Transaction fee is too big (0.005) for such difficult to mine coin.


+1

Too big!

every transaction destroys a portion of the supply, since the fee's can't be mined, theoretically meaning the coin is a bit rarer with each transaction.

no, i bricked the source in the process of compiling for windows. i tried my best to put it back to the way it was.

This coin is going to change the world!


since r3wt bricked the sources i'm going to manually go through and prepare a clean copy of j-coin straight from the mehcoin repository.

I thought you were r3wt. Are you talking about yourself in the third person?

yeah, i am but apparently some people haven't realized it yet.

It compiles but assert (see my post above where I talk about the suggested fix and how this fix doesn't work in many ways).

Also the source .7z contains the mehcoind binary in src/.

ok i will give you the correct variables. its up to you to plug them in

Code:
block.GetHash() == 00000d2ce10281089f47d707942122e011925e22a33aa06dd13959b12c1b80db
block.hashMerkleRoot == 0e7abe3621183101283aa99a5b1fa9d345a1a6f56d90faa8b384b3af6e0d69bb
block.nTime = 1375158531
block.nNonce = 829036
CBlock(hash=00000d2ce10281089f47, ver=1, hashPrevBlock=00000000000000000000, hashMerkleRoot=0e7abe3621, nTime=1375158531, nBits=1e0fffff, nNonce=829036, vtx=1, vchBlockSig=)
  Coinbase(hash=0e7abe3621, nTime=1375158511, ver=1, vin.size=1, vout.size=1, nLockTime=0)
    CTxIn(COutPoint(0000000000, 4294967295), coinbase 04ffff001d020f271d5475652c203330204a756c20323031332030343a32383a303620474d54)
    CTxOut(empty)
  vMerkleTree: 0e7abe3621
SetBestChain: new best=00000d2ce10281089f47  height=0  trust=1  date=07/30/13 04:28:51




That breaks down to:

merkle = 0x0e7abe3621183101283aa99a5b1fa9d345a1a6f56d90faa8b384b3af6e0d69bb

genblock = 0x00000d2ce10281089f47d707942122e011925e22a33aa06dd13959b12c1b80db

nTime = 1375158531

nNonce = 829036

please let me know if that fixes it.

What is this now, a puzzle? A game where the goal is to successfully compile and run without asserts a coin that is released? If so this coin and memorycoin are the clear winner in that category.

All those values don't even match what DogTownHero has posted in his (not-compiling) main.cpp in this post (https://bitcointalksearch.org/topic/m.2858033), nor the source package on gdocs.

So where are you getting those values from?

The commented out code is what's in the posted source .7z (1st post), and what's below is what he posted in the link above. Your values are different from both. So wtf?

Code:
<         // Genesis Block:

<         //   CTransaction(hash=4a5e1e, ver=1, vin.size=1, vout.size=1, nLockTime=0)

The commented out code was what shakezula commented out in the original mehcoin sources. since everyone is having such a difficult time with this, and since r3wt bricked the sources i'm going to manually go through and prepare a clean copy of j-coin straight from the mehcoin repository. i'm sorry about the inconvenience.

Just in case anybody needs it (or is to lazy to edit two lines from the YAC cpuminer). Here's a modified version of cpuminer that should work with j-coin. Note, I just started testing it and I haven't gotten any blocks yet.

Can't run with win7 64bit ,how to do it?


if you installed with Jinstaller:

1. right click the program icon on your desktop
 
2. click properties in the drop down menu.
 
3. then click on the "Compatibility" tab.

4. select the checkbox that says "run this program in compatibility for..." "Windows XP Service Pack 3"  should be the first option. if its not, select it from the drop down menu.

5. click apply.

6. run the program.

The "compatibility" mode can't run yet, the application just stop. Angry
