Query: EdgeChain: Blockchain-based Multi-vendor Mobile Edge Application
  Placement   The state-of-the-art mobile edge applications are generating intense traffic
and posing rigorous latency requirements to service providers. While resource
sharing across multiple service providers can be a way to maximize the
utilization of limited resources at the network edge, it requires a centralized
repository maintained by all parties for service providers to share status.
Moreover, service providers have to trust each other for resource allocation
fairness, which is difficult because of potential conflicts of interest. We
propose EdgeChain, a blockchain-based architecture to make mobile edge
application placement decisions for multiple service providers. We first
formulate a stochastic programming problem minimizing the placement cost for
mobile edge application placement scenarios. Based on our model, we present a
heuristic mobile edge application placement algorithm. As a decentralized
public ledger, the blockchain then takes the logic of our algorithm as the
smart contract, with the consideration of resources from all mobile edge hosts
participating in the system. The algorithm is agreed by all parties and the
results will only be accepted by majority of the mining nodes on the
blockchain. When a placement decision is made, an edge host meeting the
consumer's latency and budget requirements will be selected at the lowest cost.
All placement transactions are stored on the blockchain and are traceable by
every mobile edge service provider and application vendor who consumes
resources at the mobile edge.
