AppCoins is an open and distributed protocol for app stores based on the Ethereum blockchain and smart contracts. It redesigns app advertising, in-app purchases (IAP), and app approval flows through a circular model. By keeping a higher share of the advertising and IAP revenue within the app ecosystem, more value is retained in the app economy. This open protocol provides transparency and trust, allowing multiple app stores to implement and benefit from it. Stakeholders are required to contribute to its development and adoption, while API integration streamlines implementation.

AppCoins integrates app stores, users, developers, advertisers, and OEMs across different mobile platforms (Android & iOS). The app stores act as oracles of the smart contracts, associated with each platform's core transactions. This system eliminates the need for intermediaries, creating a trust layer for the economy. AppCoins aims to become the universal language of the app economy.

The protocol also includes a Proof-of-Attention system. Users, app stores, and OEMs receive tokens as a reward through the Proof-of-Attention concept. Developers can ensure that users have installed and used their apps before advertising. Users reinvest their tokens through in-app purchases, creating a virtuous loop that boosts AppCoins' economic growth.
