Qtum (QTUM) Blockchain Platform - ICO Review, Rating and Details of Qtum ICO (Token Sale) - Rating: Not Rated

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.

Problems & Solutions

Blockchain-enabled smart contracts that employ proof-of-stake 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. The team fills the gap in the state of the art by presenting the Qtum smart-contract framework that aims for sociotechnical application suitability, the adoption of formalsemantics language expressiveness, and the provision of smart-contract template libraries for rapid best-practice industry deployment.

Features & Highlights

  • Decentralized Governance Protocol (DGP): Qtum’s Decentralized Governance Protocol (DGP) allows specific blockchain settings to be modified by making use of smart contracts.
  • Abstract Account Layer (AAL): Qtum’s Account Abstraction Layer decouples applications from the underlying protocol, maintaining the performance of the blockchain and lending the ability to add more smart contract capability in the future.
  • x86 Virtual Machine: Qtum’s x86 Virtual Machine will support C, C++, Rust, Python and other widely used programming languages, facilitating mainstream adoption of smart contract development.
  • Global Network: Qtum boasts the biggest PoS peer to peer network, with full-nodes only exceeded by the Ethereum and Bitcoin networks.
  • Wallet Ecosystem: There are a full spectrum of crypto wallets supporting Qtum, that meet the needs of different users.
  • Development resources: Qtum also provides mature development resources for blockchain and app development.
  • Transaction model: UTXO (Unspent Transaction Output) from bitcoin
  • Smart contract architecture: EVM (Ethereum Virtual Machine), adding the x86 virtual machine in 2019
  • Block size: 2 million bytes, scalable using on-chain DGP (Decentralized Governance Protocol) up to 32 million bytes
  • Average block spacing: 144 seconds
  • Smart contract token protocol: QRC20, based on Ethereum ERC20; QRC721 non-fungible tokens in development
  • Consensus algorithm: Proof of Stake, version 3.0, upgraded from Blackcoin
  • Theoretical maximum TPS (Transactions Per Second): 70 to 100. Much faster using Lightning Network and other Layer 2 technologies
  • Block reward: 4.0 QTUM through February 2022 (halved every 4 years), plus a share of transaction fees and gas
  • Genesis blocks initial creation: 100 million
  • Maximum supply: 107.8 million in 30 years, current annual inflation 0.87%

Token Utility & Use Cases

QTUM are paid as fees and consumed as gas for every smart contract transaction, actually every individual smart contract program step. Qtum staking nodes collect these gas fees, and transaction fees, along with the block reward, for publishing the transaction in a block.
