We need our own node for transaction checking purposes, fore block explorer API has their limits on number of request after which their block ip from which the requests are made...And i thought to my self if you set up your own node you will be limited only to a speed of CPU and internet speed of the machine on which node is set up...Dedicated server definitely. May be anybody familiar with the limit situation? Or how to avoid it? Or any paid block explorer API services))? Once again we don't need to post no transactions just for checking purposes. Thanks to everybody. Happy holidays
