final fix for this issue hopefully
(did i mention i am on European timezone? where is my sleep)

the block with bad timestamp caused a negative value in difficulty calculation
there is now a fallback
github updated
windows client here:

I have a few of those rejects

Why nBits below minimum work?
Quick google search: This sometimes happens when you try to change the minimum network difficulty but forget to update the nBits value. Here's a fix:

Quote

If you increase the minimum network difficulty, you have to calculate the right nBits for genesis block.

Try this:
Code:

printf("min nBit: %08x\n", bnProofOfWorkLimit.GetCompact());

after this:
Code:

   printf("%s\n", hash.ToString().c_str());
   printf("%s\n", hashGenesisBlock.ToString().c_str());
   printf("%s\n", block.hashMerkleRoot.ToString().c_str());

this will print a hex value, set this to block.nBits.

and gen a new GenesisBlock hash.

Also, this can happen (?) if you didn't delete peer.dat and older clients try to feed you with the old blockchain

Now, I'm not a dev. I have no clue about what I'm writing about. You guys are much smarter than I am, and probably can make some sense out of it

i removed the sanity check that didn't make any sense, but it shouldn't be needed now

github also updated
but you need to reset 3 versions back before pull or download a fresh clone
took no chances with the errors reports

we should be creating blocks, if you're getting rejects please let me know

hum, don't understand, can't load anymore !

I deleted my local copy and cloned from git again (not just pull), built again and still

Code:

faircoind: main.cpp:2558: bool LoadBlockIndex(bool): Assertion `block.GetHash() == hashGenesisBlock' failed.

Here's something that could possibly help you.

Quote from: Question

After compiling on Linux,

I've got

./cryptobuckd

cryptobuckd: main.cpp:2562: bool LoadBlockIndex(bool): Assertion `block.GetHash() == hashGenesisBlock' failed.

It doesn't work

Quote from: Answer

Compile version 1.0.0. first this will create your genesis block. Run 1.0.0 for 10-15 seconds. Then run 1.0.2 it will continue to load the chain as it should.

So... maybe compile the very first version of Faircoin first, then compile the latest version?

well I pulled back a backup and still can't start the application

like drumingspz said... something is off with the genesis block (today was supposed to be a transition between last client and current ... older clients can't connect)

So while the backup failed too,

I got this from the logs

Code:

I'll wait for the fix since pulling back last version can't make me load the client still

I am a coder, but haven't looked at crypto coin coding so I may be off base, but it seems to me that if you can't nail down the genesis block, then everyone would have syncing issues - which is what we are seeing. If you can't properly sync, then mining will give us all kinds of weird errors. I would start the hunt at the genesis block instead of trying to fix a mining bug that may not exist...

Just my thoughts, could be right or wrong

the error doesn't seem to make any sense (says target below min target, even though it clearly isn't)
i added some logs
can anyone who can mine locally please get down this client or update from latest source
and paste the reject reason from the debug.log

unick? you around?
