PEEPanEIP-7939: Count Leading Zeros (CLZ) Opcode with Vectorized

PEEPanEIP-7939: Count Leading Zeros (CLZ) Opcode

In PEEPanEIP episode 153, we sat down with Vectorized to explore EIP-7939: Count Leading Zeros (CLZ) Opcode.

This seemingly simple opcode could unlock meaningful improvements in:

• ZK proving performance
• Bytecode size optimization
• Gas efficiency
• Math and compression-heavy operations
• General expressiveness of the EVM

Covered in the episode:

• What is EIP-7939?
• Why CLZ matters for Ethereum
• Use cases and examples
• Gas and safety considerations
• Future implications for ZK and EVM logic

Would love to hear thoughts from developers and protocol folks—how does this opcode help your app?
