Vitalik Buterin, co-founder of Ethereum, said that building layer-2 networks to leverage Ethereum’s core features delivers security and efficiency unachievable by earlier enterprise blockchains. The statement was made on X.
"The best way to build an L2 is to lean into the L1's offerings (security, censorship resistance, proofs, data avail...) more, and reduce your logic to just being a sequencer and a prover (if based, just a prover) over the core execution," said Buterin. "This is the combination of trust minimization and efficiency that the 2010s enterprise blockchain crew wanted, but was never able to achieve. Now, with Ethereum L2s, you can achieve it. And we've already seen successful examples of the L1's features protecting users' rights if something on the L2 goes wrong."
In 2025, alternative Layer-1 (alt-L1) blockchains such as Celo and Gnosis Chain have begun transitioning to Ethereum Layer-2 solutions to benefit from Ethereum’s security and ecosystem. According to The Block, these projects cite lower fees, stronger network effects, and improved interoperability as the main reasons for the move. This reflects a growing industry consensus that Ethereum L2s offer better long-term prospects than competing L1s.
