Welcome to the Avail Project Developer Documentation, your go-to resource for all things related to data availability and modular blockchain development. Designed with a focus on community collaboration, this repository aims to provide the most accurate, comprehensive, and up-to-date information for anyone interested in learning about, contributing to, or maintaining projects within the Avail ecosystem.
Avail provides a secure, trust-minimized base layer designed for high data availability, forming the cornerstone of next-generation, scalable applications. Its core features include:
- Data Blob Indexing: Streamlines data indexing by associating transaction data with specific application IDs.
- Erasure Encoding: Enhances data resilience, making it more challenging for nodes to withhold information.
- KZG Polynomial Commitments: Guarantees data presence in the block header.
- Decentralized Network of Validators: Targets a network of up to 1,000 external validators to minimize centralization risks.
- Validity Proofs: Enables light clients to instantly confirm state correctness and data availability upon finalization.
Leveraging Data Availability Sampling, Avail's light client network ensures robust data availability. With an increasing number of light clients, Avail supports larger blocks, thereby unlocking substantial scaling capabilities for blockchain technologies.
