Coinkite ColdCard Mk4 Review

[nvK]

Imagine Bitcoin developers started changing BTC open source code to CC after first shitcoin forks showed up  

That wouldn't be possible there are thousands of contributors, all would have to agree. CC is largely single source (us), the very few external contributors had no objection.  

The cloners were very careful with their github tricks, but regardless think what you want.

Someone could correct me if I am wrong, but I think that you also didn't release your Seed XOR (version of Shamir Secret Sharing) as open source, just showing how wrong your thinking is.
But hey, do whatever you think is best for your product, if you are selling better than ever like you say, you have nothing to complain about.

We have a ton of FOSS work done, funded and contributed, under many different licenses.

Regarding the SeedXOR, XOR is standard computer operation not much to license not license. Within 2 minutes I was able to find implementations on github https://github.com/Marcaday/SeedXOR (did not review or recommend)

All the instructions for you to implement are here https://raw.githubusercontent.com/Coldcard/firmware/master/docs/seed-xor.md

You and I are free to choose our licenses for our project.

The intention is Commercial Limitation; ie cloning the whole code base and starting a competing product as it was done ^{[emphasis mine]}.

Would you care to elaborate about that cloned product?
I heard rumors about a wallet that I really like, so looked into that, compared code bases and didn't find them to be identical or similar at all.
Also lots of changes and features that ColdCard doesn't even have, so that can't be it. I'm intrigued to see who actually made a CC clone.

When altcoins started popping up, there were no thousands of contributors yet, though.

Lots of git trickery to confuse the diffs, removal of comments, etc... heck their Ad image is all the code we wrote 

Anyways, waste of time. Good luck to them.

You cloned and used parts of original Trezor open source code, and that is ok because they are the first original hardware wallet, and now you are bitching that someone else used and changed your open source code.
I found that extremely egoistic and hypocritical, but you can do whatever you want, it's your product.
Passport released everything including hardware as open source, and they used totally different hardware than Coldcard, so you are obviously going in totally different directions.
Good luck to both of you.

There was not Trezor "clonning", you maybe unware that we also contributed to mod-crypto. That was the only lib shared with trezor, many share that lib few years back. It is the norm in any industry to share the same crypto libs, we have since moved to libsec256k1 maintained by core.

I am really sick of hearing you bitch all the time, but since you want to go this road I promise to dig deep and release everything about this.
First thing I am posting one of Coldcard tweets from 2018 when you released firmware as open source... but you used Trezor GPLv3 code, that you didn't acknowledged.
It's ok to say that I don't know what I am saying (because I am just an amateur) but you claim that Trezor main dev PavolRusnak is lying.

I've further talked to him and he understood that CC was not a clone, which he thought was at that time.

You seem very angry, just don't use CC.

There is no reason for me to be angry for exposing constant lies of  hypocritical egoistic guy who thinks he invented wheel all over again
I sure won't use CC, thank you for your smart suggestion, and I see you know very well how to rename repos and do git trickery cloning

For those of you still using the older ColdCards (mk2 and mk3) there's a new firmware update that fixes a bug that appeared when signing transactions. 

https://coldcard.com/docs/upgrade

Mk3: Version 4.1.8 - Jun 19, 2023
Bugfix: "Validating..." screen would be shown twice in some cases. Improves signing performance.
Bugfix: Reproducible builds corrected.
