QTUM is a blockchain platform that combines the best of both worlds - the security and reliability of Bitcoin's blockchain and the flexibility and smart contract capabilities of Ethereum's blockchain. It was created in 2016 by a team of developers led by Patrick Dai, who had previously worked on the Ethereum project. QTUM uses a proof-of-stake consensus mechanism, which means that instead of miners, validators are chosen based on the amount of QTUM they hold and stake. This makes the network more energy-efficient and less prone to centralization. QTUM also supports the development of decentralized applications (dApps) and smart contracts, which can be written in popular programming languages such as Solidity and C++. The platform has gained popularity among businesses and enterprises looking to leverage blockchain technology for their operations.

QTUM's native cryptocurrency is also called QTUM and is used to pay for transaction fees and smart contract execution on the platform. It has a total supply of 100 million tokens, with a circulating supply of around 96 million tokens. QTUM can be bought and sold on various cryptocurrency exchanges and can also be stored in QTUM-compatible wallets. The team behind QTUM has been actively working on improving the platform's scalability and interoperability with other blockchains. They have also partnered with several companies and organizations to promote the adoption of QTUM and blockchain technology in general. Overall, QTUM is a promising project that combines the best features of Bitcoin and Ethereum and has the potential to become a leading blockchain platform in the future.
