The head of the team of developers of the Ethereum Foundation Peter Silage confirmed that the upcoming hard fork Istanbul will take place on 4 December.
November 7, in his blog, Silagi reported that the network upgrade will occur upon reaching 9069000 unit. He has provided operators gcd, using client Geth, a link to the service (maintenance) release, created for the beginning of the initialization, the hard-fork.
Recall that the updating of the network of Constantinople took place in February of this year. Istanbul will be the last update before the final transition to Ethereum 2.0, which will be called Berlin.
Rumor has it that the main feature of Berlin will be the transition to a new algorithm called “Programmatic proof-of-work” or ProgPoW, which will significantly weaken the position of miners using ASIC hardware.
