ABOUT

The Qtum Foundation is a Singapore based entity that promotes adoption of the Qtum Blockchain. Project inception began in March 2016, leading up to a successful crowdsale a year later. Over 10,000 BTC and 72,000 ETH were raised in less than 5 days, making Qtum one of the largest crowdfunded projects in history, at $15.6 million dollars.

Qtum is an open source Proof of Stake (PoS) blockchain application platform. Qtum’s core technology combines a fork of Bitcoin Core, an Account Abstraction Layer allowing for multiple Virtual Machines including the Ethereum Virtual Machine (EVM) and Proof-of-Stake consensus aimed at tackling industry use cases.

We believe this will allow Smart Contracts and Decentralized Applications (DApps) to run on a familiar foundation, while offering a robust environment for developers. The underlying technology uses an “Account Abstraction Layer”, which acts as a bridge between the EVM and the Unspent Transaction Output model of Bitcoin Core. Building on Bitcoin’s reliable and proven-to-deliver blockchain, Qtum stacks its Account Abstraction Layer, allowing the Bitcoin Core 0.13 blockchain to seamlessly interact with the Ethereum Virtual Machine (EVM). With this innovation it is now possible to execute smart contracts and run DApps, simply and securely, in environments that were previously out of reach for Ethereum, combining the endless possibilities provided by smart contracts with the stability and maturity of the bitcoin ecosystem. There will also be Oracles and Datafeed functionality, allowing developers to create Smart Contracts built around trusted sources of information.

The Qtum Foundation plans to be the public blockchain for business. Development efforts will allow us to market this platform to various industries, such as: Mobile Telecommunications, Counterfeit Protection, Finance, Industrial Logistics (shipping, warranty, etc), and Manufacturing.

Build decentralized applications you can trust

Combining a modified Bitcoin Core infrastructure with an intercompatible version of the Ethereum Virtual Machine (EVM), Qtum merges the reliability of Bitcoin’s unfailing blockchain with the endless possibilities provided by smart contracts.

Designed with stability, modularity and interoperability in mind, 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, allow Qtum applications to be compatible with major blockchain ecosystems, while providing native support for mobile devices and IoT appliances.

Smart Contracts that Mean Business

Qtum makes it easier than ever for established sectors and legacy institutions to interface with blockchain technology. Create your own tokens, automate supply chain management and engage in self-executing agreements in a standardized environment, verified and tested for stability.

Smart Contract Lifecycle Managment

Qtum, in cooperation with its academic partners, develops tools and methods to standardize the workflow for business smart contract development. This includes the formally verifiable translation of human-readable agreements to machine smart contracts, and the error-resilient specification of their elements, terms and conditions.

Setting Industry Standards

Cooperating with a series of partners and third parties, Qtum aims to establish a smart contract hub, offering secure and thoroughly tested contract templates, tailor fitted for a multitude of industries and use cases, such as supply chain management, telecommunications, IoT, social networking, and many more.

Go Mobile

Building on Bitcoin’s UTXO model, the simple payment verification (SPV) protocol is supported by the Qtum codebase by default. As a result, it is now possible to execute smart contracts from lite wallets, which can be easily installed on any given mobile device, heralding an age of mobile decentralized applications.

With this, the blockchain is finally ready to take up disruption in a world in which half of all internet traffic is being generated by smartphones and tablets.

Account Abstraction Layer

Qtum extends Bitcoins 'Script' language so that it functions as a vehicle to transport code to Qtum’s version of the EVM. With this, it is now possible to execute smart contracts and run decentralized applications, simply and securely, in environments that were previously out of reach for turing-complete blockchains, combining the endless possibilities provided by smart contracts with the stability and maturity of the bitcoin ecosystem.

CROWDSALE

The Token

QTUMs are cryptographic software tokens used to engage with distributed applications (DApps) and smart contracts on the Qtum platform. QTUMs will serve as the staking currency of the Qtum blockchain and fuel computational operations performed by the Qtum network.

QTUM supply and Initial Distribution

With the setting of Qtum’s Genesis Block, one hundred million (100,000,000) QTUMs will be created as Qtum’s total token supply, on top of which ~1% annual Proof of Stake (PoS) inflation will be added.

The QTUM token supply will be allocated as follows:

51% of Qtum tokens (51,000,000) will be distributed through the crowdsale
20% of Qtum tokens (20,000,000 QTUM) will be distributed among founders, early backers and the development team
29% of Qtum tokens (29,000,000 QTUM) will be allocated to community initiatives concerning business development, as well as academic research, education, and market expansion

The Qtum Foundation: Governance Structure

The development and maintenance of the Qtum Blockchain, as well as all services provided by Qtum, are directed and supervised by the Qtum Foundation - a non-profit organization, representing Qtum’s stake and token holders as elaborated below.

In order to avoid the inefficient conduct, open source and blockchain projects often suffer from, and to ensure a coherent and standardized implementation of the Qtum blockchain, the Qtum Foundation was established under the guidance and support of PwC. The Foundation will oversee the development of the Qtum Blockchain, advocate governance transparency, and promote the safety and harmony of the open source ecosystem.

The design of the Foundation’s governance structure mainly considers sustainability, management effectiveness, and fund-raising security in the open source community. The Foundation consists of various committees, such as Executive Judgment, Code Review, Finance & HR, as well as Marketing & PR. The different committees work in cooperation to manage Qtum’s daily operations and special occasions with detailed operational procedures and rules.

Decentralized Governance Protocol

The Decentralized Governance Protocol (DGP) is designed so that individual blockchain parameters can be modified through a specially designed smart contract on the blockchain. Most importantly, this technology allows these blockchain parameters to be changed without any disruption to the ecosystem. After a setting change, no new software must be downloaded by users, and no intervention is needed from stakers and node operators.

The way the DGP works is relatively straightforward. First, a governing party for the DGP makes a proposal to change a parameter. Afterward, all the governing parties for the DGP can vote on the proposal, and if it receives enough approval votes, then the parameter change proposal becomes active. The proposal data is then placed in a standardized format and a particular storage space so that the blockchain software can easily access it without needing to execute the DGP contract directly.
