Tutorial 2. Enterprise Blockchain Solutions for Financial Services: Techniques and Challenges

Enterprise Blockchain Solutions for Financial Services: Techniques and Challenges

Ziyuan Wang, Donghai Liu and Yang Xiang (Swinburne University of Technology, Australia)

Abstract  

The fundamental of the financial services industry is to facilitate trusted transactions of value between multiple untrusted parties. Lately many financial institutions are considering using blockchain to enable more efficient cross-organizational collaboration in a distributed fashion, by eliminating costly intermediaries, manual processes, and error-prone actions.

Based on our industrial experience with Tier 1 banking and insurance clients, in this tutorial, we will provide an overview and hands-on knowledge sharing of enterprise blockchain solutions including shared KYC (Know Your Customer), bank guarantee, trade finance, and real-time insurance. We will demonstrate state-of-the-art techniques, highlight challenges, emerging trends, and share key lessons learned. In addition, we will provide overview in several popular blockchain platforms, and explain how they are applicable in developing enterprise-grade solutions for the financial services industry.

Keywords: blockchain, financial services, KYC, trade finance

Description

Blockchain technology is a natural fit for use in the finance services business as it can alleviate the pain points, particularly in cross-border payments, removal of manual processes and intermediaries, and acceleration in trade finance in a large geographic context. Due to the transparency and tamper- resistance nature of blockchain smart contracts, further benefits are realized through post-trade settlement and State/Federal regulatory reporting. According to a McKinsey report [1], approximately 90% of major financial institutions across Australia, Europe and North America have been experimenting and exploring the use of blockchain. However, the finance services industry is not yet ready to implement blockchain due to the limited availability of standards, technology maturity and ecosystem adoption.

In order to help accelerate the adoption of blockchain in the finance industry, this tutorial is a crucial step in demonstrating how various foundational building blocks can be aggregated through a series of design choices, to make the use of blockchain commercially viable. Specifically, through the tutorial, we will explore how to select the right blockchain platform, trust model, consensus protocol, and governance model. This will enable the use of blockchain more appealing to the finance industry and lay out a pathway for faster adoption. To support our case, we will be demonstrating representative practical examples where blockchain has already been applied in Tier 1 financial institutions with positive results.

This tutorial intends to serve as a valuable reference to a large audience including systems architects, blockchain practitioners, developers, and researchers. It can also be used as a roadmap for graduate students and academics, who are starting to research in the field of blockchain. The tutorial is also accessible by financial services industry participants, who have commenced exploring the use of blockchain in their domain. We expect the attendees to have at least the basic knowledge about databases, and core techniques behind blockchain.
