We changed the layout of our Coinplate Grid product to use a bit of encryption that some of our customers asked for.
I wouldn't call this a real encryption, but I guess it could work better for some people, while I prefer regular words myself.
Are there any news and updates regarding Jameson Lopp detail testing of your Coinplate, like we talked about several months ago?
Prices from 74€ to 257€ are a bit to much for my taste for something that was never independently tested and reviewed.
Hi there, it took some time but just a few days ago, Jameson Lopp posted the last round of stress tests and all our products were included.
We received a top, Triple A score for all our products. Just like expected.The stress tests included:
- heating to 2000°F / 1093°C with a propane blow torch and rapid cooling in water
- submerging in a bucket of 16% muriatic acid and left for 12 hours
- using 20 ton hydraulic press to deform it
methodologyYou can check the test results for Coinplate Alpha
here.
It held strong, no data loss of any kind. You can check
our blog post with commentary as well.
https://getcoinplate.com/wp-content/uploads/2022/09/CA-stress-test-comp_c-.pngRegarding the Coinplate Grid type, it depends on the user, some prefer the markings to be less obvious, hence the design. I myself prefer straight and simple solutions like in Coinplate Alpha.
I just wanted to know if the Stainless Steel used for this ....also get what we call "white rust" in our country? Here is a article explaining this :
https://www.metalsupermarkets.com/what-is-white-rust/ ....because the small dent might "fade" if other corrosion takes place on the surface of the plates.
I live in a area where there are a real problem with rust... and I cannot use any product that will be influenced by rust and corrosion for something that holds very sensitive data.
Hi there,
I've checked the article you mentioned and it seems that this applies mostly to regular, carbon steel that is zinc coated. My understanding of this "white rust" is that it eats up a zinc coating. Since Stainless Steel we use is "naked" and has no coating, because it is naturally rust-free, this will be no concern.
You can check the previous post where I linked up to a third-party stress test. It was submerged in 16% muriatic/hydrochloric acid and the product survived it well. Our own tests also show that it holds very well against corrosion. Getting into details, AISI304 steel can get some surface level, minor rusting in sea salt environments after years of use but even there it will not make your seed unreadable. Everything is engraved quite deep and punch marks are also deep enough.
Furthermore, the design holds your seed inside a tight stainless steel sandwich which limits contact with any corrosive agent whatsoever. In the test I mentioned earlier, the acid was applied on an open device and even in that scenario, it survived well.
I do appreciate the effort and that there are many different companies to buy seed phrase backup option, but still I always wonder why so many companies do the exact same thing. There are so many seed backup plates already that are like yours only a piece of steel with some fields on it. Maybe you could tell why your backup solution is better than others on the market?
Like on every market, there are multiple manufacturers because each of them has different ideas on how to achieve the given functionality. Some are focusing on low price, others on high volume production and some are offering sturdy, high-quality products like us.
What I wanted to achieve is to provide simple to use, ultra durable solution to the problem of storing your seed phrase for long time. We aim at durability that will hold your seed safe for 10,20, 30 or more years. If you would like to bury it in the ground, go for it, it will surivve. Would you like to put it inside a wall and forget? not a problem. Our backups are made from super thick plates and engravings are very deep. Also the design protects your seed inside the thick steel sandwich so it is protected from getting scratched or else.
In my opinion most of the devices on the market focus on being just durable enough while being cheap and easy to manufacture. It is not our case, we first thought about making it as durable as possible, not skimping on metal.
Our products weigh a lot, the stainless steel used is actually most of the cost. Other solutions use much less metal and are probably much cheaper to manufacture but 1 or 2 mm plates are not the same in terms of durability as our 2x5mm plates. Also, deep engraving takes a lot of machining time on proper high-power laser machines. You can check the
last round of Jameson Lopp tests to see that other manufacturers often cheap out on this and just etch the markings on the surface so it is destroyed easily.
We went overboard with Coinplate design and made it excessively durable. Coinplate weighs over 2.5 lbs or 1 kg and is made with heavy-duty Stainless Steel. Both plates are 5mm or 3/16″ thick (gauge 6) and are joined together with stainless steel bolts to form a steel slab 10mm or 3/8” thick. This is much thicker than our competitors and we make it that way so you can sleep safe. Coinplates should survive getting run over by a truck as well as being shot with handguns. There is no reason to do that but that means it will survive massive drops or being crushed by a house rubble in case of disaster.
