This is a Solidiy code for a privacy-preserving Smart-contract. For simplicity we assume that investors trade one type of share.

1- Deploy the smart-contract to one of the Ethereum networks, or simply use Ganache.

2- Add anonymous investor accounts (CSD role) by calling addAnonymousNin () function

3- Simulate a trade by calling buyShares and sellShares function.

Or you can simply call execute() function: contains an already embeded example.

This is part of a research work made at Hamed Bin Khalifa University (HBKU)
