Founded in 2016, Qtum is an open source, UTXO-based smart contract platform with a Proof of Stake (PoS) mechanism that features a Decentralized Governance Protocol (DGP).
The DGP protocol allows blockchain settings to be modified by making use of smart contracts. For example, the block size of Qtum can be increased without the need of a hard fork.
The DGP protocol can seamlessly work within existing blockchain infrastructure while also being able to incorporate any new technological breakthroughs that may come later. This all adds up to a lean, capable, and secure cryptocurrency created for out-of-the-box usability.
The developers of Qtum melded the core code of Bitcoin with the Ethereum Virtual Machine to create a cryptocurrency that is both highly secure and highly scalable. This means that businesses, users, and projects already running on the Ethereum protocol can easily make the switch to Qtum.
By offering smart contracts as a way to make processes more reliable, more secure, and more automatic, businesses can cut costs and streamline their economy when they use Qtum.
