Stacks is a new Internet for distributed applications, equipped with a complete set of open source development tools to build and guide the distributed application and protocol ecosystem. Users have their own data, and the browser is everything they need to start. Stacks is the "Google" of the blockchain. The architecture is divided into three layers: blockchain bottom layer - peer-to-peer network - data layer. Stacks' business model is very clear. Its goal is to become a blockchain browser. On this browser, users can create basic todo applications and build single page JavaScript applications. Stacks (once called blockstack) attempts to empower a new type of decentralized Internet, which can enable users to better control their data and make it more difficult to review content. It has attributes such as "built-in privacy", in which data (such as photos, messages, health records) in the stacks application is encrypted by default. Apps will not be able to view, access, or track your activities. Users, not applications, have 100% of all data. In addition, users are free to move their data, conduct transactions and transfer your assets - without any application or company license. Stacks' smart contracts, based on its programming language clarity, can create, own and trade new digital assets, such as tokens and digital collections. By using the stacks application, creators can also share the value they create. Stacks use a hybrid consensus mechanism, which is called transmission proof (POX).
