Starknet Tackles Quantum Threat by Targeting Independence

Background

Starknet is considering becoming a standalone Layer 1 blockchain to achieve quantum resistance by 2027.\\ This move would give Starknet more control over its security upgrades and target the growing threat of quantum attacks.\\ The proposed timeline puts Starknet ahead of Ethereum, which is targeting full Layer 1 quantum resistance by the end of 2029.\\ \\ \\ \\

Key Considerations

Starknet already uses zero-knowledge STARK proofs based on hash-based cryptography and has an active roadmap for post-quantum security.\\ However, as a Layer 2 on Ethereum, the network still relies on its parent chain for some of its security.\\ Two areas are still outside the direct control of its builders, including bridge messaging and data availability.\\ \\ \\ \\

Proposed Timeline

Starknet has announced that it is actively considering becoming an L1, describing the change as a route toward becoming the first fully quantum-resistant network.\\ The proposed timeline of 2027 puts Starknet ahead of Ethereum, provided it can complete the remaining work and settle the architectural questions involved in becoming an independent chain.\\ \\ \\ \\

Challenges Ahead

An independent Starknet would still need to resolve data availability, final settlement, and changes to its official bridge.\\ The bridge question carries particular weight, especially considering that today, Ethereum verifies Starknet withdrawal proofs before bridged funds can be released.\\ If Starknet becomes an L1, it could continue posting STARK proofs to Ethereum, preserving a connection between the networks, or sever that dependency entirely.\\ However, those approaches would create different security assumptions for users.
