In an interview with Cryptonews, Avail co-founder Anurag Arjun discussed the rebranding of Matic to Polygon and the establishment of Avail to support the future of blockchain technology. Arjun emphasized that the future of blockchain lies in rollups, and Avail is developing critical infrastructure for this shift, including the data availability (DA) layer, Avail DA, and the unification layer, Nexus.

Key Points from the Interview:

1. Evolution of Polygon:
- Originally started as Matic Network in 2017, the team faced initial challenges due to limited resources.
- In 2020, Matic was rebranded to Polygon, expanding beyond the Proof-of-Stake (PoS) chain to include more products and strategies, such as ZK rollups.

2. Focus on Rollups:
- Arjun predicts that future blockchains will predominantly be rollups, which are Layer-2 scaling solutions processing transactions off the main blockchain.
- Rollups offer the advantage of leveraging a base layer's security and can be customized beyond Ethereum Virtual Machine (EVM) rollups.

3. Avail's Role:
- Avail aims to solve data availability issues crucial for rollups with its Avail DA component.
- Avail Nexus will serve as a high-level interoperability layer, ensuring seamless communication and transactions between different rollups.

4. Industry Challenges and Solutions:
- Avail DA is the only project implementing data availability sampling with a validity proof-based approach, addressing the industry's need for scalable infrastructure.
- The unification layer, Avail Nexus, aims to mitigate user experience fragmentation by connecting various rollups, facilitating cross-chain transactions without users worrying about underlying infrastructures.

5. Future Developments:
- Arjun highlighted the importance of transitioning to a rollup-centric architecture while maintaining a unified user experience.
- Upcoming developments include launching Avail DA and showcasing Avail Nexus by connecting Polygon zkEVM and zkSync chains.

6. Additional Insights:
- Arjun shared experiences from co-founding Matic Network and the necessity of a unification layer in a rollup-centric future.
- He also discussed the development of Avail and its impact on creating scalable blockchain applications.
