bLIP stands for Bitcoin Lightning Improvement Proposal. A bLIP is a design document providing information to the Lightning community, or describing a new feature for the Lightning Network. The bLIP should provide a concise technical specification of the feature and a rationale for the feature. The bLIP author is responsible for building consensus within the community and documenting dissenting opinions. Importantly, if a feature is intended to become universal or near universal, it must be a BOLT.

People wishing to submit bLIPs (Bitcoin Lightning Improvement Proposals) should first propose their idea to the Lightning development mailing list. After discussion, please open a PR. After copy-editing and acceptance, it will be published here.

For more detail on the process, please read bLIP-0001 and bLIP-0002.
