 The new Bitcoin address format defined is for the Pay-to-Witness-Public-Key-Hash (P2WPKH) and Pay-to-Witness-Script-Hash (P2WSH) transaction described in segregated witness soft fork (BIP141). The scriptPubKey is an OP_0 followed by a push of 20-byte-hash (P2WPKH) or 32-byte hash (P2WSH).
 
 The new address is encoded in a way similar to existing address formats:
-  
+
   base58-encode:
     [1-byte address version]
     [1-byte witness program version]
     [0x00]
     [20/32-byte-hash]
     [4-byte checksum]
-  
+
 For P2WPKH address, the address version is 6 (0x06) for a main-network address or 3 (0x03) for a testnet address.
 
 For P2WSH address, the address version is 10 (0x0A) for a main-network address or 40 (0x28) for a testnet address.
