In many countries, courts have ruled that Bitcoin and other "crypto-assets" can be considered digital property. Even in China, where many crypto-related (commercial) activities are banned.
Now we have the situation that some people are proposing changes to the Bitcoin software like the so called "BWP[1]-110" or "The Cat" that would confiscate some coins. There are also proposals related to the "Quantum computer threat" which would inhabilitate potentially vulnerable coins, for example those in P2PK outputs.
If such a proposal was to get successful (I hope it never is!) could then the people who lost their Bitcoins take legal action?
And against whom?
- Against the developers, who implemented it? I think if the confiscation was accidental due to a bug (and thus potentially reversible), this doesn't sound "correct", as it could be considered part of the risk if you use open source software. But proposals like BWP-110 are pursued in full awareness that they will confiscate coins. And "The Cat" even has confiscation as a goal, afaik, as do the "quantum confiscation" proposals. In these cases, I think there may be indeed a legal risk for the developers. Or could they argue that you could simply use the old version (forking away)?
- Against the miners who supported it, if it was a softfork? Maybe this is also a possibility, as these are those who are changing the protocol and who forked into a protocol which confiscates the coins. One could argue that if the proposal is only in the code, it still is only an inactive proposal, and the miners are those really "activating" the confiscation.
What do you think?
PS: If this has been discussed in another thread, I'm grateful for a link and let's continue there
