Title: LuckyBit bet verifier - Check that your bets are 100% provably fair! Post by: LuckyBitSupport on January 21, 2014, 10:27:30 PM LuckyBit bet verifier LuckyBit - http://luckyb.it More and more bitcoin gambling sites are being published, and often enough it's extremely hard to verify the claims about them being provably fair. In order to make this step easier for LuckyBit, we wrote a "bet verifier" that allows players to verify that their bets are 100% provably fair. What is LuckyBit? Quote from: BitcoinReviewer LuckyBit is a Bitcoin gambling website that resembles the well-known game called Plinko. Bets take place “on the blockchain”, meaning that there is no need to create an account. Source: http://bitcoinreviewer.com/luckybit-review/To play, all you must do is send BTC to a chosen address to place your bet, and the Bitcoin will fall into a designated area where you have a chance at winning up to 999x your initial bet. A neat feature is that you never lose all of your bet either. The minimum amount you’ll receive back from a bet is 0.2x your initial bet. This is an attractive feature, as you will never completely lose your initial bet. This is the main thread for LuckyBit: https://bitcointalk.org/index.php?topic=322158.0 How does this work? The bet verifier allows users to verify that their bets are 100% provably fair. Given a transaction id, the verifier computes locally the result of a bet. It uses trusted 3rd-party sources (http://blockchain.info) for this computation so that you can be sure that everything is 100% correct. The verifier then compares the locally computed outcome to the bet as processed by LuckyBit, using the LuckyBit API. It shows every step of this computation and warns the user when something is wrong. Example output: http://luckyb.it/files/lb-bet-verifier-screenshot.png Why should I trust this? It's open source - go read the code!
