What is a digital twin?
It is the twin of your physical stamp. You can use it to create your own digital collection. If you do this in the blockchain, you will need cryptocurrency and a wallet.
Can I use the stamp to send post?
The physical stamp can be used for registered letters up to 20 grams sent to an address within the Netherlands.
What about the energy consumption of the NL crypto stamp?
We have chosen Polygon for storing and trading the digital twins. They process transactions using the so-called 'proof-of-stake' principle. This consumes a lot less energy than ‘proof-of-work’, which is what cryptocurrencies like Bitcoin use.
