According to the co-founder of Ethereum, ensuring the future security of the platform requires the implementation of layer-2 scaling, wallet security, and privacy-preserving features.

According to Vitalik Buterin, one of the co-founders of Ethereum, the future success of the Ethereum platform hinges on three significant technical "transitions" that must occur almost concurrently. These transitions involve layer-2 scaling, enhanced wallet security, and the implementation of privacy-preserving features.

In a blog post dated June 9th, Buterin elaborated on the fact that the Ethereum blockchain experiences significant shortcomings in the absence of a robust scaling infrastructure that can ensure affordable transactions.

Buterin pointed out another potential area of vulnerability, which involves smart contract wallets. He stated that the transition to smart contract wallets has introduced certain challenges, particularly concerning the user experience when managing multiple addresses simultaneously.

Buterin elaborated on the concept of wallet security, emphasizing that to fully embrace an on-chain world with zero-knowledge rollups, wallets must also safeguard data alongside crypto assets.

One of Buterin's final three transitions, privacy, will require advancements in identity, reputation, and social recovery systems.

The co-founder of Ethereum proposed the implementation of stealth addresses as a potential solution to address this problem.

Buterin acknowledged that accomplishing all three transitions would be a difficult task due to the significant coordination required among them. He conceded that each of these transitions poses challenges to the traditional "one user — one address" model, which could potentially complicate transaction execution methods.

Buterin emphasized the importance of constructing a robust framework that ultimately enhances the user experience:
