Abstract

Blockchain is a technology that secures integrity and transparency by distributing and storing transaction details within multiple node networks. Recently, research is being conducted to secure integrity by applying blockchain to Bill of Lading (B/L documents) of monetary value. In this paper, we study a blockchain-based bill of lading system to improve usability. The shippers register the issued bill of lading on the blockchain, and banks in each country read it to conduct L/C transactions. The consignees receive the goods after completing certification with a quick response code (QR) containing the bill of lading information. Through this, shippers enjoy merits in that they can shorten the time and cost of sending shipping documents by mail and prove the integrity of the documents. The consignees have the advantage of being able to check the documents at the same time as they are registered and trust the transaction. Finally, on the bank side, the security of shipping documents is ensured and verification can be done quickly.

블록체인 기술은 거래를 투명하게 관리함으로써 중앙통제 없이 신뢰 가능한 P2P 거래를 가능하게 한다. 최근에는 금전적 가치를 지닌 선하증권(Bill of Lading, B/L서류)의 무결성을 확보하기 위해 블록체인을 적용한 연구가 진행되고 있다. 본 논문에서는 사용성 개선을 위한 블록체인 기반의 선하증권 시스템을 제안한다. 수출자는 선사로부터 발급 받은 선하증권을 블록체인에 저장하고, 은행에서 이를 조회하여 신용장 거래를 수행한다. 수입자는 선하증권 서류의 지문이 담긴 QR코드(Quick Response code)로 신원증명을 완료한 뒤 화물을 인도 받게 된다. 수출자는 우편으로 보낼 시간과 비용을 절약하고, 물품의 보안을 강화할 수 있다는 점에서 큰 효과를 거둘 수 있다. 수입자의 경우 선적 서류가 블록체인 네트워크에 등록되자 마자 서류를 열람할 수 있고, 신뢰를 바탕으로 거래를 수행할 수 있다는 이점을 갖는다. 뿐만 아니라 은행에서는 선적서류에 대한 검증을 더욱 신속하게 수행할 수 있다.
