Qtum

The QTUM platform and its namesake cryptocurrency go for bringing the best of both worlds with both the Bitcoin and Ethereum, focusing on making their features more accessible to businesses and organizations. The aim is to allow for automation of smart contract development, faster creation of custom coins and drastic reduction in related fees.
The QTUM was launched in Singapore in 2017 as a hybrid platform combining the strengths of Bitcoin and Ethereum. Patrick Dai, Neil Mahi and Jordan Earls launched the project which should enable faster programming of smart contracts combined with the stability features offered by the Bitcoin blockchain.
Faster creation and deployment of smart contracts should be made possible with the help of contract templates, pre-built contracts and accessible tools. In early 2019, the platform was home to the first proper atomic cross-chain swap with Bitcoin on the mainnet.
