 A <code>witness root hash</code> is calculated with all those <code>wtxid</code> as leaves, in a way similar to the <code>hashMerkleRoot</code> in the block header.
 
 The commitment is recorded in a <code>scriptPubKey</code> of the coinbase transaction. It must be at least 38 bytes, with the first 6-byte of <code>0x6a24aa21a9ed</code>, that is:
-  
+
    1-byte - OP_RETURN (0x6a)
    1-byte - Push the following 36 bytes (0x24)
    4-byte - Commitment header (0xaa21a9ed)
   32-byte - Commitment hash: Double-SHA256(witness root hash|witness reserved value)
-  
+
   39th byte onwards: Optional data with no consensus meaning
-  
+
 and the coinbase's input's witness must consist of a single 32-byte array for the <code>witness reserved value</code>.
 
 If there are more than one <code>scriptPubKey</code> matching the pattern, the one with highest output index is assumed to be the commitment.
