October 2019 Planned Ethereum Network Upgrade


Afri proposed the following schedule on the Jan 4th All Core Devs call where it was provisionally accepted. That same thread has a lot of push for ProgPoW, an ASIC resistant mining algorithm change. There is ongoing discussion about a pre-Istanbul hardfork to include this.

  • 2019-01-16 (Wed) projected date for mainnet network upgrade (“Constantinople”)
    • Note: updated dates / links re: Constantinople re-schedule need to be included
  • 2019-05-17 (Fri) hard deadline to accept proposals for “Istanbul”
  • 2019-07-19 (Fri) soft deadline for major client implementations
  • 2019-08-14 (Wed) projected date for testnet network upgrade (Ropsten, Görli, or ad-hoc testnet)
  • 2019-10-16 (Wed) projected date for mainnet upgrade (“Istanbul”)
