Bitcoin Community Debates BIP-177 Unit Redefinition

John Carvalho, CEO of Synonym, has introduced Bitcoin Improvement Proposal 177, which seeks to redefine Bitcoin’s base unit to “bitcoin.” The proposal, supported by industry leaders like Jack Dorsey, emerged on April 23, 2025.

BIP-177 is significant as it focuses on simplifying Bitcoin’s usability, aiming to make the cryptocurrency more accessible to newcomers by changing unit denominations.

Bitcoin’s base unit may soon shift from “satoshi” to “bitcoin,” under proposal BIP-177 introduced by Carvalho. Supported by key industry figures, the initiative aims to enhance Bitcoin’s usability without altering its supply, as per financial expert insights.

The proposal intends to redefine Bitcoin’s base unit from satoshis to “bitcoins,” with John Carvalho, CEO of Synonym, leading the initiative. Major industry figures like Jack Dorsey back the idea. The change preserves the current BTC format, potentially easing user engagement.

BIP-177 aims to simplify Bitcoin for users, challenging the standard division into satoshis. The community is divided, with supporters believing it could make Bitcoin more approachable. However, opponents fear it could disrupt current user habits and systems.

Former proposals failed to change Bitcoin’s structure, including Jimmy Song’s 2017 concept of “bits” as a unit. Opponents highlight potential complications in adjusting existing systems. Nonetheless, Satoshi Nakamoto’s openness to modification, according to a 2010 forum post, provides historical precedence.

Jack Dorsey and other influential leaders express support on social media, noting its possible role in advancing Bitcoin’s mainstream adoption. The discourse draws upon broader usability concerns, emphasizing the need for a less complex denomination system, especially for new users.

Reconfiguring Bitcoin’s base unit could alter how users interact with the currency, potentially improving its mainstream appeal. Meanwhile, financial analysts assess implementation challenges, examining historical trends of similar proposals and the potential impact on trading practices.

“Shifting from sats to bits does more than a technical change, it’s a usability upgrade.” – John Carvalho, CEO, Synonym
