AppCoins is an open distributed protocol of AppStores, using blockchain technology and smart contracts. With over 200 million users, AppCoins (APPC) tokens are the new lingua franca of the app economy, ensuring credibility without middlemen. Aptoide is the largest Android app store with 4 billion downloads, 200 million users and direct participation from over 12,000 developers, including Ubisoft and Zeptolab. Aptoide has more than 70 corporate partners, including OEMs and telecom companies (such as Xiaomi, Oppo, Meizu, and Vivo).

1. Project technology

AppCoins is an open, distributed protocol for app stores based on the Ethereum blockchain and smart contracts. It redesigns app advertising, in-app purchases (IAP), and app approval processes through a circular model. Because more advertising and IAP revenue remains in the app ecosystem, more value will return to the app economy. As an open protocol, it also offers greater transparency and credibility. Multiple app stores can adopt and benefit from this open protocol, and stakeholders will drive its development and adoption. In addition, simple API integration is easily achieved.

With AppCoins, we can integrate app stores, users, developers, advertisers and OEMs. The system is app store agnostic and exists on different mobile platforms (Android and iOS). In AppCoins, the different app stores act as a database of smart contracts, which are associated with each platform core transaction. The system creates a layer of trust for the economy, eliminating many middlemen. AppCoins aims to be the communication bridge of the app economy.

The protocol also includes a system called ProofofAttention. Users, app stores, and OEMs receive tokens as rewards through ProofofAttention. Developers who want to promote their applications can be sure that users have
installed and used it. Users reinvest their tokens through in-app purchases, creating a virtuous cycle that fuels the AppCoins economy.

2. Project Features

1. Transparency and Openness
The mobile attribution model assumes a mistrust between advertisers and publishers. Therefore, it relies on third parties to confirm advertising results. AppCoins eliminates third parties through Proof of Attention, while the underlying blockchain enables inherent transparency at no cost. Costless verification is one of the main advantages of blockchain-based financial systems.

Additionally, AppCoins transactions rely on publicly available smart contracts. This means that all parties are given precise assurances that they can trust each other. Privacy is also preserved: cryptography ensures that we can verify transactions without accessing private data. When we have a system that ensures privacy and is trustworthy, we have a truly open economy that eliminates the risk of transactions that currently exist. It also creates a secure plug-and-play environment for open innovation in the enterprise.

2. The closed loop of the circular economic system
One of the cores of the AppCoins business model is the circular economic system. Value that previously flowed to intermediaries is now retained in the system and used to incentivize users to remain active in the app economy. The concept is in line with the principles of a circular economy and can bring huge financial, social and environmental benefits. The circular economy has already attracted the attention of major global corporations such as Google, Unilever and Renault. The global economy is shifting from a linear model (“take, make, dispose”) to a circular model (“closed loop”). The Ellen MacArthur Foundation estimates the potential impact of annual net savings in the EU at $630 billion[16]. This has led to recent EU funding to support it: €650 million for Horizon 2020 and €5.5 billion for structural funds. Although related to manufacturing, as Google's case study shows, these benefits are transferring to the digital economy.
