API Temporarily Unavailable

The pool has been seeing a very large increase in the frequency of distributed brute force attacks on the login page.  Over time these attacks can cause the website to slow down.  Hundreds of IP bans have so far done virtually nothing, and the easiest way to stop them is Cloudflare's "I'm Under Attack" mode.  Unfortunately, this mode also kills most API polling applications due to requiring a browser verification before a user is passed on to the backend.

Whitelisting IPs will allow users to bypass the block, but very few users have static IP, and allowing too large of an IP range into the whitelist eliminates the purpose.

I'm working on an alternative right now to restore API functionality during times where the site is in this mode.  If you have developed an API polling program or use your own API polling script, please send me a message via the forums, or an email to webmaster@btcguild.com .

Not that API access is critical for me, but would whitelisting a Dynamic DNS work?  Just curious, not asking for it to be done.

On a non pool related note:  Any users who are fans of MMORPG genre games may be happy to know that RIFT has gone free to play this week.  RIFT has been one of the higher tier fantasy-themed MMORPGs in my opinion, and I've decided to hang out on it once in a while.

If you play the game or are interested, send a message to Eleuthria on Shatterbone, I've decided to form a guild on there (BTC Guild).

Yea got that email.. nice huh.. I haven't played for a while ... might hafta come join ya!

Join me in hosted mining.  And always use 2 Factor Auth whenever possible.

I don't know either, but what's the problem with just not mining anymore (or somewhere else)
and about next day retrieve the remaining funds, then just forget about it, yourself?

Why do you want it explicitly DELETEd?

Getwork is still alive, but very unsupported.  Unless a lot of people are complaining, the getwork servers are left on auto pilot and not monitored for performance decreases.

You can not delete an account.  Simply abandon it and it will eventually get pruned into an inactive database.  However, the earnings and payout history related to an account will never be removed in order to have proper accounting records of outgoing payments.

As many of you have seen, the site has mostly been in the Cloudflare 'Under Attack' mode since yesterday.  I was away from my main computer and did not want to have the site performance suffer.  Many API users should have still been able to access the API from their home/office, but phone based applications probably had issues.

The site is back in normal operation today.  I'm continuing to log and blacklist the attacker, which is helping keep the site from having the performance loss we've seen in the past.


Users of BTC Guild:  Please take this time to consider if your username/password combination has been used on any other site.  This brute forcer is NOT using a random guess.  It is absolutely comparing against a HUGE database of leaked username/password credentials from other websites.  99.9% of the attempts don't match a BTC Guild username at all, and luckily BTC Guild's error message doesn't give insight to whether or not a username guess was valid [bad username gives the same error as bad username+password]. 

However, if your password is repeated on a site that leaked their database at some point, your account is at risk.  Just as an example:
The brute forcer made over 4,000 attempts for usernames between 'ketan9binny' and 'KingCid'.  Each one had very specific username/password combinations.  Some common usernames [kevin for example] had multiple attempts with different passwords, indicating they are comparing against multiple leaked databases.

You should also make sure timing cannot be used to deduce status, or maybe you do that - add a random delay or make sure that any timing difference is much less than network effects.

16100  241685  34.00440500   

Anytime the value of inputs exceed the value of outputs the network considers this a mining fee and awards the difference in value to the miner along with the block reward.

In this case the transaction responsible for most of the mining fees is http://blockexplorer.com/tx/6a19240a85ad189d404098af0a80f7f894a7e7916f034cd473f5569a4d85a499

It probably happened because someone manually assembled a transaction and didn't get the inputs and outputs right.

It doesn't happen that often.

Question:
is it possible that NMC implementation could have a bug?
I have the exact same hashing power on another pool, also merged mining, I am doing the same amounts of BTC but the amount of NMC is about half here.
nothing that takes my sleep away, NMC worth very little today, just wondering if it is something wrong there or just bad luck in nmc the last 3 or 4 days.

I'm pondering the same here, I have half of my mining power pointed at Bitminter and my name coin income is 4-5x higher then here.

Well difficulty has doubled so I guess they were mined. But they looked low to me too...

The pool is finding roughly 1 in 3 NMC blocks.  That is what is expected when the pool's hash rate is roughly 1/3rd that of the NMC network.  There is no bug in the assignment of NMC either, I can clearly see that 97% of NMC block rewards have been assigned to miners.  My only thought is maybe BitMinter only allocates NMC to miners that have NMC wallets set?

BTC Guild's implementation of MM does sacrifice NMC rewards in order to keep BTC efficiency completely untouched.  However, that would only be ~10% of a difference, not 75-80%.
