Steem is a social blockchain protocol designed to incentivize the participation and the sharing of content in decentralized networks.
Steem was the second Delegated Proof-of-Stake (DPoS) network created by Dan Larimer, following BitShares and preceding EOS.
Featuring free transactions, the Steem blockchain allows for micro-transactions, upvoting, and other content curation actions to occur with little friction.
In Steem, witnesses are selected by stakers who receive voting power for every STEEM they stake. Afterward, witnesses produce blocks for the chain.
