New metal seed backup method

[FatFork]

Interesting
I always thought that such backups should be as clear as possible ...

That's exactly the point here. Simple punch holes in the metal plate (representing a binary data) makes them much less susceptible to damage or decay than letters and numbers used in classic backups.

For sure those who dont have idea on what binary is or not really that fan of technicality will surely ignore this one but it isnt really that hard to understand on how to do such thing.

When it comes to storage then this one is indeed tough and wont be easily be destroyed or decipher if someone doesnt know on what it is all about.

The only thing you would mind is not to lose that metal plate.

... Because in my case I know the person I trust is zero literacy about computers. Yes the person know how to surf and send email and use apps but cannot even remember how many times password is reset:)

How will someone with zero computer literacy use cryptocurrency anyway? Sending an email is one thing, but sending and receiving cryptocurrency is something entirely different.
It might be best to train a trusted individual in the basics of cryptocurrency before an unfortunate event occurs.

Ahm uhuh, that's kinda what I was saying the whole time, please read better:) Most people are actually very low on computer literacy (minus surfing and emailing and social media etc, they have no clue about basic computer security let alone digital signing of wallets.

And that's why I think OP's got a really cool and useful product, but it still fails the test for "mainstream" people who you might want to pass your BTC on securely (As this is one use case for this).

For such people then I guess the best solution is a custodial wallet like Coinbase, although I don’t know how they will use even that if, as you say, they constantly forget their passwords.
I don't know why we even discuss such users in this topic? This type of backup technique is an alternative to classic ways, such as writing a seed phrase or private key on a piece of paper, and is obviously intended for advanced users who know what they are doing.

Your comment that this method "fails the test for mainstream people" is equally applicable to all other backup methods.

Where do you find cheap stainless steel plates? I cant find any where I live and online is all ridiculous prices.

I don't know where you live, but few bucks is not ridiculous price, and you can literally find them anywhere in metal shops.

... a binary encoded plate might serve as the backup of the main plate that holds characters in form of letters and numbers.  And each of  both plates could be hidden in the different places thus increasing the probability of SEED restoring in the case of any disaster.

This is indeed how I view this solution. It is another option for people to make a backup of their seeds. It's cheap, doesn't require a lot of tools or hard to get equipment... and unless you live next door to a factory with a large vat of acid towering over your property or near a volcano, it should be relatively hard wearing for all but the most extreme situations.

No reason you can't have one of these AND a "normal" steel backup with words/letters etc... redundant backups are a "good thing"™


Obviously, it's not the best solution for trying to enable recovery by your less than technical heirs... but that's not really the core objective of this particular solution, as far as I can tell.

There are 10 types of people in this world... those that understand binary and those that don't.

Are there other sites that sell cheap stainless steel 304 plates? I'd like them as close to credit card size as possible. Where did OP order his plates? He said they were laser cut too.

I'm ending up doing DIY etching and using steel blocks (the ones used by jewelers), found some on amazon.

I don't know what's wrong with ebay, amazon or any other website, but you can find them easily in your local hardware shop that are selling metal plates, just do your own research for your area.
Alternative for stainless steel plates are washers and screws that are made from same material and you can find them even easier.

I just ordered one from ebay. It should arrive in 2 months or so, it's coming all the way from the other side of the world. Cheap shipping. LOL. We'll see.

I got the 3mm x 100mm x 100mm one so it's as thick as some of the blockplates / seedplates / coldti versions and about 4 inches square.

I read another post someone just got an electrical box cover and stamped that. I might go look at my local hardware store and see. That one is probably galvanized steel, but still pretty heat and water resistant.

You'll be fine, but it's lottery with those slow delivery times.

I saw that post few days ago on reddit I think, and guy who created it said it's strong enough to withstand fire, but he didn't test that like we saw Jameson Lopp and other guys doing.
Generally speaking you'll be fine with both options unless we are talking about temperatures that melted T-1000 liquid metal from Terminator 2 movie

Yeah, I saw that on reddit.

I found another one

Nice, but you still need to play around those holes when you start adding seed words.
My next visit for hardware shop is going to be very interesting, examining everything made from stainless steel, and asking many strange questions along the way
