Elastic Smart Contracts in Blockchains

In this paper, we deal with questions related to blockchains in complex Internet of Things (IoT)-based ecosystems. Such ecosystems are typically composed IoT devices, edge cloud computing software services, as well people, who decision makers scenarios such smart cities. Many decisions analytics can be based on data coming from sensors, and people. However, they different levels abstraction granularity. This poses a number challenges when multiple used together contracts. work proposes apply our concept elasticity contracts thereby enabling between the context IoT. We propose reference architecture for Elastic Smart Contracts evaluate approach city scenario, discussing benefits terms performance self-adaptability solution.
