Steem is a blockchain-based platform that rewards users for creating and curating content. Unlike traditional social media companies, Steem supports its users by paying them in cryptocurrencies for their contributions. The platform is non-custodial, decentralized, and secure, and is based on the principle that those who contribute to a venture should be paid by the owners. Steem uses delegated proof-of-stake to increase transaction speed and scalability, and distributes its tokens (STEEM) through a rewards pool rather than mining. The platform also offers Steem Dollars (SBD) and Steem Power (SP) as additional cryptocurrencies. Steem can be purchased through various crypto exchanges and converted to local currencies.
