Qtum is the foremost toolkit for building trusted decentralized applications, suited for real-world, business oriented use cases. Its hybrid nature, in combination with a first-of-its-kind PoS consensus protocol, allows Qtum applications to be compatible with major blockchain ecosystems while providing native support for mobile devices and IoT appliances.
To stake QTUM coins it is recommended to run the official Qtum Core wallet with an entire copy of the blockchain on your Computer or a Virtual Private Server (VPS). To get the highest possible rewards, please make sure to stay online 24/7 and keep the wallet unlocked for staking only.
The individual reward depends on the Block Reward, Block Time, Daily Network Rewards and Total Staked.
Every block one staker is randomly selected whereas 1 staked coin counts as one “lottery ticket”. The selected staker has the right to create a new block and broadcast it to the network. He then receives the block reward and the fees of all transactions successfully included in this block.
Staking Qtum is safe as long you protect your private keys. There is no risk of slashing.
