Big things coming #

The activation of Oxford 2 is just the beginning of a big 2024 for Tezos. We are excited to be part of the ongoing work to evolve Tezos – and the blockchain space.

Data-Availability Layer (DAL) on testnet. The DAL is currently live on Tezos’ Weeklynet, and we encourage bakers and rollup operators to help us test this cornerstone of Tezos’ future. To understand what it does, and what it means for Tezos, see our introduction to the DAL.

Get ready for the launch of Etherlink. Etherlink will be an EVM-compatible optimistic rollup with high throughput, a decentralized sequencer, low gas fees, and MEV protection, powered by Tezos Smart Rollups. Check out to learn more and get involved.

Meanwhile, we are busy working on an upcoming protocol upgrade proposal, “P”. Stay tuned!
