Harmony (ONE), a Blockchain protocol that provides cross-chain bridges to a number of layer-2 protocols, is the most recent attempt to leverage on this trend. ONE's price has risen 120 percent after hitting a low of $0.095 on Aug. 31 to a daily high of $1.21 on Sept. 9. This follows the announcement of a $300 million ecosystem fund targeted at luring 10,000 engineers and project entrepreneurs.
