Are your assets safe?

In the blockchain industry, when we discuss cryptocurrencies, one of the core issues that can never be avoided is security. One of the characteristics of blockchain-based assets is the public key and private key. The private key is similar to your bank card + password. Whoever owns the private key has the absolute right to use the funds. The public key is similar to a bank card. In the wallet, you can create one or more bank cards for each currency, and the account of each bank card is independent.

How to get hold of your private key

In order to keep our assets safe, we usually store these cryptocurrencies in wallets. It is worth noting that what is stored in the wallet is not the cryptocurrency itself, but the "private key" of the cryptocurrency, which gives you the right to manage these encrypted assets. Wallets can be simply divided into two categories, hot wallets and cold wallets. The full name of the hot wallet is called "the wallet that stores the private key online", and the full name of the cold wallet is called "the wallet that does not store the private key online". The main way to distinguish between the two is to see whether they are connected to the Internet. The hardware wallet we usually talk about does not have a network module. During the transaction process, the information is transmitted by physical means (such as Bluetooth or NFC) to sign the transaction, so the hardware wallet is also a cold wallet.
