In a recent development, Vitalik Buterin, the creator of Ethereum, has expressed his preference for Rollups over Validiums and disconnected chains for the secure retrieval of funds from Layer 1 chains, as per his latest blog post. Buterin classified Ethereum's Layer 1, 2, and 3 chains, noting that the distinction between Layers 2 and 3 is more architectural than security-based.
Buterin singled out Rollups as the most secure option for returning assets issued on Layer 1 due to their on-chain data storage and robust security guarantees. The choice among various Layer 2 technologies is guided by a balance between security and scalability. Alternative options include Validiums that utilize validity proofs like ZK and store data off-chain.
Looking forward, Ethereum's upcoming Dencun upgrade in 2024 will introduce EIP 4844. This upgrade is designed to enhance data availability across different Layer projects, thereby improving their security and usability. This development underscores Ethereum's ongoing commitment to bolstering its platform's security while simultaneously enhancing scalability.
