BIP (Bitcoin Improvement Proposal)
BIP is an acronym for Bitcoin Improvement Proposal. A Bitcoin Improvement Proposal is a document including technical specifications on how to improve the Bitcoin protocol. The author of the document presents it to the Bitcoin community as a proposal. Improvements could be essentially anything, typically new environments, features or processes. Proposed changes are a BIP, and the person behind the BIP is also responsible for collecting and documenting both positive and negative input from the community.
