Abstract

The Blockchain is a technique that prevents data from being manipulated and guarantees the integrity and reliability of the data by all participants in the network jointly owning and validating the data. Since the Blockchain characterized by security, scalability and transparency, it is used in a variety of fields including logistics, distribution, IoT and healthcare, including remittance. In particular, there is a growing interest in smart contract that can create different forms of contracts and automate implementation based on Blockchain. Smart Contract can be used to pre-programme contracts and are implemented immediately when conditions are met. As a result, digital data can be more reliable. In this paper, we are conducting a study on the smart contract design as a way to solve such problems as illegal misuse of funds on virtual currency, which has become an issue recently. Through this process, we applied the customer identification and money laundering prevention process using smart contract, and then check the possibility of preventing money laundering and propose the ASM (AML SmartContract Mechant) design.

블록체인은 네트워크 내의 모든 참여자들이 공동으로 소유하고 검증함으로서 데이터의 조작을 방지하고 무결성 및 신뢰성을 보장하는 기술이다. 블록체인은 보안성 및 확장성 투명성을 특징으로 하며 전 세계에서 이용가능하기 때문에 최근 송금을 포함하여 물류 유통, IoT 등 다양한 분야에서 활용되고 있다. 그 중에서도 최근에는 블록체인을 기반으로 하여 다양한 형태의 계약을 체결하고 이행을 자동화할 수 있는 스마트 컨트랙트에 대한 관심이 높아지고 있다. 스마트 컨트랙트를 활용하면 계약 사항을 미리 프로그래밍하여 작성하고, 조건이 충족되면 즉시 시행되기 때문에 디지털 데이터에 대한 신뢰도를 더욱 높일 수 있다. 본 논문에서는 스마트 컨트랙트 설계에 관한 연구를 진행하면서 최근 이슈가 되고 있는 가상화폐의 불법적 자금 악용 등의 문제를 해결하는 방안으로써, 스마트 컨트랙트 설계 방안에 대한 연구를 진행하였다. 이를 통해 고객확인(KYC:Know Your Customer)과 자금세탁방지 과정을 스마트 컨트랙트를 활용해 적용해 보았으며, 자금세탁방지의 가능성을 확인 및 ASM(AML SmartContract mechanism) 설계 방안을 제시해보고자 한다.
