Qtum Things You Need To Know Before Investing

What Is Qtum?

Qtum (pronounced “quantum”) is a proof-of-stake (PoS) smart contract open-source blockchain platform and value transfer protocol. It aims to bring together the strengths of Bitcoin and Ethereum in one chain. Qtum is built on Bitcoin’s UTXO transaction model, with the added functionality of smart contract execution and DApps. Recently, the platform added support for DeFi applications. As of March 2021, more than 20 tokens have been created on the Qtum blockchain.

To learn more about this project, check out our deep dive into Qtum.

The project was announced in March 2016 and held an ICO a year after, in March 2017, bringing its founders $15 million. The Qtum main chain was released on Sept.13, 2017. Initially, the Qtum coin was issued as an ETH-20 token, but with the launch of the mainnet, it was converted to a native blockchain.

Who Are the Founders of Qtum?

Patrick Dai is the project’s founder and chairman of the Qtum Foundation. He studied computer science at Draper University and then dropped out of PhD from the Chinese Academy of Sciences. He started his career as a product manager at Alibaba and then worked on a series of blockchain projects, including Factom, Vechain, Bitse Group, and Meilink, before starting Qtum in 2016.

The other co-founders are the CTO, blockchain architect Neil Mahi and lead developer Jordan Earls.

Many of the team members listed on the Qtum official website seem not to have an active Linkedin page or a Github profile. It is confirmed, though, that Qtum has several high-profile backers, including the’s Roger Ver and Jeremy Gardner, an early crypto investor turned skincare professional, co-founder of Augur, and EIR in Blockchain Capital.

What Makes Qtum Unique?

Qtum is a general-purpose blockchain that tries to address four issues its founders found most problematic in BTC and ETH blockchain platforms: interoperability, governance, rigidity, the costliness of proof-of-work mechanisms, and difficulty connecting smart contracts with real-life applications. The Qtum blockchain has two unique technologies that aim to solve that: Account Abstraction Layer (AAL) and Decentralized Governance Protocol (DGP).

The Account Abstraction Layer integrates the UTXO (Unspent Transaction Output) account layer inherited from Bitcoin with the smart contract layer inspired by Ethereum. It allows users to build and host applications on virtual machines, including the Ethereum Virtual Machine (EVM) and the x86 virtual machine. It also supports the i686 instruction set and several programming languages like C, C++, Rust, and Python, making it easy to adapt existing apps and compile them for Qtum. Not only does it allow Turing-complete smart contracts, but Qtum also plans to integrate common programming libraries in the form of smart contracts.

The Decentralized Governance Protocol allows smart contracts to change the core parameters of the network, such as block size and gas fees, without ever needing to hard fork the blockchain, which may save a lot of trouble as the network evolves. In addition, miners (stakers), developers, and QTUM holders within the entire ecosystem are involved in blockchain governance through voting, and the blockchain can realize self-management, upgrades, and iteration.

How Many Qtum Coins Are There in Circulation?

According to the Qtum whitepaper, the initial supply of QTUM coins was 100 million, all of which were minted instantly before the project went online. Fifty-one million coins were sold to the public through an ICO process in March 2017. Over that, 8 million coins went to the early private investors, and 12 million were allocated to the project team with a four-year lock-up. The rest is controlled by the Qtum Chain Foundation, a non-profit company registered in Singapore, which will receive it in four parts by March-2021. These are 20 million coins allocated for business development and 9% for academic research and promotion.

The coin supply is not fixed. New tokens can be mined with a block reward halving every four years from the initial block reward subsidy of 4.0 QTUM per block, going through seven halvings to eventually reaching zero by the year 2045, when the maximum supply will reach 107,822,406 QTUM.

How Is the Qtum Network Secured?

The technical approach to Qtum is not the same as Bitcoin and Ethereum currently use. Instead, Qtum chose the MPS (mutualized proof-of-stake) consensus mechanism for network security. It is a modified version of Proof-of-Stake 3.0.

The protocol incentivizes users to keep their coins locked to facilitate and secure block validation. This is called staking. Confirming each block is a competition between coin holders, based on connectivity to the network and a random chance they get to right to validate the block. Unlike the early PoS protocols, here, the block reward is constant and does not depend on coin age to determine the likeliness of getting it. Furthermore, the rewards are spread proportionally to the stake, so the more coins are staked, the more reward the user gets. On top of that, the MPS protocol is protected against “junk contract” attacks by splitting 10% of the block reward between the block-producing miner and nine previous miners and delaying the remaining 90% by 500 blocks.

Unlike the proof-of-work mechanism used in Bitcoin, the proof-of-stake algorithms are significantly less costly to maintain, are more environmentally friendly, and can provide a great deal of decentralization, which is the cornerstone of blockchain security.

Where Can You Buy Qtum?

QTUM is a freely-tradable token available on most exchanges. Pairs for trading include Bitcoin and altcoins, stablecoins, and fiat money.

The top trading exchanges in Qtum are Binance, Huobi Global, OKEx, HBTC, and Hydax Exchange.
