Hive is a decentralized content network, powered by Delegated-Proof-of-Stake (DPoS) consensus algorithm.
Hive was forked from the Steem blockchain, after the Tron Foundation acquired Steem and gained control of the company's funds in STEEM, which made up approximately 80% of the total STEEM supply. The fork is aimed to cope with the risks of centralization brought by this acquisition, as pro-Tron STEEM addresses were blacklisted and would not receive the HIVE token airdrop.
The Decentralized Hive Fund ("DHF") allows users to suggest proposals, fund those proposals, and cast a vote for their preferred changes. The Fund is set up so that no single actor can have control over major changes.
The Hive platform offers many functionalities similar to those of Steem. The platform has two tokens: Hive (HIVE) and Hive-backed dollars (HBD). HIVE is used for unlocking a variety of different functionalities the platform offers, which HBD is used mainly as a method for rewards.
