How to see the number of segwit transactions in a block Now that segwit is active I am interested to know how many segwit transactions are in each block.

The Blockchain explorers I've looked at don't seem to be tracking this info.

Is there any service that would allow me to view the number of segwit transactions which are in each block.
Look here under "Transactions (Segwit)" tab:
