zero-knowledge scaling company StarkWare has released a Starknet quantum resistance roadmap, stating that the roadmap is divided into three phases to address the risk of future quantum computing attacks. StarkWare CEO Eli Ben-Sasson stated that Starknet can leverage its architectural advantages to achieve quantum resistance, as its underlying cryptography is based on zero-knowledge STARK proofs. According to reports, the first phase of the roadmap includes replacing part of the existing secure mathematical mechanism, Pedersen hash, with a quantum-resistant version, and adding quantum-resistant signatures; the second phase focuses on migration tools, upgrading existing smart contracts without requiring developers to manually rebuild applications; the third phase involves dependencies that Starknet cannot solve alone, primarily relying on Ethereum's quantum upgrade roadmap. Circle, Ethereum, Solana, Tezos, and Algorand have all proposed quantum resistance roadmaps. (Cointelegraph)
According to Cointelegraph, Tezos ecosystem developers have launched the quantum-resistant privacy payment prototype TzEL on the testnet. TzEL employs post-quantum cryptography and zk-STARK proofs to defend against “harvest now, decrypt later” attacks, safeguarding transaction data and encrypted payment metadata. The prototype also integrates Tezos’ data availability layer to handle the relatively large size of post-quantum proofs. According to the whitepaper, the quantum-resistant zk-STARK proofs used by TzEL are approximately 300 KB in size. TzEL is currently running on the Tezos testnet, and the Tezos ecosystem’s transition to post-quantum cryptography remains in its early stages.
