BIP (Bitcoin Improvement Proposal)

A Bitcoin Improvement Proposal is a formal design document for changing bitcoin or documenting its conventions. The process began in 2011 when Amir Taaki submitted BIP 1, modeled on the internet's RFC system. Hundreds of BIPs have since been published, though only a fraction have ever been adopted by the network.

How it works

A BIP moves through drafting, community discussion, and reference implementation before it can be considered for activation. Standards-track BIPs alter consensus rules or peer-to-peer behavior, informational BIPs record design guidance, and process BIPs govern the BIP system itself. Landmark examples include BIP 32 hierarchical deterministic wallets, BIP 39 seed phrases, BIP 141 Segregated Witness, and BIPs 340 through 342, which specified Schnorr signatures and Taproot.

Critically, a BIP carries no authority by itself. Adoption requires voluntary uptake by node operators, miners, wallets, and users, which is why contested proposals can take years to activate or fail entirely.

In the gold vs bitcoin debate

Gold needs no governance because its properties are fixed by physics. Bitcoin's properties are fixed by software that humans can propose to change, and the BIP process is the closest thing bitcoin has to a constitutional amendment procedure. Skeptics see governance risk in that fact; supporters point out that the process has preserved the 21 million coin limit through every upgrade since 2009.
