Bitcoin’s Smallest Unit, the Satoshi, Is Suddenly on the Defensive

The smallest named unit of Bitcoin (BTC), the satoshi, is suddenly being defended after Block Inc. chief executive Jack Dorsey publicly endorsed scrapping it in favour of calling every indivisible integer of the network simply “bitcoin.”

On Sunday the former Twitter CEO reposted a remark by “grubles” and added his own assessment: "sats are so confusing to people just getting into bitcoin. bits of bitcoin is better, and just bitcoin is best."

Dorsey's interjection came in response to grubles who argued that “‘Sats’ are technically bitcoin. So it's not incorrect to just stop calling them sats and just call them bitcoin again.” One critic replied that the discussion showed that “people have nothing else to worry about,” to which Dorsey shot back: “I'm very worried about Bitcoin becoming money. It must.”

The immediate backdrop is improvement proposal 177 (BIP 177), introduced on 23 April by Synonym CEO and developer John Carvalho. The document would “redefine the commonly recognized ‘bitcoin’ unit so that the base unit becomes the primary reference unit,” eliminating the customary eight-decimal presentation and deprecating the term “satoshi.” Internally nothing changes; what users now know as 1 BTC would display as 100 000 000 bitcoins, while wallets could offer a legacy toggle for backwards compatibility.

Imposing an integer-only view cleans up education and user interfaces by exposing the protocol's true nature, Carvalho argues: "Bitcoin's ledger represents values as integral base units. The decimal point is merely a human-imposed abstraction." Supporters say that ditching decimals removes the psychological hurdle that drives newcomers to cheaper-looking altcoins and that the move is like a “stock split” rather than monetary debasement.

But resistance has been fierce. Swan chief executive Cory Klippsten, Byte Federal product director Michelle Weekley and consultant Magdalena Gronowska all warn that multiplying apparent supply from 21 million to 2.1 quadrillion “bitcoins” would sow chaos.

"People understand cents in a dollar, they will understand sats in a Bitcoin," counters Weekley, while Gronowska fears some users "could think that Bitcoin abruptly crashed from its current price of around $100,000 and that its supply has massively inflated."

The currency's pseudonymous inventor anticipated such a shift, notes Robin Linus, creator of the Bitcoin Virtual Machine (BVM). In a 6 February 2010 Bitcointalk post, Satoshi Nakamoto wrote: "If it gets tiresome working with small numbers, we could change where the display shows the decimal point... Same amount of money, just different convention."

The denomination debate is hardly new: Jimmy Song's 2017 BIP 176 proposed "bits" (one-millionth of a BTC) as a friendlier frontage, but Carvalho dismisses that as retaining a "layered decimal approach" and "shifting complexity rather than eliminating it."

No Bitcoin consensus-critical change has been activated since the Taproot soft fork in November 2021, and BIP 177 would likewise require only interface, not protocol, updates—yet a norm change still depends on widespread voluntary adoption by wallets, exchanges and payment processors.

For now the market shows little concern. Bitcoin was trading at about $102,786.
