However, their stringent energy budget also introduces challenges that must be addressed before such devices can be utilized effectively. Energy-efficient, intermittence-aware operation is one of such challenges. In this work, we present an approach to tackle this issue in the context of executing a proof-of-work algorithm on a low-power computation core. Our proposed techniques significantly improve the computation efficiency even in the face of frequent and unpredictable power loss events, a characteristic of batteryless, intermittently operating devices.enbatteryless operation | Hashcash | proof-of-work algorithm | SHA-1Technology::600: TechnologyCompetition: Work Smarter, not Harder: Towards a Sustainable IoTConference PaperConference Paper
