"The joint initiative, announced April 20, 2026, adds Digital Asset Holdings as the fourth participant. Digital Asset supplies the Canton Network platform, which was built specifically for institutional finance."
"At its core, the PoC tests whether rights in JGBs, transferred under Japan's Act on Book-Entry Transfer of Corporate Bonds and Shares, can move across a blockchain without losing their legal standing under existing Japanese law."
"Participants will also check whether changes to book-entry transfer records can happen in real time within a multi-institution account structure. The four partners aim to move JGB collateral posting and substitution from a process tied to business hours into one that runs around the clock."
Japan Securities Clearing Corporation, Mizuho Financial Group, and Nomura Holdings initiated a proof-of-concept trial on April 20, 2026, to manage Japanese government bond collateral using the Canton Network blockchain. The trial aims to enable 24/7 real-time cross-border collateral settlement, moving away from traditional business hours. The project, supported by Japan's Financial Services Agency, will assess the legal transfer of rights in JGBs on blockchain and the feasibility of real-time updates in a multi-institution account structure. The trial will conclude in September 2026.
