Brief Overview for Crypto Enthusiasts

Qointum can be simply described by imagining "Ethereum 3.0", it is an improved decentralized shared-state Turing machine with a precise economic model of CPU cycles and storage bytes. The most significant improvements are that Qointum employs post-quantum cryptography that is secure against quantum computers, its smart contracts are scripted in Python which is a far more flexible language used by millions of developers, and it is web-scalable thanks to its torrent-like web protocol QHTTP and light-weight decentralized security Queued Delegated Proof-of-Stake paired with Entangled Chains which enable seamless interaction between contracts across multiple blockchains. The Qointum platform is unrivaled in its ability to host and accelerate the development of new cryptocurrencies, decentralized applications, and decentralized websites.

Overview

Qointum is the Quantum-Secure Trustless Smart Money powering Web 3.0. Secure and trustless digital money like Qointum is known as cryptocurrency.

Qointum is trustless because it is decentralized, anyone with a home computer can join the Qointum network to help verify transactions of digital money, and all computers operate using the same rules written in machine code. Qointum is also transparent, anyone can read the machine code rules that govern it and everyone knows the total amount of money and credit in existence, ensuring that money can not be arbitrarily created at the whim of officials behind closed doors. With a Qointum wallet you are in full control, your account can never be frozen by authorities or become unavailable due to bank insolvency.

Today, research laboratories around the world are racing to build the first practical quantum computer, and experimental 16-qubit processors have already been constructed. With cryptocurrencies that use elliptic curve cryptography (ECC) such as Bitcoin, a transaction from an account will expose that accounts public key in the signature, which can be used in theory by a quantum computer to derive the associated private key, giving an attacker control over the account. A significant percentage of Bitcoins are currently held in accounts with exposed public keys and are thus vulnerable to quantum attack. Qointum employs post-quantum cryptography that is designed to be secure against quantum computers as well as classical computers, thus future-proofing the security of stored value owned by Qointum users from all theorized cryptographic attacks.

Another challenge facing many cryptocurrencies like Bitcoin is the cost of securing their decentralized networks through proof-of-work schemes, which require unbounded amounts of processing and thus consume limitless electricity. The Qointum network provides light-weight decentralized security through Queued Delegated Proof-of-Stake which consumes a limited and negligible amount of electricity, so Qointum users can enjoy a high-frequency value exchange with low transaction fees. Qointum is also ready to handle everyday mobile payments as the network provides instant transaction confirmation by means of a consensus heuristic based on delegate voting.

Qointum is also the first and only cryptocurrency to be scripted in the popular language Python which is used by millions of skilled developers worldwide. It's truly programmable money capable of smart contracts, which are trustless automated rules that govern relationships between parties. Together with full web browser integration and Qointum's new web-scalable Entangled Chains technology which can be described as decentralized databases interconnected through programmable money, Qointum is powering the emerging privacy-centric and cryptocurrency-native Web 3.0.
