KEY TAKEAWAYS
- Tezos has launched its Data Availability Layer (DAL) to enhance rollup scalability, introduced with the Paris protocol upgrade.
- The DAL aims to boost Tezos network bandwidth, offering a 20-fold improvement for layer 2 solutions, with a long-term goal of a 4000-fold increase.
- Security is maintained through layer 1, ensuring that scaling improvements do not compromise network integrity.
- Community involvement is crucial for activating the DAL, requiring 67% of Tezos stake to run DAL nodes.
The Tezos blockchain network has unveiled its Data Availability Layer (DAL), a significant advancement aimed at improving the scalability of rollups. This development was introduced with the Paris protocol upgrade and is a crucial component of the Tezos X roadmap, which aspires to deliver unmatched performance, composability, and interoperability.
The DAL is designed to increase the Tezos network’s bandwidth, which refers to the volume of transaction data that can be published on-chain per second. Currently, this bandwidth is constrained by the capacity of layer 1 blocks. However, the DAL offers an immediate 20-fold enhancement for layer 2 solutions like rollups, with a long-term goal of achieving a 4000-fold improvement, or 100MB/s, within two years.
One of the standout features of the DAL is that it maintains security through layer 1, a characteristic that distinguishes Tezos in the blockchain industry. This feature ensures that while scaling is significantly improved, the security of the network remains uncompromised. More details on the DAL’s security and functionality can be found in Nomadic Labs’ blog post.
The DAL not only addresses a major scaling bottleneck for rollups but also reduces the cost of operating them. For instance, Etherlink, a Smart Rollup-powered Ethereum Virtual Machine (EVM) environment on Tezos, is set to integrate with the DAL, further lowering the already minimal cost of publishing transactions.
To activate the DAL, at least 67% of the Tezos stake is required to run DAL nodes. While bakers, who are responsible for operating these nodes, play a crucial role, the broader Tezos community is encouraged to participate. Community members can support this initiative by reaching out to their bakers and emphasizing the DAL’s importance for scaling and its potential benefits for the ecosystem.
As the Tezos community rallies to activate this rollup booster, the network is poised to take a significant step forward in its journey towards Tezos X, solidifying its position as a blockchain with industry-leading technology.
