Steem blockchain gal
Steem é unha base de datos na BlockChain coa cal está conectada a Rede Social Steemit.
Creouse como unha Base de dados na blockchain, de código aberto e acceso público para permitir a construccón de comunidades e a interacción social, proporcionando recompensas en [tokens steem]
No seu lanzamento, o Libro Branco Steem, declarabase como a primeira criptomoeda que tenta premiar con precisión e transparencia a un número ilimitado de persoas que fan contribucións subxectivas á súa comunidade.
A plataforma Steem está deseñada para sortear as principais barreiras para a adopción e monetización dunha economía baseada nos medios sociais. Mimetiza as mesmas técnicas utilizadas para facer grandes plataformas de redes sociais (como Facebook, Reddit e Medium) para arrincar unha criptocurrency exitosa tamén chamada Steem. (ver Tokens Steem ).
Ned Scott_Gal, cofundador da plataforma, en Maio do 2016, antes do lanzamento oficial e ainda en fase beta test, Steem e [Steemit] ) o sitio de medios sociais que corre sobre Steem, desvelaba a CoinReport a orixinalidade da plataforma: Os posts, comentarios e votos asentabanse directamente sobre a base de datos da Blockchain Steem.
Esta sistemática permitiría que Steem proveitarase de varias camiños novos e diferentes (e inexplorados ainda),que incluían a atribución baseada na blockchain, as recompensas de contido baseadas na blockchain e a reputación baseada na blockchain
Os fundadores desexan ver todo o seu potencial desenvolto e o seu obxectivo non é só crear unha vibrante plataforma de redes sociais con Steemit, senón ver que os empresarios de diferentes ámbitos de vida aproveitan e integran Steem como unha plataforma editorial de código aberto.

Censura e atribución baseada na BlockChain
Toda actividade das usuarias de Steemit son grabadas publicamente na blockchain, e poden ser verificadas publicamente. Os sitios webs individuais e Aplicacións Steemit poden restrinxir o acceso a determiñados contidos ou censurar contido no seu "site" particular, mais o contido publicado na blockchain é inherentemente transmitido, e os espellos (mirrors) arredor de todo o mundo continuarán a facelo dispoñible.
Baixo un Medio Social baseado na BlockChain, unha creadora ou autora sempre poderá apuntar a un rexistro público -e inmutable- e a unha marca de tempo mostrando a proba-certificación da súa orixe. Nunha circunstancia onde unha creadora quixera dirixir aos que partillaron contidos da súa autoría sen permiso nin atribución, os rexistros baseados na blockchain proveen a proba de que o contido foi publicado por unha usuaria en particular en un intre determiñado. No futuro, a atribución baseada na blockchain pode ser recoñecida polos governos para demostrar autenticidade e pode ser admitida como proba nos tribunais, todo o cal pode proporcionar ás autoras notable control sobre seu traballo.
A publicación de calquera traballo na blockchain, asegurará cando menos,a proba de anticipación no tempo.
Performance, Scalability and Consensus Algorithm
The Steem platform is built upon Graphene, the same technology that powers BitShares, another blockchain network created by Dan Larimer, also a co-founder of Steem and Steemit with Ned Scott. This technology has been demonstrated sustaining over 1,000 transactions per second on a distributed test network and can easily scale to 10,000 or more. Steem is capable of handling a larger userbase than Reddit.
With Steem, block production is done in rounds. Each round 21 witnesses are selected to create and sign blocks of transactions. Nineteen (19) of these witnesses are selected by approval voting, one is selected by a computational proof-of-work, and one is timeshared by every witness that didn’t make it into the top 19 proportional to their total votes. The 21 active witnesses are shuffled every round to prevent any one witness from constantly ignoring blocks produced by the same witness placed before.
Because the active witnesses are known in advance, Steem is able to schedule witnesses to produce blocks every 3 seconds. Witnesses synchronize their block production via the NTP protocol. A variation of this algorithm has been in use by the BitShares network for over a year where it has been proven to be reliable.
Steem Ecosystem
In August 2016 Ned Scott declared to Coindesk that entrepreneurs and developers have already created 50 different tools over the Steem blockchain network, such as Catch a Whale (which tracks where whales have recently voted) and SteemMarket (which lets users buy, sell and rent goods with Steem). He said: "The people showing up to use this are going directly to the blockchain. We don't have the authority to tell them not to. In fact, we implore it. What we set out to do is build an ecosystem and that’s exactly what’s happening." In February 2017, there were 118 different Steem apps listed on the site SteemTools. Read more on Steem Ecosystem.
