Solutions.

To prevent fraud by (fake) users several mechanisms will be used such as setting a lower limit, e.g. one install a day and three per week for unknown users, preventing cashing out of tokens. I.e. the user has to use the AppCoin tokens for in-app purchases.
To deal with the risk of attention, a client-side method, running in the smartphone’s untrusted environment, will be used to register that a user is paying attention to an app (installed from an app store) for a certain amount of time. Once the necessary requirements (such as the app being in foreground, or the device screen being on) are met, a proof-of-attention (PoA) is issued using through a server-side platform and stored in the blockchain.

If I got it right thanks to Blockchain technology there is no middleman in AppCoins. What advantages does it give to advertisers and users?

That is a very interesting scheme. Especially because it is based on advertisement, developers reputation and IAB. But can anyone explain to me what IBA means? I would really appreciate it.

Good day. I've found out that audience targeting will offer certain apps to users depending on Smart comparison. Does anyone know how that works?

That's a very valid concern. Our whitepaper (https://appcoins.io/pdf/appcoins_whitepaper.pdf) on page 13 suggests a number of possible solutions:

• Thresholds: The app store sets a lower limit, e.g. one install a day and three per week
for unknown users. As the user has more transactions in the blockchain, the level of trust
increases and the threshold is slightly raised. The user would never be able to do more
than two installations per day in any case.
• Cash out: As mentioned before, the user is not able to cash out tokens. He has to use
the AppCoin tokens for in-app purchases. A fraudulent user could try to register as a
developer and buy items inside his own app, but 15% of the transaction volume would be
lost (app store and OEM margin) and it would be easier to detect a fraudulent pattern
for that user.
• User Fingerprint: The fingerprint of the user (a unique identification to detect double
attribution) is not done only at the smartphone level but, more importantly, at networking
level. The IP of the user smartphone, as well as routing information, is used in the
fingerprint.
• Shared information: The existent transactions with the fingerprint information will
persist in the blockchain, allowing the different app stores to access and avoid cross-store
fraud. The partial anonymity of the user is accomplished by using hash functions (like
SHA256) in the fingerprint.
• Targeting: It is the store that sends the Ads for the user, trying to do an intelligent
matching between the user and the running campaigns. The client cannot try to install
an advertised app that was not targeted to him.
As mentioned before, it is impossible to totally eradicate fraud since the smartphone is an
untrusted environment. The goal is to create enough difficulties for the attacker beyond the
point that the effort and resources needed to explore the attack vector do not compensate the
benefits extracted from that attack.

Problems being solved:

The central authorities behind the app stores reap a disproportional high share of the created revenue in the smartphone value chain.
Centralization also stifles competition and innovation. Apps are commonly censored if they compete with the app store owner’s economic interests.[1]
Risk of fake person which consists of the impression of the ad and later installation being presented to a non-real person (bot…) with the purpose of deluding the advertiser.
Risk of double attribution whereby there is a possibility of the same user to count twice as a conversion, leading the developer to pay two times what was due.
Risk of no attention which consists in the user installing the app that is being advertised but paying no attention to it.
Risk of data leak which consists in the information regarding the user being leaked to third-parties for advertising purposes.
Risk of default which consists in the developer creating a campaign but not having enough funds to pay the conversions that are generated in that campaign, leading to him not paying the due amount.
Risk of repudiation which happens when the developer does not recognize the installation, failing to attribute the conversion to the publisher. The attribution is generally monitored by tracking platforms like AppsFlyer, Adjust or Rodin that have multiple variables that can be changed by the developer to define what it considers a real attribution.
The number of users with a credit card loaded in the store is still a minority.
Risk of digital goods lost may happen when a user buys a digital good inside the game or app but it is not delivered. Often, the user does not have a way to recover the payment or claim the digital good.
Risk of double payment occurs when the user pays twice for the same in-app item purchase. Also in this case, the user may not have a proof that they paid twice.
Risk of digital items cloning when the user is able to duplicate and transfer the digital good to another user, leading to losses for the developer that charge once for a digital good that is used twice.
Risk of malware is the possibility of an app or game submitted to the app store being infected with a virus or malware that steals data or damages the user’s device. [2]
Risk of censorship when an app store blocks the publishing of an app or game based on political, religious or social factors that are subjective and totally unrelated with technical aspects.

Hey everyone. I've read that the app is going to use Binder infrastructure. But I can't really get what exactly. Can anyone explain this to me please?

Good day! Yes, there is. Hard cup is 60-120 ETH.

I wonder if there is hard cup during ICO?

Hello. The sale is going to be on a little bit more than a month, it starts on December 13 and will be over on January 15!

Hey everyone! Can anyone tell me how long sale is going to be on?

AppCoins ICO is a project that seeks to build an open and distributed protocol for App Stores. The protocol will drastically improve and speed up advertising, in-app billing and app approvals, using blockchain and smart contracts technology.

In advertising, the protocol guarantees not only that the users install apps but that they pay attention to it during at least 2 minutes (Cost Per Attention – CPAt). The value invested by the developer in CPAt is then used to award the user with AppCoin tokens for their attention. These AppCoin tokens are stored in user’s wallets.
In App Purchase transactions will grow because users can make purchases directly, using their earned AppCoins or by purchasing them through various payment methods. Financial transactions are registered in the blockchain and later used to detect double spending and to guarantee user authenticity.
App approvals are made universal and more transparent through a developer reputation system. The reputation is tied to the financial transactions on the public ledger and is auditable. A dispute system will be created so that AppCoin owners can open a ranking for developers.

Hello. I'd rent that users can spend their tokens for purchases within the apps. What about the owners? Can they exchange tokens to fiat money?

Oh yeah, that might happen. But this person will lose 15% on commissions as well as AppCoins will have certain algorithms that after sometime will be able to spot a fraudster.

But fraudster can register as a developer and add his own app to the system so he can make purchases.

You can't withdraw money. You can also make purchases in different apps.

that sounds interesting. How can I withdraw tokens to my Account?

hello. Of course it's hard to deal with the fraud but we are trying to do that! In AppCoins Store app we are planning to limit the number of installations for new users. You can download only one app a day but not more than three a week. After sometime we will increase number of installations but the maximum is going to be two a day per user.

it's just bad that you still didn't fix the problem with fake users. I'm pretty sure Best people are going to earn a lot of tokens and the advertisers will lose their money.

Should you get you some APPC?
The ICO just got reviewed on cryptocoinsmarket . Here is the review guys. Kindly let me what you think. Thanks
