Competition is over, here are the results:

was very close to qualify,around 0.02 profit
then started to bet higher stakes...
didn't qualify,lost my balance,better luck next time

I've used the API to create a script that can notify people using the Join app for Android when a bet that wins or loses over a certain amount is made. If anybody else uses this app and is interested, I could consider opening this up to anybody that wanted to receive notifications.

I've been thinking, one of the biggest problems with provable fairness is how often people simply don't use it. This is often because of the extra steps required to make sure everything is fair. As I'm sure a lot of you know by now, I like to make sure that everybody has the best experience possible. What if we had a userscript, or chrome extension that automatically did this for us?

One of the biggest holes in nearly every provably fair scheme is the hash of the server seed. Extremely often, it's just not written down/copied anywhere. Most sites don't show you the hash until you open a window or go to a page that displays it. What then? If the site knows that you haven't looked at the hash, then you wouldn't be able to tell whether or not the server seed they revealed to you was the one they were using. Now of course, this isn't perfect, as the site would have no way to guarantee that you won't look at the server seed hash halfway through playing, but it's still possible. The point of provable fairness is to remove all doubt that the site could be altering results.

I propose a chrome extension to do this, as I believe it has the lowest "cost of entry". All a user has to do is simply click the install button and they're protected. A userscript requires too much technical knowledge for most people to set up, although it could work cross-browser. I believe that anybody privacy-conscious enough to use other browsers is also smart enough to copy down their server seed hash.

The extension could be able to do the following, all behind-the-scenes:

• Record new server seed hashes as they are generated, to prevent sites from changing them later and storing them securely in chrome.storage where the website and other extensions can't touch them. (This has the added benefit of being able to sync between different chrome browsers).
• Instantaneously verify all bets made in the past as soon as a new seed is in use and the previous one revealed.
• (Fluff) Have a counter of all bets made by the user that have been verified when you click on the extension icon

Of course, the potential for a malignant extension here is huge. A bad extension that has access to the page would be able to withdraw a user's entire balance to an attacker's address. Such an extension would have to be open-source so that anybody could examine it and make sure nothing bad is going on behind-the-scenes.

I'd love to hear people's thoughts about this, as well as hearing from anybody that doesn't use chrome as their browser so I can get a handle on how many people would be affected before I think about working on this. The great thing about a chrome extension is that it could support any number of websites, without the user needing to add additional extensions or such.

Thanks!

Sounds like pretty good to me. I mean we never get time to verify each of our bets also don't get to know when server seed hash is changed.

Yahoo is one of the best "hitters"/earners on dice that i have ever seen!
Big congrats to him,he has the magic touch...

Hi,

it sounds great, but don't you think people are sceptical when installing extensions related to anything "Bitcoin"? At one hand an extension like this could protect people from one threat, but on the other hand (as you noted) they now would have trust the extension too, because with an extension can open ways for huuuuge abuses in general. An extension being open-source doesn't help much because you get extensions from Stores, not directly from repositories.

I have another idea that could possibly work and could apply to more dice sites, not just YD - but it has to be independently develped, not by us. A type of a "watchdog site" - it gets all seeds from the server and monitors for any changes. It could also allow verification, or even verify all bets live, but I am not sure about it. IMHO watching seeds should be enough to monitor  the site, plus on-demand bet verification.

This can be all done using the API for YOLOdice, I am not sure about other sites. But it would be possible to reveal if a site cheats pretty easily. Plus, the results would be public, so any site that tries to cheat risks a lot.

It's just an idea, but what do you think?

Ethan, do you think that you could start tracking investment profit independent of each individual investment? I ask this because right now if it's say the day after commission was taken and my investment is down 3% since commission was taken, I can't close the investment before I get that 3% back otherwise I'll get commissioned on the same profits twice. When the commission is already a pretty large 35% this can really hurt so it essentially traps your money in the site. Will you consider changing this?

EDIT: Also, when will the site support SegWit addresses?

Hi,

thanks for the ideas. Right now the commission is indeed linked to individual investments' profit, I did not think it would be a large issue at the time I designed it like this. I'll think about it, but honestly it would require a pretty serious code rewrite.

Regarding segwit addresses - I am ready. The thing is that Bitcoin Core wallet has pretty poor support for Segwit, it's not that easy to go full-segwit. See my question here: https://bitcointalk.org/index.php?topic=2107760.0 - for some reason the developers coded Segwit as part of the protocol, but completely neglected making it actually useful.

Enabling Segwit would also suck for privacy - if YD was the only wallet that sends Segwit transactions, it would be pretty strange.

Other than that, I have already set some deposit addresses (mostly mine) to Segwit addresses and now I am testing it. If all goes well, I might enable Segwit pretty soon.

Cheers,
Ethan

I'm not worried about the privacy aspect because I believe that will be a short-term thing once more people start using segwit. Maybe you could give users a toggle between deposit addresses being P2WPKH or P2PKH. (I know that would be more work but if people are worried about privacy it might be nice). Plus, segwit addresses should save the site money on fees.

As for the investments, maybe just add it to the trello board as a to-do sometime in the future when there's time to work on it. It's not that serious of an issue I suppose but being charged 35% on the same profits twice or more if you close the investment in the red is pretty rough.

Hey all. Hey ethan_nx I was wondering.

How difficult would it to be to convert Yolodice into an Android app ? Not just a strait copy of the site to an app I mean an actual Yolodice app with all the features of the site in it. Would this be something to do ? I just wonder how much interest such an app would bring, because Yolodice is doing new things all the time and the first to do them too so why not the first to have a fully functioning dice casino app ? You could add noises to the dice maybe even an animation of the roll. The big thing would be to have the app for regular users to make it easier to chat, so think of it as a Yolodice chat app too.  Just an idea I thought I would present.

I dont like this idea.
I have tried so many applications which regards with gambling and they are all not looking good.
Bugs are always there and there could be ways that it could be hacked.
A browser based would still be the perfect one. The bugs are easily fixed unlike with android applications.

I use the website on my phone very often. The site is heavily optimized for mobile devices and is just as good of an experience as you'd get with a first-party app. You should try it out.

Enabling Segwit would also suck for privacy - if YD was the only wallet that sends Segwit transactions, it would be pretty strange.

I don't think it would have any significant effect on privacy, since any online wallet can be quickly checked with some tools like wallet explorer.

Here's a hot wallet of YOLOdice for example: https://www.walletexplorer.com/wallet/000379e0185a9c23

Improving privacy on the side of a service would  require using unique address for every deposit or routing all transactions through mixer. But it will all be expensive and inconvenient for users, so it should be mainly their responsibility to protect their privacy.

I was wondering what the results are for investors in Yolodice. Anyone willing to share experiences?

Just check this topic: https://bitcointalk.org/index.php?topic=1573091.0 There are a lot of user experience about investing on gambling sites, also on YOLOdice.
