Hi everyone, I am Suzana Joel from IBC Media. Currently, we’re organizing Genesis DevCon - a blockchain developer conference on 24th & 25th of November at IISc in Bengaluru. The objective of genesis

I understand your point. In the case of the auction system, nevertheless, how can I get the best current price when I do transaction queries. Maybe I have to use the range-based queries to seek the
