Ethereum co-founder Vitalik Buterin has proposed a "stealth address system" to improve transactional privacy on the Ethereum blockchain. In a research blog, Buterin wrote that privacy is "one of the largest remaining challenges in the Ethereum ecosystem." The stealth address system is based on a mechanism that would allow any Ethereum wallet to generate cryptographically obfuscated public addresses called "stealth addresses'' in order to receive funds in a private manner and access them using a special code called a "spending key."
