Digital Platformer Co., Ltd. Begins Proof of Concept for RWA (Real World Asset) Trading Platform Using XRPL

Digital Platformer Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Kazuyuki Matsuda; hereinafter 'the Company') announces the commencement of a proof of concept for an RWA (Real World Asset) trading platform that enables the management and trading of real-world assets on a blockchain.

In this proof of concept, as the first use case, the Company will implement an initiative to issue digital certificates corresponding to green electricity and record their transaction history on the blockchain.

Proof of Concept for RWA Trading Platform Using XRPL

Overview of the Proof of Concept

This platform is a mechanism that manages asset information and rights existing in the real world on a blockchain, enabling global trading and integration with on-chain finance. The base chain employs XRPL (XRP Ledger), which excels in speed, reliability, and scalability. The Company aims to realize a platform capable of handling the digital circulation of diverse assets by building token issuance and distribution functions linked to individual RWAs.

In this proof of concept, the 'Multi-Purpose Token (MPT)' function on XRPL is utilized. MPT is a token standard that allows the management of multiple quantities under a single token ID. In this project, digital certificates corresponding to green electricity are issued, and the amount of electricity is expressed as an MPT balance, enabling issuance and distribution control at a finer granularity than before.

Furthermore, by linking attribute information such as power generation time, generation type, and generation region as metadata on-chain, the transparency and traceability of electricity origin information are improved.

Issuance and Distribution of Digital Certificates for Green Electricity

Mechanisms for proving the environmental value of electricity derived from renewable energy are already widely used both domestically and internationally. On the other hand, conventional certificates are often managed on a monthly or annual total basis, which can lead to discrepancies with the actual timing of electricity usage, raising concerns about so-called 'greenwashing,' where environmental considerations are promoted beyond reality.

Against this background, initiatives for electricity certification emphasizing real-time capabilities, such as 'EnergyTag,' are progressing globally.

The Company, in collaboration with I-Grid Solutions Co., Ltd. (Headquarters: Minato-ku, Tokyo), will begin a proof of concept that divides the electricity generated by solar power facilities operated by I-Grid Solutions across Japan into 30-minute intervals and records the generated amount as time-limited digital certificates on the blockchain.

This initiative aims to realize a mechanism that links the timing of power generation and consumption with higher precision by shortening the issuance unit of certificates and setting expiration dates. This will promote the distribution of environmental value aligned with actual electricity usage and advance the verification of a new operational model with higher consistency with real demand compared to conventional certificates.

Furthermore, the issuance, management, and distribution infrastructure for digital certificates in this proof of concept is built upon the Company's accumulated technical and operational know-how in the fields of digital ID, digital currency, and blockchain. To enhance the effectiveness of the proof of concept, the Future Photonic Network Open Research Center at Keio University has been engaged as an advisor, promoting the project under specialized expertise in the electric power field.

Future Outlook

The Company will verify the effectiveness of RWA utilization in the green electricity field through this proof of concept and, looking ahead, plans to expand into various asset areas such as carbon credits, environmental value, digital securities, and regional assets.

Going forward, the Company will continue to work towards realizing new value circulation in society by building a reliable and highly transparent digital transaction infrastructure utilizing blockchain technology.
