There are fairly just a few threads already on this matter, however all of them concentrate on the necessity or risk for such a change. I perceive that, regardless that it’s tough and would clearly require broad consensus, including extra decimal factors to bitcoin is feasible. This query shouldn’t be about whether or not we might ever really want/need such a change.

I’m solely within the technical particulars as to why including additional divisibility requires a tough fork (or evil smooth fork) and wouldn’t be potential with a “common” smooth fork. I’d say I have already got a superb feeling why, however might not likely clarify it to another person.

I’ve considered “separating” the brand new decimal factors indirectly however that may almost certainly not work, since outdated software program wouldn’t settle for if somebody desires to spend two 10000(.5) sat inputs to a 20001 sat output. The query of how outdated software program would interpret a transaction with added decimal factors typically is the principle downside I assume.

Nonetheless, how can we ensure that there is not a chic resolution to this? Why wouldn’t it require a serious change of present bitcoin software program?
