Steem is a blockchain-based platform designed to empower content creators and curators by rewarding their contributions with cryptocurrency. Launched on 24 March 2016, the Steem blockchain introduced a decentralised reward mechanism for online content, aiming to solve monetisation challenges in social media platforms.

The project integrates blockchain technology with social media concepts, offering a transparent and censorship-resistant system where content creators can receive rewards directly from the network's protocol without relying on traditional advertising models. Its primary use case revolves around social media applications and decentralised communities where users are incentivised to post, comment, and curate content.

Key Features of the Steem Project:

• Delegated Proof of Stake (DPoS): Steem uses a consensus mechanism where block producers, called witnesses, are elected by token holders, enabling faster block production and scalability.
• Fee-Free Transactions: The platform eliminates transaction fees by using a bandwidth allocation system based on token holdings.
• Decentralised Content Hosting: Posts, comments, and voting data are permanently stored on the blockchain, making it resistant to censorship.
• Primary Application: The most well-known application built on Steem is Steemit, a decentralised social media platform where users can earn cryptocurrency for creating and curating content.

Token Ecosystem on Steem: The Steem blockchain operates a three-token model designed to support content monetisation, governance, and economic stability:

• STEEM: The primary token of the blockchain, used for rewards and liquidity.
• Steem Power (SP): A vested token representing long-term commitment to the platform. Holding SP increases voting influence and governance rights. SP is locked for a 13-week vesting period and cannot be transferred directly.
• Steem Dollars (SBD): A stablecoin designed to maintain a peg to the US dollar, providing predictable payouts for content rewards. SBD can be converted to STEEM over a 3.5-day period.

STEEM is the native cryptocurrency of the Steem blockchain, serving as the fundamental unit of account for the entire ecosystem. It plays a central role in rewarding participants who contribute to the network through content creation, curation, and platform engagement.

As the core digital asset on the Steem blockchain, STEEM is essential for all economic activity within the platform. It functions as the primary medium for distributing rewards and facilitating transactions across the network.

STEEM is a liquid and transferable token, which means it can be traded on exchanges, sent directly between users, and used for payments without restrictions. Its liquidity ensures that users can easily exchange it for other cryptocurrencies or fiat currencies.

STEEM also serves as the base token for conversions within the Steem ecosystem. It can be converted into Steem Power (SP), a vested token used for staking and increasing voting influence, or into Steem Dollars (SBD), a stablecoin designed for more predictable payouts.

The STEEM token has multiple utilities within the Steem blockchain ecosystem, primarily linked to incentivising user participation and supporting the network's economy.

• Content Rewards: STEEM is awarded to users who create and curate content on platforms like Steemit and rewards are distributed from the reward pool based on community voting, where higher engagement and upvotes result in larger payouts.

• Peer-to-Peer Transactions: STEEM can be transferred between users instantly and without transaction fees. The platform's zero-fee model makes it ideal for microtransactions and frequent interactions.

• Conversion into Steem Power (SP): Users can stake STEEM by converting it into Steem Power (SP). SP increases a user’s influence on content rewards and participation in governance decisions and also accrues staking rewards over time.

• Conversion into Steem Dollars (SBD): STEEM can be converted into Steem Dollars (SBD), which is intended to be a stablecoin pegged to the US dollar. (However, in practice, SBD has often experienced significant price volatility, deviating from its intended $1 peg. As a result, it may not consistently provide the stability expected of a typical stablecoin, though it remains part of the platform's reward system for more predictable payouts.)

• Trading and Liquidity: STEEM is a liquid asset that can be traded on multiple cryptocurrency exchanges. It can be converted back into fiat currencies or other digital assets, providing liquidity for holders.

Steem was co-founded by Ned Scott and Dan Larimer. The blockchain was officially launched on 24 March 2016, with its initial announcement made on Bitcointalk.org a day earlier.

• Dan Larimer: A blockchain engineer known for developing BitShares and later EOS. He served as the Chief Technology Officer (CTO) of Steemit Inc. before leaving in 2017.
• Ned Scott: The co-founder who focused on the business development and marketing aspects of the platform.
