Ethereum Founder Vitalik Buterin Acknowledges All ETH L2s Have 'Backdoors'

Ethereum ETH/USD founder Vitalik Buterin has acknowledged the presence of what he termed "training wheels" in the current Ethereum Layer 2 (L2) solutions.

These "training wheels" refer to backdoors that allow developers to intervene and modify the protocol in case of bugs or other issues.

Buterin's comments shed light on the ongoing debate about the security and decentralization of L2 solutions on Ethereum.

Layer 2 solutions, commonly known as "roll-ups" or "L2s", have been developed to address the scalability issues of the Ethereum blockchain.

These solutions aim to process transactions off-chain, thereby reducing the load on the main Ethereum chain and speeding up transaction times.

However, the presence of backdoors in these solutions has raised concerns about their security and decentralization.

Buterin stated, "The Rollups and Layer twos that exist on Ethereum today... basically all have what I call training wheels, like some kind of backdoor that lets developers come in and like say, stop and change the protocol if they see that some kind of bug has happened."

While these backdoors are intended to serve as a safety mechanism, allowing developers to intervene in case of issues, they also present potential vulnerabilities.

If exploited, these backdoors could compromise the security of funds or data stored within the L2 solutions.
