Spurious Dragon

Parameters ​

  • 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.
