Ethereum (ETH) founder Vitalik Buterin proposed 'Keyed Nonces,' a new concept aimed at improving Ethereum's scalability and privacy. He explained via Farcaster, "By utilizing separate storage structures tailored for specific uses, we can reduce network burden while maintaining decentralization. He particularly emphasized that this can efficiently handle the large-scale data problems arising from privacy transactions. Through this, Ethereum will be able to effectively achieve a balance between scalability and decentralization."
