This guide explains BIP 177 Redefine Bitcoin's Base Unit in plain English. It covers the problem behind the BIP, why it matters and whether the proposal is part of Bitcoin today.
TL;DR
- What it is: BIP 177 is a Draft informational proposal to call Bitcoin’s indivisible ledger unit one bitcoin while leaving the BTC currency code at 100,000,000 base units. Under the proposed display convention, a legacy 0.00010000 bitcoin becomes 10,000 bitcoins while remaining 0.00010000 BTC.
- Why it matters: BIP 177 proposes a display-language change, not new monetary rules. Any experiment should preserve exact values, keep BTC unambiguous and use dual labelling until every human and machine boundary has been tested.
- Current position: BIP 177 is a Draft informational proposal to call Bitcoin’s indivisible ledger unit one bitcoin while leaving the BTC currency code at 100,000,000 base units.
BIP 177 Redefine Bitcoin's Base Unit in simple English
BIP 177 Redefine Bitcoin's Base Unit: The proposal assigns the word bitcoin to one base unit while BTC retains its established value of 100 million base units.
Simple example
A node operator is checking BIP 177 Redefine Bitcoin's Base Unit. To convert a legacy bitcoin display into the proposed integer display, multiply by 100,000,000 using exact decimal arithmetic.
Key terms in plain English
- BIP:
- Bitcoin Improvement Proposal: a document describing a proposed rule, standard or process. Its status must be checked separately.
- Consensus:
- The shared rules full nodes use to decide whether blocks and transactions are valid.
- Node:
- A computer running Bitcoin software that checks data and communicates with other peers.
Status and authority
BIP 177 is Draft and Informational. It cannot redefine consensus amounts, force ecosystem terminology or alter balances.
Two meanings
The proposal assigns the word bitcoin to one base unit while BTC retains its established value of 100 million base units. Interfaces must never leave the unit implicit.
Conversion
To convert a legacy bitcoin display into the proposed integer display, multiply by 100,000,000 using exact decimal arithmetic. Reverse conversion divides only at presentation.
Supply
The ledger and total supply are unchanged. A larger displayed integer count is redenomination, not issuance, inflation or a protocol fork.
Transition
The BIP recommends optional toggles, dual displays and explanatory prompts. Payment review screens should show both unit label and exact equivalent during migration.
Compatibility
APIs, invoices, exports and databases using bitcoin as a label may become ambiguous. Prefer explicit BTC or satoshi-unit schemas and version every external contract.
How specialists test it
Developers test the proposal with made-up data on an isolated test network. They check normal cases and deliberately invalid cases. Different implementations should reach the same result before anyone relies on the proposal.
