I am creating an online browser based Bitcoin miner. You can view an example of this site at [login to view URL] or [login to view URL] I am creating a user friendly website for users to learn and experience Bitcoins without having to download any software or purchase expensive equipment to do so. [login to view URL] Requirements; - PHP & MySQL – Based user system for Login & Signup, allows users to manage their accounts and also display their available Bitcoin balance. - Referral system allowing users to share a Public link and when user’s signup using that link the referee gets a small % of revenue generated by referral. - Java / Javascript – Browser based Bitcoin Miner – Allowing users to mine for Bitcoins and potentially Litecoins using the [login to view URL] web service. Some users cannot afford to build “Mining Rigs” nor do they want to do download programs. Having an online miner allows users to feel safe while using the user friendly design to experience the features. [login to view URL] -( Java Based Miner Source) - The website also acts as a Bitcoin Mining Pool Server which allows users to combine they’re mining outputs together to create a large chance to create a Bitcoin “block”. - [login to view URL] (Information about Pooled Mining) - Payout system – I get paid an overall percentage of 2% as a fee to keep this website and server running as I am paying costs out of pocket. Users will get 3% of their referrals earning and payout will be based on overall “shares” from each user. [login to view URL] - (Share Payout Information) - Bitcoins are based on anonymity, keeping the user registration simple is important as most users mining would not like anyone to know whom they are. The payouts based on shares will be paid to “workers” created by the user to identify they’re percentage in the overall calculations to find a block.
