A Bitcoin Improvement Proposal (BIP) is a proposal for a change or an improvement to the Bitcoin network. It is a way for anyone who has an idea for how to improve Bitcoin to submit their proposal to the community for discussion and review. BIPs are typically submitted by Bitcoin developers, but anyone can submit a proposal. The process of reviewing and implementing BIPs is designed to be open and transparent, and it is overseen by a group of volunteers known as the Bitcoin Improvement Proposals Working Group (BIPs WG). BIPs can cover a wide range of topics, including changes to the Bitcoin protocol, new features for the software, and improvements to the user experience.
