Tezos introduced TzEL, an experimental privacy rollup using zk-STARK proofs and post-quantum cryptography on its testnet. TzEL addresses the “harvest now, decrypt later” problem: encrypted data stored today could be decrypted once quantum computing matures. The project uses Tezos' data availability layer and rollup architecture to handle proofs of up to 300KB per transaction.
Technical expansion: The Tallinn protocol upgrade reduced layer-1 block time from 8 to 6 seconds on January 24, 2026. Financial adjustment: The price of the native token XTZ decreased by 28.7% during the quarter, standing at a value of $0.35. RWA growth: The Uranium.io platform recorded a 1.
The Tezos network has rolled out TzEL on its testnet, a quantum-resistant privacy framework built to safeguard blockchain transaction information against emerging quantum computing capabilities.
