This represents the simplest and most straightforward scheme. The commitment is inserted into the first OP_RETURN output of the in the following way:

34-byte_Opret_Commitment =
 OP_RETURN   OP_PUSHBYTE_32   <mpc::Commitment>
|_________| |______________| |_________________|
  1-byte       1-byte         32 bytes

mpc::Commitment is the 32-byte Tagged hash resulting from the which is covered in detail . Hence an opret commitment will have a total size of 34 bytes.
