Starknet is considering transitioning to L1, with the fastest quantum security upgrade expected in 2027

Eli Ben-Sasson, co-founder and CEO of StarkWare, stated that Starknet, as an L2 relying on Ethereum's underlying security, is considering various options, including transitioning to L1, in order to independently control the network security migration process and address the cryptographic risks posed by quantum computing and AI.

Starknet is built on ZK-STARK, possesses cryptographic agility, and has developed a post-quantum security migration roadmap. Ethereum plans to achieve full resistance to quantum attacks at L1 by the end of 2029, while Bitcoin has not made a similar commitment. Starknet expects to implement related upgrades as early as 2027.
