BIP stands for [[Bitcoin]] Improvement Proposal. It's a design document that proposes changes or upgrades to the Bitcoin network. Anyone can submit a BIP, which then undergoes a review process by Bitcoin developers and the community. BIPs can propose changes to the Bitcoin protocol, like new features or security enhancements, or they can be informational, providing general guidelines or clarifications. They are a key mechanism for the evolution and maintenance of the Bitcoin network, ensuring transparency and collaboration in its development.
