What steemit is . "Explained"

Steemit markets itself as a blockchain-based social media network and it’s built on top of Steem, a complete, decentralized social crypto-economy.

Steemit is built on the Steem blockchain— this is similar to the Bitcoin blockchain, but is separate from it. Another name for blockchains is distributed ledger technology (DLT). This means that it’s a distributed database — lots of people hold copies of it that talk to each other in order to stay up to date. Records are added to the blockchain in sequential order. These records, or blocks, once added to the database, or chain, can not be changed. They are immutable — read-only.

Steem is peer-to-peer. There is no central control. The developers, however, maintain huge influence over Steem’s course.

Steem is like Bitcoin, Ethereum and other cryptocurrencies, but is actually a lot more.

Whereas Bitcoin miners earn block rewards by solving difficult math problems — called objective proof of work — Steem rewards users for subjective proof of work: the creation and curation (upvoting and flagging) of content.

This is unique. And it opens up a lot of possibilities for you to earn cryptocurrency, most notably through content creation and curation.
