Islamic Development Bank Secures Second USPTO Patent for Blockchain
At the core of any blockchain network lies a consensus algorithm, the mechanism that enables decentralized participants to agree on valid transactions without relying on a central authority.
The newly patented Proof-of-Use (PoU) introduces a reciprocity-based approach to consensus. Under this model, participants validate others’ transactions in exchange for having their own transactions validated. This shifts network influence away from computational dominance or financial muscle and toward active participation and genuine utility.
Unlike traditional models such as Proof-of-Work (PoW) and Proof-of-Stake (PoS), PoU integrates users and validators into a single group, meaning only active users of the network can validate transactions.
Addressing Energy, Equity and Governance Challenges
Proof-of-Use is designed to address key shortcomings associated with existing blockchain consensus models.
Environmental Sustainability:
PoU eliminates the competitive “arms race” characteristic of PoW systems, where miners compete using massive computational power. By removing this feedback loop, the mechanism significantly reduces energy consumption.
Fairness and Equity:
While PoS models often favor participants with the largest financial holdings, PoU prioritizes participation and utility over wealth concentration. This reciprocity-based validation framework reduces the risk of network capture by dominant financial actors.
Alignment of Interests:
By ensuring that users and validators are one and the same, PoU mitigates the divergence of objectives seen in other systems, where validators may prioritize rewards over the network’s broader purpose.

Designed for Development Finance
The reciprocity principle underpinning PoU is particularly relevant to development finance and Islamic financial systems. By limiting validation rights to active participants, the mechanism prevents external speculators, whose primary motivation may be validation rewards rather than transactional utility, from dominating the network.
This design is intended to support inclusive financial ecosystems aligned with ethical finance principles and long-term economic development goals.
Strengthening IsDBI’s Innovation Portfolio
Commenting on the milestone, Dr. Sami Al-Suwailem, Acting Director General of the Islamic Development Bank Institute, described Proof-of-Use as a key component of the Institute’s growing innovation portfolio.
“Our objective is to build a digital ecosystem to support inclusive growth and shared prosperity across Member Countries and communities,” he said. He added that the Institute is actively exploring strategic partnerships to leverage the innovative ecosystem in line with the IsDB Group’s 10-Year Strategic Framework, which emphasizes expanding Islamic digital financial services to broaden access to finance.
