COTI’s CBDC-Based Marketplace for RWAs Takes Center Stage at Bank of Israel Digital Shekel Challenge

As a seasoned analyst with years of experience in the fintech and blockchain industry, I find COTI‘s participation in the Bank of Israel’s Digital Shekel Challenge particularly noteworthy. In my view, COTI’s decentralized marketplace for trading RWAs presents a compelling use case for CBDCs and showcases the potential of blockchain technology in this space.


As a researcher involved in the field of blockchain technology, I am excited to share that COTI, a privacy-centric blockchain platform, recently showcased its proposal for a decentralized marketplace specifically tailored for trading Renewable Water Assets (RWAs) at an influential gathering organized by the Bank of Israel. This event, known as The Digital Shekel Challenge, aimed to delve into practical applications of Central Bank Digital Currencies (CBDCs). Remarkably, COTI was the sole blockchain technology invited to join this contest, which officially began in August and concluded on October 31.

COTI Tackles CBDCs

A number of prominent fintech companies and payment providers such as PayPal and Fireblocks have formed teams to participate in the Digital Shekel Challenge. COTI’s submission, a decentralized platform for event tickets, demonstrated the potential for a digital shekel – a central bank-issued digital currency – to act as an intermediary for exchanging local currency with that of another country.

In this presentation by COTI, they showcased a concept that leverages smart contracts to make intermediaries redundant. This hypothetical marketplace would significantly decrease instances of ticket fraud and offer numerous other uses, such as facilitating the trading of real-world assets. Remarkably, Central Bank Digital Currencies (CBDCs) could be integrated into these transactions as well. You can watch the demonstration here: [insert link]

The peak of the competition took place at the Tel Aviv Stock Exchange on October 31, with COTI showcasing its decentralized marketplace alongside 13 other project groups. COTI’s involvement in the Bank of Israel’s Digital Shekel Challenge demonstrates the possible use of blockchain technology within central bank digital currency (CBDC) projects.

The fine details of the task required participants to create scenarios that would handle connections between the digital shekel, other payment methods, and cash, along with employing sophisticated features like sub-wallets, conditional transactions, and fractional payments. Additionally, it involved integrating multiple technologies for payment using the digital shekel.

In simpler terms, project groups had to employ an API (Application Programming Interface) layer to offer various functionalities needed by payment service providers. Solving these essential issues is crucial before any national bank can start developing a Central Bank Digital Currency (CBDC). Therefore, the work done in this sandbox competition has practical implications for the real world.

Bringing Private Transactions to Public Chains

COTI’s technology, particularly its garbled circuit protocol, fits perfectly with the privacy standards of digital currencies. By employing this cryptographic method, COTI offers a platform where a Central Bank Digital Currency (CBDC) can achieve its objectives without infringing on individual privacy. This feature is crucial for future CBDC designs, especially for governments that emphasize privacy in digital transactions.

As an analyst, I’ve been closely observing COTI’s pioneering role in the realm of web3 advancements, specifically focusing on the development of blockchain applications with inherent privacy features. The innovative technology they employ, known as Garbled Circuits, is a cryptographic protocol that proves particularly effective for cases like Central Bank Digital Currencies (CBDCs).

As a analyst, I am closely observing the global shift towards Central Bank Digital Currencies (CBDCs), with over 40 such projects underway. However, it’s crucial to address the valid privacy concerns that have surfaced along with this transition. The technology that can effectively address these concerns while maintaining compliance is poised for widespread acceptance as CBDCs transition from theory to practical reality.
