263: From Police Officer to Web3 Builder — Rong Kai’s Journey with Reactive Network

Web3 with Sam Kamani

What if smart contracts could see and react to events across multiple blockchains—automatically?

In this episode, I speak with Rong Kai, co-founder of Reactive Network, a groundbreaking Layer 0.5 protocol designed to enable reactive smart contracts that operate fully on-chain.

If you're a developer, founder, or anyone interested in the future of composable, automated smart contracts, this episode is for you.
