IsDBI Secures US Trademark Office Patent for “Proof-of-Use” Blockchain Consensus Model

INTRODUCTION

The Islamic Development Bank Institute (IsDBI) has been awarded a new patent by the United States Patent and Trademark Office (USPTO) for an innovative blockchain consensus mechanism known as “Proof-of-Use.” The patent, officially granted on 10 February 2026, represents the institute’s second USPTO patent and its fifth overall intellectual property registration.

The development highlights the institute’s ongoing focus on advancing financial technology solutions designed to support economic development and the expansion of Islamic digital finance.

KEY DETAILS

The newly granted patent, numbered 12,548,031 B2, protects a novel method for achieving consensus within distributed ledger technology (DLT) systems, including blockchain networks. The patented approach, referred to as Proof-of-Use (PoU), proposes an alternative framework for validating transactions across decentralized networks.

In conventional blockchain architectures, consensus algorithms ensure that all network participants agree on the validity and sequence of transactions without relying on a centralized authority. The PoU model introduces a reciprocity-based mechanism in which network participants validate other users’ transactions in exchange for their own transactions being validated.

Under this structure, individuals who actively use the network also serve as validators, aligning participation and governance within the same group. This differs from traditional models such as Proof-of-Work and Proof-of-Stake, where transaction validators often operate separately from ordinary users.

The approach also aims to reduce energy consumption associated with blockchain validation processes. By removing the competitive computational race characteristic of Proof-of-Work systems, the PoU model is designed to operate more efficiently while maintaining network security.

According to the institute, the mechanism also seeks to address concentration risks commonly associated with Proof-of-Stake frameworks, where validation influence may correlate with the size of financial holdings.

Further details about the patented system are available through the official announcement published by the institute on the Islamic Development Bank Institute website.

INDUSTRY CONTEXT

The Islamic finance industry has increasingly explored the application of blockchain and distributed ledger technologies to enhance transparency, efficiency, and financial inclusion. Institutions such as the Islamic Development Bank Institute have been active in researching technological frameworks that align with the ethical and developmental objectives of Islamic finance.

Innovations in consensus mechanisms are particularly relevant as financial institutions evaluate blockchain infrastructure for cross-border transactions, digital asset management, and financial inclusion initiatives.

INDUSTRY IMPACT

The patent strengthens the institute’s position in the fintech research landscape while contributing to ongoing discussions about sustainable and equitable blockchain governance models. By prioritizing active participation rather than computational power or financial stake, the Proof-of-Use mechanism may offer an alternative architecture suitable for development-focused financial networks.

Such innovations could support future digital financial platforms aimed at improving access to financial services across emerging markets and member countries of the Islamic Development Bank Group.
