Using Confidential Transactions for Selective Disclosure
The Confidential Transactions element offers cryptographic privacy over the amounts of an asset used in
transactions on a sidechain. There are many use cases for selectively disclosure some parts of
a transaction, for example to an auditor.
The Blinding Key
The “Blinding Key” is a shared value between the participants that grants them
access to the cryptographically-concealed amount. By sharing this key (out of
band), external parties will have the ability to “decrypt” the transaction.
In order to execute a third-party audit of transaction amounts, the blinding key
can be exported by the receiver and passed on to the auditor.
