BIP-177 (Bitcoin Improvement Proposal 177) is a proposal to improve the Bitcoin protocol, aiming to redefine the display method of Bitcoin units to simplify user experience without changing the core protocol or the total limit of 21 million coins. Here is a brief explanation of its core content and impact:
Core Content
- Redefining the base unit: BIP-177 suggests defining the smallest unit of Bitcoin, "satoshi", as "1 bitcoin", replacing the current default unit of "BTC". Currently, 1 BTC = 100,000,000 satoshis, which will change to 1 satoshi = 1 bitcoin.
- Simplifying user interface: The proposal believes that the current 8 decimal places of BTC (0.00000001 BTC = 1 satoshi) is not user-friendly and can cause confusion. Using integers (in satoshi units) is more intuitive and consistent with the Bitcoin protocol's internal use of integers.
- No protocol changes: BIP-177 only adjusts the display method of wallets and user interfaces (UI), without modifying Bitcoin's consensus rules, block size, 21 million coin limit, or miner fees.
Specific Impacts
- Supply limit change (display level): The total supply of Bitcoin remains 21 million BTC, but when calculated with the new unit, it will be displayed as 21 trillion bitcoin (satoshi).
- Price change (display level): Assuming 1 BTC = $100,000 currently, after switching to the new unit, 1 bitcoin (1 satoshi) ≈ $0.001.
- Advantages:
- Lowering the entry barrier for new users, promoting small payment scenarios (such as daily consumption).
- Eliminating visual obstacles caused by decimal points, enhancing intuitiveness.
- Consistent with the integer calculation logic of the Bitcoin protocol.
- Potential Controversies:
- May shake the consensus of some users about the "21 million coins" limit, causing misunderstandings (although the actual total remains unchanged).
- Wallets and exchanges need to adjust UI, and some users may feel confused by the unit switch.
- Community opposition exists, believing that "satoshi" has become a consensus, and changing the unit may add unnecessary complexity or be used as a marketing gimmick.
Current Status
- As of the May 2025 discussion, BIP-177 is still in the draft stage, with mixed support and opposition in the community. Some people (such as @BitcoinErrorLog) believe it can simplify Bitcoin usage, while others (such as @0xAA_Science) are concerned about potential consensus disruption.
- Recent discussions on X platform are heated, with some users mentioning BIP-177 being used in meme coin narratives (such as the token "BIP"), but this is unrelated to the proposal itself and is merely market hype.
Conclusion
BIP-177 is a low-risk UI improvement proposal aimed at making Bitcoin easier to understand and use, especially in small payment scenarios. However, its widespread adoption depends on community consensus and wallet developer support.
