is it up? it says not responding...

Yes will look into it, thanks for reporting issues.


nice, thanks!

New pool lauched. (updated - please ignore can't get it to work - sorry folks)

Come find the Tigers in TreasureQuarry's new p2pool for Tigercoin at  available at http://tigercoin.treasurequarry.com:14377/

Uses Tigercoin Version 1.1 to ensure those Giant Tigers (superblocks) are shared out to miners when they come after block 4000.

Low 1.5% fee.  Reliable server based in Dallas, USA.

Use a unique Tigercoin address from your Tigercoin wallet on your PC as your username, and anything as your password.

The pool should be considered experimental currently until the blocks start coming through.

Happy mining at TreasureQuarry!

There is a bug with datadir like in nbcoin.
When starting tigercoin-qt on windows with -datadir=c:\dir parameter, all data except debug.log is located in correct folder, but debug.log resides in %Appdata%\tigercoin

Please fix it.

Nice, please upgrade the pool to Version 1.1 which is just released. Source code updated in github.

Version 1.1 is released. ** This is a mandatory update **

Please upgrade to 1.1 within 24 hours (before block 4000, now we are at block 1893, target blocks 1 day=1920 blocks - so we have about a day to upgrade to V1.1).

The version 1.1:

(a) Fixed the issue with random superblocks
(b) Added more checkpoints.

Links at OP for downloading windows client and source are updated.

I tested the fix, the random numbers work fine with the fix.

Agreed!  The superblocks make this coin Tigerlicious.

I create a p2pool for this coin.  Let me know if you have any issues



I also have my own post if you have any issues:

https://bitcointalksearch.org/topic/ann-tigercoin-added-to-wwwjapoolcom-289782

I've added TGC to the PhenixEx candidates. Vote on it in this poll : https://bitcointalksearch.org/topic/poll-which-coin-would-you-like-to-see-on-phenixex-285906 to get in on an exchange ASAP.

The fix should be applied fast while the coin is still unknown

Wouldn't it be better to start from the 50th character or thereabouts?  That way, even if the difficulty rises extremely things should be safe.

Thanks. Sent a little donation.

Some people asking about why they don't see superblocks. We checked the code and its behavior, we did see an issue. Let me explain it here:

The random calculation code:


what this means is that the program takes the previous block hash, extracts 7 characters from the hash, starting from 4th position in the hash, and use it as the seed to generate a random number, then the random number will determine if a block is superblock.

This scheme works fine for all other coins that has random blocks, and works for this one at the beginning (< block 300). But after some time, the generated hashes have a lot zeros in the beginning, for example:


in consequence, the cseed string, instead of being random, becomes some fixed strings like "0000000", "0000001", "0000002", etc, and none of these correspond to a superblock  .

I don't know why the hash have so many zeros at the beginning while at the start (blocks < 300) everything is fine (at least 3 random characters in the seed). This probably has to do with diff etc.

We are two ways to proceed:

1. Ignore it, and think in general there will be no superblocks in this coin. I know it is bad, but if the hash string changes back to less zeros (as it will likely to), we will see superblocks again like at the beginning of the blockchain. At least for this we don't need to do a forced upgrade / hard fork, so the mining will go smoothly.

2. We can fix the code, by extracting the seed string from, say, 11th character in each hash. This way, the randomness will be guaranteed, and we should see the superblocks as designed. The problem is that it will be a mandatory upgrade of the client for everyone. I can switch at certain block number, say block 3000 (now we are at block 1750), extracting seed from 11th character instead of 4th character.

Please let me know which you prefer, I'll do whatever the community agrees upon.

diff now 2432, not worth to start now guys 

look http://bit.usr.sh:2750

I'm sitting on more than 80 blocks but I haven't yet hit a superblock...

Has anyone hit one yet?

I see superblock before block 177

but nothing after.

There is something wrong

I've started Tigercoin block explorer:
