AGChain: A Blockchain-based Gateway for Trustworthy App Delegation from Mobile App Markets
This addresses the need for enhanced transparency and secure downloading in mobile app markets, though it appears incremental as it builds on existing blockchain and IPFS technologies.
The paper tackles the problem of ensuring trustworthy app delegation in mobile app markets by introducing AGChain, a blockchain-based gateway that achieves effective security and decentralization with minimal gas costs of around 0.002 USD per app upload and an average overhead of 12%.
The popularity of smartphones has led to the growth of mobile app markets, creating a need for enhanced transparency, global access, and secure downloading. This paper introduces AGChain, a blockchain-based gateway that enables trustworthy app delegation within existing markets. AGChain ensures that markets can continue providing services while users benefit from permanent, distributed, and secure app delegation. During its development, we address two key challenges: significantly reducing smart contract gas costs and enabling fully distributed IPFS-based file storage. Additionally, we tackle three system issues related to security and sustainability. We have implemented a prototype of AGChain on Ethereum and Polygon blockchains, achieving effective security and decentralization with a minimal gas cost of around 0.002 USD per app upload (no cost for app download). The system also exhibits reasonable performance with an average overhead of 12%.
