A core feature of Steemit is its reward system. As a blockchain-
based social media network that issues its own cryptocurrencies,
Steemit leverages its native cryptocurrencies to incentivize authors
and curators of posts for rewarding contributors to the platform,
who either create good contents or screen out good contents. In this
subsection, we theoretically analyze the reward system in Steemit
and study the factors correlated with rewards earned by authors and
curators. We also jointly investigate the value-transfer operations
and vote operations to understand if the reward system is being
misused by Steemit users, such as buying votes from bots to promote
their posts for the purpose of earning higher profit. Such misuse
may deviate from the original intended goal of the Steemit reward
system.
