Tezos launches quantum-resistant private payment prototype "TzEL" on the testnet

Abstract generation in progress
ME News Report, May 15 (UTC+8), Tezos ecosystem developers have launched a prototype of a private blockchain payment testnet called TzEL, aimed at defending against future quantum computing attacks. The prototype uses post-quantum cryptography and zk-STARK proofs to protect transaction data and encrypted payment metadata, preventing "collect first, decrypt later" type attacks. TzEL leverages Tezos's data availability layer to handle the larger proof sizes caused by post-quantum cryptography (approximately 300KB), which was previously a major technical barrier to building scalable on-chain quantum-resistant privacy systems. TzEL is currently running on the Tezos testnet and remains in development, with the Tezos ecosystem's transition to quantum-resistant cryptography still in its early stages. (Source: PANews)

Collecting first and then decrypting is indeed a future threat; for now, this is considered a preemptive measure.

zk-STARK does not require trusted setup and is more suitable for long-term quantum-resistant approaches.

Release it early in development, embodying the spirit of the open-source community.

Private chain + quantum resistance, seems more suitable for enterprise-level scenarios?

Data availability layer mitigates proof size; this engineering trade-off is cleverly done.

The Tezos ecosystem finally has an exciting experiment to look forward to; looking forward to the mainnet.

Post-quantum cryptography + zk-STARKs, quite resource-intensive, how is the 300KB proof handled?

Quantum attacks hit the mark precisely, and the name TzEL is pretty cool.
