JSEcoin is a consumer-focused web platform built on top of a browser mined blockchain. Their ambition is to create an energy efficient cryptocurrency mined by webmasters which is adopted globally by mainstream users. It is possible to carry out SHA256 and other encryption in a standard web browser or on a mobile device. By embedding a javascript snippet on a website all visitors to the website could carry out the hashing encryption process, which when combined at scale could replace the role of the miners. Website owners would then be rewarded by the distribution of the currency. We have estimated 1 in 15 people either own or have access to a website which provides a large distribution and potential client base.
