example:
https://blockchain.info/block/000000000000000000305204772044cd219ca2ed4323c4a541d48924a1a5a03d
BC.I shows Unknown.
the coinbase transaction shows it was mined by "ckpool"
https://blockchain.info/tx/f2b7d7f6c0dea618cfb9774fad5f93dc8d64bb18a5043a9dd19bf758f2c43665?show_adv=true
look at that second output which BC.I shows as "Unable to decode output address" in red, that is an OP_Return output which contains some text which you can see at the bottom.
But my question is why?
for this long and for this many transaction why blockchain info cannot figure out things .
Why they are not fixing the bug?
