We do not yet have a naming convention for improvement proposals for BCH. Thus far everything has been attached to a hard fork or is a BIP. It is easy to keep track of ideas and proposals right now because there are so few. Eventually this will become harder.
For organisational purposes, I am proposing that we adopt CasH Improvement Proposal (CHIP) as the convention of naming improvement proposals for BCH.
Current Proposal Details
The current draft of the guidelines for writing a CHIP along with a template can be found here:
I am still looking for feedback/input on what information should be included in a CHIP.
