Research output: Chapter in Book/Report/Conference proceedingConference contribution


This is an extended abstract for the research demo of a novel hardware-assisted scalable blockchain called PUFChain. This work presents a scalable energy-efficient private/permissioned blockchain (integrated with Physical Unclonable Functions or PUFs) which can be deployed in the IoT. PUFs have a multiple of roles in the blockchain: higher security, lower latency, and reduced energy consumption. Experimental validations of PUFChain show a transaction time of 198ms. To the best of authors knowledge this is the first ever work that presents a comprehensive framework integrating PUFs in a blockchain.
