Avail is working with StarkWare to improve data availability for validation-based appchains within the Starknet Layer 2 network.
This data availability solution is integrated into the Starknet app chain developed using Madara, a custom sequencer. These app chains operate as “Layer 3” in the Starknet ecosystem.
Layer 3 will be able to leverage Avail for data availability in multiple modes, according to the statement. These modes include validation and sovereign rollup, each offering unique advantages in terms of transaction processing efficiency and finality.
The infrastructure will be available on the Madara chain following mainnet launch, scheduled for Q1 2024. Developers can now start experimenting with Madara’s data availability interface on testnet.
“Madara is not just a sequencer. This is a revolutionary tool that enables the creation of custom app chains, providing massive cost savings, personalized control, and areas of innovation previously unachievable in blockchain infrastructure,” said Abdelhamid Bakhta, Head of Exploration at Starknet.
Layer 3 extensions
StarkWare’s multi-layer thesis presents the Layer 2 blockchain as a “universal” scalability solution for Ethereum, with Layer 3 providing low-cost customization and experimentation without the need to build directly on top of Ethereum’s Layer 1.
In this context, Avail aims to further optimize the cost and performance of these Layer 3s, ultimately resolving transactions at Layer 2 of Starknet before achieving finality on Ethereum.
Avail was launched in 2020 by Ethereum scalability developer Polygon Labs as a modular blockchain project with a data availability layer designed to scale blockchain networks. Avail was spun off from Polygon in March this year, led by co-founder Anurag Arjun, who left Polygon to acquire Avail. In April, Polygon head of research Prabal Banerjee also left to join Avail as a co-founder.
