Avail

Avail is a modular blockchain protocol designed to serve as a dedicated data availability layer. Unlike traditional blockchains that handle consensus, execution, and data storage within a single network, Avail focuses exclusively on ensuring that data for other blockchains and decentralized applications (dApps) is reliably stored, retrievable, and verifiable. This modular approach allows other networks to offload their data availability tasks to Avail, enabling them to scale more effectively without being burdened by intensive data management.

Avail’s architecture separates data availability from the consensus and execution layers, making it a key component for scalable blockchain ecosystems. It ensures that data is distributed across the network in a secure and decentralized manner using techniques like erasure coding and data sampling, which guarantee that even if parts of the network are compromised, the data can still be reconstructed and verified.
