This round will be the final round for Qtum signature campaign and Social Media campaign, after all, the campaign which is paid with BTC closed, Qtum will open bounty which pay with Qtum token? I like to know this, earn BTC or earn Qtum token will be the same interesting
I would certainly participate when there is another bounty, I like Qtum as I believe it will be a valuable token. I am already expecting that big investment will come and the project will be successful just like the high funded ICO in the past.
Having a Qtum token is a privilege, I will invest and earn it the same time, it's good that way to increase my holdings.
I hope qtum continue campaign
not just the signature and twitter, fb and articles but also
If the fb and put in the article, perhaps not only a particular region but all over the world will be a great discussion.
I hope

Apologize if my sentences are not like as you guys wish
But according to your guys talking about "bounty" many of us really joy in working of it but does we worth of it?
I mean that as the bounty it might be better if what we share were constructive as the purpose to make project will guaranty to the successful
And also I do joy it 😅 but I still need to know am I worth of it Smiley
Thank you and waiting good news as you guys talking About

How can we invest in QTUM? Is there any investments here? We need some instructions here. I want to invest in QTUM. I want to be part of QTUM. More powers and hoping extend your signature campaign

Qtum has been outstanding for the past few weeks with their signature campaigns and its sad to hear that they are ending the campaign but it's been a success and Qtum is undoubtedly the future of Altcoins based on the way they've handled everything and the creativity and diligence of the staff.
We will look at future how to plan of Qtum team, I am sure this Qtum project
will become success  project like Iconomi project.
And Qtum altcoin will be one of the best altcoin in the future

Qtum won't become successful project like Iconomi, it is much better than Iconomi, Qtum will raise at least 10k btc, which is worth 100 million usd. It is 10X of ICN's 10 million usd.

This is maybe the best review I have came across of the Qtum project.

http://news.8btc.com/the-qtum-leap-driving-smart-contracts-to-mainstream-business



Ever since an anonymous group of developers published the groundbreaking White Paper in 2009, titled “A Peer-to-Peer Electronic Cash System” – Bitcoin, the open source system it introduced, kept on delivering its promises uninterrupted.

qtum
The reliability of the network, described by the bitcoin pioneers in a clear and short document of merely nine pages, is truly unprecedented and adequately reflected in the (somewhat unbelievable) 15 billion USD market capitalization of the bitcoin ecosystem it initiated.

 

The blockchain, the technology underlying this achievement, was originally introduced to solve the “double spending problem” in peer-to-peer digital currency systems. However, soon enough it became self-evident that blockchain technology was capable of facilitating much more than allowing individuals to exchange “electronic cash” without having to rely on banks, clearing houses or any other intermediary.

In 2013, a young cryptocurrency researcher named Vitalik Buterin, only 19 at the time, proposed a scheme to generalize bitcoin’s decentralized exchange model, so it could execute far more complicated transactions, which could be tied to binary conditions. For instance: if, and only if, a set of conditions is met (like a product delivered, a service provided, etc.), then a payment should be triggered automatically and irreversibly. This re-introduced the idea of self-executing smart contracts into blockchain discourse – allowing anonymous parties to engage in direct exchange without the backing of lawyers, court orders or the police, taking the idea of intermediary-less p2p commerce to a whole new level.
Buterin and his colleagues proposed to generalize this concept of smart contracts even further, exceeding the purely economic realm of economics, and heralding a new age of decentralized computation. Since smart contracts operate on a binary if-this-then-that basis, Buterin suggested that they could serve as the basis of a decentralized programming language, able to code any application, without it having to be deployed on a centralized server. With this understanding, the Ethereum Project was born.

However, these new exciting abilities came at a price: in order to sustain the complexity of the new smart contracting platform, bitcoin’s elegant and rock solid transaction model had to be modified to the degree that interacting with the ethereum blockchain became a complicated and heavy-duty operation. While bitcoin has been running for almost a decade on, more or less, the same code, and has sparked since then numerous light-weight, mobile applications, and gateways; ethereum – with all its potential – remained a niche work-in-progress, not very well suited for massive mainstream adoption.
Preparing for a Qtum Leap

Understanding both – the enormous potential of ethereum’s decentralized computation platform, as well the importance of bitcoin’s ingenious simplicity – the Qtum team has designed a system which combines the most valuable assets of both projects.
Building on bitcoins reliable and proven-to-deliver blockchain, Qtum stacks a communication layer, allowing it to seamlessly interact with an enhanced version of the Ethereum Virtual Machine (EVM) called the Qtum Virtual Machine (QVM). With this innovation it is now possible to execute smart contracts and run decentralized applications, 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.
Going Mobile

One of the main advantages of bitcoin’s unspent transaction output (UTXO) model is its ability to sustain lite wallets. Lite wallets allow users to interact with the bitcoin network without having to download and sync with the entire blockchain. Instead, lite wallets use the Simplified Payment Verification (SPV) protocol, which only requires wallets to download a small part of the blockchain, while ensuring that they only receive transactions which are necessary and relevant to operate.

On ethereum, however, the entire blockchain needs to be processed to interact with the network. Therefore, if one is interested in using an ethereum-powered application, or communicating with a smart contract, one first has to download and sync the entire ethereumblockchain, which to date weighs up to 50 GB and has a monthly growth rate of 1-5 GB, depending on the ethereum client.
This state of affairs made it impossible to envision a mobile future for fully decentralized applications. Until now, that is. Qtum, based on bitcoin’s UTXO transaction model, allows applications and devices to interact with the Qtumblockchain with a lite wallet, while still being able to process smart contracts on Qtum’s Virtual Machine.

With this, it is finally possible to execute any smart contract on your mobile phone or tablet, as easily, fast and securely as sending a simple transaction from your mobile wallet. With about a half of all internet traffic to major sites being generated by mobile devices, this ability is mandatory if we want to see the massive adoption of decentralized applications (DApps), smart contracts and a p2p economy.
A Blockchain Powered Internet of Things

A smart contract fueled Internet of Things has always been among the primary goals of the decentralization movement, and rightly so. Imagine an apartment door that unlocks automatically if and when the owner receives the due payment or a rental car that can be picked up by whoever paid the fee, without having to sign forms or leave a security in escrow. Any given device could be locked or unlocked for predetermined periods, according to a smart contract where all parties agree upon in advance.

Envisioning such a decentralized sharing economy becomes much easier with Qtum’s lite wallet functionality. Instead of forcing each and every device, connected to the IoT, to act as a full node, smart devices could easily sync with the blockchain using a small amount bandwidth and storage, allowing for a much more agile and efficient network.
Scalability, Speed, and Efficiency

Both, ethereum and bitcoin, are based on a similar consensus scheme to ensure the coherence and security of their blockchain. Consensus in this respect means that all nodes in the network compare their results, so to speak, to make sure that only entries everybody agrees upon are recorded on the blockchain. There are several ways to reach consensus; the classic bitcoin/ethereum method is called Proof-of-Work (PoW) mining, which functions by agreeing that the most accurate chain of blocks is the one associated with the most work, or computational tasks, behind it. Mining makes attacks very costly due to arduous, and otherwise useless, computations demanded from miners participating in the block-verification game.
Mining is very wasteful, in both terms of energy consumption and time. Essentially, millions of devices are performing non-functional operations for the sole purpose of rendering attacks on the network expensive.

Qtum is among the first fully decentralized and Turing-complete blockchains to utilize an attractive and much more energy-efficient method to maintain coherence with a Proof-of-Stake (PoS) consensus algorithm. In a PoS environment, nodes have to pose a staking fee to participate in the validation game, which is automatically foreclosed upon if the node is shown to operate with malicious intents, hence rendering attacks costly and inefficient, without having to waste precious computational resources.

Further increasing speed and efficiency, bitcoin’s UTXO transaction model, implemented on Qtum, allows the network to process several transactions in parallel and in any given order. This is in stark contrast to ethereum’s architecture, which demands all transactions to be processed one at a time, in chronological order – making it so that at any given moment all nodes connected to the ethereum network process only one single transaction, while all other transactions have to wait in line.

Compatibility across the board
Utilizing an enhanced EVM analog, the Qtumblockchain is compatible with existing ethereum-based smart contracts. Ethereum contracts can be ported to Qtum with little to no change to their code and execute as expected. Furthermore, Qtum implements complete backwards compatibility, meaning that once a decentralized application or contract is deployed on the Qtum network, they will stay operational, even if the system is updated. With this, Qtum solves a huge problem, very well known to ethereum developers, who very often find their applications rendered useless by recurring changes to the ethereum network.

The bitcoin-based UTXO transaction model also ensures that Qtum will be mostly compatible with the existing bitcoin ecosystem, allowing Qtum users to benefit from the industry’s top-notch innovations, fueled by hundreds of millions of dollars already invested in the space. For example, if a payment gateway accepts bitcoin today, it already holds the potential to support Qtum transactions easily and link to Qtum’s API, without any significant modifications to their operation.

Bridging the Gap between Blockchains and the Business World
Despite their great potential, businesses, governments, and other legacy organizations still struggle with implementing blockchain-based solutions. These groups, in large part, aren’t using blockchain smart contracts because they operate in an isolated blockchain environment. In this respect, the greatest advantage of smart contract based commerce is also its biggest impairment.

To circumvent these technical and legal hurdles, and to unleash the full potential of the blockchain, Qtum introduces the Master Contract concept. Master Contracts allow DApps and smart contracts to trigger real-world, off-chain data inputs, auditable by a verified Oracle or the contracts mediator – while the contracts essential elements, such as participants and authorization structures, are secured on the blockchain itself.

This allows blockchain-based commerce to adhere to changing commercial rules and regulations, while interfacing with real-time data inputs from stock markets, weather forecasts, news agencies, etc..
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 more. With this, it will be easier than ever for established sectors and legacy institutions to interface with blockchain technology and enjoy their benefits
Conclusion
Smart contracts and DApps hold great potential for the future of both – the emerging p2p economy and the Internet sustaining it; but for them to reach mainstream adoption, decentralized applications have to be accessible, easy to use and operational on all major platforms used by the end consumer.

With this in mind, the Qtum team is building on well-established technologies like the bitcoin network, as well as on state of the art innovations, to produce a blockchain compatible with the major existing ecosystems, as well as cutting-edge capabilities these are lacking. Join us for a Qtum leap towards the future of mobile smart contracts and the mainstream adoption of decentralized applications.

How can we invest in QTUM? Is there any investments here? We need some instructions here. I want to invest in QTUM. I want to be part of QTUM. More powers and hoping extend your signature campaign

Qtum has been outstanding for the past few weeks with their signature campaigns and its sad to hear that they are ending the campaign but it's been a success and Qtum is undoubtedly the future of Altcoins based on the way they've handled everything and the creativity and diligence of the staff.
Qtum is the highest rate signature campaign I've to join ever, I'm glad to be part of this project and will invest some of my money that I earn in signature campaign, I hope that they have bonuses in ICO phases.

Yes, the signature campaign is the highest paying one.  It will be hard to find one that tops it.  When you say bonuses in ICO phases, do you mean early bird bonuses?  Like 20% bonus for day one and stuff?  I hope they offer that too and only offer a reasonable bonus.  I hate ICO's that offer 50% bonuses, those usually gets dumped on day one when it gets listed on an exchange.
That is only the most important, a reasonable bonus because this project is a legitimate one. It is very popular in the community as they spend a decent amount for advertising only, and with that kind of actions, you can tell they will make a good development which is worth of our investment then.

It was said that a crowdsale will happen in 3 major Chinese exchanges but the names of the exchanges was not mentioned. I want to ask if it is possible for the people outside of China to register and make accounts in these major Chinese exchanges to participate in the crowdsale. If it is possible what are the 3 major exchanges the QTUM development team is referring to?

I guess the 3 major chinese exchange websites are BTCC, Huobi and OKCoin. I have heard a lot about OKCoin but do these exchange website allow international users to trade or only Chinese users are allowed to trade here?

Not only allowed to trade but also allowed to register to make an account to participate in the ICO. Maybe this ICO is more catered for the Chinese investors and that they do not really care about the foreigners and QTUM is based in Singapore.

I hope the QTUM representative can give us answers.

are you guys removing posts that bring up how other crypto currencies can do what qtum does? I don't see my old message I was trying to see the point of qtum and why to invest in it. I might of lost my message i see a lot of interest. I am not trying to knock your product before I invest I llike to look at the pros and cons. I just don't see how it stands out over other eco systems that already make smart contracts on bitcoins block chain like rootstalk. UTXOs are being added in Metropolis. This was announced in a recent blog post by VB. Ethereum is going to have pos. I just don't get it.  I am interested in projects that do combine bitcoin and ethereum together thats why i am posting not to knock down QTUM. From all the interest I see in messages I am trying to find out what is making everyones so excited about this project or they key difference that makes this stand out.

Qtum has a lot of support in the business media, many articles in renowned publications such as Forbes, successful signature campaign on bittalk and as a result of the development team has managed to attract a lot of attention of potential investors to its ICO. Qtum project will develop successfully and achieve its objectives in the near future.
Qtum is an outstanding project and it will create its name. There is a lots of material available , articles etc and this chat, which gives information about each and every aspect of Qtum project.  All their projects are highly attractive and give high incentive to the ones who joins them.

I'd like to know, since this is mainly a Chinese run effort, what % of time/capital is spent on "marketing" in China vs rest of the world ?  Are you guys going to actively translate everything in english, french, etc - I guess what i'm asking is, is there effort to make this truly an international project ?  I view the future a bit like in the show firefly, english and chinese mixed together everywhere Smiley

I think Firefly was English and Japanese, but I might be wrong.

We don't have to market this in China as much as we do in the West, our staff did a great job building a community.  Right now our Chinese community manager is working hard to do some meetups in Beijing, Shanghai, and Shenzen and we will be at each event.  It's happening this weekend so we'll provide some pictures.  In the West we're focused on delivering content so people have more information about the project.  Right now we currently have a room in the Shanghai office where guys from USA, Canada, and Europe just focus on documentation.  If it's good, we publish it, and ask the Chinese translator to make a clone document.

Qtum will have a very unique community moving forward, it gives people with common interests on other sides of the planet the opportunity to meet and discuss something they're both involved in.
