Qchain is a company focusing on building technical blockchain and marketing solutions. We are developing our products on both Ethereum and NEM, as we believe in taking a blockchain-agnostic approach to offer our users the greatest future flexibility, and to also make sure the survival of our product is more independent of the survival of any individual blockchain. Our advertising application will focus on facilitating branded content, sponsorship, and influencer marketing transactions between advertisers and digital publishers or content creators.
Our marketplace product is occasionally misconstrued as competing with Google AdSense. Our marketplace product is not focused on general display advertising, but instead prioritizes native advertising: forms of advertising that actively involve content creators and publishers. Branded content is original content created by content publishers in collaboration with advertisers. The content is sometimes about the advertising company or their product, but other times, can just be an entertaining piece of content that advertisers decided to fund to build up goodwill with an audience or define their branding.

Branded content can range from written posts (e.g. sponsored posts in The New York Times) to podcasts and videos, to parties or stunts executed in collaboration between a digital publisher and an advertiser. Qchain aims to help publishers that are already reliant on native ads — such as Vox, Gizmodo, and The Atlantic — as well as blogs that may wish to host native advertisements but are under-serviced in the current ad environment.

Influencer marketing consists of paying personalities, celebrities, and other prominent individuals for endorsements. We will focus on targeting Youtube, Twitch, and Snapchat influencer marketing on our platform. Advertisers will be able to easily toggle the kind of advertising they are looking to purchase on the marketplace.
We have two tokens, one for each blockchain technology that Qchain interfaces with. The ERC20-compliant Ethereum-based token is Ethereum Qchain (EQC), and our custom mosaic, NEM-based token is XEM Qchain (XQC). As Ethereum and NEM are both respected and rapidly maturing blockchains, we want to give our users the flexibility to choose between two next-generation technologies.
Each blockchain will have its own Qchain utility token: the EQC token for Ethereum, and the XQC token for NEM. The tokens are a critical component of product functionality and are the resources used to participate in Qchain application services. In the marketplace, tokens are transferred from advertiser to publisher, e.g. an advertiser purchases pieces of sponsored content on a publisher's blog.
No. Qchain is specifically for native ads/sponsored content (e.g. an article on a travel blog paid for by American Airlines), sponsorships (e.g. athlete sponsorships, such as a company placement on an MMA fighter’s shorts), and influencer marketing (e.g. an Instagram celebrity posting about a beauty product). We are not focused on traditional display advertising, and will therefore not compete with Facebook or Google.
Initially, we will be looking at tech-savvy companies and tech-savvy websites with loyal followings. People who are aware of blockchain technologies will be the first ones trying this, and these blockchain enthusiasts will be more aware of differences in Ethereum and NEM. They will be more familiar with the general underlying tech and have their preferences.
YES! There is no need to download a separate application, web browser extension, or other resource. All functionality is provided through our web app. Qchain's user-facing components are optimized for efficient day-to-day usage, while all the heavy lifting is executed fairly and transparently across the decentralized back-end.
Qchain’s products will be released in multiple stages, with extensive testing and user feedback at each stage. Our demo is currently available at:
We wanted to go with a name that was simple and descriptive. We initially thought of naming the company Clickchain, but there are too many "Click" names in ad products, so we thought of going with Qlickchain. Then we decided Qlickchain was too long, and truncated it to Qchain.

The nice thing about having a general Q is that one can pretend the Q stands for something else. Some members of the team pretend it actually stands for Quetzalcoatl or Quixotic.
We are building a marketing platform right now, but resulting from our experiences of building this platform, we also have plans to create off-chain solutions to more general blockchain issues, such as transaction disputes and private chain “anchoring” on public blockchains in the future.
For our international communities, we have social channels and discussion groups in Russian, Japanese, Chinese, and Korean. If you'd like to provide community management help or translation services in a particular language, let us know.


Initially, the project will start centralized, as we will have to run the servers and function as the host agent for demonstrations. This will change as the project becomes more mature and we recruit independent host agents during our initial roll out. After the initial phase, we will not be running any central servers. Once enough hosts are recruited, the host network will perform the off-chain computations that verify the contracts between advertisers and publishers. Verification will occur in the host network in pools where multiple hosts check each other, so even the off-chain components will remain decentralized to a large degree.
Ethereum and NEM are the two most promising blockchain technologies right now, and we want to make sure that if a user desires flexibility, we are offering it to them. We are putting consumers first and give them a choice about which one they want to use. After all, when was the last time a user complaining about a product providing them greater freedom and flexibility?

Our goal is to build a great, flexible product with options for our users, and it is for that reason that we are motivated to develop on both blockchains. We see user interest in investing in the project and developing the technology from both Ethereum and NEM, and believe that the positives of giving consumers more choice and flexibility is worth the added development cost.

Both Ethereum and NEM right now are highly promising and thriving technologies. Both blockchains have seen huge growth and interest, and evidence suggests that supporting both will enhance the success of the Qchain ecosystem as a whole. Ultimately, we are interested in building a product that provides the Qchain functionality on a user's preferred blockchain technology. This is the case whether one chooses to use Ethereum, NEM, or both.

We believe strongly in both Ethereum and NEM, and simply picking one over the other not only strips flexibility from users, but also artificially limits the future potential of Qchain. Why only develop on NEM or Ethereum when both are available and exciting technologies?

We are confident in their potential and both are capable of secure and decentralized transactions with future scalability. There certainly is no shortage of momentum or interest in blockchain advertising within both the NEM and Ethereum communities. It is very likely that both Ethereum and NEM will coexist in the future.
We have not seen any indication that supporting both Ethereum and NEM will impede our success. We have dedicated teams working on both backends, so neither technology will impede the development of the other — and we are continuing to bring aboard dedicated developers for both. Since having Ethereum and NEM is something that we have planned from the beginning, our resources have not been strained between the two.
Ethereum and NEM both have unique selling points, and both can be integrated into Qchain to produce something that may not otherwise be possible.

NEM has a security and scalability advantage over Ethereum, and in many ways is better oriented for enterprise from the ground up in its design. On the other hand, Ethereum has more adoption at this point and more public exposure. Coding smart contracts is also more straightforward in Ethereum (which comes at the cost of security). In terms of coding, NEM has the advantage in that no new language learning is required, whereas Ethereum requires using Solidity (which is similar to Javascript).

We see NEM as a fantastic fit for a decentralized advertising platform. Features like the NIS/NCC and PoI architecture of NEM were a huge consideration for us in choosing NEM as one of the two blockchains for Qchain's initial development and launch. We see the advantages of NEM in terms of security and scalability, and are looking forward to broadening NEM exposure.

Speaking more to Ethereum, initial advertisers incorporating Qchain into their marketing strategy won't do so blindly — the ones that do will be ones that are already deeply aware of blockchain technology. Many of these advertisers are invested in the Ethereum ecosystem, are already using other Ethereum dapps, and like the model of smart contracts being stored on all blockchain nodes. In the short term they will most likely prefer to use Qchain with Ethereum. We believe that these blockchain enthusiast advertisers will pave the way for more mainstream advertisers to use our product.

Additionally, mainstream media attention in the U.S. is driving interest in Ethereum, and people in media and advertising are paying attention. The advertising industry is relatively averse to breaking with tradition. We see Ethereum as a starting point for these ad industry stalwarts — a gateway to get them invested in working with blockchain technology, which it is our goal to promote.

An app that supports both blockchains can bring people using Ethereum to NEM. NEM is a great technology, but it currently has a bit less exposure in the US. This is sure to change in the future, and Qchain can be a part of that process.

In the end, we believe that there are technical merits to both technologies. As blockchain enthusiasts, we genuinely wish for mutual success.


In the future, token holders who hold at least 40,000 EQC or XQC minimum will be able to stake their tokens as they function as nodes that host backups for our marketplace application. Stay tuned in the months to come for more information about this.
We recommend MyEtherWallet or Mist for EQC and Nanowallet for XQC.
Total EQC Supply: 54,863,905
Total XQC Supply: 48,813,421
We are a corporation based in the United States, and the state of cryptocurrency trading and definition of a utility token are still in flux in the U.S. As a result, we have to be very careful to make sure we remain in compliance of U.S. securities laws, so we can continue operations. To help us navigate securities laws, we have retained Goodwin Procter LLP.
Team tokens will be locked from usage and circulation until September 2019. Rest assured that Qchain will not dump its tokens on exchanges.
