If you invest in cryptocurrency and want to use an alternative currency for privacy or other reasons, you will need a place to store your money and a way to send or receive cryptocurrencies. A crypto wallet is the answer.
Crypto wallets come in many forms, including web wallets, mobile, desktop, paper, software and hardware wallets. Some desktop wallets, so-called full nodes, contain a full copy of the cryptocurrency blockchain.
In short, a full node does the following 3 things:
- Verify transactions
- Share information with other nodes
- Keep a copy of all transactions on the blockchain
