A difference of opinions at the Bitcoin Foundation regarding the XBT proposal?

[Biodom]

First of all,

1. Mr. Matonis talks like he gives everybody else a dictat on how XBT has to to be calculated.
http://www.coindesk.com/bitcoin-needs-iso-certified-currency-code/

One XBT unit as listed and recorded within ISO 4217 would have eight subunits or decimal places to the right of the decimal point.The rationale for this is that a neutral global default for bitcoin around the world cannot deviate from the unit's representation on the block chain and the bitcoin integer in the core protocol is not changing.One bitcoin on the block chain must equal one bitcoin in the formal standards world or else processing errors would be potentially catastrophic.

Then, perhaps, the core protocol should change so XBT=100 satoshi. There is NOTHING catastrophic about this change. Mr. Matonis is NOT a computer programmer and is prone to gross exaggeration here, I believe.

Why make this change? Because it would make bitcoin much easier to handle as it will incorporate satoshi(s) as two digits post period (which is familiar to EVERYONE).

2. Mr. Matonis writings are also in clear contradiction with the Bitcoin Foundation press release of October 7, 2014.
https://bitcoinfoundation.org/press-releases/press-release-october-7-2014-bitcoin-foundation-financial-standards-working-group-leads-the-way-for-mainstream-bitcoin-adoption-2/
I quote:

The working group will deploy a consensus based process for reaching an agreement for the official currency symbol. In addition, the working group will recommend Bitcoin subunits. In a currency, there is usually a main unit (base), and a subunit that is a fraction of the main unit. Currencies today operate with two decimal spaces to the right ($1.00). In Bitcoin, there are currently eight so one could theoretically pay you 0.00000001 or one hundred-millionth of a Bitcoin. Not only is this confusing for consumers, it does not fit in existing systems and software for accounting practices.

Conclusion: What Mr. Matonis has released on 10/21 is in clear contradiction with the prior Press-release of the Bitcoin Foundation.

Suggestion: making XBT equal 100 satoshi is an elegant solution. What would be a colloquial name for XBT: market participants would decide whether to call these units bits, bitcoins (again, but not BTC) or finney (in honor of Hal Finney).

One bitcoin on the block chain must equal one bitcoin in the formal standards world or else processing errors would be potentially catastrophic.

I agree with this. People already use XBT to mean Bitcoin (because they rightly thought BTC was not a standard name). If you tell them to change the definition to XBT = 1 microbitcoin, then confusion will inevitably arise.

The fact that current accounting software can't handle more that 2 decimal places means that this software must adapt to our needs (and use µXBT in the meantime, if it's much trouble).

People should not adapt to the software. That's not how it works.

Non-mathematicians have difficulty picturing sums like 0.00014321 BTC, which would be 143.21 XBT if XBT=100 satoshi(s)
The transition would be even more seamless because people already started thinking in bits. If 1XBT=1bit=100 satoshi, it would all make sense.

I see your point, but agree with R2D221 and Jon Matonis. Don't know whether 'catastrophic' is the right word, but it would create too much confusion.

As per your example, from the small/medium business or even customer's perspective, you'll be more likely dealing with amounts ranging say between BTC0.01 to BTC100 rather than BTC0.00014321. A few examples:

BTC99.15 = XBT99150000
BTC1.456 = XBT1456000
BTC0.025 = XBT25000

To me, that doesn't look much better than 0.00014321, does it?

The problem is not scale, but terminology. XBT already has a defined meaning (= Bitcoin). You want to change the meaning of a symbol people already understand. You're going to have a bad time convincing them to arbitrarily switch the meaning rather than creating a new symbol.

No, it does not, apart from maybe for 1-10 thou people.

OK, the last example didn't really made my point, whether it's XBT25000 or XBT0.025 it shouldn't be too hard to comprehend for anyone.

My point was, too many digits will cause confusion, whether it's right or left side of decimal.

You idea offers some improvement, as it's slightly easier to deal with larger numbers than smaller fractions, but it would only work if we assume that everyone will instantly and happily switch to the new system. But we know that's not gonna happen.

So if we were to go that route, we would divide in 2 groups, one using the old (current) system and other -the new one. Total chaos.

So, as I said before, I do see your point, but it will likely do more bad than good.

Oh, no, we will divide into "Little-Endians" and "Big-Endians" (J. Swift) or worse yet, United Bitcoin Alliance vs United Bitcoin League (reminiscent of South Park)... it's inevitable  .

You guys are overthinking this.  1 bitcoin = 1 bitcoin
If you specifically say "XBT", you do so for a reason.
1 XBT = 0.000001 bitcoin

For larger transactions it makes sense to say bitcoin.
For smaller transactions or currency trading purposes it makes sense to say XBT.
XBT is not widely used now so I don't think it will create mass confusion. 

[PolarPoint]

I don't really care how they call each subunit. My bitcoin will always have 8 decimals and called BTC.  

There are voices who opt for "Bits" instead of "uBTC". If "XBT" stands for Bits and not Bitcoin, it makes sense and could make bitcoin more user friendly.

ISO standards is for industries that it produces tangible things.

One issue is that people in Japan are used to spending these large amounts of units of currency while the vast majority of the rest of the world is not. I don't think spending this large of a unit of currency would ever catch on in much of the industrialized world.

OK. First, he says that Bitcoin = Bitcoin so that we don't cause confusion. Then, he says that 8 decimal places are still confusing for common people, and that the working group will recommend Bitcoin subunits.

I don't see how that's a contradiction. He still wants to maintain Bitcoin as the main currency, just not use the 8 decimal places as the common subunit.

We still get to name it, but try not to pick a confusing name. Why is that so hard?

Bitcoin Foundation: "In a currency, there is usually a main unit (base), and a subunit that is a fraction of the main unit. Currencies today operate with two decimal spaces to the right ($1.00). In Bitcoin, there are currently eight so one could theoretically pay you 0.00000001 or one hundred-millionth of a Bitcoin. Not only is this confusing for consumers, it does not fit in existing systems and software for accounting practices."

If you put two and two together, basically, Bitcoin Foundation says that proposed by Matonis XBT format WILL BE confusing to consumers, and instead, they propose a main unit and a subunit (with implied 1:100 ratio). This is there in black and white, so I don't understand your argument.

Me too. I started supporting this proposal sometime earlier this year. It still feels right.

It also seems opposition is much less fierce than last time the topic bubbled to attention.

I can't quite get myself to like that.

[pawel7777]

There are voices who opt for "Bits" instead of "uBTC". If "XBT" stands for Bits and not Bitcoin, it makes sense and could make bitcoin more user friendly.

I'm against denominating bitcoin (when XBT=Bitcoin=100 satoshi), but the above could work.

From the quoted article:

...
These existing minor units of bitcoin will be submitted in the ISO application for XBT and it is not required for all of the individual minor units to be submitted.
...

So if XBT is registered as 'Bit', 'Bitcoin' could be submitted as 'major unit' and 'satoshi' as 'minor unit'. That's pretty important, otherwise it would be very strange if the word 'Bitcoin' was not mentioned anywhere in the application.


But still think it could cause unnecessary confusion. After all, if XBT=Bitcoin, it's not really stopping anyone from using 'millibits' or 'bits'.

[Q7]

For me the issue of adoption comes first. Not sure about others but maybe we can just reach a consensus later part. So if i understand correctly, if follow the ISO standard 1 btc will essentially mean 1 000 000 XBT. I don't see an issue here as most people are holding a fraction of a complete coin so the number actually doesn't sound too big

[KingOfTrolls]

It also seems opposition is much less fierce than last time the topic bubbled to attention.

This is demonstratably false:

Last time this topic came up "bits" was leading the polls, e.g. this one.
In a more recent poll, "bits" only ranked second, i.e. it is declining in popularity.



(I'm well aware that these polls are not representative. If you have any better evidence, then cite it.)

[bg002h]

I'm on the working group. There are lots of options for units to go with an ISO 4217 currency code. Would XBT = 100M satoshis (1 bitcoin) be better than XBI = 100 satoshis (1 bit)?

If XBT = 1 bitcoin, I don't foresee people writing 0.00098 XBT to describe the cost of bubblegum. People _might_ write 980 XBI though.

I think we need more community input on this choice. Can we get two currency codes? Doubtful, but is worth discussing.

Another related idea that I think needs community input is getting a Unicode currency symbol(s). We are all used to using BTC for bitcoin and some are starting to use ƀ for bits...unfortunately, a capital ƀ is Ƀ, which is also used for 1 bitcoin. Nothing like a capitalization error to cost you 1 million times more than you wanted to spend!

Should we try to get Unicode characters for 1 bitcoin and 1 bit? Just bits? Just bitcoin?

A benefit of using 1 bitcoin as a standard is that the symbol µ is separately encoded in Unicode from the Greek letter μ (which case folds to the Greek letter M).

Therefore, 1 µXBT and 1 µBTC shouldn't accidentally change value at the whim of a shift key.

I think a wide discussion is needed. Bitcoin is different. It's global. Different cultures would likely have different opinions and we should push for standards that meet all those needs.

What's actually wrong with XBT=1BTC (100m sats), since we could popularise usage of millibitcoin (BTC0.001)? It's easier to comprehend by average Joe, since it's closer in value to $1. So the chewing gum would be mBTC0.98, which looks better than 0.00098 or 980.

With XBT=100 sat, the brand/name of "bitcoin" would suffer a serious blow. If all the major players start using terms "XBT" or "bits", there would be no practical use for "Bitcoin". In terms of brand awareness, we would have to start from scratch. Loads of people worldwide heard of 'bitcoin' (even if they don't fully realise what it is), if the name is changed (and also the exchange rate etc) they probably wouldn't even know that XBT (bit) and Bitcoin relate to the same thing.

Many people will now protest that "XST" bears no resemblance with our "brand name" Bitcoin.

To those I will respond:
The Chinese currency Renminbi bears no resemblance with "CNY" either, even though the latter is its official ISO 4217 code.
So, as the most populous country in this world is able to cope with that, the rest of the world can understand it, too.


The advantages of using satoshi are (at least) threefold:
The unit "satoshi" is unambiguously defined, the term has developed naturally, and it is universally accepted, even by those who prefer a different unit.

These are three important properties for standardisation.

I concur. There should be only two currency codes, and at the extremes, no half measures to confuse the fuck out of average people. The largest unit, 1 BTC=XBT, and the smallest subunit, 1 satoshi/0.00000001 BTC=XST.

We need to lock in the smallest subunit, the furthest point of divisibility. If 1 XST ends up being exchanged to $0.01 USD, then 1 XBT will be equal to $1,000,000 USD.

Clients should allow setting XBT or XST as the default display (with appropriate warnings), and pricing can be displayed both ways in the global marketplace. No changes in the way TXs are constructed in the background would be necessary.

I have over 20 years experience working on FX systems, and I strongly advise that the primary objective here, with the standards authorities, is:

[An official ISO code] = 100 satoshis.

If Bitcoin is to remake the mainstream financial world, this will give it a massive advantage, but obtaining any other official standard will be of little benefit in comparison.

Can we get two currency codes? Doubtful, but is worth discussing.

If we can get two currency codes, that would be excellent. However, the standards people would want to see them alphabetically contiguous, so XBT:XBU could fly, but XBI:XBT is improbable.

[pequelore]

For me the issue of adoption comes first.

Agreed. How can bitcoin be a success if people doesnt know what it is?

[Biodom]

I'm on the working group. There are lots of options for units to go with an ISO 4217 currency code. Would XBT = 100M satoshis (1 bitcoin) be better than XBI = 100 satoshis (1 bit)?

I have over 20 years experience working on FX systems, and I strongly advise that the primary objective here, with the standards authorities, is:

[An official ISO code] = 100 satoshis.

I totally agree that the objective is [An official ISO code] = 100 satoshis.
and everything else is secondary. If you make the minor unit a 0.00000001 of the major unit (in proposed standard), then you accomplished nothing toward the ease of use/acceptance by a large % of the population. 90-99% of all people would not want to deal with eight numbers after period. People, however, will decide how to call the official unit in day-to day life.
CNY has nothing in common in pronunciation with renminbi/yuan.

[KingOfTrolls]

90-99% 100% of all people would not want to deal with eight numbers after period.

Fixed that for you. It's 100%.

It is empirically proven that the human brain prefers to deal with positive integers.
This can be easily seen by when children are tought integers versus decimals in elementary school. Even some animals are capable of using integers, yet none are capable of using decimals.

An international currency like Bitcoin deserves to have the easiest conceivable system for measuring value, i.e. plain integers.


Existing financial traditions might differ; it is especially notable that western cultures prefer to have two decimal places to the right of the point, while arabic cultures prefer three decimal places. African cultures, on the other hand, use division by five, i.e. one decimal place.

Bitcoin oughts to have a system that allows each culture to establish their own currency units, while still having one common unit for all of them. My proposal is to use the smallest possible denomination for international exchange, while still allowing higher denominations for use in individual countries, according to their respective financial traditions.

[An official ISO code] = 100 satoshis.

[An official ISO code] = 100 satoshis.

This option is only viable if we have consensus on what the [bracket expression] will substitute for.

Don't think two ISO codes are possible. After all, it's the same currency.

Each country has 26 codes reserved for it, including island states with an economy smaller than that of Bitcoin's ecosystem. Some countries have used more than one, such as Turkey when they shifted the decimal 6 places. X-codes are a different case however, and yeah, it is not that much more useful to have 2 codes than one.

Only this matters. [An official ISO code] = 100 satoshis.

[teukon]

I'm on the working group. There are lots of options for units to go with an ISO 4217 currency code. Would XBT = 100M satoshis (1 bitcoin) be better than XBI = 100 satoshis (1 bit)?

If XBT = 1 bitcoin, I don't foresee people writing 0.00098 XBT to describe the cost of bubblegum. People _might_ write 980 XBI though.

I certainly feel that XBT for 1 bitcoin is a better choice than XBI for 1 bit, mainly because the term "bitcoin" is far better established (one can even look it up in the dictionary).  Currency codes are very much a realm for formality, accuracy, unambiguity, and stability; XBI for one "bit" is simply not appropriate today given the youth and contention surrounding the term.  If the 100-satoshi unit is desired (e.g. for decimal point-related issues) and the working group wants to push this now then I think the only appropriate term to build around is "microbitcoin".  This is not the end of the world (The formal UK currency name is the cumbersome "Pound sterling" yet, GBP works and people get by with slang such as "pounds" or "quid" in everyday situations).

People are unlikely to write "0.000 98 XBT" or "980 XBI" in my opinion but they may well write "980 bits".

I think we need more community input on this choice. Can we get two currency codes? Doubtful, but is worth discussing.

Just in case the working group hasn't seen it, here's an Old, short, Bitcoin Foundation discussion on the topic.

Another related idea that I think needs community input is getting a Unicode currency symbol(s). We are all used to using BTC for bitcoin and some are starting to use ƀ for bits...unfortunately, a capital ƀ is Ƀ, which is also used for 1 bitcoin. Nothing like a capitalization error to cost you 1 million times more than you wanted to spend!

Should we try to get Unicode characters for 1 bitcoin and 1 bit? Just bits? Just bitcoin?

A benefit of using 1 bitcoin as a standard is that the symbol µ is separately encoded in Unicode from the Greek letter μ (which case folds to the Greek letter M).

Therefore, 1 µXBT and 1 µBTC shouldn't accidentally change value at the whim of a shift key.

I quite like the µBTC idea.

Another thought: Perhaps a "µ" with a bar through it, "µ" say, would be easier to get given that "₥" for a mill already exists and is currency agnostic.  I could certainly see prices like "1500µ" (or "µ1500") being commonly read as "fifteen hundred bits" but also sometimes "fifteen hundred mikes" or "one point five mills".

I feel worth stressing a second time is that, given the current upset surrounding the 100-satoshi term, it might be wise to simply work on a currency code for the "bitcoin" unit for now, leaving the issue of the smaller unit to settle for a few years.

Disclaimer: While I've honestly tried to be unbiased and logical, it's no secret that I openly oppose the term "bit" for 100 satoshis.

For those who are FOR or AGAINST bits:

Why can't we recalculate bitcoin as=100 satoshis, then we end up with just bitcoin [XBI or XBT=100satoshi] and satoshi itself.
Why some people so hung up on bitcoin being 100mil satoshis? This change would be very easy to implement.

I agree. I think that redefining how we measure Bitcoin (in terms of terminology) would wreck havoc on bitcoin related commerce, as people would be confused as to exactly how much value is being asked for when someone is selling a certain product or when negotiating a price, this would result in people not wanting to deal in bitcoin

Thx for the input. Is the two decimal bits a better choice than the 8 decimal bitcoin? The advantages of two decimal places is obvious...the advantage to using bitcoins is you could prepend a micro symbol that doesn't case fold to a letter that could be interpreted as M for mega...Unicode has a separate SI prefix micro.

sorry about "everybody", it was presumptious of me. I guess, I meant everybody who ever traded actual stocks on the stock market.

What I propose is simple: do a virtual 1:1,000,000 stock split of bitcoin (mathematically) to 21 trillion units, then call these units (each=100 satoshis) as you please (either "bitcoin" still-which I would prefer- or "bits" or even something else). What symbol to give them is largely irrelevant because they will be the winner due to greatly improved ease of use and adherence to two decimals after period standard for most currencies, which is much more familiar to people outside of the current bitcoin community.
However, after any stock split, you still call the stock by the same three-four digit symbol (hence AAPL for Apple) and full name, but the the number of shares/units changes, obviously. Nobody calls it redefining, but it is admittedly so in the narrowest sense (you redefine the number of outstanding shares that company has in a stock split).

From a practical point it is also simple: define a major unit as 100 satoshi (not 100,000,000) and make satoshi a minor unit at 1:100 of the major unit.

Actually, J. Allaire of Circle did refer to 2.1 quadrillion satoshi or [units] in several public speeches.
Besides, with 21 trillion units you can start working toward unity(equality) with $$ since high tens/~hundred of trillions is where world GDP is.
Why would this be a collapse-no, instead of artificial scarcity it would be seen as an adequate number of units and we will work from low value per 100 satoshi to higher.
I can predict that this alone will cause a dramatic increase in activity because people will perceive having much more [units].

[Goldmundo]

One important thing to note with regards to the OP, Mr. Jon Matonis seems to like to express his personal opinions without being careful to not sound like he is speaking in the name of the Foundation. So, whatever opinions he expressed in the said CoinBase article are his personal opinions and not necessarily that of the Financial Standards Working Group. While the group itself does not yet have an official recommendation, it seems to me (and this is my personal subjective perception) that XBT = 100 satoshis = 1 bit is the prevalent option both within the group and wider community.

I believe if we are going to have this worldwide currency and have people really start using it in every day life, it definitely cannot be expressed with 8 decimals. Reasons are technical, psychological, accounting related, all mentioned already.

It seems that there are some real obstacles within the Bitcoin system as it is at the moment. But I am honestly hoping that we will reach consensus on changing the system to be future-proof rather than sticking with the status quo thus crippling the growth of Bitcoin, potentially fatally.

As for the idea of having two units, one for ISO and another for display, I think this is a confusing half way solution that will make bitcoin different from other currencies and thus more difficult to understand and embrace. I can't stress enough: the number of people currently using bitcoin is a tiny tiny group which could very well be considered a beta testing group. There should be no worries of causing confusion by switching to bits (or bitcoins worth 100 satoshis each) as the main unit on all levels. Why? Because all the people who know what is going on will make the switch very easily, while all the people who don't know what's going on couldn't care less and it will make no difference to them.

My mother started using bitcoin recently. If her balance on Circle changes from 0.5 bitcoins to 500000.00 bitcoins while the displayed US dollar amount stays more or less the same, I guarantee you she will not even notice. And even if she does, she might ask me "How come I now have 500K bitcoins? Does it mean I'm now insanely rich?" And I'll say "no mom, they just changed the denomination unit" to which she will reply "ah, ok." End of story.

I don't even want to start thinking about explanations to new comers when they would start asking how come there is this big unit called XBT which I see on trading sites, but when I log into my account on Coinbase I see these bits.. What are the two? Why do we have both? And on this third site they are using some uXBT, and then I also saw somewhere amounts in milibitcoins, is that also bitcoin just with a different name? etc etc..... It's such a mess! It's already difficult as it is to explain to people some things about bitcoin, let's make it easier, please, not more difficult.

It may be useful to quote Jon Matonis' comment from that article. He has some solid points:

Thank you all for engaging on this important topic. When it comes to XBT and where to set the decimal, I don't think there is a right or wrong answer --- it's a matter of perception and
managing trade-offs and people will sit at different places along that spectrum.

So, here are my detailed reasons for maintaining XBT as a one full bitcoin (1.00000000):

a) We get one shot at setting XBT and minor units within the ISO standards body, so we should not base a plan around what makes "visual" sense at the time (Zimbabwe did not keep going to the ISO for re-pegging as they massively added zeroes. If gold goes to $10,000 per ounce would you recommend adjusting base unit to grams?);

b) The white paper from Satoshi references 21 million as a finite limit for bitcoin issuance. Although he entertains adjusting commas and decimal displays in his post, the public perception and the 21 million limit has taken on a greater importance with the financial world than initially realized. Changing it now would undermine those perception gains. Moving the decimal point to bits would change the finite limit to 21 trillion "bits" or 2.1 quadrillion "satoshis" definitely not inspiring to the economic notion of scarcity (CNBC TV quacks will say the new limit for bitcoin is now 21 trillion!);

c) For better or worse, pricing in currency units implies relative scarcity of that unit. Italy was constantly ridiculed when it required 2,000,000 lira to purchase an everyday household item. They are not the only example. Sure, a newbie can acquire more bits, but it trivializes
the pricing mechanism;

d) XBT is already quoted as 1.00000000 on respected forex sites, such as XE.com, Bloomberg, Reuters Eikon, and CNN. Even Oanda.com quotes it this way although they still use BTC. Moving to a "bits" expression would start to make bitcoin (XBT) a joke currency like Dogecoin;

e) Some will say it's just as a display. But the ISO decimal setting will be more than a display --- it will be the default in the legacy financial world. Instead of changing that default in the reference implementation and instead of changing 1XBT = 1.00000000, I recommend
all other wallets/apps select their preferred display, of which there will be many.

Since when currency units imply scarcity? Currency units imply utility in everyday life. World GDP is ~90 trillion $$.

Well, respected forex sites can reprogram their computers

Additional comments:
1. having 21 trillion XBT[XBU]/[new]bitcoin/bits=100 satoshi will bring total number of bitcoin major units closer to major nation GDP values and would facilitate:
a. more commerce simply because everyone will have more units. This is is trivial mathematically, but beneficial psychologically.
b. easier understanding from people who are known to be unable to properly process multiple digits after the period in value evaluation.

2. Bitcoin can work toward eventual unity (equality) with the dollar, yan or other major currency (yen to yuan to $ to euro)

3. If bitcoin is a currency, can Mr Matonis provide an example of a currency that is valued at ~$300-400? There is none, of course, so this historical precedent works against bitcoin having 8 digits after the period.

Does anyone has actual knowledge regarding ISO application?
Do we know for sure that it is possible?
Who will prepare/submit the application? Bitcoin Foundation?

Also, how does the approval process work? Is it:

1) There are very specific criteria, if those are met - application is automatically approved' or
2) Approval/decline is solely an ISO's decission (even if criteria are met, they can reject the application)?


In either case, if the criteria are currently met (such as Bloomberg/Reuters reporting, exchanges, international payments and recognition) - these are met by the bitcoin in it's present shape (8 decimals), not by 'bits' or bitcoin=100 satoshis.

I can't imagine ISO approving application for XBT=bitcoin=100 sat based on multiple factors, including Bloomberg reporting on bitcoin, while Bloomberg reports on bitcoin being 100,000,000 sat.

Seems to me that forcing the denomination idea can jeopardise the application.

If you want XBT= bit or bitcoin=100 sat, isn't the correct way of action first to make everyone switch to 'bits' and then apply for the ISO code?

Because if it is a commodity, then there are commodities priced as high or higher per unit (gold, platinum, etc.)
However, there are no currency units priced in hundreds of US dollars.
My argument was to refute opinions based on prior anecdotes (how everyone laughed at Italy, whether we will measure bitcoins in grams or Zimbabwe-all provided by Mr. Matonis in one go)

Essentially, yes, but you don't have to call these units bits "officially".

the term "bits" is not important in the ISO code discussion. The benefit of ISO currency codes that they provide a standard for inter-system communication, financial data storage and transmission from computer to computer around the world. ISOs do not need to be seen by the public. People use US$ informally instead of USD, and A$ instead of AUD.

People who want to see BTC and the existing Bitcoin amounts 1.23456789 on their screens, can still do so, even if this amount is stored as XBT 1234567.89 in an accounting system.

Reading what Jon Matonis has written, makes me think that he needs to talk more with IT people who work on accounting and payment systems.

Interesting.  Do you have a source for this?

Sorry, no, just personal experience from interacting with standards people during securities issuance.

[KingOfTrolls]

I tried to compile an overview of possible choices for an ISO 4217 application, and assigned codes for easy reference.
Here's the list, ordered alphabetically:


[BI2] — Apply for 1 XBI = 100 satoshis, with one subunit and two decimal places.

[BT2] — Apply for 1 XBT = 100 satoshis, with one subunit and two decimal places.

[BT8] — Apply for 1 XBT = 100000000 satoshis, with various subunits and eight decimal places.

[BU2] — Apply for 1 XBU = 100 satoshis, with one subunit and two decimal places.

[ST0] — Apply for 1 XST = 1 satoshi, with no subunits and zero decimal places.

[UB2] — Apply for 1 XUB = 100 satoshis, with one subunit and two decimal places.



I think it would be beneficial if we work through the list of choices and discuss the pros and cons of each item individually.

Here are my thoughts:

There is a serious problem with variant [BT2] because the currency code XBT is already used on a lot of sites with the definition 1 XBT = 100 million sats. When the ISO committee sees that the proposed unit is grossly incompatible with current practice, they will certainly reject the application.
This means that all those sites would have to switch to the new definition 1 XBT = 100 sats before we can submit the application. This switch would require a huge organisational effort. There would need to be consensus for a specific "switch date", when the old definition (1 XBT = 100 million sats) gets replaced with the new definition (1 XBT = 100 sats). Given Bitcoin's decentralised nature, it would be hard (if not impossible) to find consensus for any particular date.
And even if the switch is successful, people would wonder how to pronounce the unit XBT: Those people who traded on sites that just switched would certainly perceive this as a stock split, and thus call it "new bitcoin" (versus "old bitcoin" with previous definition). The "bits" proponents, on the other hand, would call it "bit", while still refering to 1 million bits as a "bitcoin".
Some people would accept this re-definition, others won't. I think it is likely that this will create a schism in the Bitcoin community. It is also likely that certain players will use this situation to spread fear, uncertainity, and doubts about Bitcoin.
Even if all of the above difficulties are successfully handled, this would slow down the standardisation process for additional — I guess — six to twelve months.

A much more frictionless approach would be [BT8]. In this case the standardisation process would be quickest, because the code XBT is already widely employed and it would be (comparably) easy to convince the ISO people to officialise this de-facto standard.
The big disadvantage here are the eight decimal places. Most financial software allows a maximum of four decimal places. Eight is too many. It is also very inconvenient for human users, thus requiring any front-ends to support a customised (non-ISO) display.

The options [BI2], [BT2], [BU2], and [UB2] have in common that they would give preference to one of the many names for 100 satoshis, which means that the other groups would be dissatisfied and flamewar against it. Finding a consensus here seems to be very difficult, maybe impossible. This would also slow down the standardisation process for some time, because one needs to wait for consensus to emerge.
The advantage here is that quite a lot of currencies (especially in western cultures) use two decimal places, too, which means that this would make Bitcoin more familiar to users of these currencies.

Lastly, the option [ST0] doesn't have a "B" in it, which requires people to understand the distinction between a currency (like "Sterling", "Renminbi") and its unit (like "pound", "yuan"). This proposal has the advantage that there are no naming issues, and no conflicting meanings, i.e. the standardisation process would be frictionless. It wouldn't create any kind of schism in the community. It also has a kind of intellectual purity because values are expressed in exactly the same format as they are transmitted by the protocol and stored in the blockchain, i.e. plain integers.
The disadvantage here is that prices will often be expressed in thousands of satoshis, probably written as "k sat" (with the "k" being postfixed to the number) or "ksat" (with the "k" being prefixed to the unit).

Because if it is a commodity, then there are commodities priced as high or higher per unit (gold, platinum, etc.)
However, there are no currency units priced in hundreds of US dollars.

But there are a few currencies worth only 1/100s(even the JPY) or even 1/10000s of the mighty USD, so why not the other way round?
This argument is not viable.

[bitnanigans]

Having 2 decimal places for the ISO standard makes sense, and it doesn't affect the conversion or other factors.

Just for perspective, there are 1000000 Zimbabwean Dollar notes, so having values like 1000000XBT to represent 0.01BTC isn't too far-fetched.

[CIYAM]

This seems like a *storm in a teacup* to me.

No-one is asking anyone to change the way that their preferred Wallet displays things - the idea of an XBT code is just for *standards compliance* so whatever is *normal practice* is of course what should be used for that (do most people concern themselves with XAU when talking about gold?).

Then people will get even more confused I think.. 100million will be 1 btc, while 1million seems more logical. I say we go with 1000 mbtcs = 1 btc, not too large not too small, just perfect.

[gafter]

I see your point, but agree with R2D221 and Jon Matonis. Don't know whether 'catastrophic' is the right word, but it would create too much confusion.

As per your example, from the small/medium business or even customer's perspective, you'll be more likely dealing with amounts ranging say between BTC0.01 to BTC100 rather than BTC0.00014321. A few examples:

BTC99.15 = XBT99150000
BTC1.456 = XBT1456000
BTC0.025 = XBT25000

To me, that doesn't look much better than 0.00014321, does it?

Numbers larger than 999 are generally presented with commas for readability. There is no convention for digit separators for numbers less than zero. So your comparison should be

BTC99.15 = XBT 99,150,000
BTC1.456 = XBT 1,456,000
BTC0.025 = XBT 25,000
BTC0.00286 = XBT 286

Only the last two of these numbers is in the range of realistic daily transactions (e.g. song download or lunch), which are the transactions the display unit should be optimized for.

[pawel7777]

First of all,

1. Mr. Matonis talks like he gives everybody else a dictat on how XBT has to to be calculated.
...

Biodom, good news for you. Jon Matonis resigned.

The time has come for me to resign as Executive Director of the Bitcoin Foundation. Thank you for all of your passionate support! More soon.

[Klestin]

OP has missed the entire point. The number of digits after the decimal is currently defined as 8. This could change at a later date to 10 or more digits, to support a world in which the exchange rate (or other factors) calls for finer delineations.  If/when that happens, the magic "2 digits to the right" that OP is after will go away anyways.

The number of digits to the right of the decimal is in many ways arbitrary. Changing it is unlikely to prove controversial.

However, the location of the decimal is absolutely not arbitrary and is extraordinarily unlikely to ever change. If you have 1.1 Bitcoin today, you will (barring spending) have 1.1 Bitcoin tomorrow. This is the base promise of Bitcoin. 1.1 will not become 1,100 any more than 21 million will become 21 billion.

With this in mind, 1 XBT = 1 Bitcoin seems to be the only logical choice.

In any event, XBT is very unlikely to replace "Bitcoin" in everyday verbal usage. If you want the world to begin speaking in uBTC/mBTC/bitc, price your merchandise accordingly.

I don't even think this should be a debate. Every ISO currency makes use of 2 decimal places.

[KingOfTrolls]

This is simply wrong:

https://en.wikipedia.org/wiki/ISO_4217

There are hundreds of millions of people who use currency which is not subdivided into hundredths. Why would they want to adopt two decimal places, just because bitcoin?

An international standard needs to treat all peoples equally. I think we should choose the lowest common denominator (i.e. the smallest possible denominational unit) as a compromise between the diverse financial traditions.

MOST people are used to 2 decimal place currencies. So by your own comment, they need to be considered.

And satoshis are too ridiculously small to be useful.

As the wikipedia article mentions:

The code JPY is given the exponent 0, because its minor unit, the Sen, although nominally valued at 100th of a Yen is of such negligible value that it is no longer used.

Some currencies do not have any minor currency unit at all and these are given an exponent of 0, as with currencies whose minor units are unused due to negligible value.

[KingOfTrolls]

MOST people are used to 2 decimal place currencies. So by your own comment, they need to be considered.

Yes, everyone needs to be considered. The only clean solution here, to make it right for everyone, is to hide the ISO 4217 code in the back-end whenever possible, and display to the user whatever their locale settings are. The average wallet software should allow this kind of flexibility.
This way the ISO code would become a pure technicality for low layer applications. It makes sense to use the same unit as used in the blockchain / by the protocol then, doesn't it?

How is that any different than µBTC?

No. The purpose of an ISO is to help make bitcoin amounts easily represented in the world's non-bitcoin, existing, mainstream/legacy financial/accounting systems.
A 2dp code achieves this best. In fact, 99% of them expect it.
