Steem Overview.

Steem is a blockchain-based social media and content platform that allows users to create, share and curate content while earning rewards in the form of cryptocurrency called STEEM. It was launched in March 2016 by Ned Scott and Dan Larimer.

The Steem platform is designed to reward users for their contributions to the platform, such as creating content, commenting, and voting on content. Users can earn STEEM tokens for their activities on the platform, and these tokens can be traded on cryptocurrency exchanges for other cryptocurrencies or fiat currencies.

Steem uses a consensus algorithm called Delegated Proof of Stake (DPoS), which allows users to vote for witnesses who are responsible for validating transactions on the blockchain. The witnesses with the most votes are selected to validate transactions, and they are rewarded with STEEM tokens for their efforts.

Steem has been used to power a number of decentralized applications, including blogging platforms, video-sharing platforms, and social networks. Some of the most popular applications built on Steem include Steemit, DTube, and Busy.org.

Overall, Steem aims to provide a decentralized and censorship-resistant platform for content creators to share their work and earn rewards for their contributions.
