Bitcoin Unit Debate: Sats vs. Bits
Bitcoin Unit Debate Reignites
A recent proposal to alter Bitcoin's base unit to improve user experience has ignited a debate within the Bitcoin community. Bitcoin Improvement Proposal (BIP) 177, introduced by developer John Carvalho, seeks to eliminate satoshis (sats) — the smallest unit of Bitcoin (1 BTC = 100,000,000 sats) — and effectively increase the total Bitcoin supply to 21 quadrillion units. This is despite the underlying Bitcoin economic model remaining intact.
The proposal has faced pushback. Critics argue that satoshis are no more confusing than cents in a dollar. This mirrors a similar debate in 2017, when developer Jimmy Song suggested the use of "bits" (1 bit = 0.000001 BTC). Carvalho counters that bits merely shift the complexity rather than removing it.
Prominent Voices on Both Sides
Support for a unit change includes notable figures like Block Inc. CEO Jack Dorsey, who advocates for simplifying Bitcoin's representation for new users. He believes that using "bits" or eliminating fractional units altogether would be more user-friendly. This sentiment is echoed by Stevie Lee from Spiral, who highlights the unfamiliarity many users have with satoshis.
However, opposition is strong. Swan Bitcoin CEO Cory Klippsten and Byte Federal's Michelle Weekley contend that the familiarity of the satoshi/cent analogy eliminates the need for change. Magdalena Gronowska raises concerns about market perception, suggesting a unit change could be misinterpreted as a significant Bitcoin price crash or inflation.
Satoshi Nakamoto's Stance
Interestingly, even Bitcoin's creator, Satoshi Nakamoto, showed openness to adjusting Bitcoin's unit display for usability in a 2010 forum post. Nakamoto suggested altering the decimal point placement to simplify handling small transactions.
