Good points as to why we should move away from proof of work blockchains.

You could also say that the BTC/USD rate is proportional to the amount of interest...

Some problems I am excited about cryptocurrency fixing: - Sending money across borders. - Decentralized exchanges that actually charge fair fees, unlike the centralized exchanges o…

Reminds me of an ongoing & heated debate about T. rex -- Did the T. rex have lips?

You are right, I lied a bit to oversimplify :)

Just wanted to add since I didn't see this covered in other comments yet -- TOTP and any sort of one time code authentication are just as phishable as passwords. Perhaps the bigges…

The epoxy can't be physically removed without great risk of ripping off the electronics on the underlying circuit. The epoxy can be chemically dissolved, but would deteriorate the …

To add to this, we would like to be able to run open source & update-able code and leverage EAL certified secure elements. Chips like the SE050 have recently come on the market and…

New in V2: - More secure microcontroller supporting secure boot, PUF, flash encryption, etc. - Firmware rewritten in rust. - Much more robust and durable construction. - Touch butt…

Hi There! I'm part of an open source based startup and we'd love to get some help with our web design. We sell physical FIDO2/U2F security keys, for strong authentication on the we…

Some bootloaders can be really simple. Here is one I wrote recently for my security key product (this particular code is for an ARM M3). https://github.com/SoloKeysSec/solo/blob/ma…

I agree, you could do this using more traditional methods, I just think leveraging a nice printing process could save some time/effort. Some other challenges that printing solves: …

It'd be difficult to get all the holes lined up correctly

I think if we had a single chip solution, we could make it work, but since we're using 2 chips, it would be tight. I posted schematic in other comments. Maybe one "affordable" idea…

We'd love to make something small like the Yubikey Nano! Right now it'd be a bit tough, because to fit our chipset [1] in that tight space, it would likely involve making a custom …

Tomu, being a ARM M0 core, might take some time to compute ECC signatures, but it is probably fine in practice. Our code is designed to be small and portable, so I think it could e…

We are using the EFM8UB1 chip to implement the USB HID interface, then communicate with the SAM L11 via SPI. After considering many MCUs with USB interfaces, it seems to always be …
