No, it's not the simple and fastest way to check.  All your program does is check whether or not an address has a balance of more than 20 coins.  Your program will fail at the next block halving since the reward will only be 12.5BTC.

If you're going to implement something, do it right.  Kano has explained exactly how to do it.

Well ... the correct way to check it is:

Each time there's a new block check either:
1) The coinbase sig contains /solo.ckpool.org/
or
2) The 2nd address in the coinbase transaction is 1PKN98VN2z5gwSGZvGKS2bj8aADZBkyhkZ
 (and there are 2, and only 2, addresses in the coinbase transaction)

Then if the other (1st) coinbase address matches the user's address then they found the block here.

Though it's probably easier to simply check if the first address in the coinbase transaction is the user's address since that could only be a false positive if the same user used the same address and found a solo block somewhere else.

Checked out your code... it'll ping jackpot every 10 minutes if you happen to have more than 20BTC in your address.  Might want to consider another way to notify people if they've actually hit the block, since just checking the balance of an address is no indicator that the user found a block.

Thanks to both seoincorporation & MagicSnow for finding the bugs. Both will be paid as soon as we fix these bugs. We already have MagicSnow's address. Requesting seoincorporation to PM his address too. Anyone else may report their further findings.

Only include a captcha on that "Create a New Support Ticket" section, and your site will be ready for the launch.

cheap?i doubt it

Will be interested in your service in near future, prices are affordable too, good luck.

good man!

is the example carbonic website a (basic responsive) website. Like you are offering for .175 Btc?
thank you

Would you mind answering my questions from before ?

Maybe the fact your ubuntu is 32-bit and not 64 has something to do with it?

Try looking through the config.log file...
