In four days’ time, Ethereum, the second-largest blockchain by its cryptocurrency market’s capitalization (the first being Bitcoin), will see what is known as the “Istanbul” hard fork.
The hard fork, which will implement upgrades to the blockchain, is one of the network’s key named upgrades, which take place around once or twice a year.
Unfortunately though, not all participants in the Ethereum network for the upgrade. Quadency, a cryptocurrency trading platform, recently observed that according to cryptocurrency analytics sites, a majority of nodes running the blockchain, some 60%, are not ready to run Istanbul once the network goes live. 62% of Geth client nodes and 58% of Parity client nodes are not ready, to be exact.
