The Necessity of Privacy in Blockchain Transactions
Blockchain technology, primarily known for its transparency, poses privacy challenges that must be addressed. The common misconception that blockchain inherently supports anonymity overlooks its transparent nature, which can expose sensitive transaction details. For example, when using stablecoins like USDC or USDT for personal purchases, all transaction participants and amounts become public, allowing tracking of individuals' financial activity. This situation creates a need for privacy solutions, particularly in everyday transactions where users desire confidentiality, such as purchasing gifts or groceries.
