Prabal Banerjee, co-founder of Avail, joined the Cryptonews Spotlight Podcast to discuss the future of blockchain interoperability, scalability, and the importance of chain abstraction in Web3.

With experience at Polygon and leading data availability solutions, Banerjee is at the forefront of solving blockchain’s fragmentation problem.

The Problem with Blockchain Interoperability

“We want to make interoperability possible so that your parents and my parents don’t even need to know that some interoperability is happening there.”

Despite the rapid evolution of blockchain technology, cross-chain communication remains inefficient and complex. Banerjee believes that Web3 must reach a point where users don’t even need to understand interoperability—it should be seamless, just like the internet today.

Avail’s Mission: Building Horizontally Scalable Blockchains

“There will never be a single blockchain that can scale to the demand of 8 billion people.”

Avail is developing a horizontally scalable blockchain infrastructure, ensuring that multiple chains can operate efficiently while providing users with a unified experience.

Blockchain Must Scale Like the Internet

“When I interact with Instagram, I don’t care which server I’m using—it just works. That’s the experience we want to enable in blockchain.”

For Web3 to succeed, blockchains must scale the same way Web2 infrastructure does, providing frictionless access to applications without the complexity of managing multiple networks.

Why Data Availability (DA) is Key to Scaling Web3

“We’re not just building a big server for storing data. We’re building infrastructure that ensures users can verify data availability without relying on a centralized source.”

Avail’s Data Availability (DA) solution allows blockchains to efficiently store and verify transaction data, ensuring a more decentralized and scalable infrastructure.

Avail Nexus: Enabling Trust-Minimized Cross-Chain Communication

“We want users to verify transactions across multiple chains without having to trust an RPC provider.”

Avail Nexus is a new approach to cross-chain communication that uses ZK proofs, TEEs, and fraud proofs to ensure security without relying on centralized intermediaries.

How Avail Fusion Strengthens Blockchain Security

“We are all using blockchains for security. Avail Fusion ensures that rollups inherit the highest level of security possible.”

Avail Fusion is designed to enhance security across rollup-centric ecosystems, ensuring that all chains benefit from strong cryptographic guarantees.

The Current State of Cross-Chain Bridges

“Bridges have been the most vulnerable piece of crypto infrastructure. Fixing interoperability requires solving these deep security challenges.”

Many high-profile hacks in crypto have targeted bridges, highlighting the need for a more secure and efficient interoperability model.

Are We Ready for Mass Adoption?

“If all you need is stablecoins and token transfers, yes, blockchains are ready. But for the seamless experience we envision, we still have work to do.”

Banerjee argues that while blockchain is ready for basic financial applications, it still lacks the scalability and usability needed for true mass adoption.

The Need for More Focus on User Experience

“Most blockchain developers focus on backend infrastructure, but the real problem is making things easy for users.”

Avail is prioritizing light clients and user-friendly experiences, ensuring that users don’t have to deal with technical complexity to access blockchain applications.

Web3 Must Move Beyond Meme Coins and Speculation

“We can’t keep pretending that meme coins and speculation define Web3. We need real use cases and better technology.”

Banerjee emphasizes that Web3 must evolve beyond speculative trading and focus on building real-world applications that drive meaningful adoption.

How Avail is Supporting the Developer Ecosystem

“We are investing in developers, funding hackathons, and providing the infrastructure they need to build the next generation of Web3 applications.”

Avail is actively supporting developers through grants and infrastructure investments, ensuring that the Web3 ecosystem continues to grow and innovate.

What’s Next for Avail?

“We have major launches coming, including one of the biggest social-fi rollups and a new whitepaper for Avail Fusion.”

Avail is preparing for multiple rollup launches, new integrations, and continued research into blockchain interoperability and security.
