Three Scaling Constraints

Ethereum’s next big leap might not look like a single “flip the switch” moment—but it could change how the chain verifies everything. In this episode, Ansgar Dietrichs comes back to unpack the ZK EVM: why “re-executing every block” has been Ethereum’s hidden scaling tax, how real-time proofs finally make a different verification model viable, and what it would take to transition safely without sacrificing the verifiability that keeps Ethereum credibly neutral. They explore the three true bottlenecks of blockchain scaling (compute, IO, bandwidth), the roadmap from optional proofs to mandatory proofs, and why client diversity could look radically different in a ZK-native future.
