Anybody know.much about the block chain. I had a few digibyte disappear , didn't arrive in my wallet and I confirm all address correct and tx is confirmed ..

I found this address in the block the tx was in

DERn1dcJCK7Yixwur6AtVdGve82HA6EZCW

And most transactions from that address have unreadable text in the field and op_return ??
