looks like we made it!

Now where's our community at? I love the idea of 1000% POS! Let's get this thing going!

Is there any way to get our dev back, or maybe someone could fork the github repo and push an update with the staking fix?

This coin has big potential!

With this modification it stopped in middle of my stake (same error) so i decide to put 1 and it restart perfectly in POS function up till now.
Raspberry pi cost nothing (30euro) you can have many, you only need usb for power (3watt) and ethernet for connection (key wifi on usb)
it's debian system  (raspbian) easy for security and virtualize (hard with qemu),
or you can directly compile your wallet qt on it (hour) and turn on for or five wallet in the same time (start one by one in different workspace)
24/24 hours with no noise  
So for POS nothing better with usb memory for swap if you need more memory for compile in the same time (git pull) .
Use source for compile to raspberry, the version of git do a bug with gcc.
of course you can directly connect to your display with hdmi and everything in usb or connect by rdp or vnc or redirect ssh
Do you know if it's possible to deactivate limit of 5 coins send ,cause little blocks hug the raspberry cpu and have you some information about this coin in the future ?
Bye Bye

Glad to have been helpful. 

I believe that some blocks have already been "collected" in a series of larger blocks automatically.

Generally, it happens quite rarely, but at the beginning of phase POS when the "coin blocks" are very old,
it happens more often.
And now we need to have many blocks of coins ready for the POS, so as to maintain a stable frequency of the Pos blocks.

Unfortunately, about the limit of the 6 input for each transaction that make this coin a little problematic, I think that can
not be circumvented easily, for example by increasing the size of the block, without necessarily changing the programs
which run on the server side of the seed node.

I've often read about the rasp berry, but I've never studied it.

What advantage implies in practical terms?
It has enough processing power and memory to handle several independent wallet?

Bye Bye

wow thanks a lot, it's work
i recompile for linux and everythink it's right
before i try to put in many wallet and with control coin to have a big block but i stopped and wait a solution
so good POS for you i try to put in my raspberry pi (when seedcoin growth ended)

The Good News
Exactly at block 80000 the mix POS/POW stage is started as by program, the data of 1st POS block:

}


The Bad News:
The bad design choice which plague this coin from its born, i mean the too little block dimension,
now produce a constant error, which interfere with the generation of new POS block:
ERROR: CreateCoinStake : exceeded coinstake size limit

You can find it the debug.log.


The good news, for this error I m currently testing a wallet workaround, which don't need a hardfork.
AFAIK  It seem to work.

In file wallet.cpp change the line 1701 to:
            if (txNew.vin.size() >= 6)     // In origin was 100     **  fix  em52


Bye Bye

5000 blocks left before POS 

Wait for It...

lol. A coin with no-pools and without community support It's not going to be "productive" for you...
PoS 1000% (?) haha continue waiting...

No problemo, easy solo mining and perhaps one day POS 1000%

Coinminers will shut down the pool for this coin on 19.08.2014

Thanks for mining with us
