Qtum has been created by forking Bitcoin’s source code and adding various custom modules to integrate the EVM. Qtum proposes a series of innovations in blockchain technology and implementation: - a UTXO model based smart contract platform - a flexible consensus (Proof-of-Stake) mechanism for public and permissioned chains - the Master Contract concept, identity management through smart contracts. Qtum is secured by the Proof-of-Stake 3.0 (POS 3.0) consensus protocol.

What is Qtum
Qtum is an open sourced public blockchain platform, leveraging the security of UTXO while enabling multiple virtual machines including EVM and the revolutionary x86 VM. Qtum is PoS based and boasts a Decentralized Governance Protocol (DGP) allowing specific blockchain settings to be modified by making use of smart contracts. For instance, the block size of Qtum can be increased without the need of a hard fork.
Blockchain-enabled smart contracts that employ proof-ofstake validation for transactions, promise significant performance advantages compared to proof-of-work solutions. For broad industry adoption, other important requirements must be met in addition. For example, stable backwards-compatible smart-contract systems must automate cross-organizational information-logistics orchestration with lite mobile wallets that support simple payment verification (SPV) techniques. The currently leading smart-contract solution Ethereum, uses computationally expensive proof-of-work validation, is expected to hard-fork multiple times in the future and requires downloading the entire blockchain. Consequently, Ethereum smart contracts have limited utility and lack formal semantics, which is a security issue.
We discuss the Qtum utility advantages compared to the Ethereum alternative and present Qtum smart-contract future development plans for industrycases applications.

Total supply is 100M coins and the inflation rate is about 1% per year (this may be slightly changed when they release the mainnet, but the inflation rate will be kept low). Distribution: - 80% of the tokens will be eventually allocated the community; - 20% will be allocated to the foundation initiator, early backers, and the development team. Ownership of tokens refers to the right to use the Qtum DApps and the blockchain.
