Alright, let's not beat around the bush:Let's talk about those controversial "stickers" for the Block Height / Block Reward Value numbers...
It looks like I first need to apologize to myself:
Way back, a few weeks ago, I referred to them as "DIY stickers" to be placed on by the customer after the block is mined.
In hindsight, I should have never referred to them as "stickers" at all. I truly regret doing so.
The "DIY" part scared a lot of people.
And the shiny lettering "stickers" part probably made people even MORE upset, as a "stickers" description conveyed a sense of fragility, temporality, and overall cheapness.
Looking back, my description, comments, and subsequent photographs may have caused a LOT of debates about the quality, causing consternation by potential buyers.
I want to apologize myself first, that I choose the wrong words to describe these. It was clearly my mistake to not have explained it adequately from the beginning, as it set things off on a wrong course. Let's hope this post can correct some of that!
Premium Metal Sticker BadgesNow, let me give you all more details, so that you can better assess this before you see it in person.
These "shiny lettering stickers" should have been more appropriately described as "
premium metal sticker badges".
They are VERY similar to the name badges on the back of cars. (Maybe even the same!)
Let me show you how they look on a black Tesla Model S:
Yes, it's true: even a premium automaker like Tesla actually uses self-adhesive metal sticker badges on the back of their cars. But don't worry: the adhesives are industrial strength, and cannot casually fall off or be easily removed.
(Even though I don't know the exact vendor model of what Tesla uses, I am guessing that it's very likely the exact same solution we use. See my descriptions below for more details about our what we use.)
By the way, these industrial "badges" are also commonly affixed to all types of consumer goods and electric appliances. If you go look at your electronics and appliances in your home, I'm sure you'll see plenty of examples of "shiny badges" that are held on using industrial-strength adhesives. I found a lot of examples at my home: on my refrigerator, TV, oven, etc.
Our solution: Metal nickel alloy lettering + 467MP/200MP adhesives made by 3MThe "shiny lettering" material we use is actually made of real metal. It's a nickel alloy.
The more appropriate name would have been something like "
electroforming metal stickers".
So this really is NOT your typical paper or plastics-based sticker coming out of some printing facility.
These are actual nickel alloy metal plates, that's made and processed by advanced machinery. That's why it's shiny on top. It's not a printing effect! They are made using a multi-step manufacturing process, involving films and moulds, electroforming, adhesives, cutting, and quality checks.
See this link for a whole slew of examples (lot of famous brands and companies) who use this industrial solution for their products and branding:
https://www.oemsticker.com/metal-labels/metal-stickers/custom-nickel-electroforming-plate-embossed.htmlThe "adhesive" is an industrial-strength solution made by 3M. The actual model name is 467MP/200MP.
The 467MP is the name of the transfer tape, for industrial application use.
The 200MP is the name of the adhesive. It's only 0.06 mm thickness, yet super strong.

3M™ Adhesive Transfer Tape 467MP
3M™ Adhesive Transfer Tape 467MP provides outstanding adhesion to metal and high surface energy plastics. 200MP adhesive delivers excellent shear strength to resist slippage and edge lifting. The tape is temporarily repositionable for placement accuracy. It also performs well after exposure to humidity and hot/cold temperatures. A PCK layflat liner helps prevent curling and buckling in the liner.
Excellent for Bonding to Metals and HSE Plastics
We've designed 3M™ Adhesive Transfer Tape 467MP with a 2.3 mil thick adhesive for applications such as splicing and laminating procedures using metals and HSE plastics. This high-performance adhesive delivers excellent shear strength to resist slippage and edge lifting. It is mounted on 58 lb. polycoated kraft paper liner which virtually eliminates curling, rippling and buckling and provides efficient release. This adhesive transfer tape resists solvents, humidity and moisture, as well as heat (up to 400°F/204°C for short periods).
Featuring 3M™ High Performance Acrylic Adhesive 200MP
More than 30 years ago, 3M High Performance Acrylic Adhesive 200MP set the standard for bonding metal and high surface energy plastics. Today, this high-performance adhesive provides even higher levels of performance, with exceptional peel and shear strength for precision bonding. It offers excellent moisture and solvent resistance which enable it to form resilient, durable bonds that conform to a wide variety of applications. Once bonded, this adhesive will provide outstanding shear strength to resist edge lifting and slippage. 3M™ High Performance Acrylic Adhesive 200MP also offers excellent short-term heat resistance and will continue to perform at temperatures up to 400°F/204°C.
Recommended Applications:
- Long term bonding of graphic nameplates and overlays ("subsurface" printed polycarbonate or polyester) to metal and high surface energy plastics
- Bonding metal nameplates, serial and rating plates
- Bonding graphic overlays for membrane switches and bonding complete switches to equipment surfaces
- High speed processing of parts (medical components, durable labels, flexible circuits)
- Lamination to industrial foams for rotary die-cutting of gaskets
- Aerospace, medical and industrial equipment, automotive, appliance and electronics markets
Features:
- 2 mil nominal adhesive tape delivers exceptional shear strength for metals and HSE plastics
- Provides very high resistance to solvents and humidity
- Special PCK layflat liner for increased dimensional stability in high humidity storage, processing, shipping and application conditions
- 4.2 mil PCK layflat liner virtually eliminates curling, buckling and rippling
- 200MP acrylic adhesive is considered the industry standard for graphic attachment and general industrial joining applications
- Temporarily repositionable adhesive improves placement accuracy, reducing rework

Here's the actual real metal lettering for Block #2 (made of nickel alloy).
Thank you for taking the time to read all of this.
Hope that this additional information can give you more confidence in our solution.
Yes, our process still requires you to physically put these metal stickers on the block. It's actually quite easy, and we will provide detailed instructions and placement guides. (Alternately, you can also choose to not put them on for now, and just keep the set of metal sticker badges in the box, and store it together until later.)
Or, if you come to Las Vegas, please come visit our facility, and I'm happy to have my staff do it for you. And alternately, if you really choose to, we can also laser etch the numbers onto the blocks for you. However, I truly do think that the metal sticker badges look way better than a laser etching.
Let me know if you have any more questions.
thanks,
Bobby
PS - I hope to have the final photos of a completed block, to show you within a few days. It'll show the full effect of the custom metal sticker badges applied. Stay tuned.
