I think maybe this is scam. Same bitbay scammer in this coin also.....

It look like good coin i like my chinese people invest but like bitbay if they do same thing steal from ICO then it is very bad....

Qtum Crowdsale to Raise Over $15m at Six Mostly Chinese Exchanges.
The crowdsale will be at six cryptocurrency exchanges and crowdfunding portals: Bizhongchou, Yunbi, ICOAGE, Allcoin, ICO365, and BTC9.
The Qtum Foundation, developer of the recently revealed Qtum smart contracts blockchain, today announced plans to hold its upcoming QTUM token crowdsale to raise over 13,000 BTC (over $15 million) on six exchanges at once. The 30-day token crowdsale will begin March 16, offering 51 million QTUM for either Bitcoin or Ethereum.
QTUM are the cryptographic software tokens used to engage with distributed applications and smart contracts on the Qtum platform, and will serve as the staking currency of the Qtum blockchain, as well as fuel for computational operations performed by the Qtum network.Read more

Press Update:

Great article from CoinGecko!  

For example:

"For example, if a payment gateway accepts bitcoin today, it already holds the potential to support Qtum transactions without any significant modifications. This would allow Qtum smart contracts to interface with the two largest existing decentralized environments, making the lives of developers and entrepreneurs in this industry much easier."

Excellent research by the author.















"Asia’s Qtum Project Aims to Revamp Smart Contracts

CoinGecko March 07, 2017 - Posted by CoinGecko on Coverage

Last year had its ups and downs for the crypto community. Bitcoin surprised skeptics and alarmists, approaching some all time highs towards Q4. However, many in the smart contracts camp were left heartbroken. It began with a sense of optimism with Ethereum’s long anticipated Homestead release, which was soon depressed by the infamous DAO hack.

The immaturity of blockchain smart contracts seemed to be uncovered by this incident, leaving many investors and developers with the bitter impression that smart contracts are still very far away from causing any significant industry adoption.  

While the gap between promises and reality left the Western market in a state of sensation-fatigue, China seems to be picking up the pace. Backed by heavy government endorsement, the emerging Asian blockchain industry might just turn the tables on the state of decentralized computation in 2017.

One especially interesting initiative is the “Qtum Foundation” - a Singaporean entity overseeing the development of a business oriented blockchain stack to promote the broad adoption of dApp technology. The Qtum blockchain, developed by the Qtum Foundation, is a Turing-complete smart contracting platform, stacked upon a modified version of the Bitcoin blockchain.

Qtum claims that this architecture should solve many instability issues and allow smart contracts to be executed in business-crucial environments that were until now out of reach for Ethereum-powered applications - including mobile devices like smartphones and tablets.

The project is backed by an extensive list of impressive investors and advisors, including Anthony Di Iorio, Ethereum Co-Founder and CEO of JaxxWallet, Chen Weixing, founder of Kuaidi, the Chinese version of Uber, Jeremy Gardner, co-founder of Augur and EIR at Blockchain Capital, David Lee Kuo Chuen, founder of LeftCoast & Advisor at Libra, as well as Bo Shen, Managing Partner at Fenbushi Capital to name a few.

Corresponding with China’s ambition to create a standardized blockchain environment for legacy business use cases, Qtum aims to bridge the existing gap between blockchains and the business world by allowing smart contracts to consistently adhere to changing commercial rules and regulations.

With Qtum, DApps can trigger real-world, off-chain data inputs, auditable by a verified Oracle or trusted mediator - while the contract’s essential elements, such as participants and authorization structures, are secured on the blockchain itself. With this, an authorized party is able to audit certain aspects of a contract, while its elemental properties remain protected by the decentralized environment.

Since Qtum employs Ethereum’s Virtual Machine (EVM) for the execution of smart contracts, the system is compatible with existing Ethereum applications. Qtum’s Bitcoin-based blockchain, nonetheless, also allows the stack to be mostly consistent with the Bitcoin ecosystem, which is especially interesting due to the millions of dollars already invested in this space.

For example, if a payment gateway accepts bitcoin today, it already holds the potential to support Qtum transactions without any significant modifications. This would allow Qtum smart contracts to interface with the two largest existing decentralized environments, making the lives of developers and entrepreneurs in this industry much easier.

The team seems to just use the EVM as a starting ground for more ambitious plans. In Qtum’s recently published technical whitepaper, the team gives details about smart contract lifecycle management which could make smart contract negotiation more akin to traditional contracts. The team also wants to embrace a new smart contracts language that will be more expressive and have “pattern-based design, process awareness, matching of processes.”

The 17th five-year plan, recently published by the Chinese government, lists blockchain technologies among the main development directions in the PRC’s information planning document. China’s Central Bank, the PBOC, has also signaled support for blockchain, with the bank's chief, Xiaochuan, stating to the press that it had spent "significant resources" researching the technology.

With a large part of Qtum’s team based in China, Qtum could capture the demand for local blockchain solutions. Qtum would be the first major blockchain project coming out of Asia. The team is also being supported with its project management by PwC, something no other blockchain project can claim.

With the kind of institutional backing and the investor interest that Qtum has, it seems that 2017 holds loads of potential for blockchain enthusiasts. CoinGecko looks forward to seeing what the Qtum team produces."

move that crypto
Don't fall for the comparisons to Ethereum guys.  That was a legit project that had a 17% premine and a highly respected founder.

This on the other hand....

Escrow information? Without escrow, at least I dare not invest money, since one of your co-founder is dishonest person, AFAIK, Neil is not a professional poker player, more info? Why only invest in exchanges? You can't develop a crowdfunding website by yourself?

Don't forget the 49% premine. Even if I didn't believe some of the dirt on Dai and other team members, the coin distribution and the manner in which this ICO is being held (without escrow, only on Chinese exchanges, no source code provided yet) is worrisome enough for me.

Also, maybe I missed it, but in the updated whitepaper I still don't see where it says what the PoS inflation rate will be which is definitely something that should be disclosed before people invest... 49% premine means they could forge 49% of the coins generated by PoS.

+1, if you think this project is a scam or short term project, do not risk your money, better hold btc and wait for btc price going up to 2000$.

but i invested 20BTC into Eth, and i made about 20 times profit.. and i got 400BTC back.


at highest price, Ethereum investors almost have 80 times profit..  Smiley

Proof? LOL, you are new account, and you claimed to invest in ETH with 20BTC and returned 400 BTC? Who believes you? You are paid shill of Qtum, everyone can see this. I can say I invest in bitcoin in 30 usd. And i have made millions of usd.

some people like this project.. some people dislike the project..

but always invest with you can afford to lose..

i am watching to make the decision..

waiting for the price details....then i will check if it deserve to invest or not.

Patrick will announce the specifications soon.  The Inflation will be low, right now the developers are testing Proof-of-Stake, and we believe it will be 1% (but this could change)

Thank you for the answer.

Do you know if the team plans to stake the premined coins? And if so, how much? Is it different/same for the angel investors' 20% and the 29% dedicated to development etc?

That is a really good question.

We will most likely stake to secure the network. These addresses will be transparent.

Do you have any questions about the Qtum project?  Check out our new FAQ section of the website:  






"What is Qtum?

Qtum is an open source Blockchain project that is developed by the Singapore-based Qtum Foundation. Qtum is a hybrid blockchain application platform. Qtum’s core technology combines a fork of bitcoin core, an Account Abstraction Layer allowing for multiple Virtual Machines including the Ethereum Virtual Machine (EVM) and Proof-of-Stake consensus aimed at tackling industry use cases. We believe this will allow Smart Contracts and Decentralized Applications to run on a familiar foundation, while offering a robust environment for developers. The underlying technology uses an “Account Abstract Layer”, which acts as a bridge between the EVM and the Unspent Transaction Output model of Bitcoin Core.  There will be Oracles and Datafeed functionality, allowing developers to create Smart Contracts built around trusted sources of information.

The Qtum Foundation plans to be the public blockchain for business. Development efforts will allow us to market this platform to various industries, such as: Mobile Telecommunications, Counterfeit Protection, Finance, Industrial Logistics (shipping, warranty, etc), and Manufacturing."








What makes this different than other blockchain projects?

The Qtum project offers many advantages to the Smart Contract development community. This project is designed to implement the best parts of the Bitcoin and Ethereum projects, into a business-friendly blockchain. By implementing the Bitcoin Improvement Protocols, and making use of the Ethereum Virtual Machine, digital currency enthusiasts can finally agree on one platform that will offer stability and direction.







What is the benefit of the UTXO Model over the Account Model?

The account model is similar to a bank account. Each party has a balance and can subtract a portion of their balance to increase the balance of another party in order to send money. This model is conceptually very simple to understand. However, to make this work in a blockchain environment many pieces of logic must be added to avoid “double spending”, spending the same funds twice. This logic makes the account model less simple internally, and adds a number of restrictions.

The UTXO model on the other hand is similar to having an ecosystem built on bank checks (without an actual bank account, the check itself is the money). There is a “pay to” field which in our example provides instructions to how the money must be spent, and each check has an amount. You can not go to cash the check and say “cash half the check and give me half back”. Your “balance” per-se is the sum of the checks which you are capable of spending. This model is more difficult to explain, but because every is either “spent” or “unspent” and there is no in-between, it is much easier to secure in a blockchain environment with less logic required to maintain that security.

Each model has it’s own pros and cons. Accounts are conceptually simpler and thus smart contracts written on an account system tend to be much clearer and easy to understand. With UTXOs however it is simpler to validate a transaction, which can be done simply by verifying that the transaction has been confirmed by the blockchain, in the case of the SPV protocol. The UTXO model also has been tested and proven to be secure by Bitcoin, which has operated for over 7 years with no significant changes to its core model. It has also been proven to be more scalable, and transactions can easily be processed in parallel (which can be more difficult in the account model).

With all of this in mind, we at Qtum felt that building on the UTXO model best aligned with our goals and that adding the Account Abstraction Layer brought us the best of both worlds. Now we gain all of the security and interoperability benefits of the UTXO model, while smart contracts are written as if they were based on the conceptually simpler account model.

yes, 49% premine, no need to invest.
better keep your BTC for some better project.  Smiley

Don't need to tell me that, but ty for reminding everybody that the team doesn't give a shit about concerns a majority of people have expressed here.

Any word on that PoS inflation rate yet? Seriously, I've read the new whitepaper over once and gone back and searched through it with keywords and either I still missed it or they still haven't disclosed it. I honestly just want to know. Are you not interested? Are you just planning to invest without even knowing the rate of inflation? I believe it is of particular importance here since they will initially be in control of 49% of the coin supply, i.e. they will be in control of 49% of potential PoS stake. Which raises another question, are they going to be staking the premine and if so how much of it?

Both the PoS inflation rate and how much of the premine the team will stake seem like things an auditing firm would be required to know, right? So shouldn't they know the answer if PwC is already on board?
