Summary

Developers in the Tezos ecosystem have introduced the TzEL private blockchain payments testnet prototype, aiming to improve resilience against future quantum computing attacks. The project uses post-quantum cryptography and zk-STARKs (zero-knowledge scalable proofs), while Tezos data availability helps manage proof sizes of about 300KB. The prototype is currently running on the Tezos testnet and is still under development, showing an early-stage effort to explore quantum-resistant payment infrastructure on blockchain networks.

Terms & Concepts
  • Post-quantum cryptography: Cryptographic methods designed to remain secure even if quantum computers become capable of breaking many current encryption systems.
  • zk-STARKs: Zero-knowledge proofs that let a system verify information efficiently without revealing the underlying data, often used to improve privacy and scalability.
  • Data availability: A blockchain design feature that ensures transaction or proof data can be accessed and verified by network participants when needed.
