Team lead at the Ethereum (ETH) Foundation Péter Szilágyi has confirmed Dec. 4 as the expected date for the network’s forthcoming Istanbul hard fork.
In two tweets posted on Nov. 7, Szilágyi indicated that Istanbul will commence at block 9069000. He provided Geth mainnet node operators with a link to a new maintenance release designed to begin the hard fork’s initialization.
Geth is the name given to one of the two most popular clients used to operate nodes on the Ethereum network — the other being Parity, which will update upon the activation of Istanbul but is now in the review stage.
Ethereum gets closer to 2.0
Following the Constantinople upgrade — which was completed in February of this year — Istanbul represents the latest hard fork in the network’s eventual transition to Ethereum 2.0, dubbed Berlin, intended to be Ethereum’s final upgrade which is set to take place in 2020.
Berlin’s most significant feature is rumoured to be the implementation of a new programmatic proof-of-work (PoW) algorithm dubbed “ProgPoW,” which is intended to combat the advantage that ASIC miners have on the network.
“ASIC” refers to mining hardware that uses Application-Specific Integrated Circuit (ASIC) chips, which are tailored to efficiently mine cryptocurrency based on a specific hashing algorithm.
Ethereum’s developers decided to split the implementation of Istanbul into two stages, beginning with a version that included a selection of six Ethereum Improvement Proposals (EIPs) for testnet integration in October.
Aragon DAO platform declare opposition to Istanbul
Earlier this month, community members of Aragon — an open-source software project for creating Ethereum-based decentralized autonomous organizations (DAOs) — proclaimed themselves against the protocol’s shift to ProgPow.
Aragon One CTO Jorge Izquierdo had indicated in late October that Istanbul would result in breaking of roughly 680 smart contracts on the Aragon platform, stating:
“The issue we’re going to have hasn’t been deemed important enough for this hard fork not to happen, which from our point of view is unfortunate [but] it’s a hard balance we understand.”
