Establishing a Security Working Group at JCBA

The Japan Crypto Asset Business Association (JCBA) has officially announced the formation of a new working group (WG) focused on the creation of a preliminary Security Guidebook. The initiative is chaired by Shinya Tsuchida, the CEO of Next Finance Tech. This step reflects a significant move in the effort to bolster security measures within the rapidly evolving cryptocurrency and blockchain industry.

Purpose and Objectives

Recognizing the need for enhanced security in managing crypto assets, JCBA has identified this as a critical challenge for the industry's future development. Following last year’s major cryptocurrency outflow incident involving domestic exchange operators, the Security System Subcommittee collaborated with the Japan Cryptocurrency Trading Association to provide insights on the security landscape and response measures to the joint meeting of the Liberal Democratic Party's Digital Society Promotion Headquarters and the Financial Research Council. This led to efforts in reinforcing cyber security across the entire sector, culminating in the establishment of the JPCrypto-ISAC.

Moreover, the landscape of crypto assets has expanded significantly, with new businesses entering not only in cryptocurrency exchanges but also in services related to NFTs, stablecoins, and security tokens. Each of these services brings distinct risks and security considerations. The WG aims to address the rising need for enhanced security measures relevant to all web3-related service providers, ensuring that information is organized based on the specific services provided. This will assist in business planning while also benefiting regular users through a well-organized collection of crucial security information.

This initiative seeks to improve security for businesses, users, and the cryptocurrency and blockchain industry as a whole.

Comments from Chair Shinya Tsuchida

With the rapid advancement of regulatory frameworks surrounding crypto assets in Japan, there is an ongoing redefinition of what cryptocurrency signifies as a means of contributing to national wealth formation. Thus, improving security measures across the industry has become an urgent necessity. Considering the influx of new entrants and previous outflow incidents, the JCBA Security Subcommittee has established a working group aimed at compiling practical security guidelines that include not just cryptocurrency exchange operators but also businesses related to NFT services, security tokens, and other web3 ventures. This initiative will broaden the security literacy across the industry.

In the future, collaborative efforts are planned with other organizations and academic institutions to promote the safe proliferation and sustainable development of crypto assets and web3-related enterprises.

About the Security System Subcommittee

The primary goal of the Security System Subcommittee is to provide a platform for sharing knowledge related to security and systems, irrespective of whether members are exchange operators, and to offer recommendations to regulatory authorities.
