Bank of Israel tests smart contracts and CBDC with privacy

English Jun 28, 2022

Last week, the Bank of Israel released the results of an experiment that tested the use of user privacy protocol and the use of smart contracts in payments. This was the central bank's first technology experiment with a CBDC.

The first stage of the experiment modeled the sale of a car within a two-tier system with an intermediary payment service provider. The bank said the service provider completed KYC/AML verifications and provided the necessary blockchain addresses. An NFT was issued to show ownership of the car in the absence of a licensing authority to effect the transfer. A smart contract exchanged the seller's NFT and the buyer's money, with the seller retaining the right to cancel the transaction if conditions, such as the price of the car, were not met.

The experiment drew attention to two issues. The first was the amount of money held in digital form. To avoid bank disintermediation, a daily limit was suggested that could be realized via smart contracts. The second question concerned the smart contract itself. To reduce the chances of intentional or unintentional misuse of smart contracts, it was suggested that the ability to write smart contracts on the blockchain should be limited to the payment service provider, but the extent of oversight required in this case remained undecided.

In addition to technical issues, it was noted that the level of privacy of digital shekel users will be a matter of policy. The Israeli government has been considering issuing CBDCs since 2017 and conducted a pilot test in 2021.
