Steem is a blockchain-based social media platform that allows users to create and share content while rewarding participants with cryptocurrency tokens called STEEM. The platform was created to provide a decentralized and censorship-resistant alternative to traditional social media platforms.
Steem operates on a delegated proof-of-stake (DPoS) consensus mechanism, where stakeholders have voting power in determining the platform's governance and content moderation. Users can earn STEEM tokens by posting and curating content, and these tokens can be converted into other cryptocurrencies or traded on various exchanges.
The Steem community comprises developers, content creators, investors, and users who are actively involved in the platform. Various decentralized applications (DApps) have been built on the Steem blockchain, allowing users to explore different types of content, such as blogging, video sharing, and gaming.
If the Steem Alliance is a recent development or a specific organization within the Steem community, I recommend conducting a search using up-to-date sources or reaching out to the Steem community directly for more information.
