Nimiq is a frictionless peer-to-peer payment protocol for the World Wide Web. It is a third-generation Blockchain protocol combining elements of Bitcoin and Ethereum, streamlined for the web platform. And without a doubt, it is open source and fully decentralized. Browsers are first-class citizens in the Nimiq distributed network. They are able to establish consensus with the network, and enable true peer-to-peer payments from within, all without a trusted third party. In comparison to conventional cryptocurrencies, this browser-first approach lowers barriers of entry by orders of magnitudes for developers, customers and merchants.
