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.
Due to the shortage of nodes running the updated software as this hard fork approaches, the Ethereum community has called for operators of nodes to update their clients, to avoid consensus issues. As an excerpt from a blog post from the Ethereum Foundation notes:
If you are using an Ethereum client that is not updated to the latest version (listed above), your client will sync to the pre-fork blockchain once the upgrade occurs. You will be stuck on an incompatible chain following the old rules and you will be unable to send ether or operate on the post-upgrade network. Read More...
