Tezos has activated its 16th protocol upgrade, “Paris,” on mainnet, a milestone in the Tezos X roadmap aimed at dramatically increasing throughput and improving the user and developer experience on both Layer 1 and its EVM-compatible Layer 2, Etherlink. The Paris upgrade introduces a new high‑throughput “data‑availability‑layer‑like” feature and other performance optimizations that Tezos ecosystem contributors say pave the way to handling millions of transactions per second in future rollup architectures while keeping fees low. Following the upgrade, the Etherlink L2 has reportedly become cheaper to use than leading Ethereum L2s such as Arbitrum and Optimism, with lower gas costs and a smoother UX for users and dApp developers. Paris continues Tezos’ long‑running strategy of frequent, self‑amending upgrades through on‑chain governance, building on previous protocol iterations that reduced block times, improved consensus, and optimized storage. The upgrade is part of the broader Tezos X plan to position Tezos as a high‑performance base layer for rollups and modular architectures, with Etherlink serving as its flagship EVM-compatible rollup where Ethereum developers can deploy Solidity smart contracts while benefiting from Tezos’ security and lower fees. By making Etherlink more cost‑competitive than major Ethereum L2s and improving UX, the Tezos ecosystem is targeting increased DeFi, gaming, and general‑purpose dApp activity on its stack, seeking to differentiate via performance, formal‑verification‑friendly tooling, and energy‑efficient proof‑of‑stake.
