EIP: 160
Title: EXP cost increase
Author: Vitalik Buterin
Type: Standard Track
Category: Core
Status: Final
Created: 2016-10-20
```

### Specification

If `block.number >= FORK_BLKNUM`, increase the gas cost of EXP from 10 + 10 per byte in the exponent to 10 + 50 per byte in the exponent.

### Rationale

Benchmarks suggest that EXP is currently underpriced by a factor of about 4-8.
