QTUM Review

6 min readApr 23, 2020

QTUM, pronounced Quantum, is not new to the cryptocurrency scene. Its entry into the market came in 2016 as a superior solution to problems that plague both the Ethereum and Bitcoin blockchains. Its vision was to bring the best of both worlds into one network that would be far more superior to the Ethereum and Bitcoin networks individually. Many referred to it as the “Ethereum killer.” This idea saw it gather around $15.6 million in 2 rounds of ICO crowdfunding in early 2017. In this review, we take a deep-dive into QTUM and uncover whether or not QTUM has lived up to its name.

What is QTUM?

QTUM is an advanced blockchain technology whose foundation lies on Bitcoin’s blockchain combined with Ethereum’s EVM (Ethereum’s Virtual Machine). In other words, QTUM has bridged the gap between the two technologies to produce a network that has the best of both worlds. For instance, Ethereum’s EMV gives QTUM a stable dApp environment while Bitcoin provides extensive security. The integration of the two technologies happens via the introduction of a third layer known as “Account Abstract Layer.” It then wraps them up in a POS (Proof-of-Stake) consensus to beat the huge energy requirements of POW (Proof-of-Work).

Therefore, QTUM has made smart contracts more secure while allowing for interoperability between Bitcoin and Ethereum. As such, QTUM is poised to benefit from advances in both technologies. Furthermore, any smart contracts built on Ethereum can be easily ported over to QTUM with great ease. By doing so, it hopes to increase the range of smart contracts applications, especially for institutional and business purposes. It makes it easier for businesses to build and execute smart contracts by offering a diverse range of tools, templates, and plug-and-play options. It also offers a native wallet, oracles that allow off-chain data to be used, and a smart contract management application.

How to Mine QTUM

One of the ways that you can get your hands on a QTUM coin is through mining. Mining, in this case, is the act of securing the QTUM network while at the same time, increasing the overall supply of QTUM in the network. As suggested earlier, QTUM uses the POS consensus mechanism. It means that you can only mine QTUM through staking. You don’t require very expensive mining software such as ASICs. Neither do you need large quantities of energy. QTUM POS mining is environmentally friendly and works on the principle of random selection which promotes more individuals to stake.

To stake, you need to have stored QTUM crypto in an address for 500 blocks, that’s about 17 hours, and then run their full node software on a computer that remains connected to the QTUM network 24/7. Since the system operates on the principle of random selection, POS is like winning a lottery. However, you can improve your chances of being chosen by having a large stake in each validation. The higher the stake, the greater the probability of block validation, and then the collection of the QTUM POS reward. Currently, yearly ROI stands at 4.43%.

Has QTUM lived up to its name of being an ‘Ethereum killer?’ No, not yet at least. However, one thing that QTUM has lived up-to is combining the value transfer capabilities of bitcoin with Ethereum’s smart contracts applications. It has delivered the best of both worlds, providing an environment attractive to developers who are looking to move away from popular platforms. Additionally, it has directed its focus towards the business world shaping itself up as a serious player in the 2020 blockchain sphere. While it has a lot of competition, if it focusses on making good on its promises, it might just live up to its name.
