David Schwartz, former CTO of Ripple, has provided insights into the recent spikes in XRP transaction fees during periods of high network activity. As XRPL transactions approached 200 per ledger, a level rarely seen, Schwartz explained that fees rise when transaction demand exceeds network capacity. This increase is managed by validators who collectively determine the clearing rate, requiring majority agreement to adjust the fee structure. Schwartz highlighted that even a slight excess in transaction requests beyond the network's capacity can significantly elevate fees. On March 23, XRPL recorded 190 transactions per ledger, marking a one-year high and resulting in fees surging above 1,400 XRP. Validators play a crucial role in maintaining network stability by adjusting transaction targets and fee curves to manage load and prevent system overload.
