Hi everyone. I'm happy to release Provably Fair, a browser extension that verifies provably fair bets. The game seeds/nonce can either be entered manually or populated automatically when clicking the extension on a Stake.com bet verification page. It supports all games on Stake.com but I'd love to add support for more games and sites (let me know in the comments!).

Quick demo on Stake:



A longer demo on YouTube: https://www.youtube.com/watch?v=chAQkOZBTLs

My long term goal with this extension is to increase the adoption of bet verification and make it more widespread, especially among non technical players. To achieve this goal, it is crucial to reduce the friction of verifying bets and make it easy and understandable. For example, in the future, I'd like the extension to do automatically verify every bets in the background and automatically change client seeds to prevent a site from predicting game outcomes. It's not there yet, but it's on the roadmap!

The extension is built with Rust + WebAssembly (fast!) for the verification library code. The library code is open source and available on GitHub (as well as a command line utility): https://github.com/lucasholder/fair.

If you have no idea what provably fair is, I tried to do an ELI5 it here: https://fairdom.io/how-provably-fair-works

• Blackjack
• Hilo
• Baccarat
• Diamond Poker
• Dice Roll
• Limbo
• Plinko

I'm happy to answer question and feel free to request support for other sites/games.

Cheers,
Lucas

I noticed a lot of people sell prepaid virtual credit cards for Bitcoin in here. Anyone knows how the sellers go about making the cards? Doesn't Visa/Mastercard have KYC rules? And isn't it very expensive to become a credit card issuer?

Thanks.

I slightly improved the spreadsheet form from FAQ: Everything you need to know about forum 'activity, account ranks and merit by displaying a "next period" cell so that you don't have to manually go through the list of dates to figure it out. Thought I'd share it here since I'm not sure who owns the original spreadsheet and can't comment on the FAQ post.

Does such a prepaid/reloadable card issuer exist and what are their KYC requirements? Almost all solutions I found involved US citizenship and providing a US social security number.

Is there a page like https://bitcointalk.org/index.php?action=unread but that lists newly created topics instead (e.g. lists topics by decreasing creation date order)? Otherwise, I guess that would be a feature request. It would give visibility to newer topics which are sometimes quickly buried by active topics that are older.

I noticed a lot of people immediately post a "Reserved" reply after submitting a new topic. What is the purpose of that?

What was Satoshi's reasoning behind halving the mining reward over time? Why did he not instead choose to do it in reverse and double the reward at each "doubling" (up to 50 BTC and then 0 - same total mined reward but distributed in reverse order)?

It seems that increasing the mining reward over time would have made more sense for at least two reasons:

1) It doesn't favor early adopters.

2) As mining difficulty rises, so does the cost of mining and therefore, the reward should be higher as well. Of course the rising price of BTC compensates for that but as we've seen recently, the price doesn't necessarily grow all the time.

Discuss.
