Berlin And London Hard Forks: A Short Summary

What changes did the Berlin hard fork bring?

  • Reduced the gas costs for some transactions,
  • Increased the gas costs for the so-called “op code” transactions that hindered the denial of service attacks on Ethereum,
  • Made all transactions “backwards compatible” using so-called “envelope transactions”. This allowed users to make templates for combined transactions with lowered gas prices.
