THXLAB and ECQ Launch PoC Using LastEvidence for Financial Security

THXLAB, a Tokyo-based company led by CEO Kotaro Kondo, has announced a pioneering Proof of Concept (PoC) utilizing its blockchain tracing platform, LastEvidence, in partnership with Singapore's ECQ. Scheduled to commence on July 1, 2026, this initiative aims to strengthen security measures in the financial sector by implementing blockchain technology within major securities firms in Japan.

Introduction to LastEvidence

LastEvidence, a blockchain forensic tracing preservation solution developed jointly by THXLAB and ECQ, serves as a crucial tool for enhancing data integrity within financial transactions. By generating logs and recording them in real-time on an offsite blockchain (THXNET), LastEvidence aims to swiftly restore and verify the data, should cyber-attacks result in log tampering or deletion. This PoC is positioned as a vital step towards the societal implementation of LastEvidence, aiming to achieve a transparent audit trail that can objectively confirm "who did what, when, and with what authority."

Implementation Details of the PoC

The PoC will be conducted from July 1, 2026, to the end of August 2026, focusing on specific business processes within the trading systems of major domestic securities companies. The stakeholders involved in this PoC include:

• - Major Domestic Securities Firms
• - TradeWorks, Inc. (a key collaborator and partner)
• - ECQ
• - THXLAB

Key Validation Areas

1. Tampering Detection Validity: The effectiveness of detecting alterations in system logs, particularly after unauthorized intrusions from malware or similar threats, will be examined.
2. Integrity and Preservation of Trace Data: Assessing whether the integrity of recorded data is upheld, ensuring compliance and reliability in audit traces.
3. System Integration and Practicality Assessment: Evaluating the technical feasibility of integration with existing systems and the impact on system load and operations during log collection and recording activities.

Roles and Responsibilities

Background and Significance

The risks associated with ransomware and cyber-attacks that can delete, alter, or encrypt logs and backups are intensifying within the financial and securities sector. A recent revelation indicated that widely used SIEM platforms are vulnerable to log and alert tampering by cyber attackers, raising concerns that the foundational detection and storage systems themselves may become targets. In this precarious environment, preserving the authenticity of trade records is paramount for compliance and overall system integrity within the industry. LastEvidence presents a pragmatic approach to adding an additional layer of evidence without undermining existing system investments.

Upcoming Presentation at WebX2026

On July 13 and 14, 2026, THXLAB and TradeWorks will participate in WebX2026 at the Prince Park Tower in Tokyo. Masakatsu Saito, the President of TradeWorks, will engage in a panel discussion on the current state and future prospects of on-chain finance, alongside a demo exhibit of LastEvidence.

Future Prospects

Following the PoC's outcomes, THXLAB plans to explore the future applicability of LastEvidence in financial operations. By combining LastEvidence with the offsite blockchain infrastructure provided by THXNET, THXLAB aims to establish a cyber-resilient financial environment that retains the authenticity of traces even against cyber threats.
