Serialize encodes the block to w using a format that suitable for long-term storage such as a database while respecting the Version field in the block. This function differs from BtcEncode in that BtcEncode encodes the block to the bitcoin wire protocol in order to be sent across the network. The wire encoding can technically differ depending on the protocol version and doesn't even really need to match the format of a stored block at all. As of the time this comment was written, the encoded block is the same in both instances, but there is a distinct difference and separating the two allows the API to be flexible enough to deal with changes.
