The developers of the Tezos blockchain have announced "Tezos X," a series of technological upgrades that could significantly improve performance, composability, and interoperability. The roadmap outlines a two-year development plan that includes separating transaction execution into a separate "canonical rollup" that can support atomic transactions across smart contracts written in different programming languages. The main Tezos blockchain will serve as a base layer for consensus and settlement. The new roadmap is similar to Ethereum's scaling efforts, but Tezos' plan involves a single rollup to handle transaction execution instead of multiple layer-2 networks. The canonical rollup is expected to be launched in 2026.
