Consensus 2018


On Device Key Management Panel



At Consensus, Jordan Earls, Qtum’s co-founder and lead developer, appeared on the “On Device Key Management” panel moderated by Zaki Manian, executive director of the Trusted IoT Alliance. Jordan’s co-panelists, Nicolas Bacca, the CTO of Ledger, and Allison Clift-Jennings, CEO of Filament, discussed the use cases and security aspects of using cryptographic keys for identity, messaging signing, cryptocurrencies, and smart contracts.

Filament, which announced their new USB-compatible Blocklet device at Consensus, has enabled companies to rapidly test and deploy blockchain tools for business use cases.

Ledger, who makes the popular Ledger Nano S device for storing cryptocurrencies, has allowed hundreds of thousands of individuals to safely secure their crypto on a small device.

Jordan spoke about the unique complexities of storing and staking cryptocurrency on the Qtum blockchain since the token has to be in a hot wallet to take part in validating transactions and securing the network.







Meanwhile, at the booth, the Qtum team engaged many of the attendees, businesses, and fans of the project. We had much fun meeting everyone, and it helped us understand our audience better.

We’d also like to thank our dapps that came to Consensus and showed their support, like Bodhi, Vevue, Mossland, Vanywhere, and Qbao.




QTUM Tech Meetup at Columbia



QTUM, together with SpaceChain, Energo, and Bodhi, we hosted another tech meetup at Columbia University on May 12th.

Columbia students and a few faculty member and blockchain enthusiasts in NYC attended the meetup.

QTUM co-founder and lead developer Jordan Earls gave a brief introduction of QTUM’s upcoming X86 virtual machine and the soon to launch global developer tour and online hackathon. QTUM’s X86 virtual machine will enable programmers to write smart contracts with more mainstream programming languages such as Go, Rust, C++, and more. Jordan is leading the team in developing the said VM and currently, it is in the prototyping phase.








Jordan also revealed that QTUM is about to launch its first online hackathon which will last for three months and welcomes anyone who aspires to build on or for QTUM to join. The hackathon will accept online submission and promises handsome financial reward in addition to a spot to QTUM’s global dev con and other community support.

Zz, Founder and CEO of SpaceChain also gave a quick update of the project. SpaceChain OS is a universal space OS that can convert single-operator satellites into multi-tenant ones, thus users can develop different types of space-based applications on a single satellite. SpaceChain OS also enables compatibility between SpaceChain’s hardware and the various applications that the developers are developing/using, acting as a bridge that lets both participants in the space arena and SpaceChain “speak” to each other. Z also announced that their launch plan for its second low-orbit satellite later this year.

KK, co-founder of Energy also gave a great presentation about the recent progress of Energo Las. Energo Labs is committed to creating a dynamic ecosystem that is more resilient, equitable, and responsive to diverse community needs. KK shared her personal story with blockchain and showcased their project with a newly produced video with lego blocks and explained their project nicely and elegantly.

In the end, Sam from Bodhi presented the recent update of Bodhi, a QTUM based prediction market. Bodhi has been launched on QTUM main net and has other exciting news lined up.









Qtum Tech Meetup at Yale



On Wednesday, May 11th, the Qtum team and Bodhi hosted a local meetup at Yale’s campus.

The audience which include professors, students, technologists, and fans of Qtum got to ask David Jaenson, one of Qtum’s core developers, John Scianna, Qtum’s marketing director, and Samuel Suh, from Bodhi, questions about the industry and Qtum.

The meetup took a different approach than the one at Columbia, with a lot of audience engagement. Thanks to the students who came despite finals being over, we hope you are enjoying your summer now.




QTUM Sponsor Crypto Influencer Summit



On May 17th, QTUM sponsored and attended the first crypto influencer summit. Over 50 influencers in blockchain industry showed up, together with entrepreneurs, traders and surprisingly large sum of developers.

During the event, QTUM’s BD Director Natalie Deng moderated the first panel “YouTube in the Blockchain”. Together with four crypto influencers and one blockchain entrepreneur, they discussed the role YouTube played in today’s blockchain industry, the ethics of influencers and how can blockchain projects best utilize the power of social media.

Thanks for the news. I am watching the project and it is of great interest to me. Let's see how it goes.

The Qtum X86 Virtual Machine Launch event will be held on May 23rd in Seoul, Korea. This launching indicates Qtum will enter the next era of Blockchain development, and is a milestone of the Blockchain ecosystem.
More technical details will be released during the event which will be attended by invited guests in the Blockchain area. Free drinks and food will be provided.

Not needed. QTUM its developments are impressive. QTUM doesnt need other projects. I cant wait for its Virtual Machine to go up and running. A sustainable price is a result of tech. improvements. QTUM actually achieves their deadlines, most other projects cant say this. Crypto is nearing the phase where real usecases and real products will make the difference after such a long period of mostly speculation. QTUM with its developments will make the difference compared to other projects imho. Lets see!

What is missing for Qtum to be recognized beyond what it already is? Maybe some attractions can bring new investors or new supporters, i can not find anything negative about this project and it seems a bit transparent in the view of investors. Another factor that developers can think of is a possible partnership with others Blockchains.

Qtum Forges Ahead with Development of Its x86 Virtual Machine and Expanded Network



Qtum is on the move with the announcement of a partnership with Baofeng to begin running 50,000 full Qtum nodes and an upcoming x86 VM to support multiple languages for smart contracts.

Qtum Forges Ahead with Development of Its x86 Virtual Machine and Expanded Network

         Qtum Forges Ahead with Development of Its x86 Virtual Machine and Expanded Network
        
Qtum is on the move with the announcement of a partnership with Baofeng to begin running 50,000 full Qtum nodes and an upcoming x86 VM to support multiple languages for smart contracts.

Qtum is a hybrid of Bitcoin and Ethereum that is based on proof-of-stake consensus instead of proof of work, and is compatible with existing Ethereum contracts as well as Bitcoin gateways. Supporting the Ethereum Virtual Machine (EVM) wasn’t enough for Qtum co-founder Jordan Earls, who has been working on an x86 Virtual Machine for the Qtum system.

Earls comments that a great reason to build a x86 VM is to add more programming language support for smart contracts, his favorite being Rust. The overall list of objectives is much bigger though:

Programming Language Support
Standard Library
Optimized Gas Model
Unlock the full power of the Account Abstraction Layer (AAL)
New possibilities for smart contracts
First-Class Oracles
Blockchain Analysis
Alternative Data Storage
Explicit Dependency Trees
Bitcoin Magazine spoke with Earls with some more in depth questions about some of those items:


Bitcoin Magazine: What proof of concept or scalability testing have you done for the VM?

Jordan Earls: We have a very rough proof of concept we completed a few months ago where we integrated a prototype x86 VM into the Qtum network. This success is what led us to pursue this plan. We are confident that the x86 VM will be more scalable than the EVM, but we are thus far unsure how much. We are designing the VM and all of its APIs and other aspects to be scalable. We are making a big shift in the smart contract world where we actually reward smart-contract developers (in the form of cheaper gas costs) for limiting the features their smart contract has access to, and we are confident it will be faster than current EVM technology.  

Bitcoin Magazine: What are you doing to address the problem with x86 programming in general, where they assume near infinite memory and CPU time being available?

Jordan Earls: We think smart contract development crossed with this x86 paradigm will resemble something similar to real-time or embedded programming, where there are various constraints that developers must always be optimizing for.  

We foresee the same kind of design optimizations happening in the smart contract world as happen in the embedded world, and, for the first time, Qtum's blockchain will allow for these small optimizations to be directly rewarded for all users of the smart contract.

We know these optimizations are not cheap for smart contract developers to spend their time on, so we need to reward developers for taking such steps to keep the Qtum blockchain running smoothly and efficiently.

Bitcoin Magazine: What are some of the advantages with the Standard Library that will help keep smart contract code tight?

Jordan Earls: Currently in Ethereum, if you want to do a simple operation, like testing if two pieces of text are equal, you need to write your own code to do it.

This is a problem for a number of reasons: Developers in a secure context should rely on existing code that's been tested and verified, if possible. A naive implementation of this function will be slow, but a more complex and optimized implementation could have security problems. Deploying this code with your contract means another 100 bytes or so of wasted code that every node in the ecosystem now has to worry about.

Qtum will provide a standard library of functions that contract developers can rely on to have reasonable gas costs, secure and validated implementation and an easy to use interface. This means less bloat on the blockchain, easier to write and understand smart contracts and even a faster blockchain (since these functions can be optimized with native code).

Bitcoin Magazine: What about executable size? These x86 programs tend to be quite large.

Jordan Earls: This is true but also misleading. If I write a C program that just prints "hello world," about 8kB of that is going to just be the number "0." This is because x86 processors (as well as many others including ARM) benefit from a thing called "alignment." The important thing for Qtum is that the wasted bytes doing alignment can be discarded without performance impact. This immediately brings down that C program build to ~1-2kB.

We can reduce even more because we don't need all the baggage required by a standard program for Windows: We have our own "operating system" for smart contracts, so only a dozen or so bytes of actual setup code is wasted.

We have done some actual physical tests with these configurations to compare what an x86 smart contract might look like compared to an EVM smart contract. Our findings indicate that x86 programs are around 10–20 percent smaller than their EVM equivalent and, in many cases, significantly more so. And this was done without the standard library concept that was discussed above. We are not worried about getting usable executable sizes from x86 programs.

Bitcoin Magazine: So the language compiler has to be modified to support the VM? What kinds of modifications?

Jordan Earls: Only minor modifications need to be made. The language compilers do support our x86 VM already, but the Qtum smart contract environment is different from a traditional operating system like Windows or Linux. So, basically, the only big modification we have to make is to tell the language how to communicate with our smart-contract operating system.

Bitcoin Magazine: Is QTUM going to provide language packages or libraries to support the VM so people can just use those?

Jordan Earls: C and C++ will be the first languages we support "out of the box" because they tend to be the easiest due to the way they are designed. We also plan to support Rust. Go should easily be possible. For interpreted languages like Python and Perl, it becomes more complex and we must do research to ensure that they can be supported in an efficient and secure manner.

Bitcoin Magazine: Is this going to impact the development of your eSML smart contract language?

Jordan Earls: We are continuing to research the eSML approach and will decide at a later point if it is still a requirement to achieve our goals. We prefer to not do more work if it won't have a tangible benefit to our ecosystem.


Helping to support all this growth is the partnership announced on January 4, 2018, with Chinese video portal giant, Baofeng. With the help of Baofeng, the Qtum network will be boosted to 50,000 full network nodes, making it the most decentralized blockchain platform with the largest number of nodes with more than Bitcoin and Ethereum combined. The increased size of the Qtum system should provide for improved security, stability and speed, all of which will provide a solid base for the upcoming x86 VM later this year.

Earls projects that the x86 will be integrated into the Qtum main network in Q3 of 2018 but hopes to have a prototype to test with before Q2.

Quantum

What is the origin and meaning of the name "QTUM"? How is it pronounced?

Hi All

I'm staking 1000 coins since December 2017. I've received 6 coins at the end of January then 6 other coins at the end of February.
 
But since the end of February I have no other payment. I have updated my pc wallet as soon as the v0.14.16 has been released...

My wallet is unlocked for staking and the reward period is 26 days.

Any clue or help about the missing rewards since 3 months??

Thank you

A huge deal for both! PundiX nowadays is one of the most promising projects that aim to make mass adoption of crypto payments, providing their POS terminals directly to the merchants. Will look closer to the next development of their cooperation as it could be one of the key factors of mass adoption of crypto in worldwide borders providing of real-life usage of it in the nearest future.

after the appearance of quantum computers all blockchain systems fall under the risk of losing primary keys, that's the main technical complexity of blockchain systems of the future.

Hello Everyone! What is Qtum? what are its features?that can be isolated from the technical features!?
