How can I check mining result exactly?

Mining

The way I know is to enter the address below on the web page.
https://ctc.coiner.kro.kr/miningBlock.do?account=[Public key]

If the result says “no data” here, no blocks have been mined?

I’d appreciate it if you could let me know if you could check the mining results in any other way.

There is no other way to check, for now.
Yes. you mined no block if there is no data.
