Project Khokha (2018)
The South African Reserve Bank ran a proof of concept with seven commercial banks to settle wholesale payments on a distributed ledger. It was a closed, bank-only trial with no consumer-facing currency. A second phase in 2022 moved on to tokenised bonds and privacy controls.
The trials showed the technology could handle interbank settlement at realistic volumes.
They left behind designs, technical contributors and a template for permissioned, institution-only digital money. eZAR is a commercial descendant.
eZAR's permissioned blockchain and multi-issuer structure come directly from this work, which is why it looks more like bank infrastructure than a crypto token.
