I want to know the ICO tonight, will those investors panic buy this scam? Or they will forsake the abandoned ship? Who can guess the prediction? IMO sheep will buy it hard.

Qtum itself is a good project, but because of a person's evil line led to the whole project into a panic, I feel sorry for this, I hope good, I will continue to focus on the progress of the project.

Press Update:




John Riggins from BitcoinMagazine.com discusses the Qtum GoMobile strategy for Smart Contracts:




https://bitcoinmagazine.com/articles/qtum-reveals-go-mobile-strategy-smart-contracts-and-iot/






by John Riggins

John is based in Shanghai, China and is the Head of Operations, Asia Pacific for BTC Media.


Smart contracts and decentralized applications (DAPPs) are coming to mobile phones, tablets and IoT appliances according to the Qtum Foundation, the Singapore-based foundation driving the development of Qtum, the open-source value transfer protocol and decentralized-application platform for businesses.

The first blockchain protocol that can execute smart contracts with a proof-of-stake consensus mechanism based on an Unspent Transaction Output (UTXO) model, Qtum believes mobile stakeholders will be an important part of its network and will include businesses as well as individuals.

Speaking to Bitcoin Magazine, Qtum Co-Founder and CEO Patrick Dai stated, “We want Qtum to be the easiest blockchain network to use. That’s why we are pushing our Go-Mobile strategy. Today, everyone and everything is moving, that’s why we can’t have a network that is run by stationary objects.”

Qtum makes this possible through a combination of features of the Ethereum and Bitcoin protocols. Existing smart contract platforms require clients to run a full node and hold a full blockchain copy to run DAPPs, an untenable prospect for smaller devices in a low bandwidth environment. Qtum gets around this requirement by stacking the Ethereum Virtual Machine (EVM) on top of Bitcoin’s UTXO architecture, making EVM accessible with lite wallets and the SVP protocol.

This innovation allows users to interact with the Bitcoin network and validate their own transactions without having to download and sync with the entire blockchain.

“Making smart contracts work on smartphones and tablets heralds a new age in the field of decentralized computation,” said Dai. “With about half of all internet traffic being generated by mobile devices, every real-world use case for decentralized applications would massively benefit from mobile support — especially if we’re taking the tendencies of developing markets into account.”

Highlighting Qtum’s goal of being a protocol for commercial applications, Dai also noted that “bringing the blockchain to mobile devices isn’t just about consumers, it’s one of the primary platforms for businesses.”

Following heavy community interest, Qtum decided to bring forward the release of a source code snapshot for public review, illustrating how the platform will work.

In addition to bringing smart contract and DAPP functionality to mobile and connected devices, Qtum sees its platform as a way for smart contract technology to be utilized to control “non-smart” hardware, bringing even legacy hardware and devices into a blockchain-secured IoT.

“Relying on existing Raspberry Pi–like devices already present in most standard appliances, Qtum smart contracts can potentially control any device with an accessible API,” said Jordan Earls, co-founder of the Qtum Project. “This way the interaction of ‘things’ in a given business could be programmed and orchestrated with very little investment in specialized hardware.”

With smart city initiatives aiming to utilize blockchain technology to support connected infrastructure and automated services being announced in the last year for China by the Wanxiang Group and for Singapore by the Singaporean government, the environment may be right for Qtum to roll out the feature-rich protocol they have been building.

The Qtum Foundation, having engaged PwC for project management support, will conduct a crowdsale of its Qtum blockchain token starting on March 16. After the crowdsale, further testing of the Qtum blockchain will be conducted before the platform goes live.

People be not be fooled by all these paid for press articles, remember Decloud and recently Ascendancy. You have more to lose here than to gain. The recent Altcoins rally has proven that you can get good value buying after ICOs

Don't forget QTUM has no escrow, they can run away with fund easily, declouds had fake escrows, Ascendancy scammed escrows, what the tragedies.

Also, the price for Ethereum has been changed:




I guess it's not in Qtum's playbook to be forthright and declare that the old and new Allcoin has always been owned and operated by Chinese, with Mark Gates (or Gate, depending on what day it is) still on staff, first as a UK-based entity registered nowhere, and now a Canadian-based registered entity that exercises the fine art of copy & paste.

Further, the Qtum user account has NEVER penned the name of the author of any of its posts on this forum, thus we have no idea who from Team Qtum is doing the talking. It could be Patrick, Jordan, Brett or some other high-up staff member, or it could be Lucy Long from Allcoin for all we know. Hell, it might even be Paul Vernon or Marshall Long, the latter given that Lucy Long is on staff at Allcoin.

One more thing. Let me guess. Team Qtum is waiting on Leroy Fodor to complete the math computations so to fill in the last three missing figures, the placeholder currently reading TBD. Let's see if Leroy's numbers match mine for all five: 110; 105; 100; 95; 90. Looks like it needs to be changed again: 130; 125; 120; 115; 110.

Press Update:


JP Buntinx discusses our Source Code Snapshot and our mobile Smart Contract platform on NewsBTC.com




http://www.newsbtc.com/2017/03/14/qtum-announces-blockchain-platform-mobile-smart-contracts-iot-releases-first-source-code-snapshot/








By JP Buntinx
6:25 pm March 14, 2017


The Qtum team unveiled the first source code snapshot on GitHub earlier today. This marks quite a significant milestone for this smart contract-oriented project, as it gives the whole world a peek at what the future will hold. Developing an open-source blockchains tack for legacy business use cases is a massive undertaking, and the Qtum Foundation wants to be as transparent about this project as possible.

Ever since Qtum announced their plans, the cryptocurrency community has been buzzing with excitement. A lot of developers and coding enthusiasts requested to see the source code. The Qtum Foundation takes these requests very seriously and decided to unveil a source code snapshot for public review. Unlike other projects, which tend to keep their source code under wraps, the Qtum Foundation welcomes public review and any feedback community members are willing to provide.

The full source code for the Qtum project will be disclosed on GitHub in Q2 2017. This date also marks the launch of the Qtum testnet. Once this source code is revealed, the whole world will gain valuable insights into the code history and all git commits by the developers. It is good to see this team embrace transparency and public review, as that will help legitimize this project as a whole.

Blockchain Platform for Mobile Smart Contracts

In other Qtum news, the team also announced smart contracts and Dapps on the platform will function on mobile and IoT devices. Go Mobile, as the strategy is called, is designed to prepare blockchain technology for the mobile space. Considering how Qtum allows smart contracts use without requiring specialized software, it makes a lot of sense to extend this functionality to mobile and IoT devices moving forward.  More details can be found in the organization’s whitepaper. In the video below this article, interested parties can see a smart contract operating on an Android phone.

Qtum co-founder Patrick Dai stated:

    “Making smart contracts work on smartphones and tablets heralds a new age in the field of decentralized computation. With about half of all internet traffic being generated by mobile devices, every real-world use case for decentralized applications would massively benefit from mobile support – especially if we’re taking the tendencies of developing markets into account.”

Additionally, the Qtum blockchain token crowdsale will commence on March 16. Six cryptocurrency exchanges will facilitate the crowdsale, which is an industry first. It is evident there is a lot of anticipation associated with Qtum. Moreover, some of the industry’s most prominent figures are backing Qtum at an early stage, indicating there is plenty of reason for optimism.

I see on yunbi

eth raised 2400
btc  raised 2300

Not bad start on a first day !!!

Most are bought by Chinese, yunbi is full of Chinese rich but bad brain investors, they will cry like ANS investors, the price will be dumped under ICO.

By the way what was ICO price for antshares and current price now?

If I remember correctly, the ANS second ICO price was 20000 sat, now is 11k sat. Qtum ICO price is 0.0002X btc, I will buy some if the price is 10k sat after ICO.

About 50% of 13,400BTC sold in 50 minutes.

EDIT: it's at about 6750 right now, just shy of an hour in, when you calculate the Ethereum.
