BIP
۱۴۰۵/۱/۲۶
A BIP (Bitcoin Improvement Proposal) is the standardized process for proposing, discussing, and implementing changes to the Bitcoin protocol. Introduced in 2011, BIPs give developers, miners, and users a transparent way to collaborate on protocol upgrades.
BIP types
- Standards Track — changes to the Bitcoin network protocol, transaction format, or consensus rules (most impactful)
- Informational — design guidelines or general information, not requiring consensus
- Process — changes to Bitcoin development processes, not the protocol itself
BIP lifecycle
- Draft — author submits a proposal with motivation, specification, and rationale
- Proposed — community review and discussion
- Final / Rejected / Withdrawn — outcome of the review
Notable BIPs
| BIP | Name | Impact |
|---|---|---|
| BIP-9 | Version bits | Soft fork activation mechanism |
| BIP-34 | Block v2 | Block height in coinbase |
| BIP-141 | SegWit | Segregated Witness — fixed transaction malleability, increased block capacity |
| BIP-340–342 | Taproot | Schnorr signatures, improved privacy and smart contract efficiency |
| BIP-39 | Mnemonic seed phrases | 12/24-word wallet backup standard |
BIPs and mining
Miners play a key role in BIP activation. For soft forks, miners signal readiness by setting bits in the block version field. When a threshold (e.g., 90–95% of blocks over a 2-week window) signals support, the upgrade activates. This gives miners direct influence over protocol changes.
