	FORK_BLKNUM: 2,675,000
	CHAIN_ID: 1


  
    
      
      
         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.
