Bitcoin Cash (BCC) protocol is a hard fork of the Bitcoin protocol with the following features:
- The blocksize limit has been made adjustable, with an increased default of 8MB
- the legacy Bitcoin code had a maximum limit of 1MB of data per block (or about 3 transactions per second) that caused issues with the old Bitcoin network's capacity as the time required to confirm transactions grew too much).
- See Bitcoin Cash's New Features (with some changes)
- Adjustable Blocksize Cap (ABC) in Bitcoin ABC fork
- A new SigHash transaction signature hashing algorithm indicated by the flag SIGHASH_FORKID
- Provides replay protection not valid on the old Bitcoin Legacy network
- Removes SegWit, a code change that might activate on the bitcoin blockchain by the end of August.

As a fork...Bitcoin Cash's transaction history would be the same as bitcoin's – at least up until the point of the split.
Quoting Bitcoin Cash (with some changes):
All Bitcoin holders as of block 478558 (August 1st, 2017 about 13:16 UTC) are also owners of Bitcoin Cash and have the same amount of Bitcoin Cash as they had Bitcoin at that time.
The home page of Bitcoin Cash is https://www.bitcoincash.org
The ticker symbol is BCC/BCH (the most popular tickers), but XBC is used to meet the International Standard for currency codes (ISO 4217).
Some call Bitcoin Cash an altcoin, a term that usually denotes a fork of the software that creates a new cryptocurrency, with its own market. (see Bitcoin Cash: Why It's Forking the Blockchain And What That Means)
BitcoinABC is the first software to implement the Bitcoin Cash protocol, but the goal is to have more implementations (with Bitcoin Unlimited and Bitcoin Classic coming up with compatible implementations).
