Abstract
This paper shows critical points of consideration regarding the adoption of blockchain technology
(DLT; Distributed Ledger Technology) in enterprise IT systems, beyond just financial services, based on selected trials in the Japanese financial services industry. After reviewing the history of blockchain initiatives in the Japanese services industry, this paper describes selected proof-of-concepts and experiments by Japanese financial institutions focusing on four main themes; in-house coin, interbank transfer, know-your-customer (KYC), and global trade. We discuss the background of the shift in interest from Bitcoin remittances to private-blockchains and the similarities between the trust point (Oracle) in DLT and the functions provided by financial institutions.
