Stealth Addresses offer a promising solution for privacy on Ethereum, where all transactions are public by default. Traditional privacy solutions like Tornado Cash only anonymize ETH or ERC-20 transactions, leaving NFT and other asset transactions exposed. Stealth Addresses, proposed by Ethereum co-founder Vitalik Buterin, address this by generating unique, private addresses for each transaction. Here’s how it works: a user can create a "Stealth Meta-Address" which is shared with the sender, who then calculates a Stealth Address for a private transaction. Cryptographic algorithms, including Diffie-Hellman key exchange, ensure only the recipient can control the assets in the Stealth Address. No public connection links this address with other accounts, preserving privacy. However, using assets in a Stealth Address requires gas fees, which can compromise privacy. To solve this, users might employ aggregators that obscure gas payments using a Chaumian blinding scheme. Recovery and management of Stealth Addresses remain complex, particularly for users with multi-signature wallets or accounts across multiple Layer-2 platforms. Zero-Knowledge Proofs (ZKP) technology could allow seamless management by letting users control multiple accounts through a single value, simplifying recovery without revealing links between accounts. In conclusion, Stealth Addresses represent a crucial step toward enhancing privacy on Ethereum. However, effective account recovery and management will depend heavily on advancements in ZKP technology.
