Abstract-This article examines options to improve efficiency and prevent counterfeits
related to distributor-to-consumer (D2C) transaction processing in the consumer
electronics (CE) industry. Particularly, we propose a smart contract enabled D2C model
that provides a blueprint for the smart integration of CE transactions. To the best of our
knowledge, the proposed CE-specific D2C model is among the very few attempts of
leveraging smart contracts to enhance the efficiency and efficacy of CE applications.

& BLOCKCHAIN, as a technological innovation of
distributed storage, peer-to-peer transaction
model, consensus mechanism, and encryption
algorithm, has been actively explored by quite a
number of governments, organizations, and
even individuals. Blockchain has disrupted the
traditional practice of the business transaction
processing, bringing about new opportunities
for value realignment.
Smart Contract, as a digitally signed, decentralized computer protocol between two or
more parties, is driving a new wave in upgrading

blockchain from "Blockchain 1.0," which is
mainly characterized by executing the transactions of bitcoin and other cryptocurrencies, to
"Blockchain 2.0," which is marked as various
blockchain-enabled applications beyond bitcoin.1 So far, blockchain and smart contract are
being explored by risk-tolerant start-ups and
innovative governments. At the time of this writing, the financial sector generates most of the
successful blockchain-based showcase applications. However, applications to the consumer
electronics (CE) industry are rare.2
The main contribution of this paper is to
develop a CE-specific transaction processing
model of applying blockchain-enabled smart
