[2017-11-02] Satoshi Labs Launches New Bitcoin Hardware Wallet ‘Model T’

[nickbelski]

This week, Czech Republic-based Satoshi Labs, launched the pre-order batch of the startup’s Trezor 2 hardware wallet called the “model T.” Satoshi Labs says even though the new Model T is an entirely new device it safely secures digital asset keys just like the prior version.

Satoshi Labs has just launched the first batch of the Trezor model T hardware wallets that feature a few new upgrades. One of the most noticeable features is the model T’s RGB LCD touchscreen display that utilizes an RM Cortex-M4 processor. Like the first Trezor model, the new device requires using the screen commands to execute actions tethered to confidential data. Another feature Satoshi Labs reveals is how the model T does not communicate with a computer when entering the PIN and just draws power until you confirm entry. “USB communications are enabled only after authentication,” says the wallet manufacturer.

“When you first hold the Trezor model T, the first thing you will notice is the staple of the model T — its large touchscreen,” explains Satoshi Labs. “Plug your new Trezor in, and the screen will illuminate you, showing off its vibrant colors, waiting for your instructions.”

Definitely something to consider to use alongside my Ledger Nano S. One of the main reasons I never went with the previous trezor is that when you recover your device, the seeds need to be entered via your computer.

With the Ledger Nano S I do everything on the device itself, which honestly speaking is quite a bit of work since you're clicking a lot with the physical buttons, but I always prefer security over convenience.

I can't wait to get my hands on one, but there isn't anything other that I can do than waiting. First shipments are planned to happen January of next year at €139 a pop ~ an insignificant amount when it comes to security.

One of the main reasons I never went with the previous trezor is that when you recover your device, the seeds need to be entered via your computer.

When you enter the seed words into your computer during recovery, they're scrambled in order.  They explain why this is secure on their security threats page:

To summarize, in order to check all possible orderings in a 24-word seed, you need to run SHA-512:
24! ÷ 256 × 8096 = 19621680704813697269760000 times

The bitcoin network is capable of preforming 176 537 883 000 000 000 iterations of SHA-256 each second.

If we wave our hands a bit, we can claim that SHA-512 and SHA-256 are the same difficulty (which they aren’t but let’s pretend they are). Therefore, it should take somewhere around half of:
(24! ÷ 256 × 8096) ÷ 176 537 883 000 000 000 ÷ 60 ÷ 60 ÷ 24 ÷ 365 = 3.5 years

for the ENTIRE BITCOIN NETWORK to crack the seed.

And even if you thought that wasn't secure enough, they have an advanced recovery process in which the letters are obfuscated as well.  It's extremely secure because the TREZOR is used as 2FA.
To me, it looks like the new device is little more than a nice screen.  In terms of actual security features or interesting information it seems to be falling short.  I'll be keeping my old TREZOR for now at least.

I know the process, but I always prefer to input everything on the device itself (I know I am paranoid), which is why this newer trezor model can work out as a decent upgrade where I come from.

It's basically the same level of security overall, but with a bit more convenience (which this time doesn't come at cost of security) due to the touch screen.

For someone with an older device there may not be much incentive to upgrade, but for those who don't, this is the way to go, and that for a reasonable price (assuming you don't end up paying a premium to third party sellers).
