Public blockchain account information is completely transparent, which is a double-edged sword. Leading blockchains like Ethereum and Solana adopt an open ledger model, where all transactions and balances are visible to the public—sounds secure and controllable, but in reality, it exposes many issues.

Ordinary users often don't realize that their wallet addresses, asset sizes, and transaction histories are all recorded on the chain. Anyone with a blockchain data analysis tool can track your financial activities. It's like posting your financial statements on the street; hackers, competitors, and even strangers can trace your asset flow by associating wallet addresses.

The core significance of privacy protection technology is to bring financial transactions back to rationality—users should have the right to choose to protect their financial privacy. Truly usable privacy solutions not only need to ensure transaction confidentiality but also, on the premise of maintaining the transparency advantages of blockchain, provide participants with enough autonomy and security. Only then can the long-term healthy development of the Web3 financial ecosystem be promoted.
