(English Abstract) |
As an emerging platform for decentralized applications, blockchain has gained popularity in recent years. With its ability to quickly establish a self-organized data management platform for various decentralized applications, permissionless blockchain creates a framework to support seamless data trading for various mobile crowdsensing tasks by using executable smart contracts. In this regards, the task of solving resource extensive cryptographic puzzle for a new block of transactions in the blockchain network, known as “mining”, can be offloaded to the edge infrastructure by the contract providers, referred as virtual miners. In this work, we design a flexible infrastructure for the resource constraint users to trade data autonomously, in an affordable and secure manner by exploiting economic interaction between virtual miners and the blockchain network. The users can interact with the smart contract provider, who can independently design smart contracts and build decentralized applications, namely DApps, by themselves without the trusted intermediaries. We facilitate the user requirements with the smart contract providers, and formulate a utility maximization problem to adapt the computational resource sharing policy between the competing smart contract providers in the blockchain network to construct DApp infrastructure. Simulation results characterize the optimal trading point that maximizes the overall network utility. |
