What is Qtum?
Qtum is a blockchain technology-based public program which supports smart contracts and operates via PoS algorithm. The uniqueness of the coin is the mixture of Ethereum and Bitcoin characteristics together: it was built combining Bitcoin’s UTXO transaction method and smart contracts functions. This algorithm gives a bonus to the miners who validate transactions. The program uses a special protocol known as Decentralized Governance Protocol which supports making modification in special settings of a blockchain. For instance, if someone would like to increase the capacity of Qtum’s block, there’s no requirement of forking it. As of March 2019, Qtum’s market capitalization reached $191 million.
