<p>Online payments have been one of the major applications of the web since the rise of usage of the internet by the general public in the early 1990s – earlier implementations were naturally a lot cruder. Later on, superior payment systems like PayPal and Stripe came along and offered developers ways to facilitate payments.</p>
<p>Another huge wave followed after that – cryptocurrency. Many people had been trying to create popular digital currencies for years – most notably was Nick Szabo with his early efforts in the 1990s. In 2009, blockchain-based currencies were create and later Ethereum, which comes out of the box with smart contracts, was created. Not only is the Ethereum platform advanced, it is also versatile in that it comes with Web3 that can be injected into a web application’s instance to facilitate Ethereum transactions.</p>
<p>Javascript has become a mature language that is capable of doing things that had long been ascribed to compiled programming languages – this maturity has given leeway to create better products.</p>
<p>WordPress is now running on 30% of all websites – in a way, it has become a kind of web operating system. This means that it has become unavoidable and thinking about creating new products and dedicated implementations of existing products for WordPress is imperative.</p>
<p>The combination of better payments technology, cryptocurrencies, mature Javascript and a web dominated by a very powerful WordPress was fertile soil to create Spreebie Bartner – a completely new paradigm in online payment.</p>
<p>This plugin requires Metamask to work.</p>
<p>THIRD PARTY SERVICE NOTE: When making donations to the author of this plugin, a third party service called Firebase (https://firebase.google.com/) is used to store donator names and emails. A donator can choose to donate anonymously so that their name and email are not stored. This third party service on this plugin ONLY works with donations to the author – the rest of the plugin functions without it.</p>
<p>Another third party service used is CoinMarketCap (https://api.coinmarketcap.com) – this is used to get Ethereum price information for different currencies. There is no storage that happens with this service.</p>
