Blockchain for trade facilitation:Ethereum, eWTP, COs and regulatory issues

Blockchain is a peer-to-peer (P2P) technology that records and verifies transactions in a decentralised, cryptography-secure manner. Blockchain applications can globally manage records of any sort, such as import-export declarations, invoices, bills of lading (BLs) and certificates of origin (COs). It is a promising technology for several areas, including international trade. This paper presents blockchain, comments on blockchain platforms such as Ethereum, gives examples of private sector initiatives, shares an idea for a CO blockchain application, and discusses regulatory issues. In doing so, the paper aims to attract attention for blockchain in international trade
