New algo implementation + some wired issue ! Help

[XaiZou]

Hi,

I implemented a new Hard memory algo, everything works perfectly , genesis block, nTime, etc are set and all good!

Code:

bnProofOfWorkLimit = CBigNum(~uint256(0) >> 8); // low diff for very slow algo

[color=blue]genesis.nBits[/color]    = 0x2000ffff; // i tried this

genesis.nBits    = bnProofOfWorkLimit.GetCompact(); // and tried this and i believe its same as above

tow clients(wallets) working on 2 PCs, one is solo mining ~500 Hashes/s

Block are being generated on PC one and PC tow is also accepting them.


BUT after each block found i get the lines in red WHY    ?:

That means there is something in your code for verifying blocks that is not properly verifying the blocks.

This is really wired, i didn't touch anything in the code yet , what i did is just change the values in chainparams.cpp and hashblock.h + added the algo files.

I noticed once a block is found the wallet freeze for like 10 sec before it shows in the transaction list, and the other PC wallet also freeze 20 sec before accepting the block.

also before changing the algo it was whirlpool and was good with no problem.

any more ideas ?

Well you should probably go and check out the code for block verification. There might be something there that is causing your problems. It might just be something that needs to be changed to match your algo.
