    1. A ring signature is created when the sender of a transaction is mixed together with a random collection of other IDs that basically serve as a decoy. This process produces a unique digital signature for the transaction, but it blurs the identity of the real sender.

    2. Zero-knowledge proofs present the solution. The enterprise can prove it's the recipient of upcoming payments without revealing all the business details it may rightly want to keep private.

    3. Another HD wallet solution to generate privacy is a so-called merge and re-split operation. In this example, several entities anonymously submit new addresses to a smart contract. The contract collects the same amount from each party, let's say it's 100 bitcoins each. Then the contract re-deploys the amount to the new addresses.

    4. An HD wallet uses algorithms to create a new public-private key pair for each transaction or piece of a larger trade. This thus would allow a user to have a virtually infinite number of public addresses all derived from a single master seed phrase, making their identity difficult to trace.
