A non-fungible token (NFT) is a unique file whose ownership is documented on the blockchain (like a „digital land register“).

A blockchain is a kind of digital land register where property rights can be assigned. It ensures the traceability of related transactions.
The Blockchain is decentralized and therefore not connected to states or banks; however, it is still stored with the highest security standards over a global computer network.

There is no such thing as „the“ one blockchain. The Ethereum blockchain, for example, documents every transaction using the cryptocurrency Ether. With the combination of cryptocurrencies and blockchain technology, assets can be transferred online without the need for an intermediary such as a bank or lending company.

Matic is a cryptocurrency, which is a digital currency used through a cryptographically secured payment system. Your transactions are recorded in the Polygon blockchain.

The term „minting“ comes from real-world coin production. In the crypto context, minting refers to the process of creating tokens from digital assets. The tokens are then registered, so to speak, and the digital art becomes part of the blockchain. As a result, they are immutable, tamper-proof, and can be circulated after this process.

You get a digital asset and the rights to use it. Blockchain technology provides protection for these rights. You will also be granted a right of first refusal (including a reminder) for future NFT drops from DOME COLOGNE NFT.

You will receive a 12 month membership to the Central Dome Building Association for this purpose, which can be renewed after 12 month. It will also be possible to order a high quality Alu-Dibond print in 20×20 centimeters or a GOLD collectors box including a miniture dome.

A wallet can be easily created for free in three steps:

  1. First you need to create a wallet. The easiest way to do that is on Metamask. Metamask guides you through the process step by step. Metamask installs an extension in your web browser (Chrome).
  2. Make sure that you have enough budget. You can buy Matic via bank transfer or credit card – this is similar to exchanging it for foreign currencies.
  3. Then you can connect your wallet to OpenSea. Here, you have to confirm the connection with OpenSea once again in the wallet for security. Done! Now you can go ahead and purchase your NFT!

Wallets are digital wallets that you can use to track your digital possessions as well as receive or send payments. Unlike a physical wallet, neither your property nor your cryptocurrency holdings reside in the wallet. Both remain on the blockchain – the wallet is your gateway to interact.
