firmware VS galoy

TIP: Use the BoM as well as the schematic.

As you can see, the default firmware of Coldcard is hardcoded with values d13e and cc10. We are going to change it to make it look like a benign USB device, more on it later. First, clone the original firmware from Github: https://github.com/Coldcard/firmware We now need to edit the file called ./stm32/COLDCARD/shared/usb.py: COINKITE_VID = 0xd13e CKCC_PID = 0xcc10

Software altered? You were supposed to download from source and flash it yourself. So why did you alter it? No one other than you could have altered it! https://github.com/Coldcard/firmware

Coldcard

Consider holding long term with a solution like this. Have you ever use a hardware wallet like a coldcard

Coldcard has many other security features as well. You can find more about them online. Probably the safest hard & cold wallet on the market right now. But most people don't buy it because of their $400 price tag. But definitely worth it for anyone holding more than a pretty penny.

You can check it

it’s a cold wallet that only holds BTC

They probably did talk about Strike in the video. Jack Mallers met with the president of El Salvador and Jack's company Zap developed El Salvador's wallet named Chivo. Bitcoin Beach Wallet was developed by Galoy.

It's semi custodial solution. Basically a small local community bank leveraging LN. https://github.com/GaloyMoney/galoy

To give some technical background: yes, using Lightning (as they seem to do) for affordable BTC payments is challenging for most. As far as I am aware that is why they rely on custodial solutions [1]. People hold their money with someone from their village they trust, which is not ideal but neither is being unbanked. Down the road I could easily see this trust being spread over multiple people using multisig wallets.

The amazing thing about all this is that everyone can become a BTC "bank". You need a bit of capital but orders of magnitude less than a normal bank would require, maybe 2k$ to get started of which you might spend 400$ on hardware and fees to open some channels. The trustless nature of lightning lets you and your users then join the global payment network without asking for permission from anyone and you can engage in commerce internationally.

I think, while we are still early, that this is an awesome experiment. It will highlight the UX problems so we can fix them. Hopefully at some point all this will make sense to the average westerner too, so we can finally have a money not controlled by anyone (states, incumbent banks) again. But that might take a long time.
