Having previously announced plans to meld the Bitcoin protocol with Ethereum technology, they are now launching the first ‘Proof-of-Stake’ smart contracts platform. As a combination of Bitcoin Core, Proof-of-Stake (PoS) and the Ethereum Virtual Machine (EVM), the end product of Qtum Blockchain is Qtum Core, which will allow smart contracts to execute on a PoS consensus model. (Note: The open source project integrates the EVM with Bitcoin’s UTXO model and aims to provide smart contracts to businesses worldwide). “All current ethereum projects can be easily ported to Qtum platform since the Qtum platform is compatible with EVM,” explained John Scianna at Qtum, who has worked for several startups included CoinPip and been following bitcoin since 2012. These problems span the lack of business-oriented smart contracts in that the current smart contract platforms are mainly based on 'Proof-of-Work' (PoW).
