Qtum has a goal of making it easier for established sectors and major institutions to setup quality interfaces that use the blockchain technology. Users can create their own tokens, participate in agreements that are self-executing as well as automate supply. Not only that, but it will all function in a completely standardized environment that has been verified and tested for ultimate stability... If you’re familiar with Ethereum, looking to get in one something new or use Smart Contracts, then

Pros
  • Qtum has the ambition to become the biggest and most influential cryptocurrency platform in the world. Some would say this is quite a lofty goal, but most would probably agree it is quite unrealistic. The rivalry among the decentralized application platforms is intense and in order for one of them to become mass-adopted, it should offer some disruptive technology solutions that support tens of thousands of transactions per second.
Cons
  • Being a hybrid solution probably increases Qtum’s chances of surviving in the near future, but I don’t think it has too much to offer in the long term. In my opinion, neither the DGP, nor the x86 Virtual Machine are such innovations as to make Ethereum users abandon ship and defect to Qtum.

Working in partnership with a range of partners and third parties, Qtum aims to establish a smart contracting center that provides secure and thorough contract templates that fit many industries and industries. Use cases, such as supply chain management, telecommunications, IoT, social networking, and many others.

Pros
  • As a blockchain system, one basic application is the token. With QtumX, you can easily build a system for the storage and exchange of tokens. Here the term "token" can be: Gold coins in internet games Gift card distributed by supermarkets Air miles got from airlines These usage scenarios demand several features, like high TPS, fast confirmation and thin client. All these features are supported in QtumX.
Cons
  • Infinite Incremental Model, Staking with less loss, Deficiencies with EVM.

Qtum is aimed at the enterprise sectoe, and Qtum had an online post that it had already signed deals with two big companies. The first is Starbucks ,coffee conglomerate, but there is no detail to accompany this partnership. A hybrid Bitcoin blockchain and Ethereum platform takes the best of both worlds and turns it into one glorious sportscar of a blockchain. Smart contracts work on both, this is one business-focused blockchain that is right at the cutting edge of Blockchain as a Service. This

Pros
  • Qtum aims to establish a smart contracting center that provides secure and thorough contract templates that fit many industries and industries, Qtum has a few interesting features such as its proof-of-stake model, and its focus on mobile support. Will this be enough to make it a success? Or even just a viable player a few years down the road? All i can say is, i am excited to see how things unfold, i like it !
Cons
  • Not unused mode to large in this project, i like this project !

The Qtum Foundation is a Singapore based organization advocating the use of Qtum Blockchain. The project started in March 2016, leading to a successful crowdsale a year later. More than 10,000 BTC and 72,000 ETH were mobilized in less than five days, making Qtum one of the largest in history with $ 15.6 million.

Pros
  • DGP (Decentralized Governance Protocol) [2] is a technology used in Qtum, which allows blockchain parameters to be modified through a specially designed smart contract on the blockchain, without any disruption to the ecosystem like soft or hard forks.
Cons
  • My understanding is that plasma consists of a "Supreme Court" smart contract and a side chain implementation that interacts with it... Should the plasma smart contract be compatible with the evm for Qtum? Unless I'm mistaken I would say that it's highly possible

With the setting of the Qtum's Genesis block, 100 million QTUMs will be generated as Qtum's overall token supply, with an additional $ 1% of annual inflation Proof of Stakes (PoS).

Pros
  • Smart contract based applications are also worth expecting. You can transform written contracts or rules into smart contracts of QtumX. By this way, the contract will be transparent, unmodifiable and easy to verify. Using a consortium blockchain to deploy smart contracts has several advantages. The most important one is that the developer only need to run some miner nodes for the blockchain, rather than consume public blockchain tokens which are really expensive.
Cons
  • Every experimental technology exposes some trade offs with its proposed advancements, during my research I found the following disadvantages : Infinite Incremental Model.

QTUM could be explained as a hybrid protocol between Bitcoin blockchain and Ethereum virtual machines. In other words, QTUM is a better bitcoin protocol supporting ETH smart contract. It benefits from upgrades to both Ethereum and Bitcoin in the long run. One of the recent developments in Bitcoin which might really boost QTUM is Lightning Network. Backed by well-known VC and investors, for example, Bo Shen (Fenbushi Capital) and love-him-or-hate-him Roger Ver (Bitcoin investor) and technology…

Pros
  • 1. EVM (Ethereum Virtual machines) makes a coding smart contracts becoming more easily 2. POS 3.0 3. More scalable blockchain comparing to ETH blockchain (UTXO makes quicker verification) 4. Backed by well-known VC funds and investors
Cons
  • 1. Co-founder Patrick Dai is accused of defrauding 200 BTC. 2. The UTXO model is not easy to use with smart contracts and puts limitations which is why Ethereum decided against using it 3. Direct competitors are huge crypto projects, such as NEO or ETH

Qtum is an open source Blockchain application platform Proof of Stake (PoS) algorithm. Qtum's core technology incorporates a branch of the Bitcoin Core, the Account Abstraction Layer class that enables multiple virtual machines including Ethereum Virtual Machine (EVM) and Proof-of-Stake consensus to address industrial use cases. .

Pros
  • For consortium blockchains, the consensus algorithm is usually called PoA (Proof of Authority). Instead of solving a difficult mathematical problem in PoW or holding a large amount of cryptocurrencies in PoS, in PoA, a list of authorized block miners is used to determine which nodes are allowed to create new blocks. The chain has to be signed by the majority of miners, then it becomes a permanent record. It is more efficient and secure since the miners are fewer and more reliable.
Cons
  • Qtum probably has to find the scaling solutions for UTXO model by themselves but i believe in the team.

The QtumX project aims to build a business solution, helping enterprises, organizations and schools to apply the blockchain technology to their areas.

Pros
  • Blockchains like Bitcoin, Ethereum and Qtum are called public blockchains. They have no access restriction. Anyone can send transactions to them as well as participate in the block creation process. In these cases, many consensus algorithms are developed, such as PoW (Proof of Work) and PoS (Proof of Stake), allowing a large number of users to reach a consensus about who can mine new blocks. These blockchains are generally considered to be fully decentralized.
Cons
  • Schnorr has too little effect to be considered as one of the potential solution.

Digital identity means recording some important information in blockchain so that it can be verified and tracked by the public. Using a consortium blockchain to do this can also save money when compared to a public blockchain.

Pros
  • Qtum built on the basis of the Qtum framework, which has proved to be a successful public blockchain. New modules are introduced to meet the following enterprise requirements: High TPS (Transactions Per Second) and short confirmation time. Customizable settings for using in various usage scenarios.
Cons
  • I don't think Qtum is in hands of BTC to fix its scaling issue. i mean it's obvious core team already gave up with scaling while ago. ETH has something like 5-6 scaling solutions waiting in the line while BTC has only one, only one scaling solution which is LN.

Overall, QTUM might be promising to invest. The innovative hybrid combo of Bitcoin’s security and stability and Ethereum’s functionality and efficiency that i guess everyone dream about with smart contracts makes QTUM blockchain promising & great.

Pros
  • QTUM has used an enhanced version of POS and aims to incorporates both good features from Bitcoin and Ethereum. It also utilizes a native multisig wallet which is proven to be secure. It might easy to adopt this technology it uses EVM (Ethereum virtual Machine), any Ethereum smart contract can run on Qtum and vice versa.
Cons
  • Since it uses UTXO model, some says it has some serious limitations thats Ethereum did not uses this model. Rumors said Co-founder Patrick Dai is accused of defrauding 200 BTC.

Qtum has the ambition to become the world's largest and most influential decryption platform. Some people say that this is a very noble goal, but most likely agree that it is very unrealistic. Competition between distributed application platforms is a challenge and must provide a disruptive technology solution that can support tens of thousands of transactions per second for bulk purchases.

Pros
  • The Qtum x86 virtual machine is one of the project's biggest achievements. Qtum supports the new virtual machine, which reduces the barriers for developers to use the platform. The x86 virtual machine supports smart contracts written in common languages such as C, C ++, Python, and Rust.
Cons
  • Qtum has entered the highly competitive field of decentralized blockchain application platforms. It is in competition with EOS and Cardono, all of which aim to become a leading platform for smart contracts. However, EOS and Cardano bring a whole new way of thinking when it comes to distributed computing, and are currently far more disruptive than Qtum's mainstream technology.

Qtum employs a decentralized governance protocol allowing for blockchain parameters like the block size, block time, gas schedules, and the minimum gas price for contracts to be modified without requiring a fork. Additionally, the Qtum team is working diligently on lightning networks & payment channels to allow for 20,000+ tps.

Pros
  • This is a value-adding project to the blockchain community as it enables the flexibility of the blockchain tech to embrace economic-driven services
Cons
  • My problem is in the progress of Qtum App development.

Qtum is a mix of Bitcoin and Ethereum based on proof of stake consensus. The Qtum developer signed the Ethereum Smart Agreement and applied it to Bitcoin's Unspent Transaction Output model (as opposed to the Ethereum Account model). Qtum is very similar to Ethereum: With the Ethereum Virtual Machine, the smart contract is compatible with the Ethereum block chain and is equivalent to gas, but the transaction is written differently than the block chain.

Pros
  • It's Blockchain is based on the unused transaction output model (as in Bitcoin). However, smart contracts are being searched at such addresses as Ethereum. And the gas model is very similar to the ethereum. It looks like you are building an account abstraction layer in Bitcoin Blockchain. Thus, you can handle smart contracts such as Ethereum, and this layer writes transactions to non-Ethereum block chains
Cons
  • Qtum founder Patrick Dai previously participated in the BitBay project(scam project) with another name, Steven Dai. In February 2017, Patrick Dai accepted this fact in the BitcoinTalk forum and later tried to explain the situation. . So this person changed his name so as not to be associated with Bitbay Bitbay founder David has accusined Patrick Dai in stealing 200BTC from BitBay project

overall they have succeeded in developing qtum, the Qtum Project is proud to be supported by some of the most prominent blockchain players, traditional Venture capitalists, and executives from some of the largest technology companies in China. I feel very safe to grow with them.

Pros
  • Qtum is a global project that aims to be a bridge between the Bitcoin and Ethereum communities, the real world and the blockchain world. Therefore their team comes from the Bitcoin and Ethereal communities as well as companies like Baidu, Alibaba, Tencent, and many more. with a solid team will make qtum successful in the future.
Cons
  • they are very special, I don't see suspicion on them.

With the setting of the Qtum's Genesis block, 100 million QTUMs will be generated as Qtum's overall token supply, with an additional $ 1% of annual inflation Proof of Stakes (PoS).

Pros
  • As a blockchain system, one basic application is the token. With QtumX, you can easily build a system for the storage and exchange of tokens. Here the term "token" can be: Gold coins in internet games Gift card distributed by supermarkets Air miles got from airlines These usage scenarios demand several features, like high TPS, fast confirmation and thin client. All these features are supported in QtumX.
Cons
  • Infinite Incremental Model, Staking with less loss, Deficiencies with EVM.

QTUM demonstrates the often-discussed argument that other block chains can work, and Bitcoin can better handle network effects. QTUM does not believe it is a network effect, but it provides all the functions of the Ethereum token and distributed applications to provide additional mining networks and potential nodes. However, transactions are becoming scarcer and more expensive. Developers can create applications for multiple platforms, and QTUM can be used in the future as conditions change…

Pros
  • The project inherits UTXO model from bitcoin for tracking funds and utilizes ethereum’s EVM to allow smart contracts
Cons
  • Qtum is based on proof of the stake model, but 28% of the tokens are held by a single account holder. Currently, 75% of Qtum tokens are in the top 5 accounts. This bad token distribution is something that Qtum should do. Qtum has ported Ethereum gas, but there is no explanation for how Qtum can solve the scalability problem that has plagued the block-chain world for some time.

Qtum is a global project aimed at bridging the Bitcoin and Ethereum communities, the real world and the Blockchain world. It therefore only makes sense that the Qtum group came from both the Bitcoin and Ethereum communities as well as traditional companies such as Baidu, Alibaba, Tencent, NASDAQ and more.

Pros
  • We will try to make most parameters configurable in the Enterprise version. So that the system can be easily applied to various usage scenarios. Some customizable settings are listed as follows: The genesis block: block_time, coinbase. Network parameters: pchMessageStart, seeds. Parameters for the PoA consensus algorithm: interval, timeout. Block reward parameters: initial value, nSubsidyHalvingInterval
Cons
  • Qtum has no bar on minimum number of Qtum for staking, like Ethereum is proposing minimum of 32 ethers to participate in staking process. So people can try to stake a very less amount and in turn try to confirm malicious transactions, which will be more profitable, with a low risk because of lesser stake. Though with less stake such people will have lesser chances to mine the next Qtum block.

The conclusion is that currently Qtum has supported the Simple Payment Verification (SPV) protocol, with the features and convenience that they apply, there may be many users who are comfortable with them

Pros
  • From the Qtum consensus algorithm to support the Simple Payment Verification (SPV) protocol, it is a very good idea, Qtum's goal is to maintain a decentralized network and bring smart contracts to everyone, including light clients in low bandwidth environments.
Cons
  • for me they are perfect because they support all their uses.

Qtum is generated as a hybrid of two main block chains. Nobody knows if it will be a useful combination of technologies or if it sounds just fine. As always, there are big goals and a lot to do in the future. But they have been able to keep promises about their plans so far and followed there roadmap adequately.

Pros
  • proof of stake, so no mining blocks. No masternodes as well. Anyone with any amount of coins will be able to run a node, create a new block in the blockchain and get block reward. Chances will be bigger the more coins you hold. Vitalik butterin has been quoted severally about his love for Proof of stake
Cons
  • There's been a report about problems with the UTXO model in qtum runs on and there's been a warning that smart contracts based on this model have some serious limitations. It's a good point because the Ethereum platform refused to use the UTXO model. And Qtum decided to return there on their platform
