Thanks @0ceanSlim for your proposal. I don’t think I saw discussion about this on the mailing list, did you post it there? This looks fairly complete already, I just have a few formatting suggestions. Note that the “Created” header in the preamble refers to the date that a proposal was assigned a number, so the current value should be “?”.

murchandamus commented at 10:09 pm on April 28, 2025:

I meant that the two paragraphs currently don’t contain full sentences as they don’t have punctuation, but also aren’t formatted as lists, so I was thinking that either each section should be a paragraph with multiple sentences or each section should be a list. Either way, the summarizing sentence should probably not belong to the subsection about BIP 177 but precede both:

1
2==== BIP-176: Bits Denomination ====
3BIP-176 proposes using "bits" as a standard term for 100 satoshis (or 0.000001 BTC). While this proposal has merit for creating a middle-ground denomination that avoids small decimal places when bitcoin's value is high, our approach differs in that it: Formalizes existing widely adopted terminology rather than introducing or prioritizing a different unit, focuses on the fundamental base unit that cannot be subdivided further within the Bitcoin protocol, and maintains the simplicity of a two-tier system (bitcoin and satoshi) rather than adding a third tier.
4
5==== BIP-177: Redefine Bitcoin's Base Unit ====
6BIP-177 takes a more radical approach by proposing to redefine the term "bitcoin" to refer to what is currently called a "satoshi" (1/100,000,000 of the current bitcoin). While this proposal aims to eliminate decimal points and simplify mental calculations, our approach differs in that it:
7
8Preserves the established meaning of "bitcoin" which has global recognition and avoids potentially confusing redefinition, maintains compatibility with existing systems, documentation, and user understanding, and achieves similar clarity benefits through standardization without requiring a fundamental redefinition of terms.

45+
46+The term "satoshi" and its abbreviation "sats" have already gained widespread adoption within the Bitcoin community. This BIP seeks to formalize this existing convention rather than introduce new terminology.
47+
48+=== Analogous to Traditional Currency Systems ===
49+The proposed bitcoin/satoshi (or BTC/sat) standard follows the established pattern of major world currencies, which typically have a primary unit and a smaller subunit. Most notably, the United States dollar—the world's primary reserve currency—uses dollars and cents in a two-tier denomination system. This familiar dollars/cents model has proven effective and intuitive for everyday transactions across different scales.
50+The bitcoin/satoshi system mirrors this approach while accounting for Bitcoin's higher divisibility requirements. Furthermore, the phonetic similarity between "sat" and "cent" creates an intuitive bridge for newcomers to understand Bitcoin's smallest unit, making the learning curve less steep for those familiar with traditional currency systems. This natural familiarity aids adoption by leveraging existing mental models of how currency denominations work.

edilmedeiros commented at 6:43 pm on April 29, 2025:

I appreciate the observation that “sat” sounds like “cent” (I’m too stupid to have realized it myself), but saying that this phonetic familiarity improves adoption is quite a big step for me. Just having a standard way to talk about small quantities without resorting to long decimals seems to be all the justification required for the proposal.

0ceanSlim commented at 7:06 pm on April 29, 2025:

Maybe it doesn’t “improve adoption”. You’re right in that. But the phonetic similarity does help with out mental model of todays currencies, which was more my point. Do you have a suggestion as to a better way to word this that works for everyone?

As for the symbol, I briefly considered adding a section on a symbol. satsymbol.com has a symbol for sats that’s been widely adopted by many apps. This is what I would have proposed be the symbol for sats. But I felt it was outside the scope of this BIP. Perhaps a BIP in the future to define symbols can come. There is nothing that says an orange B with lines through it tilted to the right is the official symbol for Bitcoin either. Bitcoin has no official symbol. This and being outside the scope of this BIP was why I left it out for now. I think symbols could use it’s own BIP to formally define Bitcoin and satoshis alike.

0ceanSlim commented at 2:46 pm on April 30, 2025:

I changed the wording to not suggest this aid adoption.

edilmedeiros commented at 6:56 pm on April 29, 2025: none

Maybe this will be out of scope for this proposal, but feels so related that I can’t not mention it.

Unicode has standardised a Bitcoin symbol under code U+20BF: ₿

Plane 0: Basic Multilingual Plane Unicode Block: Currency Symbols Unicode Version: 16.0

Would be at least nice to have it mentioned since you are formally defining 1 bitcoin in term of satoshis.

Unfortunately, they didn’t define a symbol for satoshis. Maybe this proposal helps to justify doing so in the future, even though I believe we don’t have such a common currency symbol for satoshis.

murchandamus commented at 8:42 pm on April 29, 2025: contributor

Maybe this proposal helps to justify doing so in the future, even though I believe we don’t have such a common currency symbol for satoshis.

While I have proposed a couple symbols myself in the past, I would like to second that it should probably remain out of scope for this proposal, as debates about a satoshi symbol tend to consume other topics and not converge.

0ceanSlim commented at 11:42 am on May 1, 2025: none

Actually before proceeding I want to address this comment on the mailing list

From Lucas André:

Maranatha!

I propose a small addition that could improve this, particularly for users relying on assistive technologies (like our boi Hal Finney once did).

Specifically, I suggest adding a short section on accessibility and voice/UI guidance. Your proposal does a solid job, but it doesn’t yet cover how these should be handled in screen readers, voice assistants, or accessible interfaces. Below is a proposed section that could be added under “specification” or introduced as a new non-normative section.

To ensure clarity and inclusiveness in UIs and assistive technologies, the following recommendations apply:

Pronunciation: The abbreviation “sat” should be pronounced as /sæt/, and “sats” (plural) should be pronounced as /sæts/ (rhyming with “cats”) by screen readers and voice assistants. “Satoshi” (singular) is pronounced /səˈtoʊʃi/. “Satoshis” (plural) is pronounced /səˈtoʊʃiz/.

Singular vs. Plural: “1 sat” should be read as “one satoshi” and “100 sats” as “one hundred satoshis” to preserve correct pluralization and meaning. When reading aloud:

“1 sat” → “one satoshi” → /wʌn səˈtoʊʃi/ “100 sats” → “one hundred satoshis” → /wʌn ˈhʌndrəd səˈtoʊʃiz/

Readable Formats: Prefer full terms in accessibility modes (e.g., “satoshis” instead of “sats”), and group digits to assist parsing (e.g., “12,345” instead of “12345”).

Contextual Labels: Interfaces should use clear alt-text or aria-labels such as: alt=“Transaction fee: 14 satoshis per virtual byte”. This enables screen readers and other assistive technologies to accurately interpret and communicate the content.

If this makes sense, I’d be happy to help refine it or adjust to fit the structure if necessary.

Peace, Lucas.

14+== Abstract ==
15+This BIP proposes to formally define and standardize Bitcoin's smallest indivisible unit (1/100,000,000 of a bitcoin) as "satoshi" (singular) or "satoshis" (plural), with "sats" as the standard abbreviated form. This standardization aims to improve clarity in communication, user interfaces, documentation, and development across the Bitcoin ecosystem.
16+
17+
18+== Motivation ==
19+As Bitcoin adoption grows, the need for a clear, standardized terminology for its subunits becomes increasingly important. Currently, there are various terms used to refer to Bitcoin's smallest unit (1/100,000,000 BTC), including "satoshi," "satoshis," "sat," "sats," and sometimes simply expressed as decimal values of bitcoin (0.00000001 BTC).

I would not oppose merging as it is, but I don’t think the assistive tech additions contribute to the proposal. They are quite general comments/recommendations that apply to the good design of all human interfaces, not only bitcoin-related. Although important, they dilute the main contribution which is formally defining bitcoin subunits.

Sorry I didn’t seem this earlier, the pace of change in this proposal is quite swifty.

69 The term "satoshi" and its abbreviation "sats" have already gained widespread adoption within the Bitcoin community. This BIP seeks to formalize this existing convention rather than introduce new terminology.

73 The proposed bitcoin/satoshi (or BTC/sat) standard follows the established pattern of major world currencies, which typically have a primary unit and a smaller subunit. Most notably, the United States dollar—the world's primary reserve currency—uses dollars and cents in a two-tier denomination system. This familiar dollars/cents model has proven effective and intuitive for everyday transactions across different scales.
74 The bitcoin/satoshi system mirrors this approach while accounting for Bitcoin's higher divisibility requirements. Furthermore, the phonetic similarity between "sat" and "cent" creates an intuitive bridge for newcomers to understand Bitcoin's smallest unit, making the learning curve less steep for those familiar with traditional currency systems. This natural familiarity leverages existing mental models of how currency denominations work.

this line is going to age a much very very soon bro

it’s good to write for the present, but better to write for posterity

I’m not sure I follow? You mean traditional currency will be irrelevant in a world where Bitcoin is the standard? I mean if that’s the case we just call it money if there is no other alternative. Or do you mean something else?

This was added to explain the rationale for the naming convention.

Or do you mean less praise for Satoshi as he becomes less relevant over time? I agree Satoshi isn’t some God like figure and I could tone down the praise. He does warrant being acknowledged though of course.

I will try to think a way to salvage this, but IMO I think the whole paragraph could be simple burninated

127+Thanks to the entire Bitcoin community who has organically adopted the terms "satoshi" and "sats" over the years, and to Satoshi Nakamoto for creating Bitcoin with its precisely defined subdivision structure.

the community line is very great, the Satoshi line is not bad but is a bit cringey

0ceanSlim commented at 9:37 pm on May 5, 2025:

Would it be better to just say thanks to Satoshi for creating Bitcoin and leave it there?

katesalazar commented at 9:47 pm on May 5, 2025:

0Thanks to [WHO_INVENTED?] for coining the term "satoshi" with the meaning herein informed, and to the community for having converged on using "satoshis" and "sats" as such in a frictionless and peaceful way.

isn’t it a bit cringey? I left yall a suggestion
