Buterin proposed to improve the privacy of the Ethereum network

Ethereum co-founder Vitalik Buterin has proposed a "hidden address system" to increase the privacy of transactions on the Ethereum blockchain. On his blog, Buterin notes that privacy remains a big challenge for the ecosystem, and that "improving that state of affairs is an important issue."

The blind address system is based on a mechanism that allows any Ethereum wallet to generate cryptographically masked public addresses, called "hidden addresses", to receive funds privately and access them using a special code called a "spend key". Buterin also suggested using ZK-SNARK, shorthand for zero-knowledge proofs, to increase the system's privacy and make it harder to bind hidden addresses.
