Steem is based on the Smart Media Tokens (SMT) protocol, developed by Steemit. As of December 2017, CoinMarketCap.com listed Steem with a $475 million market capitalization, and ranked Steem tokens 32nd of 1,358 cryptocurrencies. User actions, such as upvoting facilitates Steem's Proof-of-Brain algorithm, which also factors in the Steem Power a user holds, to provide incentives for content creators and the community by transferring small amounts of the Steem token currency.[6]
Steem began with a highly inflationary supply model, doubling roughly every year.[5]
On July 4, 2016, Steemit, Inc. launched Steemit, a social media with virtual currency rewards that runs over the Steem blockchain. On July 14, 2016, Steemit announced on their website that they were hacked. The attack, according to them, has compromised about 260 accounts. A little less than US$ 85,000 worth of Steem Dollars and Steem are reported to have been taken by the attackers.[8]
Unlike most digital currencies which are difficult to access for the majority of the world without any money to invest, Steem removes the friction for the average person to join in the cryptocurrency world by allowing earnings via posting without needing to buy in first.[9]
