Tezos launches quantum-resistant private payments prototype TzEL on its testnet
According to ChainCatcher, citing a report from Cointelegraph, developers from the Tezos ecosystem have launched a prototype of a private blockchain payment testnet called TzEL, aimed at resisting future quantum computing attacks.
This prototype uses post-quantum cryptography and zk-STARK proofs to protect transaction data and encrypted payment metadata, preventing "collect now, decrypt later" type attacks. TzEL leverages Tezos's data availability layer to handle the relatively large proof size (about 300 KB) brought by post-quantum cryptography, which has been one of the main technical barriers to building scalable on-chain quantum-resistant privacy systems. TzEL is currently running on the Tezos testnet and remains under development, with the transition of the Tezos ecosystem to quantum-resistant cryptography still at an early stage.
