A software upgrade for ethereum was delayed at the last minute amid security fears. The hard fork plan was to launch five extra features aimed at improving the performance of the blockchain network and preparing the ground for further upgrades. However, researchers at security start-up Bitfly said one of the five could make the network vulnerable to hacking. The upgrade, called Constantinople, had been postponed once before, in November. Four of the upgrades would improve efficiency and cut costs while the fifth would reduce cryptocurrency miners’ rewards for using their own computers.
