This week on The Defiant Podcast we speak with A.J. Warner, the Chief Strategy Officer at Offchain Labs, the builders of Arbitrum, one of the leading scaling solutions for Ethereum using Optimistic Rollups. We also welcome Tegan Kline, the co-founder of Edge Node, the initial team behind The Graph.

The Defiant’s Camila Russo and Tegan are co-hosting the podcast for the first time. Going forward, they will record shows together, and Tegan will also have her own Defiant podcast episodes.

Scaling is now a hot topic on Ethereum and throughout the blockchain ecosystem, as all of our listeners are likely aware. According to L2Beat, Arbitrum has nearly $2.7B in total value locked. AJ goes on to explain the dapps and protocols building on Arbitrum and how they’ve managed to make Arbitrum the leading destination among Layer 2s.

Arbitrum is one of the few scaling solutions that doesn't nod to the underlying technology it uses in its name. As AJ mentioned, their goal is to scale Ethereum without being a proponent of any scaling technology. Does this mean Arbitrum will have a zero-knowledge (ZK) component in the future?
