What is a Blockplate?
Blockplate is a tool to permanently store and preserve your bitcoin's wallet seed (recovery phrase) on strong, durable steel. This is known as metal seed storage.
Blockplate is the original and inventor of "center punch style" seed storage. It was the first of its kind to utilize an automatic center punch to store bitcoin seeds on metal. It has been described as "the fastest and simplest" and "the most robust".
In the event your wallet becomes compromised, Blockplates contain the 12-24 words phrase used to restore the funds on your wallet.
Why use Blockplates?
Your bitcoin 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.
Paper and electronics don't last forever and are prone to being disposed of or malfunction.
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.
Blockplates are physical and offline. They are made of stainless steel that can withstand a house fire, physical abuse, flooding, and deterioration. The engraving is deep, physically removing material from the surface to ensure a long lasting legibility. This ensures you have access to your cryptocurrency throughout your lifetime and be able to pass it on to your next generation.
Blockplate's are unbranded. This means if someone were to find it, they would not be clued in to what it's used for. There are no markings that would indicate its purpose giving you extra time to move your funds. The only Blockplate "branding" is the durability of its construction.
In the event your wallet becomes compromised, Blockplates are there to recover not only your funds but your peace of mind.
What makes Blockplates different than other methods?
Blockplates are the absolute simplest method to store your bitcoin 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 improved from Blockplate 1.0?
The new Blockplates feature a better stainless steel finish and a deeper and higher quality engraving which endures even tougher physical and environmental abuse.
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 at an online marketplace (paid link).
I only see 6 words, what gives?
There's a backside too! Blockplate 12 stores 12 words in total (6 on the front, 6 on the back). Blockplate 24 stores 24 words total (12 on the front, 12 on the back) Blockplates are made from thick (12 gauge) stainless steel plates and each side can be punched safely without damaging the other side.
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.
To clarify “unique”, we mean literally the first 4 letters (not the first 4 different letters). For example the word “apple”, “appl” does not come up anywhere else in the BIP39 wordlist.
For words that only have 3 letters, think of a "space" as a letter. For example, the word “add”, you would leave a space at the end of “add “. The word “addict” is in the BIP39 wordlist but you would have punched “addi” for “addict”.
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.
