A keyed-hash message authentication code (HMAC) is a specific construction for calculating a message authentication code (MAC) involving a cryptographic hash function in combination with a secret cryptographic key.
The cryptographic strength of the HMAC depends upon the size of the secret key that is used. The most common attack against HMACs is brute force to uncover the secret key. HMACs are substantially less affected by collisions than their underlying hashing algorithms alone. Therefore, HMAC-MD5 does not suffer from the same weaknesses that have been found in MD5.
SD Classic uses HMAC-SHA512.

Scrat, the win odds on your site are terrible, downright fake(they can't be though). Your website defied statistics and probability more times than I could count. I know you cannot manipulate the games, but perhaps you've chosen HMAC-SHA512 instead of SHA512 for a reason. Or the 1k min bet, when we should have access to full 8 decimal precision betting. There's a saying that the most transparent person is the one that is hiding something.
This is very true. See below. You could say it's bad luck, but this has occurred multiple times where I couldn't get the captures. Not complaining..... Just saying.

HMAC(A, B) is just a more secure way of hashing compared to throwing a concatenated A + B into a hash. HMACs are used by all dice websites.
If you make 100 accounts, then a few of them might be unlucky. Some of them will be lucky as well, but many wins in a row aren't beneficial in martingale. Of course rolls have no memory, so an unlucky streak can happen to a player playing for the first time.
Every roll ever made is available on the website as a database dump for statistical analysis, something that only a handful of dice websites provide.

False, this depends on the hashing function used.

SHA3 (and a few others) aren't vulnerable to length extension attacks but we're talking about the SHA2 family here.

Yeah sure, but situations with a probability of <1% are common. Is the only place where you lose 7 times in a row and happens over and over again.

7 losses in a row will happen all the time on every dice website (on 50% odds). If you use a script and do more than 10000 rolls, 12-13 streaks will have a high chance of occurring once or more.
Check the database dumps. House edge is very close to the claimed 1%. Results remain provably fair.
I've seen plenty of large streaks (win or loss) on other websites too.

so this game ranks up there on the $hit list too..hmm 16 loss streak at 2x is one 2^16. There is, at any time, a 1 in 65,536 that your next 16 rolls are a loss streak. With millions of bets and people making 100000s and even millions of bets for those using martingale scripts, such streaks are bound to happen. The same happen on every other dice site. Notice that despite thousands of players, only a very low amount so far complained about such long loss streaks. These are the few very unlucky ones. Results are provably fair. Any player can verify that their results are fair as well as check the entire database of bets and see that the house edge indeed closely follows 1%.

days ago said "expect big changes" ... change the lower limit are two lines of code (if the program is well done), but ...

Would it be possible for you guys to allow "0" bets? Either that or allowing single satoshi betting? Ideally both would be possible.
It would probably drive more traffic (money) to the site as well. These features are available at a few other dice sites.
Any way this would be possible over at Coinroll??
