Key Details About The Istanbul Hard Fork

Péter Szilágyi, the resident team lead at the Ethereum Foundation, has given us something to mark on our calendars: December 4 is the date to look out for the highly anticipated Istanbul hard fork. In a flurry of tweets on November 7, he dropped the news that the transition will kick off at block 9069000. For all you Geth mainnet node operators out there, there’s a shiny new maintenance release in the works, helping you initiate this journey towards a better Ethereum.

Understanding Geth and Parity Clients

If you’re not deep into the Ethereum world, you might be scratching your head over terms like Geth and Parity. Well, think of them as the ‘on’ and ‘off’ switches for Ethereum nodes. Geth is one of the most utilized clients for operating nodes on the Ethereum network, while Parity is the other big player. Expect an update for Parity upon the activation of Istanbul; however, they’re still trying to figure things out on their end.

The Transition to Ethereum 2.0

The Istanbul fork isn’t just another upgrade; it’s a stepping stone towards Ethereum 2.0. Ever since the Constantinople upgrade rolled out in February, we’ve been inching closer to a shiny new Ethereum, dubbed Berlin. Although set for 2020, rumors have surfaced that Berlin’s hallmark feature could be a new proof-of-work algorithm called “ProgPoW.” This algorithm is designed to level the playing field, reducing the ASIC miners’ upper hand — tailored chips that thrive on mining specific cryptocurrencies.

ASIC vs. GPU Mining: The Great Debate

Speaking of ASICs, here’s where things get interesting. These mining hardware devices are built specifically to mine cryptocurrencies efficiently, hence their dominance. Meanwhile, most hobbyist miners are still rolling with good old GPUs that are less suited for the heavy competition when it comes to snagging those precious rewards. It’s a battle of efficiency versus accessibility, and one that’s caused quite a bit of stir among Ethereum’s community.

Backlash from the Aragon Community

Despite progress, the road to Istanbul isn’t without bumps. Earlier this month, members from the Aragon community voiced their displeasure over the shift to ProgPoW, stating it would disrupt roughly 680 smart contracts on their platform. Jorge Izquierdo, CTO of Aragon One, expressed disappointment over the decision, hinting that the concerns weren’t deemed significant enough to halt the upcoming hard fork. He noted, “It’s a hard balance we understand, but from our point of view, it’s unfortunate.”
