After a failed testing of Constantinople, the second part of the Ethereum hardfork, developer team decided to delay its launch until the start of next year. It is possible that the update could ship with an implemented ProgPow algorithm.

During a video conference call Ethereum’s next stage developers concluded that its launch, planned earlier for next month, should be postponed, considering that on October 13th during the test launch of Constantinople in Ethereum’s testnet, Ropsten hardfork showed several mistakes.

When Constantinople launches, hardfork will add five irreversible changes to the network, after which previous versions of the software will become incompatible with it. This includes both minor improvements like code optimization and major changes like decreasing block rewards.

Launch delay could also be used for implementation of ProgPow Consensus algorithm into the hardfork, which will increase the network’s resilience to industrial mining equipment and decrease its centralization. Previously, the team planned to integrate ProgPow into the network with another hardfork (after Constantinople launch), which should have eased the transition to a new algorithm from traditional PoW. Ethereum Foundation’s Chief of Security, Martin Holst Swende, said:


“If Constantinople won’t be launched until January or February of next year, then I will probably try to include ProgPow right into it.”


Constantinople hardfork is part of Ethereum’s update, which is viewed by developers as an important step towards the general improvement of platform’s ease of use. The first stage of Metropolis – Byzantium – was successfully launched in September last year.
