Introduction of World's Largest DVT Protocol "SSV Network" to Institutional Ethereum Management Infrastructure

BITPOINT Japan Co., Ltd. (Brand: BITPOINT; Headquarters: Minato-ku, Tokyo; President: Ken Nakata; hereinafter "the Company"), a crypto asset exchange operator under the SBI Group, has commenced a partnership with SSV Labs (CEO: Alon Muroch), the developer and operator of the "SSV Network," a Distributed Validator Technology (DVT) protocol for Ethereum.

SSV Labs joins the three-party collaboration between Def consulting Co., Ltd. (Ticker: 4833; Headquarters: Minato-ku, Tokyo; President: Yuta Shimomura; hereinafter "Def consulting") and P2P.org, which was announced on December 22, 2025, expanding the partnership to four companies.

Def consulting is promoting an "Ethereum Treasury Strategy," incorporating Ethereum (ETH) into its balance sheet to aim for medium-to-long-term enhancement of corporate value.

As one of its management methods, a mechanism for continuous reward acquisition through the Company's staking service has been established. Previously, the Company handled the acquisition, custody, and staking infrastructure for Ethereum, while P2P.org managed validator operations.

With the addition of SSV Labs, DVT technology will be introduced to P2P.org's validator operations, aiming for further improvements in the safety and profitability of Def consulting's Ethereum management.

Objectives of Introducing DVT

1. Strengthening Operational Safety

DVT (Distributed Validator Technology) decentralizes the key management and operation of validators among multiple independent operators. Even if a single operator or node experiences a failure, the overall operation of the validator does not stop. By eliminating single points of failure, the risk of slashing (penalties) and missed rewards can be minimized.

2. Expanding Profit Opportunities

The SSV Network features an incentive program for network participants, allowing them to receive network participation rewards in addition to standard Ethereum staking rewards. This structure ensures that the technological implementation intended to increase safety simultaneously leads to improved profitability.

Overview of SSV Network

SSV Network is a fully decentralized, open-source staking protocol for Ethereum with DVT at its core. By distributing validator operations across multiple independent operators, it eliminates single points of failure and enhances the safety and decentralization of staking. With a Total Value Locked (TVL) exceeding $15 billion, a staking track record of over 6 million ETH, and more than 1,800 participating operators, it is the world's largest protocol in the Ethereum DVT field.

Representative Comments

■ Yuta Shimomura, President and CEO of Def consulting Co., Ltd.

"Our strategy places Ethereum at the core of our balance sheet, making staking rewards a pillar of our revenue. By incorporating DVT technology into our management infrastructure, we have established a system where validators will not stop even in the unlikely event of a failure. Additionally, we expect supplementary rewards through the SSV Network incentive program. I believe the most significant feature of this four-party collaboration is that profit opportunities expand as a result of increased safety. Based on this structure, we aim to steadily build medium-to-long-term value for our shareholders..."
