The Islamic Development Bank Institute (IsDBI) has achieved a significant milestone by securing Patent No. 12,548,031 B2 from the U.S. Patent and Trademark Office (USPTO) on February 10, 2026. This patent represents the Institute”s second from the USPTO and its fifth overall, solidifying its role as a pioneer in financial technology aimed at economic development and Islamic finance.
The patented technology introduces a novel method for reaching consensus in Distributed Ledger Technology (DLT), specifically within blockchain ecosystems. This method, termed Proof-of-Use (PoU), signifies a transformative shift in the validation and security of transactions.
In any blockchain framework, the consensus algorithm is crucial as it defines how participants in the network agree upon valid transactions, their sequence, and the overall integrity of the decentralized ledger without requiring a central governing body. PoU employs a reciprocity-based strategy where participants validate each other”s transactions in return for having their own transactions confirmed, effectively linking the influence within the network to actual engagement rather than mere computational power or financial investment.
Distinct from conventional consensus mechanisms like Proof-of-Work (PoW) and Proof-of-Stake (PoS), PoU”s foundation lies in the principle of reciprocity. This model fosters a community where:
- Users and Validators are Unified: Only those actively engaging with the network possess the authority to validate transactions. This contrasts with PoW and PoS systems, which often create a divide between validators and users, leading to conflicting goals.
- Environmental Sustainability: By abolishing the competitive “arms race” characteristic of PoW, PoU mitigates the excessive energy consumption commonly associated with these algorithms.
- Fairness and Equity: PoU combats the biases prevalent in PoS systems that tend to favor wealthier participants. By prioritizing reciprocity, it emphasizes active participation over financial dominance.
The principle of reciprocity inherent in PoU is particularly advantageous for development finance as it minimizes the risk of network control by external speculators whose primary aim is validation rewards rather than facilitating transactions.
Dr. Sami Al-Suwailem, Acting Director General of the IsDB Institute, commented, “The Proof-of-Use mechanism is an important component of the Institute”s innovation portfolio. Our objective is to build a digital ecosystem to support inclusive growth and shared prosperity across Member Countries and communities.” He further noted that the Institute is pursuing strategic partnerships to leverage this innovative ecosystem, aligning with the IsDB Group”s 10-Year Strategic Framework aimed at enhancing Islamic digital financial services for broader financial access.
