Overview

Mission

Datachain is a deep-tech company engaged in the development of blockchain technologies for significant social impact areas such as "cross-border payments" used in business-to-business transactions. For example, the market for international remittances by banks, a process in cross-border payments, sees more than 150 trillion yen in transactions from domestic sources alone. This market has many stakeholders, high fees, and slow settlement times. We believe that blockchain technology can provide a reliable and secure payment solution that is both cost-effective and fast.

To this end, we are promoting platform development in the blockchain x finance domain through capital participation in "Progmat." In these efforts, we are undertaking the significant challenge of introducing blockchain technology into the existing bank cross-border payment schemes.

Progmat, Inc is a joint venture led by Mitsubishi UFJ Trust Bank, with participation from Mizuho Trust Bank, Sumitomo Mitsui Trust Bank, SMBC, NTT Data, and Datachain, all contributing to the social implementation of blockchain technologies such as stablecoins, sharing various roles. Datachain participates as a technology company with blockchain expertise.

This requires the development of several new services and systems, such as web applications for corporate settlements, proprietary blockchains, and integration with bank systems. We aim to launch these services quickly to maintain Japan's regulatory advantage in blockchain-enabled financial services compared to other countries.

*What are Stablecoins?
Stablecoins are digital currencies, such as "1 coin = 1 yen," tied to fiat currencies at a 1:1 value, used as a digital payment method.

 

Progress So Far

Datachain was founded in 2018 and has been involved in R&D in the area of "Interoperability" connecting different blockchains. We plan to launch an application developed through this R&D, "TOKI," in 2024.
We have also focused on open-sourcing our R&D results.

Collaboration with Progmat has given us a promising outlook on overcoming the business challenges of developing new solutions in collaboration with domestic banks.
We are currently using these technology assets to develop blockchain technologies for cross-border payment systems.
You will lead a mission that has a significant impact on technology and business, aiming to update the massive financial infrastructure of cross-border payments and establish a de facto standard.

 

Job Description

In this position, you will be responsible for the development of web applications for corporate payment products using stablecoins.
As for the development phase, development will start around the summer of 2024, so you will be able to be involved from the architectural design and technology selection.
