The wholesale central bank digital currency (CBDC) sample application can support transaction scenarios between a central bank and other financial institutions.

The wholesale CBDC sample represents the life cycle of a wholesale CBDC token. The sample specification file uses the extended Token Taxonomy Framework standard that is supported by Blockchain App Builder. The generated chaincode includes methods from initializing a wholesale CBDC token, account operations, and role assignments to minting, transfers, and burning of CBDC tokens. It also provides notary accounts for approving minting, transfers, and burning operations, and it supports compliance through account-level daily limits and auditing procedures.

The wholesale CBDC solution comprises the following downloadable packages.

• Blockchain App Builder specification file
• Pre-built wholesale CBDC chaincode
• Wrapper APIs for CBDC setup and lifecycle operations
• Oracle Database view definitions for columnar views of the JSON transaction data in rich history database tables and use by analytics workbooks
• A sample application using Oracle Visual Builder, and a sample Oracle Analytics dashboard

To get the wholesale CBDC packages, in the Oracle Blockchain Platform Digital Assets console click the Digital Assets tab and then select Wholesale CBDC.
