Whitepaper

"Bitcoin: A Peer-to-Peer Electronic Cash System" by Satoshi Nakamoto.

Bitcoin Cash is one chain of Satoshi Nakamoto's blockchain invention which was deliberately hard-forked on August 1st, 2017. It shares the whitepaper, first block, and all bitcoin block history prior to the fork. It attempts to implement the central idea outlined in that paper.

Simple Ledger Protocol (SLP Token)

Simple Ledger Tokens (SLP) was an early implementation of tokens as data stored on Bitcoin Cash. Due to issues with both scale, usability and validation, this functionality was migrated to be a first class feature of Bitcoin Cash with new script code.
