What is Avail (AVAIL)?

TLDR Avail (AVAIL) is a modular blockchain base layer solving data availability and interoperability challenges to unify fragmented ecosystems.

1. Core infrastructure – Provides scalable data availability (DA) for rollups and cross-chain transactions
2. Interoperability focus – Enables seamless asset transfers across chains via Nexus unification layer
3. Security-first design – Combines validator decentralization with Fusion's multi-asset crypto-economic security

Deep Dive

1. Modular Foundation

Avail operates as a data availability layer - critical infrastructure ensuring transaction data remains accessible for verification. Using KZG polynomial commitments and erasure coding, it allows rollups to scale while maintaining Ethereum-level security. This solves the bottleneck where 80-90% of rollup costs previously went to Ethereum DA (Avail blog).

2. Cross-Chain Unification

The Nexus layer acts as a universal router, connecting ecosystems like Ethereum, Polygon, and Arbitrum without bridges. Developers integrate once via SDKs to access native liquidity across 11+ chains – users can transact cross-chain without leaving their wallet (X post).

3. Security Architecture

Avail combines:
- 1,000+ validators – Byzantine Fault Tolerant consensus resisting collusion
- Fusion Security – Staked BTC/ETH supplements network security, creating attack-resistant crypto-economic mesh
- Light clients – Enable trust-minimized verification on mobile devices

Conclusion

Avail positions itself as essential plumbing for Web3 – a decentralized base layer enabling scalable dApps and frictionless cross-chain interactions through modular design. With partnerships spanning AI chains (Heurist), RWA platforms (Lumia), and data networks (Space & Time), its success hinges on whether developers prioritize interoperability over chain-specific optimization.
