Blockchains usually feature individual accounts that are only set up if a transaction to or from it is initiated. Each account is addressed by and consists of a public alphanumerical key public key , which is derived from a matching private key only known to the account owner.

Both keys are cryptographically linked. A correlating public key could be calculated for any given private key but not vice versa, and both keys allow for asymmetric encryption. Only the public key may be stored on-chain as an account number. That may be in paper form paper wallet — a rather unsecure solution on an encrypted external storage device hardware wallet or stored securely on any user device or online by software featuring additional functionality, such as being an interface for sending transactions to the blockchain software wallet.

In the Ethereum blockchain, for example, one of the most commonly used wallets is a software program named Metamask, which is installed as a simple browser extension. Once installed, a new Ethereum account can be generated and the public address is immediately shown. As indicated earlier, no transaction in the blockchain is needed for this. An account is created in the blockchain under this public key only when any cryptocurrency is transferred to the public key.

Multiple service providers meanwhile offer transfer of cryptocurrency against a corresponding amount of fiat currency. In a nutshell, wallets are nothing more than tools for accessing, sending and receiving crypto assets such as Bitcoin or Ethereum.

From the variety of crypto-wallets on the market we decided to use the software-wallet Metamask which we installed as a browser extension of our google chrome web browser. The main reason for this was the fact that the NFT platform OpenSea we used for the placement of our NFT required us to have a software wallet that the respective web applications could communicate with.

What is cryptocurrency and how does it work?

These digital wallets allow you to send, receive, and store cryptocurrency. Like a bank account that holds fiat money basically any paper currency like the US dollar , crypto wallets store digital currencies like bitcoin BTC and ether ETH.

The number is then converted to a private key using the specific requirements of the cryptocurrency cryptography algorithm requirement. A public key is then generated from the private key using whichever cryptographic algorithm requirements are required. The private key is utilised by the owner to access and send cryptocurrency and is private to the owner, whereas the public key is to be shared to any third party to receive cryptocurrency.
