Upgrading EVM Application Security w/ Bobafetador (Drosera)
Drosera just shipped to Ethereum mainnet after two years of grinding weekends, audits, and architecture debates—and in this episode we unpack what they’ve actually built and why it matters. Boba, co-founder of Drosera, joins Rex to explain how “traps” let smart contracts watch on-chain conditions and automatically react, turning Ethereum into a far more expressive, always-on system without bolting everything onto a centralized backend. They dig into Drosera’s “L1.5 bandwidth layer” design, how shadow forks and ZK proofs make continuous off-chain execution verifiable on Ethereum, and why decentralization isn’t just about more nodes—it’s about who can realistically run them. The conversation closes with a candid post-mortem on restaking: what the original vision got right, how the incentives went sideways, and why ZK plus lean, grassroots communities may be a healthier path forward than hype-driven “crypto-economic security.”
