Abstract

High expectations are posed on the blockchain-based internet of things (IoT), in which IoT and blockchain technology is combined to obtain trust in the Internet, where trust appears impossible to obtain. However, applications of current blockchain-based IoT technology to real-world scenarios appears to be significantly more difficult owing to limitations regarding scalability and security. In this paper, the difficulties to implement blockchain networking technologies for IoT and digital businesses are investigated and practical solutions such as sharding, off-chain, de-idetification and P2P crypto-currency exchange are explored. In further work, a blockchain platform for IoTs which provides scalability and security will be implemented according to this research results, and compared with conventional blockchain platforms.

신뢰하기 어려운 인터넷 환경에서 신뢰를 확보하기 위해 블록체인 기술을 사물인터넷 (IoT Internet of Things)에 적용한 '블록체인 기반 IoT'에 대한 기대감이 높다. 그러나 현재의 블록체인 기반의 IoT 기술은 확장성과 보안성 측면에서 실생활에 응용하기에 한계가 있는 것으로 보인다. 본 논문에서는 최근 각광받는 사물인터넷 디지털 비즈니스를 실현시키기 위한 블록체인 네트워킹 기술의 확장성과 보안성 난제를 고찰하고 정책과 샤딩, 오프체인, 비식별화, P2P 암호화폐 교환 등의 기술적 해결 방안 도입을 제안한다. 후속 연구에서는 본 연구 결과를 바탕으로 보안성과 확장성을 보장하는 사물인터넷 블록체인 플랫폼을 구현하고 기존의 블록체인 플랫폼과 비교할 계획이다.
