Introduction

OpenBook 7 (“OB7”) is a professional trading platform for foreign exchange and contracts for difference, developed and operated by The DRU. Its core innovation lies in delivering best-execution transparency and comprehensive, independent auditing capabilities.

​

Operating directly on The DRU’s proprietary rails, OpenBook 7 integrates with the world’s first trading platform architecture built on a tokenless, permissioned blockchain: The DRU FX Blockchain — without the use of any cryptocurrency or tokens.

​

Verification

OpenBook 7 leverages the DRU FX Blockchain for robust verification. Certified Public Accountants and Global Investment Performance Standards (GIPS)-compliant firms will operate independent validator nodes in a permissioned network. This federated architecture distributes data verification and enables on-chain confirmation of ingested records on our public ledgers, or directly from the trading platform.

​

Through the platform, end users can independently verify and review the following information at any time:

​

• The precise extent to which a broker/firm is trading against (or with/for) them, including hedged positions, associated profit and loss (PnL) of the broker/firm’s market position, and detailed visibility into each hedge;

• Every historical market quote at the exact time it was given, fully replayable with millisecond precision;

• Account-level statistics at exact millisecond intervals (e.g. equity/balance at a specific date, hour, minute, or second);

​

and additional data sets as required.

​

All information resides immutably on the blockchain ledger following ingestion and consensus among validator nodes, providing absolute proof, replayability, and auditability.

​

Impact

OpenBook 7 is expected to deliver a transformative advancement for the global foreign exchange industry. The platform will enable institutional and retail participants to:

​

• Independently verify the track records of publicly promoted traders and trading strategies;

• Monitor A-book and B-book practices of brokerage firms through verifiable, post-facto records; and

• Provide firms and brokers with a powerful, independently verifiable tool that can be commercially licensed to support business development, marketing, and client acquisition.

​

Solutions

To support institutions adopting this new standard, The DRU will extend full access to its proprietary infrastructure to all commercially licensed partners. This includes:

​

• Secure access to private blockchain segments dedicated to settlement, enabling real-time payments to traders with zero risk of institutional undercapitalization;

• Integration with The DRU’s established banking relationships and proprietary debit solutions, allowing enhanced UX for clients when spending their rewards;

• Dedicated A-book management infrastructure, purpose-built for brokers and proprietary trading firms to operate their books responsibly and profitably while avoiding conflict of interest with client interests;

• Comprehensive ongoing support to address any operational or technical requirements arising from the adoption of this technology.

​

Commercial Licensing

Commercial licensing of OpenBook 7 will commence in April 2026.

​

Licensing is offered with no upfront fees. All platform maintenance, updates, and infrastructure management are handled entirely in the cloud by The DRU, eliminating operational overhead for licensees.
