Okay, I noticed the following:

You will notice that the "salt" parameter is optional. The reason for this is that during a live roll generation, the salt is derived from a millisecond-accurate system clock time which is enough to randomize it as an input.

So I had to have a look. Basically: you should never use time within a provably fair implementation. It automatically makes the provably fair implementation 100% not provably fair

The reason is simple: it's extremely easy for you, as site, to do this:
- If winning bet > add millisecond.
There is no way for the player to know if a millisecond has been added or not. Therefor it's extremely easy for you to cheat players and therefor the Rubies bet provably fair implementation is not provably fair. Of course I am not claiming you are doing this and I personally would trust you guys. But provably fair is all about not having to trust the site owners.


(The "bitcoin provably fair implementation" is basically just questionable. RHavar and I had a discussion about it before and he finds it very unlikely to be really exploitable by the site and I kinda agree with that. But the Rubies provably fair implementation is really just wrong.)


Sure, I will PM my skype name.

On a side note, what's the high-level motivation for wanting to use a timestamp? The client adds their bit of randomness with the client-seed, and the server already picks the server-seed and server-secret, so why do they also need a timestamp?

Even though many people hate MP's provably fair system, I think it makes a lot of sense as it's designed to be machine-auditable, and it's the absolute simplest way to do that. But since it seems rubies is user-facing, I'd strongly suggest to just copy JD's scheme, it's definitely the most user-friendly and human auditable.

Also seems my BB account had 1200 rubies in it, which like a true gambler I promptly lost. It's funny, because I did the same thing with clams when they first launched. I should stick to running casinos

I have forwarded your post to Lobos, he had to sleep though and will connect with you to get this changed. Obviously, we have zero intention of giving coins to the Bitcoin/Altcoin population only to cheat them, but there is room for improvement and I agree.

Check your pm's from ~50 days ago I didn't hear back from you on this.

If I may ask, why did you go for the Rubies angle? Do you think it makes the gambling easier or more complex? I never understand why sites go for a Alt coin alternative and not stay with purely Bitcoin? Sorry if I ask a misguided question, but I am intrigued by these moves.

Thanks for any feedback in advance. ^smile^

You know, you're right. An the truth is, I never looked at it from that point of view ... I guess I just don't have the cheater/scammer mindset :-)

I sent you a skype contact request, lets talk about some technical details and then get this fixed.

Hello,


Good questions, I don't want to bore people with all the details but when I first started working on the concept of Rubies and "Bet-Mining" it was back in August of last year. I made a post many months ago hinting about it, the whole premise for this was that "No player walks away empty handed". I wanted to see if there was a way we could have people play on BetterBets and even if they lost their BTC during a betting session they would still have something to take home with them, thus Rubies was born from this.

It has evolved many times and been reworked to become a top ten altcoin so that those who were loyal to Rubies would be extremely happy when they earned them. This is literally only the beginning though, and this coin will be far greater than it's early distribution model in time. On March 1st we are launching the March Madness promotion to further strengthen the foundation for Rubies, and you will see much of the work that has been done behind the scenes to make it amazing for everyone.

-Bjorn

edit:March Madness is going to show everyone we do not want to have Rubies centralized on our site, we are just the birthplace and one current business accepting it's usage. Keep this in mind as we show you what is coming soon!

This is just 1 more way for all of you to be involved with RBIES. Dont miss out

[Bitinity]

Do you have a plan to add rubies faucet on your site? I think it would be great to see rubies faucet, at least for some new players who have not own any rubies. Just in case it is possible, since you are using moneypot.

Hi Bitinity. Yes we have. It is a part of future versions to our site.
That said, and with the new model purpose by the MP team , which it will support alt-coins, them the adoption of rubies faucets will be a true reallity.


Keep playing at betterbets.io

Cheers!! ●‿●

March Madness is really cool however there could have been Multiple prizes if not like shopping cart as you always say

May be 2 extra prizes for runner ups will be a good deal !

[BetterBets.io]

Check the altcoin thread Taxmanmt5, and this is just the start Much more coming this month.

[Cyaren]

I'm going to deposit 0.01 BTC right now, it's my first time really depositing a legit amount. Hopefully all goes well!

[ranlo]

GL to those taking part in the March Madness event! For those that aren't aware, the rewards, on top of winning the grand prize are free Rubies. To help break it down a bit...

You get 3 Rubies for every 0.1 BTC in volume
1 Ruby is currently worth 0.00015+
That means 0.00045 per 0.1 BTC in volume

BUT because of how Rubies are distributed, they are already getting more and more rare, so the price is likely to go up. Or you can use them for betting. Or you can sell them. All the while earning those, you're also shooting for the grand prize of 4 BTC.

(For those that aren't aware, if you bet 1 BTC at 1.02x, which is a 98.x% chance, that still counts as 1 BTC wagered towards the contest and means 30 Rubies are earned instantly, which would be around 0.0045 BTC)

Disclaimer: don't risk more than you can afford to lose. It's a game. Don't let it consume you, .
