Please PM our campaign manager for escrow services, he is in charge of this project.

702  Economy / Services / Re: QTUM Signature and Avatar Campaign on: January 11, 2017, 02:38:12 PM
The campaign manager is sleeping right now, it's 10:35pm in the Phillipines.  He will add the applicants to the spreadsheet tomorrow.  

Like we said in the OP, if escrow is required we will do it, but we're not sure how an escrow will react to having to send hundreds of transactions a week.  

Please remember this is an avatar and signature campaign, the manager will provide the avatar tomorrow.

If anyone notices any forum rules that we are breaking, please post them immediately so our campaign operates without any problems.

We would also like to point out that we are the first blockchain project with a billionaire investor for our seed round funding.
704  Economy / Services / QTUM Signature and Avatar Campaign [READ THE OP] on: January 11, 2017, 01:00:09 PM
BlackMambaPH just told me that we have received a complaint from the forum's moderators that participants in this campaign have been spamming.  From now on, if we get any more complaints like this, we will remove the participants and report them.  We may suspend or end the campaign if this persists.

Please keep in mind that the campaign manager looks at every post, and counts them as constructive or not.  This doesn't mean the moderators here care, they just see our logo, and if it's attached to spam then we can be held responsible for promoting these kinds of posts.

We can't and don't want to 'control' what people post, we will simply remove you from the campaign if we see spamming.  We have up until now just not counted spam posts as payable, but now if we see a pattern of spammy behavior, you will be removed.

Hello,

Welcome to the Qtum signature and avatar campaign.  First off, we would like to say that we plan on following the rules set out by the forum moderators here:

https://bitcointalk.org/index.php?topic=1684035.0

If you have not read these rules, the TL;DR version is that we will remove you from this campaign if your posts are not constructive.  One thing that we would like to mention is that we do not in any way want to control where and what you post, we only ask that your posts are constructive if you wear our signature and avatar.  If you decide to trash talk our project, that is fine, but obviously we will stop paying you.

We have hired a campaign manager on this forum named BlackMambaPH, he designed our signatures and asked if he could assist in this campaign.  We are paying him to design the campaign and enforce the rules, so please respect him.  He lives in the Phillipines, so please keep this in mind when you communicate with him, your time zone may be different.

This post will be moderated, as there should be no discussion here other than applying to participate.  Scam accusations and trolling are fine, just not in this thread please, we will actually delete posts.  If you want to troll or complain, please make another thread.  We expect there to be a lot of private messages because of this campaign, so please be patient if you send one.

This campaign will pay out in Bitcoin, and if necessary we can use an escrow.  We're not sure how an escrow will enjoy sending BTC to hundreds of addresses, so we will let our campaign manager deal with that problem if it comes up.

All bitcoins paid will originate from a Qtum address:  1qtum1H39JbLjkBZGg4HVsrt9KD6FMS3g

We are still working on the pay scale for the signature campaign.  We will launch it in the Marketplace section of this site.  The site admins may not want signature campaign business being conducted in this thread, so please wait for us to make a new topic for it.

We paid BlackMambaPH for the signature designs, everyone on the Qtum team is pleased with his work.  Right now we are negotiating with him to help execute the campaign.

Give us a day or two to work out the campaign details, and then we can get started!
706  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] [Qtum] UTXO based POS Smart Contract Platform on: January 10, 2017, 01:12:47 PM
A quick documentation update, we are working on the English version of the whitepaper right now and we wanted to give a snapshot of our progress.  

Later this week we will have some press that talks about our goals, and a bit about our investors.

Here is a section 2 snapshot of the whitepaper, it discusses how we integrate the Ethereum Virtual Machine onto Bitcoin Core's UTXO model, while using Proof-of-Stake as the consensus protocol.


Here is a link where you can download the section, please keep in mind it was written by a developer and has not gone through a final edit:


Right now the PR team has been giving interviews to western media outlets, so when they run an article, we will post it here and on our blog.  

The signature campaign will start this week, we are just getting the banners designed and calculating the payment schedule.
707  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] [Qtum] UTXO based POS Smart Contract Platform on: January 08, 2017, 03:13:50 PM
We're just doing a rough draft version of the technical whitepaper, and one of the developers mentioned that we should share some of the diagrams that explain our transaction model.  This image goes into depth as to how we plan on integrating the Ethereum Virtual Machine into Bitcoin Core and Proof-of-Stake 3.0

We'll follow up with a more detailed discussion of what this all means, but this post is just meant to be a snapshot of what we're working on:

We'll get Earlz to make an appearance with a more descriptive post later


708  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] [Qtum] UTXO based POS Smart Contract Platform on: January 08, 2017, 07:54:19 AM
This announcement was released in December 2016 as an abstract way of introducing the project.  Over the next few weeks, there will be updates made to our website and two whitepapers will be released.  We have met with some of the Bitcoin media sites, so there should be some press coming also.

A project of this scope does not move quickly, and I'm sure you will all understand why when we start to release information about our development, partners, and investors.
709  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] [Qtum] UTXO based POS Smart Contract Platform on: January 05, 2017, 07:31:30 AM
Articles must involve original content, they cannot be copy/paste blog posts.  We mentioned earlier that articles need to be approved, so please remember we will not pay for garbage.  Original content, interviews, opinions, and so forth is what we are after.

710  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] [Qtum] UTXO based POS Smart Contract Platform on: January 02, 2017, 12:27:14 PM
Happy New Year!

Many people may be wondering: "What is Qtum?" and we would like to spend some time going over a few things.  We plan to release the Whitepaper in early January.  This announcement thread was launched during the holiday season, and we wanted to just get some translations in place and answer a few questions.  Now that it's 2017, we plan to hit the deck hard and really get things going.

Our lead developer spent a few minutes writing a technical summary of where we stand in the development cycle, so this will be the first update of 2017. 



Quantum Development Status
(by Qtum lead developer Neil)

Major completed milestones:

1- Quantum model:
 
The first challenge for us was to make a model for Quantum that integrates both the EVM and Bitcoin UTXO model. The EVM natively uses a state database, so we had to extend its capabilities to work with a UTXO based accounting model.
 
While we decided to keep a state database for storing smart contracts code and data, our model uses UTXOs for all financial operations of the EVM.
 
After finishing the model, we moved to the implementation.

 
2- Quantum Implementation:

The implementation was based on Bitcoin core 0.13 and cpp-ethereum EVM part. After integrating the EVM code and dependencies with Bitcoin core, we worked on implementing the Quantum model which required adding support for Quantum smart contracts creation, funding and calling through Bitcoin script, and also adding UTXO support to the EVM.
Other implementation details were also finished, including the Quantum gas model, EVM coin picking algorithm and much more.

We now have a fully working implementation of the Quantum model which is being currently tested.


3- Bitcoin core proof of stake:

The proof of stake (PoS 3.0) algorithm was ported from Blackcoin to Bitcoin core 0.13 and is now in final stage testing with dozens of nodes deployed.

What’s next?

1- Quantum wallets:

Work is in progress to make brand new desktop and mobile wallets for Quantum, for the desktop wallet, we are working on a dynamic and user friendly wallet which will include in addition to the classic functionalities, support for smart contract operations and a new innovative design.

Our Mobile wallet is also in the works, with versions for iOS and Android, the initial mobile versions are already in testing
.

2- Merging with proof of stake:

We are currently working on merging EVM and PoS branches of Quantum.

3- Testing Quantum:
 
We are currently testing the Quantum implementation. In addition to Bitcoin and EVM automated tests, we are writing our Quantum specific test suite.
 
Other than automated testing, manual testing is currently taking place as well.
 
After finishing in-house testing, we will require external code reviews and testing from independent and professional renowned software developers and companies.

 
4- Releasing Quantum Sparknet (testnet):
 
Once our initial Quantum prototype has passed internal and external testing procedures, it will be time to launch the Quantum testnet code named "Sparknet". which will be the final real world test before the official release.

Happy new year ! From Qtum Foundation"

718  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN] (QTUM) - A Scalable Smart Contract Platform w/ Proof of Stake on: December 19, 2016, 05:08:51 AM


The Blockchain Made Ready for Business


Build Decentralized Applications that Simply Work
Executable on mobile devices, compatible with major existing blockchain ecosystems



ABOUT

The Qtum Foundation is a Singapore based entity that promotes adoption of the Qtum Blockchain. Project inception began in March 2016, leading up to a successful crowdsale a year later. Over 10,000 BTC and 72,000 ETH were raised in less than 5 days, making Qtum one of the largest crowdfunded projects in history, at $15.6 million dollars.

Qtum is an open source Proof of Stake (PoS) 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 (DApps) to run on a familiar foundation, while offering a robust environment for developers. The underlying technology uses an “Account Abstraction Layer”, which acts as a bridge between the EVM and the Unspent Transaction Output model of Bitcoin Core. Building on Bitcoin’s reliable and proven-to-deliver blockchain, Qtum stacks its Account Abstraction Layer, allowing the Bitcoin Core 0.13 blockchain to seamlessly interact with the Ethereum Virtual Machine (EVM). With this innovation it is now possible to execute smart contracts and run DApps, 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. There will also 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.




Build decentralized applications you can trust

Combining a modified Bitcoin Core infrastructure with an intercompatible version of the Ethereum Virtual Machine (EVM), Qtum merges the reliability of Bitcoin’s unfailing blockchain with the endless possibilities provided by smart contracts.

Designed with stability, modularity and interoperability in mind, Qtum is the foremost toolkit for building trusted decentralized applications, suited for real-world, business oriented use cases. Its hybrid nature, in combination with a first-of-its-kind PoS consensus protocol, allow Qtum applications to be compatible with major blockchain ecosystems, while providing native support for mobile devices and IoT appliances.





Smart Contracts that Mean Business

Qtum makes it easier than ever for established sectors and legacy institutions to interface with blockchain technology. Create your own tokens, automate supply chain management and engage in self-executing agreements in a standardized environment, verified and tested for stability.

Smart Contract Lifecycle Managment

Qtum, in cooperation with its academic partners, develops tools and methods to standardize the workflow for business smart contract development. This includes the formally verifiable translation of human-readable agreements to machine smart contracts, and the error-resilient specification of their elements, terms and conditions.

Setting Industry Standards

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 many more.

Go Mobile

Building on Bitcoin’s UTXO model, the simple payment verification (SPV) protocol is supported by the Qtum codebase by default. As a result, it is now possible to execute smart contracts from lite wallets, which can be easily installed on any given mobile device, heralding an age of mobile decentralized applications.

With this, the blockchain is finally ready to take up disruption in a world in which half of all internet traffic is being generated by smartphones and tablets.


Account Abstraction Layer

Qtum extends Bitcoins 'Script' language so that it functions as a vehicle to transport code to Qtum’s version of the EVM. With this, it is now possible to execute smart contracts and run decentralized applications, simply and securely, in environments that were previously out of reach for turing-complete blockchains, combining the endless possibilities provided by smart contracts with the stability and maturity of the bitcoin ecosystem. Learn more.

Cross Platform and Backward Compatibility

Qtum is compatible with existing Ethereum contracts as well as Bitcoin gateways, and will maintain backward-compatibility even if the system is updated.

Specification

Total QTUM Supply: 100,000,000
Block Target: 128 seconds
Stake Return: ~4 QTUM
Algorithm: SHA256

Whitepaper




The Token

QTUMs are cryptographic software tokens used to engage with distributed applications (DApps) and smart contracts on the Qtum platform. QTUMs will serve as the staking currency of the Qtum blockchain and fuel computational operations performed by the Qtum network.

QTUM supply and Initial Distribution

With the setting of Qtum’s Genesis Block, one hundred million (100,000,000) QTUMs were created as Qtum’s initial token supply, on top of which ~1% annual Proof of Stake (PoS) inflation will be added.

The QTUM token supply were allocated as follows:


  • 51% of Qtum tokens (51,000,000) were distributed through the crowdsale
  • 20% of Qtum tokens (20,000,000 QTUM) were distributed among founders, early backers and the development team
  • 29% of Qtum tokens (29,000,000 QTUM) were allocated to community initiatives concerning business development, as well as academic research, education, and market expansion

QTUM is offered on many exchanges



The Qtum Foundation: Governance Structure

The development and maintenance of the Qtum Blockchain, as well as all services provided by Qtum, are directed and supervised by the Qtum Foundation - a non-profit organization, representing Qtum’s stake and token holders as elaborated below.

In order to avoid the inefficient conduct, open source and blockchain projects often suffer from, and to ensure a coherent and standardized implementation of the Qtum blockchain, the Qtum Foundation was established under the guidance and support of PwC. The Foundation will oversee the development of the Qtum Blockchain, advocate governance transparency, and promote the safety and harmony of the open source ecosystem.    

The design of the Foundation’s governance structure mainly considers sustainability, management effectiveness, and fund-raising security in the open source community. The Foundation consists of various committees, such as Executive Judgment, Code Review, Finance & HR, as well as Marketing & PR. The different committees work in cooperation to manage Qtum’s daily operations and special occasions with detailed operational procedures and rules.

Decentralized Governance Protocol

The Decentralized Governance Protocol (DGP) is designed so that individual blockchain parameters can be modified through a specially designed smart contract on the blockchain. Most importantly, this technology allows these blockchain parameters to be changed without any disruption to the ecosystem. After a setting change, no new software must be downloaded by users, and no intervention is needed from stakers and node operators.

The way the DGP works is relatively straightforward. First, a governing party for the DGP makes a proposal to change a parameter. Afterward, all the governing parties for the DGP can vote on the proposal, and if it receives enough approval votes, then the parameter change proposal becomes active. The proposal data is then placed in a standardized format and a particular storage space so that the blockchain software can easily access it without needing to execute the DGP contract directly.



The Foundation will also seek complementary services to aid our efforts in transparency and professionalism with a professional auditing firm, legal team and a professional digital asset management solution. We hope this will help promote the healthy development of the Qtum Project and serve as a model for other projects.

The content that will be made public to the community on the Qtum website:

  • The Qtum Foundation obtained digital and traditional assets, which include: bitcoin, ether, and other digital assets such as Qtum tokens, as well as, legal tender in the form of USD and RMB
  • Qtum will release monthly spending reports, including employee compensation, operating costs, marketing costs and other expenses



TEAM

Qtum is a global project that aims to be the bridge between the Bitcoin and Ethereum communities, the real world and blockchain world. Therefore it only makes sense that the Qtum team comes from both the Bitcoin and Ethereum communities as well traditional companies like Baidu, Alibaba, Tencent, NASDAQ and more.

The Qtum Project is proud to be backed by some of the most notable blockchain players, traditional Venture Capitalists, and executives from some of China’s largest technology companies.

See the full team at: https://qtum.org/en/team

We are looking for developers to build the next generation DApps on top of Qtum and invite you all to give our testnet a try. We are always on the lookout to enrich our very talented team, the next team member can be you!
