As you can see, a Segregated Witness output’s locking script is much simpler than a traditional output. It consists of two values that are pushed on to the script evaluation stack. To an old (nonsegwit-aware) bitcoin client, the two pushes would look like an output that anyone can spend and does not require a signature (or rather, can be spent with an empty signature). To a newer, segwit-aware client, the first number (0) is interpreted as a version number (the _witness version_) and the second part (20 bytes) is the equivalent of a locking script known as a _witness program_. The 20-byte witness program is simply the hash of the public key, as in a P2PKH script

Now, let’s look at the corresponding transaction that Bob uses to spend this output. For the original script (nonsegwit), Bob’s transaction would have to include a signature within the transaction input:
