The Bitcoin market reacted positively, climbing 4% on May 19, 2025, to briefly reach $107,000, indicating a growing interest in the proposal.

BIP-177 proposes renaming Bitcoin's smallest unit from 'satoshis' to 'one bitcoin' to reduce confusion for users and enhance mainstream adoption.

Jack Dorsey, the founder of Twitter, supports this proposal, arguing that the term 'sats' hinders Bitcoin's acceptance as a currency.

Carvalho's proposal would effectively increase Bitcoin's total supply from 21 million to 21 quadrillion units, simplifying user interactions.

Implementing BIP-177 would not require major technological upgrades, but developers will need to update user interfaces, APIs, and documentation.

Under the new system, a value of 0.0001 BTC would be expressed as 10,000, making it easier for users to understand and calculate transactions.

Opponents, including Swan Bitcoin CEO Cory Klippsten, argue that users can understand satoshis just as they understand cents in a dollar.

The core Bitcoin protocol remains unchanged; the focus is on how Bitcoin values are communicated to users.

The last significant change to Bitcoin's protocol was the Taproot soft fork in November 2021, and BIP-177 similarly relies on adoption by wallets and exchanges.

BIP-177 aims to address misconceptions about Bitcoin's structure, as many users mistakenly view it as a decimal-based currency.

The proposal is designed to simplify user interactions with Bitcoin, reducing errors in calculations and making it more accessible for beginners.

Since its introduction by John Carvalho in May 2025, BIP-177 has garnered support from key figures in the crypto community, including Dorsey.
