Privacy-focused Layer 2 network Aztec has established an end-of-2030 deadline to complete its migration to post-quantum cryptography. The roadmap aims to secure private data against future quantum computing threats, with hardened developer libraries scheduled for release in early 2027 to facilitate the transition. The full implementation of post-quantum security measures remains contingent on corresponding upgrades to the Ethereum base layer. This dependency highlights the coordinated effort required between Layer 2 privacy solutions and the underlying blockchain infrastructure to achieve comprehensive quantum resistance.
