What is a Blockplate?
Blockplate is a tool to permanently store and preserve your bitcoin's wallet recovery seed. In the event your wallet becomes compromised, Blockplates contain the 12-24 words phrase used to restore the funds on your wallet. Each Blockplate stores up to 12 words (6 words on the front, 6 words on the back).
Blockplates currently supports BIP 39 mnemonic format.
Why use Blockplates?
Your recovery seed is the one thing that will save your bitcoin if your wallet fails unexpectedly. It is the master key used to recover your coins if your wallet is destroyed or lost.
Storing it on an electronic device that is connected to the internet (like a phone or computer) leaves your assets vulnerable to hacking methods such as key loggers and screen capture viruses.
Paper and electronics don't last forever and are prone to being disposed of or malfunction.
Blockplates are physical and offline. They are made of stainless steel that can withstand a house fire, physical abuse, flooding, and deterioration. This ensures you have access to your cryptocurrency throughout your lifetime and be able to pass it on to your next generation.
In the event your wallet becomes compromised, Blockplates are there to recover not only your funds but your piece of mind.
What makes Blockplates different than other methods?
Blockplates are the absolute simplest method to store your seed while being minimal and efficient. There is no need to learn how to stamp metal, mess with chemicals, or hassle with tiny pieces.
What are the differences between Blockplate 1.0 and 2.0?
Blockplate (ver. 2.0) features a better stainless steel finish and a deeper and higher quality engraving which endures even tougher physical and environmental abuse.
How many Blockplates come in a pack?
Two. Each storing 12 words (6 on the front, 6 on the back) for a total of 24 words.
Where do I get an automatic center punch?
A center punch is a very common tool in woodworking or machining. They are inexpensive (between roughly $4-$10) and typically have a lifetime warranty.
We offer adding an automatic center punch to your order. But, it may delay your order as we do not carry a high inventory of center punches.
It is much faster (and probably cheaper!) to pick one up at your local hardware store or purchase one online.
I only see 6 words, what gives?
There's a backside too! Each Blockplate stores 12 words in total (6 on the front, 6 on the back to minimize Blockplate's footprint). Blockplates are made from thick (12 gauge) stainless steel plates and each side can be punched safely without damaging the other side.
But I have 24 words!
No problem! Blockplates come in a 2-plate pack allowing you to store 12 words on each plate (24 words total). This gives you the ability to separate your recovery phrase in half and add an extra layer of security.
Why are the plates labeled 1-12 and not 13-24?
If one were to find a plate labeled 13-24, it would alert them that another plate exists. They would have a better chance of finding your other plate than guessing the other 12 words AND put them in the correct order (2048^12 possible combinations). To put it in perspective, there are less stars in the universe than possible combinations.
If someone were to find a plate labeled 1-12, they would have no idea another 12 words exist and your wallet will continue to be secure.
How will I know which plate is 1-12 and 13-24?
With BIP39, if you enter in 13-24 before 1-12, it will register as an invalid seed. Simply swap the order to recover your coins.
But if you plan on storing the the plates together, we recommend punching directly next to the numbers “1” or “2” at the top of the plate to note order of the plates.
Why do I only need the first 4 letters for a mnemonic seed phrase?
Your 12-24 recovery seed phrase most likely comes from the Bitcoin Improvement Proposal: 39 (BIP 39). BIP 39 is the use of a mnemonic phrase -- a group of easy to remember words -- to serve as your back up recovery in the event your wallet becomes compromised.
These words are pulled from a specific list of 2048 words. In this list, the first 4 letters are unique to each word. This means if you have the first 4 letters, you know the rest of the word. Some wallets will even fill in the rest of the word once the first 4 letters are entered.
Why do you not offer international shipping?
We do to specific countries. Our international shipping plans will be on a country by country basis depending on demand and its proximity to the US. This lets us gauge how well our packages are handed off between the US and the receiving country. We’d like to prevent orders being lost or delayed in transit.
If this goes well, we will continue to expand to other international countries.
