The Bank’s Experiment: A Groundbreaking Step

On Monday, the Bank of Israel made waves by unveiling the results from a pioneering lab experiment focused on user privacy and smart contracts within the realm of payments. This marked the central bank’s inaugural venture into the world of Central Bank Digital Currency (CBDC), and boy, does it have some juicy details!

The Car Sale: A Case Study

The first stage of the experiment involved modeling a car sale within a two-tier system, tapping into the capabilities of an intermediary payment service provider. The bank outlined that the payment provider took on the tough job of conducting Know Your Customer (KYC) and Anti-Money Laundering (AML) checks, all while juggling the responsibility of providing blockchain addresses. Who knew buying a car could be so high-tech?

In a plot twist—cue the suspenseful music—an NFT was issued to signify ownership of the car, proving that blockchain technology can do so much more than just making shiny digital cats. This NFT came to life even without a licensing authority, allowing the exchange of ownership through a smart contract. The seller could even hit the brakes on the deal if the conditions weren’t met. Talk about having your cake and eating it too!

The Dilemmas: Money and Contracts

The experiment shed light on significant questions about money management and the smart contracts themselves. One pressing issue was about the level of money held in digital form. To mitigate the risks of bank disintermediation—think massive cash withdrawals, followed by a digital frenzy—the idea of setting a daily limit was floated for inclusion in the smart contracts. One can only imagine the conversations around the virtual coffee machine about who gets to pull the trigger on such limits!

The second conundrum centered on the smart contracts. To curb misuse—both naughty and accidental—there’s a proposition to limit the ability to create these contracts to payment service providers alone. As regulations often go, the finer points of necessary oversight are still up in the air, raising questions about trust and control as well.

Establishing Identity and Privacy Matters

Another aspect of the experiment was the need for establishing user identities for effective KYC/AML processes. The second stage saw the creation of private digital shekels and regular digital shekels utilizing blockchain infrastructure in a zero-knowledge-proof environment. Yes, that’s a mouthful, but essentially, it’s about enabling privacy through eCash technology under various conditions—because who wouldn’t want privacy when handling their dough?

Policy Decisions and Future Implications

Moving beyond the cold hard tech, discussions highlighted that the level of privacy for digital shekel users will ultimately boil down to policy decisions. One question lingers: how do we balance the complete anonymity and freedom cash offers with the opaque nature of current electronic transactions? Where will the digital shekel fit in this spectrum? While Israel has been thinking about a CBDC since 2017, and even piloted one in 2021, these recent findings may redefine the trajectory forward.
