The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Decentralized computing Confidence: 89% Arrow up

Decentralized computing is the allocation of resources, both hardware and software, to each individual workstation, or office location.

In contrast, centralized computing exists when the majority of functions are carried out, or obtained from a remote centralized location.

Decentralized computing is a trend in modern-day business environments.

This is the opposite of centralized computing, which was prevalent during the early days of computers.

Blockstack Confidence: 86% Arrow up

Blockstack is the first implementation of a decentralized DNS system on top of the Bitcoin blockchain.

It combines DNS functionality with public key infrastructure and is primarily meant to be used by new blockchain applications.

Blockstack is being developed by a group of engineers and researchers coming from both industry and academia and is released as open-source.

Other systems like Namecoin have implemented decentralized DNS using blockchains earlier by using blockchains other than Bitcoin.

Blockstack became operational on the Bitcoin blockchain in September 2015.

As of March 2016, Blockstack is the largest non-financial system using the Bitcoin blockchain by transaction volume.

Application software Confidence: 72% Arrow up

An application program (app or application for short) is a computer program designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user.

Examples of an application include a word processor, a spreadsheet, an accounting application, a web browser, a media player, an aeronautical flight simulator, a console game or a photo editor.

The collective noun application software refers to all applications collectively.

This contrasts with system software, which is mainly involved with running the computer.

Data Confidence: 71% Arrow up

Data (or) is a set of values of qualitative or quantitative variables.

An example of qualitative data would be an anthropologist's handwritten notes about his or her interviews with people of an Indigenous tribe.

Pieces of data are individual pieces of information.

While the concept of data is commonly associated with scientific research, data is collected by a huge range of organizations and institutions, including businesses (e.g., sales data, revenue, profits, stock price), governments (e.g., crime rates, unemployment rates, literacy rates) and non-governmental organizations (e.g., censuses of the number of homeless people by non-profit organizations).

Ecosystem Confidence: 70% Arrow up

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system.

These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows.

As ecosystems are defined by the network of interactions among organisms, and between organisms and their environment, they can be of any size but usually encompass specific, limited spaces (although some scientists say that the entire planet is an ecosystem).
