Deep dives
Introduction to Silent Payments
Silent payments represent an innovative way to handle Bitcoin transactions that enhances privacy by allowing unique addresses for each transaction without needing interaction between payers and recipients. Unlike traditional Bitcoin addresses, which can reveal transaction history to anyone who sees the address, silent payments allow senders to generate new addresses for each payment. This method keeps payment information confidential, as recipients can only identify the transactions meant for them without exposure to external observers. The process involves advanced cryptographic techniques, where shared secrets are generated for each unique transaction, creating a more secure form of transaction handling.
