The public key was lost in this chapter when dissecting the transaction in whole. For completeness, a table demonstrating a breakdown of the ScriptSig was necessary to cover this.
* The length of the +scriptSig+ is 139 bytes, or +8b+ in hex
* The sequence number is set to +FFFFFFFF+, again easy to identify((("", startref="alicesix")))
When scriptSigs are serialized for transmission on the network, their inputs are encoded into a byte stream as shown in <<ScriptSig input serialization>>.
